FAQ
Q: What specific rubber elastomers do you use for heavy-duty sleeves?
A: We compound industrial-grade NBR, EPDM, and natural rubber used in impact and abrasion environments.
Q: Can your manufacturing process accommodate custom internal geometries?
A: Yes. Our CNC-machined mold tooling supports replication of internal rib structures and specific draft angles.
Q: How do you verify structural integrity under continuous mechanical stress?
A: Every production batch undergoes cyclic compression and rotary drum abrasion testing to tracks material degradation.
Q: What is the typical lead time for initial tooling and sample approval?
A: Tooling fabrication typically 15–20 days, followed by sample validation within 5 working days.
