FAQs
How do I choose the right rubber material for my extrusion?
Material selection depends on temperature range, chemical exposure, compression requirements, and environmental conditions. We assist in selecting EPDM, Silicone, NBR, Neoprene, FKM, or sponge grades based on real operating conditions.
Can you manufacture custom extrusion profiles?
Yes. With in-house die design and tooling, we manufacture custom profiles tailored to customer drawings or reverse-engineered samples
What tolerances can you maintain on extruded profiles?
Tolerances depend on profile geometry and material, but are tightly controlled through process monitoring and QC checks.
Do you offer spliced or fully vulcanized extruded gaskets?
Yes. Extruded profiles can be precision-cut, spliced, and compression-vulcanized to form seamless, high-strength gaskets without adhesive joints
Are sponge extrusions suitable for sealing applications?
Yes. Closed-cell sponge extrusions provide excellent compression recovery and are ideal for dust, air, and moisture sealing.
Can extrusions handle outdoor and UV exposure?
EPDM and Silicone extrusions offer excellent resistance to UV, ozone, weathering, and temperature variation.
What are typical lead times for custom extrusions?
Standard profiles are supplied quickly, while custom tooling and profiles are delivered with optimized lead times due to in-house manufacturing.
