Injection Molding Services from PCBasic
PCBasic delivers precision injection molding with advanced automation and Class 10,000 cleanrooms. From mold development to assembly, we provide
full-process solutions. Certified to ISO 9001, ISO 13485, and IATF 16949, we serve automotive, medical, and electronics industries.
Injection Molding
Single-color injection molding uses one material in a single process. With precise mold machining, we achieve 0.02mm tolerance and offer free mold flow analysis. Ideal for mass production.
Dual-Color / Multi-Color Molding
Dual-color: Different areas of a product feature different colors (e.g. phone keypads). Multi-color: Special screws create color gradients (e.g. rainbow toy effects)
Insert Molding
Plastic is molded around inserts, combining materials in one part. Common in electronics, automotive, and medical fields for compact, high-performance, and cost-effective products.
Extrusion Molding
Extrusion molding melts raw materials and extrudes them through a die to form the desired profile, followed by cooling and shaping into final products. It offers fast production speed, high efficiency, and low cost.
