Material Science

Engineering and Material Selection

Effective extrusion relies on proper resin chemistry and precise die tuning. We match materials to your application's operating temperature, chemical exposure, Shore hardness, and UV durability requirements.

01

Rigid PVC & ABS

Engineered for rigid structural profiles, cable trays, and framing where stiffness, high impact strength, and dimensional stability are paramount under continuous loads.

Key Properties: High modulus, flame retardant grades, clean edge retention.
02

Flexible PVC, TPE & TPU

Formulated for dynamic seals, gaskets, bumper strips, and trim requiring flexible recovery, vibration dampening, and resilience across variable operating temperatures.

Key Properties: Custom Durometer ranges, flex fatigue resistance, ozone stability.
03

Polyethylene & Polypropylene

PE and PP offer superior resistance to acids, moisture, and aggressive solvents. Excellent choice for fluid conduit, outdoor protective strips, and low-friction wear surfaces.

Key Properties: High chemical inertness, moisture barrier, lightweight density.

Multi-Material Co-Extrusion & Custom Colors

Need a rigid mounting spine fused directly with a flexible sealing lip? Our tooling supports dual-durometer co-extrusion and custom RAL/Pantone color matching directly in the melt stream.

Secondary Operations & Finishing

Raw profiles frequently demand downstream fabrication to integrate seamlessly with assembly lines. We integrate in-line and secondary post-extrusion workflows to shorten your delivery cycles.

Precision Cutting

High-speed in-line guillotine, saw, or optical rotary cut-to-length systems yielding tight length tolerances and clean burr-free ends.

Mechanical Processing

Post-extrusion stamping, slot punching, CNC milling, and precision drilling for snap fits, fasteners, and fluid drainage apertures.

Adhesive Application

Automated pre-application of acrylic foam tapes, heat-activated adhesives, or magnetic strips with protective peel liners for swift field install.

Custom Packaging

Batch packaging configured for warehouse staging, including protective sleeving, coiled spools, carton barcoding, and export wooden crating.

Design Decision Guide

When to Choose Plastic Extrusion

Extrusion represents the most cost-effective manufacturing process for parts requiring continuous lengths and uniform cross-sections. Tooling dies cost a fraction of injection molds and scale rapidly to high linear meter outputs.

Evaluating Alternate Methods?

Transitioning long components from CNC routing or continuous 3D printing to profile extrusion drastically slashes per-meter part costs and stabilizes cycle times.

Extrusion shines for window and door frames, cable guides, edge protectors, automotive door gaskets, industrial tubing, perimeter seals, and architectural wall trims with uniform longitudinal profiles.
