PC Plastic Injection Molding Services
Precision injection molding for polycarbonate components. We produce clear, high-impact, and heat-resistant parts for lighting, consumer electronics, and medical device housings where optical clarity and structural integrity are non-negotiable.
Why Polycarbonate
An Engineering Thermoplastic That Performs Under Pressure
Polycarbonate is the preferred material for components that must withstand physical stress while maintaining a precise appearance. It outperforms standard resins in clarity, toughness, and thermal stability.
Optical Transparency
Up to 90% light transmission with clarity suitable for lenses and light guides.
High Impact Strength
Virtually unbreakable in many applications, ideal for safety and protective gear.
Heat Resistance
Heat deflection from 125°C to 140°C depending on grade selection.
Dimensional Stability
Low shrinkage and high tolerance capability for precision assemblies.

Precision Molding
Engineered Process Control for Demanding Polycarbonate
Manufacturing with polycarbonate requires strict adherence to process parameters. Because PC is hygroscopic, we deploy professional drying systems to prevent moisture-related defects like silver streaks or brittleness.
Optical Quality Management
We control mold surface finishes from SPI A-1 mirror polish to textured surfaces, ensuring desired light diffusion or clarity.
Tolerance Control ±0.05 mm
Snap-fits and assembly interfaces function correctly upon delivery, with dimensional verification on every batch.
Stress Management
Engineering optimizes gate location and cooling cycles to minimize residual stress, preventing warping or stress cracking.
Equipment Range 50 – 1,000 Tons
From small intricate optical lenses to large structural equipment covers, our press capacity scales with your part geometry.

Design Support
Engineering Support for Design for Manufacturing
Successful production starts with DFM. Polycarbonate has specific flow characteristics that influence wall thickness and draft angles. We review your 3D models (STEP, STP, X_T) to identify potential issues before tooling begins.
Our DFM review is included at no additional cost with every quoted project, helping you reduce tooling iterations and accelerate time to market.
Our DFM Review Covers
Wall Thickness Optimization
Ensuring uniform thickness to prevent sink marks and internal stress.
Draft Angle Calculation
Calculating sufficient taper for smooth part ejection without damaging the high-gloss surface.
Ribs and Bosses Positioning
Positioning structural reinforcements to maintain strength without causing surface blemishes.
Gate Location Strategy
Identifying optimal gate placement to balance flow, weld line control, and cosmetic appearance.
