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.

JK Tyre Finalises Cavendish Merger
- By TT News
- December 23, 2025
JK Tyre & Industries Ltd. has formally completed the merger of its subsidiary, Cavendish Industries Ltd., into its operations, a strategic move that follows Cavendish's acquisition in 2016. At that time, Cavendish was operating at only 30 percent of its manufacturing capacity for various vehicle tyres. Under JK Tyre's stewardship, the subsidiary received extensive managerial, financial and technical support, which facilitated a complete operational turnaround. Through optimised manufacturing processes, capacity utilisation dramatically increased to 95 percent. Additional expansion at the Laksar facility further bolstered its substantial contribution to the company's overall tyre production.
This consolidation is projected to generate significant value by combining operational strengths, achieving greater economies of scale, and creating a more robust and diversified product portfolio. The unified entity will also benefit from an extensive, integrated distribution network. The merger aligns with JK Tyre's enduring strategy of pursuing sustainable growth through both organic projects and strategic acquisitions. Cavendish’s successful integration represents the company’s third major operational turnaround, following previous revitalisations of Vikrant Tyres and JK Tornel Mexico, alongside the establishment of two Greenfield plants.

Hankook Tire Earns ISCC PLUS Certification For Daejeon Plant
- By TT News
- December 23, 2025
Hankook Tire has further solidified its commitment to sustainable manufacturing with the recent International Sustainability & Carbon Certification (ISCC) PLUS awarded to its Daejeon plant. This globally recognised certification validates the use of bio-based and recycled materials and ensures supply chain transparency, representing the company’s third such achievement following earlier certifications at its Geumsan and Hungary facilities. At the Daejeon site, the substitution of fossil-based synthetic rubber with bio-circular polymers has substantially lowered the environmental impact across the entire product lifecycle.
This milestone reinforces Hankook Tire’s comprehensive ESG strategy, which now encompasses original equipment, replacement and motorsport tyre production. A notable example is the supply of high-performance rally tyres, incorporating up to 31 percent sustainable materials, for the 2025 FIA World Rally Championship. The company’s sustainable innovation is also evident in products like the iON evo tyre for the Porsche Taycan, which uses 45 percent recycled and recyclable materials without compromising performance. Similarly, the iON GT replacement tyre for the European market integrates up to 77 percent certified materials and has earned top EU Tyre Label ratings.
Beyond product development, Hankook Tire is pioneering future mobility solutions, showcased by a concept tyre with 81 percent sustainable materials presented at IAA Mobility 2025. In electric motorsport, as the exclusive tyre supplier for Formula E, the company has earned the FIA’s highest environmental accreditation and is set to introduce the iON Race tyre containing 35 percent sustainable materials.
To accelerate these efforts, Hankook Tire is pursuing open innovation through collaborations with technology partners such as ROTOBOOST and Solvay, focusing on advanced materials like turquoise hydrogen-based carbon black and circular silica. The company is also engaged in national research consortia to validate carbon-reduction technologies and enhance the commercial readiness of sustainable alternatives, consistently aiming to merge high performance with ecological responsibility across its global operations.
Bridgestone India Revitalises Kuti Village School In Indore District

Bridgestone India has reconstructed and revitalised the government school in Kuti village, near the National Automotive Test Tracks (NATRAX) in Madhya Pradesh, under its Corporate Social Responsibility (CSR) initiative. The project directly serves a marginalised community of tribal groups and migrant labourers from states like Uttar Pradesh and Bihar. Previously, the school operated in a perilous and crumbling structure, lacking even basic facilities for its 175 students, despite the steadfast efforts of three teachers. The new, purpose-built campus now provides structurally safe and vibrant classrooms, dedicated child-friendly spaces and access to essential amenities.
This transformation is set to dramatically improve student enrolment and daily attendance by replacing a hazardous environment with one that is secure and conducive to learning. More than just infrastructure, the initiative instils a renewed sense of dignity and aspiration in both students and their families, who work primarily as daily-wage labourers, vegetable vendors and construction workers.
Executed in collaboration with the district administration and education department, this effort reflects Bridgestone India’s core mission of driving long-term social impact through strategic community partnerships. By focusing on critical gaps in educational infrastructure for displaced and underserved populations, the company fosters an environment where children can truly thrive and communities can build a more hopeful future.
