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.

Hankook iON Race Proves Critical In Chaotic Tokyo E-Prix Double-Header
- By TT News
- July 31, 2026
Hankook Tire, the exclusive tyre supplier for the ABB FIA Formula E World Championship, played a central role in the season’s pivotal Japanese double-header. As the official race tyre for all competitors, the company’s iON Race compound was put to the test under extreme and shifting conditions during Rounds 14 and 15 of Season 12 at the 2026 TDK Tokyo E-Prix.
The weekend’s on-track action produced two dramatic winners. CUPRA KIRO’s Dan Ticktum snatched victory in Round 14 with a last-corner overtake on Jake Dennis, while Nick Cassidy completed the podium. The following day, Mahindra Racing’s Nyck de Vries claimed Round 15, finishing ahead of Cassidy and Dennis, who secured second and third respectively. The entire paddock also observed a period of remembrance for the late Cyril Blais.

The 2.575-kilometre temporary circuit, featuring 18 corners and situated around Tokyo Big Sight, hosted its first-ever night races, drastically altering track conditions from practice to competition. Unstable weather compounded the challenge, with a Sunday thunderstorm cancelling Free Practice 3 and leaving a damp, drying surface for Round 15 that demanded constant adaptation in tyre warm-up and strategy.

Throughout the weekend, Hankook’s iON Race tyre demonstrated reliability across the evolving grip levels and temperature swings. Following the Tokyo results, Dennis retains the championship lead with 146 points, narrowly ahead of Mitch Evans and Pascal Wehrlein. The title battle remains fiercely contested and will be resolved at the season-ending Hankook London E-Prix double-header on 15–16 August.
Manfred Sandbichler, Senior Director, Hankook Motorsport, said, “Bringing Formula E night racing to Tokyo for the first time made this a distinctive weekend and one of the more unusual tyre assignments of our season. The contrast between afternoon running and the 20:05 races shaped how teams prepared for both events, and the iON Race managed that transition and the changing weather conditions well, delivering consistent and predictable performance as the circuit cooled through the evening.”
Tegeta Green Planet Champions Circular Economy At EU-Backed Youth Camp
- By TT News
- July 31, 2026
Tegeta Green Planet recently contributed to the ‘Circular Future’ green camp, an environmental education initiative organised by CENN and funded by the European Union. The camp, which hosted 23 teenagers from the Adjara and Kakheti regions, was designed to deepen ecological understanding, advocate for waste-free systems, and inspire long-term behavioural change among the next generation.
Throughout the week-long gathering, young attendees engaged with forward-thinking methods for minimising refuse, prolonging product life cycles and improving separation and recovery processes. Interactive workshops translated abstract circular economy theories into tangible daily actions, equipping participants with the know-how to conserve materials and shrink their personal environmental toll.

A noteworthy component of the programme occurred on 22 July, when a specialised seminar titled ‘Circular Economy: Waste Reduction and Recycling for Public Health’ was convened. Co-hosted by Tegeta Green Planet, the UNDP and the Waste Management Business Association, the seminar examined the intersection of ecological integrity and human well-being, illustrating how robust recycling systems directly benefit community health outcomes.
Closing the day’s agenda, Tegeta Green Planet’s Director, Shalva Akhvlediani, offered an in-depth look at the Extended Producer Responsibility model currently unfolding in Georgia. He traced the journey of end-of-life vehicle components – from used tyres and spent lubricants to depleted batteries – through collection, transport and reprocessing channels. Akhvlediani also highlighted his organisation’s network of over 350 domestic producers and importers, stressing that youth education remains a cornerstone of their mission. The floor was then opened for a lively exchange, where students posed probing questions, debated local environmental dilemmas and floated their own grassroots suggestions, reinforcing the message that responsible resource use begins with informed individual choices.
