Specialised high-precision manufacturing company Glebus Alloys has been a preferred partner of leading tyre companies across the globe for over two decades. 

Its mission was clearly defined by its founder Michael Stefanidis: “Our aim is to make manufacturing a safer place for the worker and more profitable for the shareholders by sustaining a greener and cleaner industrial environment.”

Glebus has three product lines: G-METAL, GSV and DOT Plugs.

G-METAL

Located in Poland, the company’s plant produces maintenance free, self-lubricated bearings, sliding plates and bushings under the trade name/mark of G-METAL and CERAMET.

It is a specialised material that combines unique properties for the curing department. Companies like Goodyear, Bridgestone, Michelin, Pirelli, Continental, Cooper, Hankook, Yokohama, MRF, JK Tyre and others have been benefitting from Glebus Alloys’ sliding plates for long time.

The company employs over 140 people with over four decades of combined experience in tyre curing and mould handling. Glebus Alloys takes prides in its fast, dependable and customised JIT services. It has developed products in different areas for the container shoe, top and bottom plates, axial movements and higher loads segments. 

An added value is the 5-year warranty that Glebus Alloys provides. The factory has two production sites – one for continuous sintering and one for customer sintering process – that enable it to offer high quality materials at affordable prices along with fast delivery customised to client drawings and specifications.

One of the key factors for a perfectly cured tyre is the proper closing of the mould in the container and press. Any misalignment among the three moving elements will harm the outcome of the curing process.

These misalignments, in most cases, come from the wear out of the sliding plates and guiding elements. Specially developed wear indicators can be placed on the wear plates to maintain the proper replacement period. Based on the extensive period spent in the tyre industry, Glebus Alloys has developed a self-lubricating sliding material suited especially for tyre containers. 

Glebus Alloys does not spray its wear plates with specialised coatings to make them look like sliding material. Glebus Alloys sinters and bonds its unique formulas to have a unified unbreakable material.

G-METAL self-lubricating sliding plates are especially designed to cope with unevenly distributed load and thus provide prolonged production time. Used in tandem with the wear indicators, it allows to stay on top of the issues caused by blocked container due to worn out sliding plates.

Furthermore, long raw material bi-metal wear plates of size 2,000x200 mm with a total thickness 3 or 5mm for individual custom projects are now available for order. 

GSV

Glebus Alloys is the ‘only’ worldwide patent holder for the tyre mould venting systems under the brand name GSV (Glebus Spring Vents). 

The unique demountable, three-piece design of the GSV provides a lot of flexibility that older spring vents (the one-piece type) are not able to match in anyway. 

Glebus Alloys starts by evaluating the current situation and status of the tyre curing environment and finds solutions on how companies can develop a manufacturing place for tyres with free spew, greener and less expensive. Glebus Spring Vents may replace existing vents (microvents-minivents) in the same hole and eliminate the need for expensive vacuum containers or press piping or injection type segmented moulds.

This product line employs 70 people with over 100 years of combined experience in rubber compounding, mould designing, mould manufacturing, mould cleaning and tyre curing.

The new development includes specialised stems that are focused on the surface of the aluminium mould and the machined top that is imprinted on the tyre surface. The focus on the visual aspect of the tyres has become very demanding nowadays, resulting in different stem head textures.

This development has been going on for some time now and results show that this can be amended by proper adjustment of surface parameters like different coatings, artificial increase of surface roughness to break the light reflection and special machining. 

New addition to the GSV portfolio are the specialised stems that offer customised approach to deaeration of sidewall plates during curing process due to different flow of rubber. 

DOT Plugs

RGP, a subsidiary of Glebus Alloys, is a specialised plastics production company based in Czech Republic. It is focused on specific industries and high-end precision thermoplastic projects. This is the company’s third line of product – nano-plastic DOT plugs for tyre moulds that replace aluminium or steel one. This company employs 40 people with knowledge of AI and 4.0 automation.

Pirelli is all set for the winter season with its winter tyre range that is renewed over the past two years. The newly launched Scorpion Winter 3 joins the P Zero Winter 2 for high-performance cars and the Cinturato Winter 3 for saloons and crossovers. The range is available with Pirelli Elect technology for electric vehicles. Independent tests by European organisations have placed Pirelli winter tyres at the front in safety-related areas, while the Cinturato All Season SF3 has recorded four victories and six additional podium finishes.

Winter tyres or suitable equipment are required from 15 November to 15 April. Most winter driving occurs on dry and wet roads. Below 7°C, winter compounds offer more grip than summer compounds, and the tread pattern helps counter aquaplaning and generate traction on snow. Sidewall markings indicate capability: M+S identifies a product for challenging surfaces, while 3PMSF certifies testing in harsh conditions. An appropriate winter driving style includes increased safety distance, avoiding sudden acceleration and reducing brake use in favour of engine braking.

The Cinturato Winter 3 took first place in the 2026 ADAC winter tyre test in size 225/50 R17 against 16 models, earning a highly recommended rating with the best wet score and the highest assessment for driving safety. It won the AvD test in size 225/45 R17 against 15 tyres with a very good rating. It also finished first in the Auto Bild comparison in size 205/55 R16 on a Volkswagen Golf against 14 tyres with an exemplary rating. Podium finishes followed in tests by Auto Express, Auto Bild Allrad and Tyre Reviews, giving six podium finishes in seven tests, including three victories.

The Scorpion Winter 3 debuted with a victory in the alVolante comparison in size 235/60 R18 on an Alfa Romeo Stelvio, ranking first among six winter tyres. Its wet performance, shortest braking distance, fastest lap time and progressive reactions set it apart. It was judged consistent and predictable on snow and balanced on dry roads.

In the annual Auto Bild super comparative test, the P Zero Winter 2 finished on the podium with an exemplary rating, thanks to precise driving behaviour in wet and dry conditions and braking performance on both surfaces. The Cinturato Winter 3, Scorpion Winter 3 and P Zero Winter 2 are available with Pirelli Elect technology on dedicated fitments for Europe's electric vehicle fleet. Elect addresses low rolling resistance for range, acoustic comfort, longer tyre life, grip for immediate torque and a reinforced structure for battery weight.

All-season tyres suit drivers mainly in urban areas covering up to 20,000 km per year without frequent heavy snowfall. Higher mileage, regular mountain travel or high-performance cars generally call for winter tyres. The Cinturato All Season SF3 carries the 3PMSF marking and has four victories in comparisons by Auto Zeitung, Reifentester, Auto Express and Que Choisir, plus six additional podium finishes. The new Scorpion All Season SF3 extends the approach to SUVs.

Nokian Tyres will withdraw its sponsorship of the 2027 IIHF Ice Hockey World Championship should Russia be permitted to compete, the company has confirmed. The decision follows a Court of Arbitration for Sport (CAS) ruling that cleared Russian national teams to return to international ice hockey. Nokian Tyres stated that continuing the sponsorship under such circumstances would conflict with its values. Tiina Frazer, SVP of Brand, Marketing and Communications, explained that while the 2026 tournament cooperation proved highly successful, the company felt compelled to act on its principles regarding Russian participation.

The tyre manufacturer had been named an Official Sponsor for both the 2026 and 2027 IIHF Ice Hockey World Championships in late 2025. Its 2026 involvement included the ‘Carve the Corners’ contest, running from 6 February to 20 March, which offered fans in the United States and Canada a chance to win a trip to the tournament. The 2026 event, held from 15 to 31 May, featured 64 games with 16 top national teams competing for the title and stands as the world’s largest annual winter sports event.

Frazer said, “Our sponsorship agreement with the IIHF covers the 2026 and 2027 World Championships, and our cooperation around the 2026 tournament was very successful. However, under the current circumstances, continuing the sponsorship if Russia participates would not be aligned with our values. We have therefore decided to end our sponsorship of the 2027 World Championship should Russia be allowed to take part.”
