The profile or the gap it fills
A drawing of the section, or the housing it has to seal, with the closing direction.
Continuous sections · profiles and tube
Silicone extrusion.
Some parts aren't moulded at all. Door seals, cord, tube and edge trims are pushed through a die and cured continuously. We supply extruded sections, cut them, join them and pair them with your moulded parts.
How we handle extrusion
One supplier for the moulded part and the seal that goes round it.
Extrusion is a different kind of line from moulding. It runs continuously, needs a die for every profile, and makes sense at the scale of kilometres rather than pieces. We don't pretend to run that line in Bidford-on-Avon.
What we do is manage extruded sections as part of your programme. We specify the profile with you, place the extrusion with a trusted partner, then cut, join, bond and inspect the sections here alongside the moulded parts that sit next to them.
That matters when a product needs both — a moulded gasket with an extruded perimeter seal, say, or a housing with a moulded corner and extruded straight runs. One paper trail, one set of colour references, one point of contact.
We're open about which operations happen where. The extrusion line is a partner's; the finishing, joining, inspection and packing are ours.
What we supply
Three families of extruded section.
Solid and sponge profiles
D-sections, P-sections, bulb seals and custom shapes for doors, lids and enclosures. Solid for durability, sponge for low closing force.
Cord, tube and strip
Round cord for spliced O-rings, tube for fluid handling and sleeving, flat strip for cushioning and gasketing.
Joined frames
Straight runs joined into closed frames with moulded or bonded corners, so the seal arrives as one piece ready to fit.
How a profile programme runs
From sketch to fitted seal.
The profile design is where most of the performance is decided, so that's where we spend the time.
Profile design
We look at closing force, compression range and how the seal is retained. A small change in wall section makes a big change in feel.
Die and first samples
The partner line cuts the die and runs first samples. We check them here against your housing.
Cutting and joining
Sections are cut to length, spliced or corner-moulded into frames, and checked for joint strength.
Inspection and packing
Profiles and frames are inspected and packed with the batch record, alongside any moulded parts in the same order.
To quote it
What we need to know.
Solid or sponge
If you're not sure, tell us the closing force you can afford and we'll suggest one.
How it's supplied
Coils, cut lengths or joined frames — each changes the finishing work.
Annual metres or pieces
Extrusion economics are set by length run, so an honest annual figure matters.
