Injection Molding Materials

PartsMake helps engineers select, mold, finish, and inspect plastic components using materials matched to performance, appearance, tolerances, and production requirements.

Material decisions

01

Performance first

Balance strength, flexibility, heat resistance, wear, and chemical exposure.

02

Process-aware selection

Account for mold design, wall thickness, shrinkage, and surface expectations.

03

Production confidence

Move from engineering samples to repeat production with controlled quality.

A practical material guide

Choose a polymer with the complete part in mind

Injection molding material selection affects part performance, tooling strategy, cycle time, appearance, and long-term reliability. PartsMake reviews the application and manufacturing details before production, helping connect the right engineering-grade thermoplastic to the actual needs of the component.

Explore the material topics below for guidance on common options such as ABS, PC, PC-ABS, PP, POM, Nylon, PBT, and TPU.

How we approach material selection

From material question to production-ready part

Each project is reviewed as a combination of material, geometry, process, quantity, and intended use.

1

Application review

Start with what the part must do

Review operating loads, temperature, moisture, chemicals, wear, impact, electrical needs, appearance, and assembly conditions.

2

Design for manufacturing

Connect the resin to the geometry

Wall thickness, draft, ribs, bosses, shrinkage, warpage risk, gate locations, and tooling constraints all influence the final choice.

3

Production planning

Prepare for the required volume

Prototype, pilot, low-volume, and repeat production may call for different tooling, process, finishing, and inspection considerations.

4

Quality and finishing

Verify the result beyond molding

Inspection, color and texture expectations, secondary processing, assembly, and packaging are considered as part of the finished component.
