Custom Plastic Parts Built for Industrial Equipment
Industrial equipment requires components that withstand mechanical stress, thermal fluctuations, and chemical exposure. PPMolding provides custom injection molding solutions for manufacturers, automation engineers, and equipment OEMs that need reliable, production-ready plastic parts.
From DFM analysis through volume production, we manage the manufacturing cycle around the functional requirements of your machinery.

Engineering support
Function-first design review for demanding assemblies
Industrial plastic parts often function as more than enclosures. They are integrated into high-stress assemblies where dimensional accuracy directly affects mechanical performance.
Our engineering team reviews your 3D models for industrial functionality, analyzing wall thickness, draft angles, rib structures, and gate locations. This helps prevent sink marks, warping, and internal voids before mold construction begins, reducing re-tooling risk and supporting consistent field performance.
DFM analysis
Review geometry and molding risks before tooling investment.
Production readiness
Develop repeatable processes for stable, long-term supply.
Material selection
Industrial plastic parts: material and performance specifications
Selecting the right resin is critical for parts exposed to mechanical loads, friction, heat, chemicals, or impact. The following materials support a range of industrial equipment requirements.
| Material | Load / stress requirements | Typical part type | Industrial application |
|---|---|---|---|
| POM (Acetal) | High stiffness, low friction | Gears, bearings, bushings | Robotics and automation |
| PA66 + 30% GF | High structural strength, impact resistance | Structural brackets, housings | Industrial machinery |
| PEEK | High heat, chemical, and wear resistance | Technical seals, valve components | Chemical processing |
| ABS | Moderate impact, good aesthetics | Control panels, outer enclosures | Electronic equipment |
| PC/ABS | High impact, rigidity | Safety guards, equipment covers | Heavy-duty equipment |
| PPS | Extreme thermal stability | Electrical connectors, pump parts | Energy and industrial systems |
Manufacturing capabilities
Functional parts, produced for repeatable performance
Our injection molding capacity supports small precision gears through large equipment housings.
Tight tolerance molding
±0.05 mmCritical dimensions are controlled so mechanical parts fit securely within your assemblies.
Insert molding
Mold directly over metal threaded inserts, terminals, or pins for robust connections that withstand vibration and repeated assembly.
Overmolding
Add TPE or TPU over rigid substrates for vibration damping, improved grip, and fewer secondary assembly steps.
Technical surface finishing
Choose matte, textured, or polished finishes to meet friction, handling, or user-facing equipment requirements.
Production workflow
A controlled path from CAD files to stable production
We focus on moving projects efficiently from design to production without sacrificing quality.
