Plastic Injection Molding Materials & Resin Selection on PlasticMolder — Plastic Injection Molding Manufacturer China

ABS Injection Molding

ABS Injection Molding at Production Scale

ABS injection molding is the default for anything that has to look good and survive handling. Enclosures, trims, and consumer shells rely on ABS because it paints, textures, and plates cleanly while staying rigid and impact-resistant.

The work in an ABS program is cosmetic control. Gate placement, venting, and pack pressure decide whether a surface is flawless or covered in sink marks and flow lines. We design the tool and process around the visible face.

Nylon (PA6 / PA66) Injection Molding

Nylon (PA6 / PA66) Injection Molding at Production Scale

Nylon injection molding covers the workhorse engineering plastics behind most gears, bushings, and structural clips. PA6 and PA66 give teams a rare combination of toughness, fatigue resistance, and low cost that few materials match.

The catch with nylon is moisture. It absorbs water from the air, which changes dimensions and properties after molding. A sound program controls drying, regrind, and conditioning so the part that ships matches the part that was qualified.

PEEK Injection Molding

PEEK Injection Molding at Production Scale

PEEK injection molding is the right choice when a part must survive heat, chemicals, and repeated sterilization that commodity plastics cannot. For engineering and procurement teams, the decision is rarely about cost per gram and almost always about total function in a hostile environment.

A dependable PEEK program is built on drying discipline, tight melt-temperature control, and tooling that resists wear from a high-melt-point resin. Get those three right and the parts are consistent; skip any one and you see splay, weak welds, or dimensional drift.

Polycarbonate (PC) Injection Molding

Polycarbonate (PC) Injection Molding at Production Scale

Polycarbonate injection molding is the answer when a part must be clear, tough, and heat-resistant at once. Lenses, light pipes, and transparent housings lean on PC because almost nothing else matches its impact strength and clarity.

PC is unforgiving on process. It must be bone dry, gated gently, and filled at the right speed or it stress-whitens and turns brittle. The difference between a good optical part and a scrap one is entirely in drying and fill control.

Polypropylene (PP) Injection Molding

Polypropylene (PP) Injection Molding at Production Scale

Polypropylene injection molding is the low-cost, high-volume workhorse for caps, containers, and anything with a living hinge. PP resists chemicals, shrugs off fatigue, and molds fast, which keeps part cost down.

The one thing PP demands is shrinkage awareness. Its molded shrinkage is higher than most resins, so the tool must be cut to suit. Get that wrong and every part is undersized; get it right and PP runs almost forever.

TPU Injection Molding

TPU Injection Molding at Production Scale

TPU injection molding puts elastomeric feel where the user actually touches. Grips, seals, and wheels rely on TPU because it flexes, resists abrasion, and survives oils that would destroy softer rubbers.

TPU behaves like a flexible solid, not a free-flowing resin, so fill and packing need care. Too cold and it shorts; too hot and it degrades. The process window is narrower than for rigid plastics, and we lock it on validation.
