Injection Molding Material Selector

Select your application, design priority, and environment to get a first-pass material recommendation for injection-molded plastic parts.

1. Application Type

Enclosure / HousingGeneral plastic covers, cases, and product housings.

Snap-fit ComponentParts that flex during assembly.

Structural PartParts requiring stiffness and load support.

Gear / Moving PartSliding, wear, friction, or mechanical movement.

Transparent PartClear lenses, covers, windows, or light pipes.

Cosmetic PartAppearance-driven external product surfaces.

2. Primary Requirement

Low CostCost-sensitive production parts.

Impact ResistanceParts that may be dropped or knocked.

FlexibilityParts that need to bend or deflect.

Heat ResistanceParts exposed to elevated temperatures.

Wear ResistanceMoving, sliding, or low-friction parts.

Appearance QualityVisible parts with cosmetic requirements.

3. Environment

IndoorNormal indoor product environment.

Outdoor / UVSunlight or weather exposure.

High TemperatureHeat exposure or warm operating conditions.

Chemical ExposureCleaning agents, oils, or chemicals.

Moisture / HumidityHumid or wet environments.

Repeated FlexingParts that flex multiple times.

4. Production Priority

Cost OptimizedKeep material and production cost low.

BalancedGood balance between cost and performance.

Performance DrivenMaterial performance matters more than lowest cost.

This is a first-pass material screening tool for injection molding. Final material selection should consider exact grade, supplier data, tooling constraints, certifications, testing, and production environment.
