Custom Injection Molding Services
Custom Injection Molding Services for OEM Plastic Parts
FSD Precision provides custom plastic injection molding services in China, supporting mold manufacturing, engineering review, material selection, injection molding production, inspection, secondary operations and export-ready delivery.
What is Injection Molding?
Injection molding is a manufacturing process used to produce repeatable plastic parts by injecting molten plastic material into a mold cavity. It is commonly used for OEM components that require stable dimensions, functional surfaces, consistent quality and medium to high-volume production.
Injection Molding Capabilities
FSD supports custom injection molding projects from material selection and mold manufacturing review to molding production, secondary operations, inspection and export-ready delivery.
Plastic Injection Molding
For custom plastic housings, covers, brackets, connectors and functional components.
Mold Manufacturing Support
In-house mold manufacturing support for prototype molds and production molds.
Insert Molding When Required
