The Plastic Extrusion Process

Crosshead extrusion coating applies a polymer layer around a pre-existing core as it passes through an extrusion head. The core and molten polymer ent

Thermoplastics soften when heated and solidify when cooled. Conventional thermosets form a permanent crosslinked network during curing and cannot subs

A ULTEM datasheet can show 217°C, 201°C, 190°C and 170°C for the same resin. Each number answers a different question. If an engineer

An ABS profile can meet its cross-sectional dimensions and still fail to fit along its length. It may bow, curve sideways or twist after it leaves the

A custom flat ABS plastic strip is not fully specified by width, thickness, and color. If it must fit a channel, align with another component, or rema

ABS is one of those materials that looks simple until a project moves from an early drawing into actual production. It is familiar, widely available a

An ABS profile that passes dimensional inspection can still fail in service, and the reasons are usually decided at three points on the line: how dry

Short answer: The PVC extrusion process runs from dry blend through twin-screw plastication, vacuum venting, the die, calibration and haul-off. Geomet

The wrong polymer rarely fails on the line. It fails in the field Most guides on extrusion material selection read like a parts catalog: PVC is cheap,

If you are weighing plastic extrusion vs injection molding for a component that hasn't been tooled yet, the decision is usually smaller than it feels.

The average North American vehicle now contains over 400 pounds of plastics and polymer composites, up 16% from a decade ago (American Chemistry Counc

A Rapra Technology survey found that polycarbonate accounts for roughly 1% of global resin consumption by weight, yet contributes 10–15% of docu
