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.

HS HYOSUNG ADVANCED MATERIALS was honoured at the sixth Endangered Species Day ceremony, which took place on 1 April 2026 at the Chollipo Arboretum in Taean. The company received a certificate recognising its sponsorship of endangered species conservation. This annual event, organised by the National Institute of Ecology, has been running since 2021 with the goal of increasing public awareness about the protection of threatened species. The institute also runs a special recognition programme that celebrates corporate contributions to conservation efforts.

Since signing an agreement with the National Institute of Ecology in 2022, HS HYOSUNG ADVANCED MATERIALS has been acknowledged for its ongoing commitment to preserving biodiversity. The firm planted 2,000 specimens of Veronica pusanensis, a Class II endangered wild plant and has been listed as an official conservation sponsor since 2023. The company has also focused on safeguarding essential pollinators like bees. In 2023, it created a pollinator garden at the Mulbeodeul Ecological Experience Learning Center in Seocheon, followed by another in 2024 at the Ulsan Climate Crisis Response Education Center, where nectar rich plants such as canola and buckwheat help sustain bee populations and reproduction.

Additionally, the company tackles threats to biodiversity through regular removal of invasive species. Since 2023, it has annually cleared harmful plants including Sicyos angulatus and Humulus japonicus from Yubu Island in Seocheon, a UNESCO World Natural Heritage site. These persistent efforts demonstrate a holistic approach to protecting both flora and fauna, from endangered wild plants to critical pollinators, while also managing ecological threats to preserve natural heritage areas.

An ESG official from HS HYOSUNG ADVANCED MATERIALS said, “We are honoured to receive this recognition for our efforts in endangered species conservation. We will continue to work closely with the National Institute of Ecology to further expand and strengthen our conservation initiatives.”

Kumho Tire USA has renewed its commitment to Formula DRIFT by extending its sponsorship for another three years. For the 2026 Formula DRIFT PRO Championship, the company has assembled a formidable roster of six elite drivers to represent Team KUMHO. This group includes Jeff Jones, Andy Hateley, Rome Charpentier, Jack Shanahan, Ryan Litteral and Cody Buchanan. Each of them will compete on KUMHO Ecsta V730 tyres, a model specifically developed to withstand the punishing conditions of high level competitive drifting.

Jeff Jones returns for his third season with KUMHO and his 18th in the PRO Championship, more determined than ever to reach the podium and build on his legacy as a drifting pioneer.

Rome Charpentier, a Southern California native who began chasing his racing dreams at age 30, has achieved multiple podium finishes worldwide and is starting his second year with KUMHO.

Jack Shanahan, who earned Formula DRIFT PRO 2025 Rookie of the Year on KUMHO tyres, now aims for the championship podium in 2026. Hailing from Ireland, he started racing at 10 and has won multiple international titles in hot rod racing, tarmac rallying and drifting.

Having partnered with teams in a thoughtful and strategic way, its effort drives a powerful narrative throughout the season. And KUMHO tyres appear both competitive and reliable, allowing the teams to push hard on the track against top products from their main rivals.
