Questions
What buyers ask first
Which grade do I start from?
Send the medium, the service temperature and the hardness you need — EPDM, NBR, FKM and silicone cover −60 to +200 °C.
What tolerance can you hold?
ISO 2768-m on moulded and extruded parts, ±0.05 mm on critical features, ISO 3302-1 class M2 on rubber.
Who owns the tooling?
You do, after the first production order. Tooling is quoted separately and is not amortised into the part price.
How fast is a quote or a sample?
Quotation within 24 h on a dimensioned drawing, DFM report in 3–5 working days, T1 samples in 20–25.
