Rubber presents a challenge for optical-based measurement sensors. By nature, the black surface is difficult to capture reliable data from and accurately measure. This challenge is often intensified by the complex shapes into which rubber derivatives are extruded or molded.

As a solution to this challenge, 3D laser sensor manufacturers have optimised the design of their sensors to successfully implement scanning and quality control functions for both in-process and final product inspection applications in rubber and tyre manufacturing.

3D laser scanning

Rubber material comes in two forms on the production line, either as fresh and uncured from an extruder or a calender, or as a finished product (e.g., vulcanised tyres). Non-contact 3D laser scanning offers the most practical solution for inspection of both of these rubber material types.

Here’s why:

1. The soft, gummy nature of the rubber makes contact-type measurement ineffective. This measurement approach is also too slow to keep up with the high-speeds of continuous web material production.

2. 2D sensors require complex lighting to see black-on-black contrast. In some applications the lighting is placed underneath the material (e.g., when measuring the width of a strip), and hot sticking rubber can contaminate the lights. In addition, 2D can’t produce measurements related to object geometry (i.e., 3D shape), which means they are unable to measure critical features such as object flatness, surface angles, or part volumes, and are limited to contrast-based inspection. This makes 2D sensors a poor solution for scanning complex shape-based features on dark surfaces, or for operation in low lighting conditions.

          3. In comparison, 3D laser sensors are contrast invariants and generate high-resolution scans regardless of the material or lighting conditions. They also capture the complete 3D geometry of the scan target, including critical depth measurements on surface features such as grooves in a tyre tread. 3D laser sensors are also able to achieve the high speeds required for continuous web material scanning.

Laser profile sensors provide an ideal solution to both in-process and final rubber and tyre measurement and quality control applications. Built-in measurement tools for strip positions, including multiple groove location and depth measurement monitoring with automated alignment enable engineers to configure setup parameters––without requiring any measurement software development.

In addition, the ability to store multiple geometry configurations in the sensor makes changes between different recipes quick and simple, which is critical in minimising downtime for operations that make model changes multiple times per shift.

Application examples

1. In-Process Inspection

Extrusion Profiling with High-Resolution Gocator® 2440 Laser Profiler

Extruding rubber in a specific shape makes up the tread portion of a tyre. Measurement of the extrusion profile is carried out in-process, correcting the extrusion parameters in real-time to maintain the required shape. Key measurement parameters include thickness, width, and profile. Another required sensor capability is monitoring the position of surface features, such as ridges, center lines, and edges.

Profiling these tread extrusions is done by using 3D laser sensors to scan across the extrusion, generating a profile to which built-in measurement tools and pass/fail decision-making logic can be applied.

In this example, two Gocator 2440 laser line profilers are used to measure the rubber web’s extrusion groove pattern, geometry, and location with an X resolution down to 13 microns. Gocator 2440 sensors are able to inspect multiple grooves in a single setup, and groove measurements are unaffected by changes in surface angle relative to the sensor.

Most importantly, Gocator 2440 sensors generate critical 3D height data for robust shape measurement. 2D solutions are limited to contrast-based inspection.

3. Final tyre inspection

Tyre Sidewall Inspection with High-Speed Gocator 2530 Laser Profiler

Traditional methods for measuring tyre sidewalls for defects such as bulges and dents suffer from too many false rejects (i.e., classifying a good tyre as defective). Due to measurement system limitations, many manufacturers have no choice but to “oversensitise” their sidewall bulge and dent measurement systems, resulting in costly manual inspection requirements for all rejected tyres.

In fact, some measurement systems cannot even distinguish between bulges or dents. However, with state-of-the art laser measurement precision and advanced built-in software analysis, false positive rates can be substantially reduced and, in many cases, eliminated altogether.

Using a Gocator 2530 laser profiler the engineer is able to generate full surface point cloud geometry data in order to detect small defects (down to 28 microns X resolution) anywhere on the sidewall surface. The sensor also delivers complete scan, measurement, and control at 4 kHz, allowing engineers to meet stringent cycle time requirements––with no need for industrial PCs or external controllers.

In this configuration, two profile sensors are typically used, one for each sidewall (top and bottom buddy system). A third sensor is often used to monitor radial runout of the tread.

Leveraging 3D Laser Scanning and Inspection

Laser-based laser triangulation sensors meet the high speed and high resolution requirements for accurate rubber and tyre measurement. These sensors are used in a variety of in-process and final inspection applications, including extrusion profiling and tyre sidewall inspection.

Adding 3D laser sensors for automated quality control is vital to reducing scrap and rework, and improving final product quality by maintaining consistency throughout the tyre manufacturing process.

India’s mounting tyre waste problem has found a determined challenger in Home Zone Rubber Solutions, a young but ambitious company from Vapi, Gujarat. Founded just four years ago by stainless-steel-industry veteran Jitendra Agarwal, the recycler has quickly scaled to processing more than half a million scrap tyres annually with plans to double capacity through an upcoming IPO. Armed with cutting-edge Danish Eldan technology and a vision that blends environmental responsibility with industrial innovation, Agarwal is positioning Home Zone not just as a recycler but as a pioneer of India’s circular economy in rubber.

Home Zone Rubber Solutions, headquartered in Vapi, Gujarat, is rapidly establishing itself as one of India’s foremost tyre recycling companies. Established just four years ago by Managing Director Jitendra Agarwal, the company’s roots trace back to a legacy in stainless steel manufacturing. However, post-pandemic, Agarwal saw an opportunity to pivot towards environmental sustainability through tyre recycling owing to its immense potential but significant challenges.

Speaking exclusively to Tyre Trends, Agarwal said, “Our family has always been in the stainless steel business, but I have long been passionate about environmental issues and recycling. When the opportunity presented itself after lockdown, we grabbed it with both hands.”

Today, Home Zone processes around 5,000 tonnes of scrap tyres every month, which translates to over half a million tyres annually. Agarwal shared that with an upcoming initial public offering, the company plans to double this capacity, targeting recycling of up to 10 million scrap tyres annually.

“This is a huge achievement because tyres are among the most hazardous wastes worldwide. They can take 150 to 200 years to decompose if left unchecked. They pollute landfills and oceans alike, so taking millions of tyres off the roads and recycling them is vital to protecting our environment,” Agarwal explained.

INNOVATIVE METHODOLOGY

At the heart of Home Zone’s process is a sophisticated tyre recycling line sourced from Denmark, known as Eldan. This machinery stands out as one of the most advanced globally, capable of reclaiming 99.9 percent crumb rubber granules from shredded tyres, claimed the executive.

“Separating components like steel is fairly straightforward, but the fibre and rubber separation is incredibly complex. Our line is the only one currently in India with a full Eldan setup, and it delivers unparalleled efficiency and quality,” Agarwal said.

The crumb rubber generated is classified in mesh sizes in granular levels ranging from 5 up to 20 mesh currently. The company is working towards finer mesh granules going up to 40 and eventually 80 to 120 mesh, which are essential for manufacturing new tyres from recycled material. Agarwal notes that this progression is gradual given the technological challenges of grinding tyres to such fine granularity in a controlled environment.

The applications for crumb rubber extend beyond new tyres. The company’s crumb rubber is widely used in diverse sectors including sports turf grounds, anti-slip tiles, automotive components, conveyor belts, industrial footwear and infrastructure projects.

The company maintains a research and development team, including experts in robotics technology, to ensure product quality and innovation. “As we move into finished products ourselves, quality testing and consistent innovation are vital,” Agarwal stressed.

One particularly unique product is the cow mat, exported from India to dairy-producing countries worldwide. Made from crumb rubber, these mats improve cow comfort, reduce blood pressure of animals and consequently increase milk production. This innovation exemplifies how recycling can impact even agricultural practices.

MARKET WATCH

While Home Zone currently primarily serves the domestic market, exports are an important growth area. Plans include selling crumb rubber and finished mats to markets in the Middle East, Europe and China. Agarwal sees China as a significant opportunity, especially for finished rubber products rather than just raw crumb rubber.

To support this expansion, the company has identified a 25-acre land parcel near Mundra port, approximately 9.5 kilometres from the port itself. This facility aims to be a fully integrated recycling and manufacturing hub, where crumb rubber will be processed into finished products before export. The target for beginning operations is late 2026.

Furthermore, while India remains the third largest generator of scrap tyres globally, Agarwal pointed out that the supply of these tyres for recycling is fragmented and inefficient, forcing Indian recyclers to import scrap tyres from the US and Europe, often at lower costs due to government subsidies and more streamlined collection systems abroad.

To tackle this, Agarwal has launched Re-Tyre Bazar, India’s first organised scrap tyre collection network. Initially rolling out centres in states like Tamil Nadu, Telangana, Rajasthan, Maharashtra and Madhya Pradesh, this initiative aims to consolidate the fragmented supply chain and enable recyclers to source Indian scrap tyres exclusively in the near future.

“If we can organise this chain effectively, we won’t need imports except as a bonus. That would validate the model and mark a major step forward for the Indian recycling industry,” Agarwal said.

Re-Tyre Bazar operates as an independent company and is intended to serve the entire Indian recycling sector, rather than being exclusive to Home Zone Rubber Solutions.

FOCUS VIEW

Agarwal highlighted that about 70 percent of Indian scrap tyres come from the truck and bus segment. “TBR scrap tyres generally lend themselves to higher quality  recycling applications, compared to passenger car tyres,” he explained. This focus area presents significant opportunity for the company as it scales production and refines crumb rubber quality.

Addressing common misconceptions about tyre quality, he stated, “Many believe that American and European tyres are superior, but it’s not true. Indians may even have a 5 to 10 percent advantage due to how tyres are used and road conditions.”

He was also candid about rumours that some importers misuse scrap tyre imports licenses, selling raw material rather than using it in production. “Such misuse is limited to a small minority, but government agencies must enforce regulations strictly to protect industry credibility,” he said.

On the regulatory front, Agarwal views government initiatives such as Extended Producer Responsibility (EPR) as positive developments that place recycling obligations on tyre manufacturers. However, careful enforcement is needed. He also advocates for consumer awareness campaigns and incentives like green labelling for recycled products.

“Consumers want environmentally friendly choices. A green label on products made from recycled rubber could boost demand and support the circular economy,” Agarwal noted.

FUTURE PROSPECTS

The upcoming IPO is a major step towards funding Home Zone’s expansion. Public filings indicate the company aims to increase production capacity from around 57,000 metric tonnes annually and invest in new machinery and facilities.

“We expect the next decade to be very exciting for the industry,” Agarwal said confidently.

Reflecting on the company’s environmental mission, Agarwal concluded, “We inherited this planet from our parents and grandparents. If we cannot leave it better, let us at least leave it as we found it.”

Ian Andrews steps into the role of NTDA Chief Executive at a precarious moment for the UK tyre industry, where skills shortages, demographic shifts and mounting environmental pressures threaten to outpace the sector’s readiness. New to tyres but not to membership organisations, Andrews must prove his ability to turn fresh perspective into actionable solutions bridging gaps in recruitment, diversity and sustainability while convincing members that the nearly century-old association can adapt quickly enough to safeguard its relevance.

Ian Andrews, the newly appointed Chief Executive Officer of the National Tyre Distributors Association (NTDA), has embarked on a mission to address urgent challenges within the UK tyre sector, undertaking a comprehensive strategy to tackle recruitment issues, enhance member engagement, promote collaboration and advance environmental sustainability.

Coming from two decades of senior leadership in membership-based organisations but new to the tyre industry itself, Andrews brings a fresh perspective combined with seasoned leadership skills to the nearly 100-year-old trade association.

Upon assuming his role, Andrews emphasised a grounded approach focused on learning directly from NTDA members. “My immediate priorities are to understand the challenges and opportunities that face the tyre sector here in UK, principally, but globally as well,” he shared.

Approaching the role without preconceived notions, he aims to listen and respond to member feedback. Early indications point to recruitment and careers as pressing issues. “Careers and recruitment seem to be one of the early areas of work that we need to focus on. There are significant recruitment issues here in UK, not just in tyres but across the whole motor vehicle sector,” said Andrews during the exclusive interview with Tyre Trends.

TACKLING GAPS

The UK tyre sector faces a looming demographic shift with a substantial number of experienced professionals expected to retire over the next decade, risking a critical loss of institutional knowledge and technical skills.

Andrews warned, “The sector has got a significant number of people who will retire in the next 10 years. So there’ll be a significant loss of knowledge and skills.”

While larger companies have training and HR departments to manage recruitment and development efforts, smaller businesses face a heavier burden. “They are doing it themselves, and if you’re employing somebody new, then it’s a huge commitment to train and develop that person until they start generating revenue and making a return on the investment,” he explained.

Recognising the sector’s traditionally male-dominated nature, Andrews stressed the imperative of building a more diverse workforce. “We need to look at getting a better and more diverse workforce. Moreover, any business should be reflective of the community it’s working in. If you’re in an ethnically diverse community, your workforce will be best when it’s ethnically diverse,” he noted.

Yet he acknowledged the cultural shift required will take time and that’s not going to happen overnight.

Furthermore, Brexit has complicated recruitment by reducing access to talent from Europe, shifting the focus predominantly to UK-based recruitment. “Most of the tyre sector focus is on UK recruitment, perhaps more so now after Brexit,” Andrews noted.

Despite these constraints, his message was clear: “If we keep doing what we’ve always done, we’ll end up with what we’ve always had. So we need to look at doing different things. Reaching different groups of people.”

To address the skills and professionalism gap, NTDA has expanded its tyre technician licensing schemes significantly. Andrews reported robust uptake with over 16,000 technicians licensed by the NTDA.

This growth is particularly notable in the past two years. Acknowledging the specialised skills needed in emerging technologies, he highlighted the introduction of licensing for electric vehicle tyre (EV) technicians. “The whole electric vehicle is bringing a new plethora of challenges and opportunities. It’s a different skill set. Everything is different in EVs,” he said.

ENGAGING MEMBERS

Member engagement and retention stand as foundational pillars for Andrews’s leadership as well. He aims to increase members’ awareness of

NTDA’s benefits and encourage their active participation. “Often, members pay their membership fee but don’t really explore all the member benefits,” he observed.

Plans include surveying members on their benefit awareness and usefulness while exploring additional services that may be introduced. To foster greater connection, Andrews is looking at enhancing local engagement through regional events across UK, alongside leveraging digital platforms.

He mentioned, “We run large national events in October, including our National Tire Conference and National Tire Awards, which are very well supported. But we need to explore how else we can engage with members on a more local basis for physical events but also on a digital basis.”

His previous experience includes organising half-day digital forums with speakers and interactive participation, offering participants the flexibility to attend live or watch recorded sessions later.

Collaboration within the sector forms a cornerstone of Andrews’s strategic outlook. While mindful and cautious of anti-competitive regulations, he believes substantial benefits can come from sharing resources and best practices, especially on recruitment and sustainability challenges.

“There’s always greater advantage in collaboration than there is in competition. Who is doing it well? What are they willing to share? What resources do they have that might be made more widely available?” he asserted.

At the same time, he acknowledged the necessity of protecting commercially sensitive information: “There will always be things that are commercially sensitive and need to be kept such, but that’s fine. Let’s collaborate on the 90 percent that isn’t commercially sensitive and keep the 10 percent that is.”

ENVIRONMENTAL STEWARDSHIP

Environmental stewardship and sustainability have emerged prominently on the NTDA agenda. Andrews described active engagement with the UK Environment Agency regarding the management of end-of-life tyres.

“We’re engaged with the agency that is responsible for where end-of-life tyres end up, making sure that they end up in the right place at the right time and don’t clog up our rivers, canals and green spaces,” he stated.

Growing government interest in tyre runoff impacting watercourses may further intensify oversight. “There’s government interest in where runoff from tyres is ending up in the water courses,” Andrews noted, emphasising the importance of proactive dialogue. “With all aspects of working with government, it’s about getting to them before they get to you.”

He committed to openness and transparency if issues arise, stating, “If there’s an issue, then be upfront and open that there’s an issue and we’re working on it and there is a solution.”

Looking to the future, Andrews identified his plans for NTDA’s next three to five years that include member growth, recruitment and environmental awareness. “Internally, it is driving member engagement and member value and therefore driving up member growth,” he shared.

Externally, recruitment and environmental matters are key concerns. Noting that larger companies typically have sustainability specialists, Andrews highlighted the need to support smaller businesses struggling to navigate sustainability practices. “Helping the whole sector regardless of the size of the business is important,” he said.

Throughout the interview, Andrews repeatedly underscored the fundamental role of the tyre industry in public health and safety. “The tyre sector is fundamentally about health, safety and well-being,” he emphasised.

“You wouldn’t put your most precious things anywhere without some assurance that they’re going to be safe. Let’s not put our partners, children, parents into vehicles without some assurance that the tyres are going to do the job that’s expected of them,” he asserted.

Based in Halesbury, Buckinghamshire, Andrews expressed enthusiasm for leading the NTDA forward. While new to tyres, he is confident in his ability to learn quickly with the board and executive council’s support. “The tyre stuff I will learn. When I joined the BPCA, I knew nothing about pest control. Now I’d like to think the same will be true of tyres. It’s all learnable,” he said.

He also stressed his readiness to bring expert colleagues to discussions, for example, when facing government ministers, to ensure the expertise needed is present.

As he takes charge of NTDA during a time of transformation, Andrews seeks to position the association as the collective voice of the tyre sector, delivering professional standards and fostering a collaborative, diverse and sustainable industry that prioritises safety and well-being.
