Injectionmolding
Engineering plastic injection molding for industrial hardware components. We mold PA, POM, ABS, and PC parts with insert molding and over-molding capabilities — producing metal-plastic hybrid assemblies that go directly into our lock and latch products.
Molding Processes
Four process types
Standard Injection Molding
Single-material injection of thermoplastic parts with complex geometries, undercuts, and fine surface textures.
Insert Molding
Metal inserts (pins, bushings, threaded fasteners) are placed in the mold before injection, creating strong metal-plastic hybrid components in one step.
Over-Molding
A second plastic layer is molded over an existing part to add grip, seal, or aesthetic features. Used for soft-touch handles and gaskets.
Glass-Fiber Reinforced
Injection molding with glass-fiber filled engineering plastics (PA66+GF30) for structural parts requiring higher rigidity and heat resistance.
Materials
Engineering plastics
| Material | Grades | Properties | Applications |
|---|---|---|---|
| PA (Nylon / Polyamide) | PA6, PA66, PA66+GF | High strength, wear resistance, heat resistance, good chemical resistance | Gear mechanisms, structural clips, bearing bushings, lock internals |
| POM (Acetal / Delrin) | POM-H, POM-C | Excellent dimensional stability, low friction, fatigue resistance | Cam mechanisms, key blanks, precision gears, slider components |
| ABS | General purpose, High-impact | Good impact strength, easy to process, excellent surface finish | Handles, knobs, decorative covers, housings |
| PC (Polycarbonate) | Standard, UV-stabilized | Optical clarity, impact resistance, heat resistance up to 130C | Transparent covers, indicator windows, high-impact housings |
Typical Products
Integration Advantage
Because we also operate die casting, stamping, and CNC machining in the same facility, our injection molding department works closely with metal part production. Metal inserts are cast or machined in-house, then placed directly into injection molds — eliminating the logistics and quality risks of outsourcing.
Our in-house mold shop designs and builds injection molds alongside die casting dies, ensuring consistent tooling quality and fast turnaround for new product development. Typical mold lead time is 20-30 days depending on complexity.
This integrated approach is particularly valuable for lock and latch assemblies, where zinc die-cast bodies combine with POM cam mechanisms and PA handle grips in a single finished product.
