Why Choose Polycarbonate (PC) for Your Project?
Polycarbonate is an engineering thermoplastic engineered for applications where durability, high thermal thresholds, and optical clarity are paramount.
Impact Resistance
Significantly higher toughness than PMMA (acrylic) or ABS, making it suitable for drop-resistant housings, protective shields, and ruggedized components.
Optical Clarity
High light transmission reaching up to 89-91%, making it an ideal choice for transparent covers, optical lenses, light pipes, and display bezels.
Thermal Stability
Maintains consistent mechanical integrity across wide temperature windows (-40°C to 130°C), fitting demanding under-hood or harsh outdoor environments.
Flame Retardancy
Compatible with UL94 V-0, V-1, and 5VA ratings, critical for high-voltage consumer electronics, EV charging systems, and industrial automation enclosures.
Precision Tooling & DFM Support
Polycarbonate possesses high melt viscosity and sharp cooling characteristics. Without precise tooling design, molded parts are susceptible to sink marks, jetting, knit lines, and molded-in stress.
Our engineering team conducts an in-depth Design for Manufacturing (DFM) review for every project before cutting steel. We optimize wall transitions, draft angles, gate location, and conformal cooling circuits to ensure uniform pack pressures and minimum warpage.
Mold Tooling Steels
We build single and multi-cavity molds with hardened tool steels including P20, NAK80, and H13, ensuring dimensional repeatability and long mold life under high injection pressures.
