Selection & Fitting Notes
- Extruded profiles hold cross-section far more consistently than cut length. Tell us which one your assembly actually depends on.
- A solid profile has very little collapse space: design the housing to stop compression rather than relying on the rubber to bottom out, or closing force climbs steeply.
- For closed frames, decide up front between mitred-and-bonded corners and continuously moulded corners - they behave differently at the seam.
- Self-adhesive backing needs a clean, dry, degreased surface. On powder coating or low-energy plastics, test adhesion on a sample before committing.
Frequently Asked Questions
What is the lead time for Triangular Groove Silicone Strip?
Stock profiles of this type are held in inventory and can ship immediately. Custom extrusions of Triangular Groove Silicone Strip take 2-4 weeks, including tooling and production. Expedited service is available if you need the parts sooner.
Can I get samples of Triangular Groove Silicone Strip before placing a full order?
Yes. We can send prototype samples or run a small trial batch of Triangular Groove Silicone Strip so you can test fit, compression set and performance before committing to a production order. Sample policy and freight terms are confirmed together with your quotation.
Do you make the tooling for Triangular Groove Silicone Strip in-house?
Yes. We build our own extrusion dies and tooling in-house, which shortens lead times for custom triangular groove silicone strip and keeps dimensional accuracy and batch-to-batch repeatability under tighter control.
What tolerance should I expect on Triangular Groove Silicone Strip?
Extrusion holds the cross-section more consistently than the cut length. Tell us which dimension your assembly actually seats on and we will tolerance to that. Send the drawing with the critical dimension marked and we will quote against it.
Can Triangular Groove Silicone Strip be supplied with adhesive backing or joined into a frame?
Both are possible. Self-adhesive backing needs a clean, dry, degreased surface - on powder coating or low-energy plastics, test it on a sample first. For continuous frames we can mitre and bond the corners or discuss moulded corners, depending on how the seam has to perform.
How much should I compress Triangular Groove Silicone Strip in the housing?
Design the housing to stop the compression rather than letting the rubber bottom out. A solid profile has almost no collapse space, so squeezing it fully makes closing force climb steeply and makes the door or cover hard to shut. A drawing of the joint lets us suggest a workable compression.
