Plastic Extrusion
Plastic Extrusion: The Same Cross Section, Meter After Meter
Profiles, tubes, pipes, insulation strips and seals: your constant-cross-section products, including co-extruded profiles, produced within one chain of accountability from tooling to serial production. Cut length and packaging follow your specification.
Technical Scope
Product Groups
In extrusion, the product is sold by the meter. We work across five constant-cross-section product groups:
Extrusion profiles
Technical profiles with a constant cross section; cut to the length your specification defines.
Tubes and pipes
Straight and flexible sections for fluid transfer and protection applications.
Insulation strips
Strip sections used in thermal and acoustic insulation applications.
Seals and sealing profiles
Flexible sections that seal doors, lids and housing joints.
Co-extruded profiles
Two extruders feed a single die, combining a rigid body and a soft sealing lip in one profile. The separate seal-fitting operation disappears; with no joint line, the sealing path is continuous.
Co-extrusion is the most important word on this page: where a buyer previously combined two materials in two operations, we deliver one part in one operation.
Sectors
Application Areas
The following are typical uses for this process class; our engineering team assesses the fit of your specific part at the RFQ stage.
Home appliances
Door gaskets and sealing profiles; co-extruded sections with integrated sealing lips. Dimensional consistency matters for automated assembly lines.
HVAC
Insulation strips, drainage and duct profiles, pipe sections. Sealing performance and heat resistance lead the requirements.
Automotive
Trim and strip class sections, channel covers.
Industrial
Project-based custom sections; supplied by the meter, cut and packed to specification.
The Value Case
Dimensional Consistency and Continuity
Extrusion is a continuous process: once the cross section is set up correctly, every meter is the same meter. For the buyer this means three things:
01
Dimensional consistency
Section dimensions are verified by regular sampling against defined tolerances; every batch behaves the same on your assembly line.
02
Length flexibility
Cut length, punching and packaging follow your specification; stock and scrap burden stays on the supplier side.
03
Fewer operations
Co-extrusion pulls secondary steps such as seal fitting and bonding into the process itself. It is the line item that never shows on a price sheet but always shows in total cost.
One Chain of Accountability
Where It Sits in the Chain
Extrusion is not a standalone service here; it is one link in a single chain of accountability. Your injection molded housing (90-1100 t clamping force range), your blow molded tank and your extruded sealing profile are produced under the same roof, then joined through assembly and in-line testing and shipped as a component. Tooling is handled by the in-house mold shop (KAMAS): revisions are managed down the corridor, not between suppliers.
For a buyer with a multi-process part list, the outcome is simple: fewer suppliers, one accountable partner.
Quality
Quality Practice
Quality practice on the extrusion line is built on dimensional control: section dimensions are sampled at defined intervals and batches are recorded traceably. Our quality management system, certified to ISO 9001 and IATF 16949, covers all processes including extrusion.
