PPS — Injection Molding Materials

PPS is a heat- and chemical-proof engineering plastic. We mold it into tough, stable parts.

Overview

What Is PPS Injection Molding?

PPS is a heat- and chemical-proof engineering plastic. We mold it into tough, stable parts.

Material: PPS

PPS (Polyphenylene Sulfide) is a high-performance plastic. It resists heat, flames, and harsh chemicals, and molds into precise parts.

Process: Injection Molding

We melt plastic resin and inject it into a steel mold to form identical parts.

Result: Repeatable Plastic Parts

High-volume parts with consistent size and finish, made to your drawing.

Send Files & Get a Quote

Upload your 3D file and drawings. Get a quote with free DFM feedback, usually within 24 hours.

Design Review (DFM)

Our engineers check wall thickness, draft, and gates. We suggest changes that cut cost.

Mold Design & Making

We design and build the steel mold that shapes your part.

Injection & Cooling

We melt the resin and inject it into the mold, then cool and eject the part.

Inspect & Ship

We check dimensions and quality, then pack and ship worldwide.

Applications

Where PPS Is Used

Automotive

Under-hood and sensor parts.

Electrical & Connectors

Heat-proof housings.

Oil & Gas

Harsh-service fittings.

Industrial

Stable, chemical-proof parts.

Design Tips

Easy Design Tips for Beginners

New to this process? These simple rules help your part turn out well and cost less.

Keep Walls Uniform

Use a steady wall thickness so the part fills evenly and warps less.

Add Draft Angles

A small draft (1–2°) on vertical faces helps the part release from the mold.

Plan for Shrinkage

Plastics shrink as they cool. We size the mold to land on your final dimensions.

Finishes

Surface Finishes for PPS Parts

As Molded

The natural molded surface straight from the tool. Lowest cost.

Painting

A custom color coat for branding or looks.

Texturing

A matte or patterned surface for grip or style.

Clear Coat

A glossy protective layer for a premium look.
