Glebus: Fast, reliable and customised
Glebus Alloys was established with the dawn of the new millennium. Its mission was clearly defined in the wording epitome of its founder Michael Stefanidis: “Our aim is to make manufacturing a safer place for the worker and more profitable for the company by sustaining a greener and cleaner industrial environment.”
Currently Glebus has two product lines: The first one manufactures maintenance free, self-lubricated bearings, plates and bushings under the trade name/mark of G-METAL, a material that combines graphite and bronze to form a single powder metal compound. This is the well-known, in the tyre industry, sliding (wear) plate material with their unique non-lube properties. Companies as big as Bridgestone, Michelin, Pirelli, Continental, Cooper, Hankook, Yokohama, MRF, JK Tyres, Toyo and as small as Multistrada, Petlas etc. have been benefiting from Glebus slide plates for a long time.
The company employs over 220 people in this field with over 40 years combined experience in tyre curing and mold handling. It takes pride in its fast, reliable and customised JIT services. Currently Glebus has developed products in different areas for the container shoe, top and bottom plates, axial movements and higher loads segments. An added value is its warrantee for five years that the company provides to the tyre manufacturers. Glebus factory, which is not frequent visited due to confidentiality and patent related issues, uses a modernised sintering oven with high NH Gas Processor and CNC equipment that produce slide plates custom to customers drawings and specifications.
Glebus Alloys has strengthened its position in the market by acquiring last year its supplier CERAMET SpZoo, a worldwide leading producer of sliding materials, (plates, bushings and bearings). This development provided the company new market possibilities in different industries such as power engineering, steel, hydro and solar energy, etc.
Additionally, recently Glebus Alloys bought a stake into a specialised injection molding plastics production company RGP based in Czech Republic. RGP is focused in specific industries and high-end precision thermoplastic projects.
Glebus Alloys is the only worldwide patent holder for the new tyre mold venting systems under the brand name Glebus Spring Vents.
Glebus Spring vent technology, which was started to be commercialised in 2009-2010, has created mountainous waves in the rubber compound and curing world. Their unique demountable, three-piece design provides a lot of flexibility that older spring vents, the one-piece type is not able to match in anyway. Glebus Alloys has created a complete new technology and support system based in this patented product. The company starts by evaluating the current situation and status of the tyre curing environment and we find solutions how you can develop a manufacturing place with free spew tyres, greener and less expensive by item cost. Glebus Spring vents may replace existing vents (microvents-minivents) in the same hole and there is need for expensive vacuum containers or press piping or injection type segmented molds.
Glebus Spring Vents is the only “free commercial market” demountable design of Spring Vent, that improves the tire appearance, decreases the down time and lower the maintenance cost.
This second product line employs 20 people with over 100 years combined experience in rubber compounding, mold design, mold manufacturing, mold cleaning and tire curing.
Glebus Alloys is proud to present the latest development of the G5 type spring vent. This production technology incorporates tighter tolerances. This unique patented product can be found in three diameters 2.5mm, 3.00mm and 3.2mm for the tread and shoulder area as well as in sidewall. The ability to have a stem movement from 0.15mm to 0.5mm allows the spring vents to be used in summer and winter compounds.
