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.

Nokian Tyres gathered nearly 100 workshop representatives from five partner companies at the Hakka Ring, its year-round testing facility in Santa Cruz de la Zarza, Spain, to highlight its latest advances in all-season tyre technology and exchange views on market trends and industry challenges. The company said the test center, designed for all-weather performance evaluation, reflects its focus on safety, performance and sustainability throughout the year.

During the event, Iberia Country Manager Luis Miguel Cabanas presented brand updates, new product developments and future strategic direction. Partners were given the opportunity to drive the Seasonproof 2, the company’s newest all-season flagship tyre. Manufactured at Nokian Tyres’ zero carbon emissions factory in Romania, the Seasonproof 2 has been independently tested and verified by TUV SUD, Tyre Reviews and WhatTyre, and utilises up to 38 percent renewable, recyclable and ISCC PLUS–certified materials.

The tyre features the company’s latest innovations aimed at improving traction, precision and efficiency in varying conditions including technology designed to balance summer handling with winter grip, adaptive tread design for better performance in changing weather and a new compound optimised for durability, wet grip and fuel economy.

The event culminated with high-speed test runs on the 7-kilometre oval circuit with 40-degree banked corners, providing what the company described as an impressive demonstration of speed, control and overall driving performance. Nokian Tyres said the showcase strengthened relationships with key partners and reinforced its commitment to leading sustainable innovation in the all-season segment.

Hankook Tire and Technology reported consolidated revenue of KRW 5.4127 trillion and operating profit of KRW 585.9 billion for the third quarter of 2025, the company said in a statement.

Tyre business sales rose 11.2 percent year-over-year to KRW 2.7070 trillion, while operating profit climbed 10.4 percent to KRW 519.2 billion, marking the company’s highest-ever quarterly performance.

Hankook attributed growth to stronger demand across global replacement and OE markets and a rising mix of high-inch tyres. Lower raw material and logistics costs helped cushion the impact of US automotive parts tariffs.

Hanon Systems, which has been fully consolidated into Hankook Tire’s results since the first quarter, generated KRW 2.7057 trillion in revenue, up 8.2 percent from a year earlier. Operating profit reached KRW 95.3 billion, an increase of 1.7 percent year-over-year and 48.2 percent quarter-over-quarter.

High-inch (18 inches and above) passenger car and light truck tyres accounted for 47.4 percent of segment sales in the quarter, up 2.6 percentage points from a year earlier. EV tyre sales represented 27 percent of the total, a 7-point increase year-over-year.

Hankook continued expanding OE fitments for premium EVs, citing supply agreements for the Porsche Macan, Xiaomi YU7, BMW iX, New i4 and New X3. The company now equips about 50 global automotive brands across more than 290 models.

Hankook’s EV-focused iON line-up and Ventus performance range won EV Tire of the Year and Performance Tire of the Year at the UK-based WhatTyre Awards, reinforcing its technology leadership.
