Material Database
Polycarbonate (PC)
Polycarbonate (PC) is one of the common materials in engineering plastics that balances strength and toughness, making it suitable for creating appearance prototypes, electrical insulation components, and functional verification parts in CNC machining. If you want a cleaner look with transparent edges, you can choose polished (transparent edges); If you care more about silkscreen marking or uniform surface texture, you can also combine spray painting or silkscreen printing.

Order Recommendation: If there are key dimensions/mating surfaces/assembly holes, please provide STEP + 2D (PDF/DWG/DXF) markings; If you want a more "finished product" appearance (spray painting/silk screen/transparent edge polishing), please clearly state the appearance surface, target texture, and acceptable mark standards in the remarks. We will first conduct DFM before confirming the processing and post-treatment plan.

More suitable (recommended)
Appearance prototype: Samples that can be polished/spray-painted, and capable of silk screen/laser engraving marking; Electrical insulation structural components: brackets, housings, fasteners, etc., focusing on assembly and dimensional consistency; Functional verification: Requires rapid processing and small-batch verification of structure and assembly relationships
Not recommended for direct use (suggest changing materials/processes)
Long-term use at extreme high temperatures: Please evaluate the more temperature-resistant material system based on working conditions; High-wear sliding surfaces: It is recommended to evaluate wear-resistant materials or add surface solutions; Highly corrosive environments: It is recommended to choose materials that better match the medium
