What materials can you use for custom rubber parts?
NBR, FKM/Viton, EPDM, Silicone, HNBR, and specialty elastomers selected for temperature, chemical exposure, and hardness needs.
Can you produce parts from a sample or drawing?
Yes. We accept physical samples, 2D PDF/DWG, 3D STEP/IGES files, or photos with dimensions, then reverse-engineer and build tooling.
What is your minimum order quantity?
Standard O-rings and seals start around 1,000 pcs; custom molded parts typically start at 500-1,000 pcs depending on size and tooling.
How do you control hardness and tolerances?
Every batch is checked against specified Shore A hardness, and dimensions are inspected with calipers, projectors, or CMM per ISO 3302 / RMA classes.
Can you provide RoHS, REACH, FDA, or PPAP documents?
Yes. We issue RoHS/REACH declarations, FDA material certificates for silicone, and PPAP packages for automotive qualification on request.
What is the typical lead time?
Tooling is usually ready in 2-4 weeks; samples ship 1 week after tool approval; mass production lead time is 3-5 weeks depending on volume.
