Technical parts in rubber and silicone for the rail industry
CHEVALIER CLERET ELTEC designs and manufactures technical rubber and silicone moulded parts for the rail industry. Our solutions are designed for the constrained environments of rolling stock and infrastructure, where reliability, durability and resistance to extreme conditions are essential.
Railway elastomer injection and moulding expertise
We have expertise in rubber injection, LSR silicone injection, elastomer moulding and overmoulding of inserts (metal, plastic). These technologies enable us to produce robust, precise and durable railway parts that meet industry standards.
For this type of application (rail), we mainly use compounds that comply with NF F16-101/ NF F16-102 standards, and compounds injected are as follows:
- NBR, HNBR, FKM / VITON: for specific sealing applications and resistance to fuels or oils
- EPDM: excellent resistance to UV, ozone, heat and atmospheric agents
- CR (Chloroprene): good compromise between mechanical resistance and fire behaviour
- Silicone (LSR or HCR): temperature resistance, high elongation
Functions performed by our railway parts
Our rubber and silicone parts, or metal-rubber versions, are integrated into systems that provide..:
Production adapted to the constraints of the railway sector
Our production units in France and Romania ensure customized manufacture in small, medium or large series, from a few dozen to several hundred thousand parts per year.
- Semi-automatic or fully automatic processes
- Material traceability, rigorous quality monitoring
- Documentation supplied according to customer requirements: REACH, RoHS, TDS, test reports, inspection plans, etc.
