ISO 9001 Certified Insert Molding Service with 300,000 – 800,000 Shots Mold Life

KDET specializes in insert molding services that combine metal components with thermoplastic materials to create integrated, high-strength assemblies in a single manufacturing step. Our insert molding capabilities cover threaded brass inserts, steel bushings, electrical contacts, custom metal stampings, and machined components — all precisely positioned within the mold cavity and encapsulated with engineering-grade thermoplastics. Since 2007, we have produced millions of insert-molded components for automotive, electronics, industrial equipment, and consumer product applications.

KDET provides world-class insert molding solutions engineered for the demanding requirements of global OEM manufacturers. With 18 years of industry experience and a fully integrated manufacturing facility in Xiamen, China, we deliver end-to-end solutions from engineering consultation and DFM analysis through mold manufacturing, production, quality assurance, and global logistics. Our structured project management approach ensures clear milestones, transparent communication, and documented quality at every stage.

• Precision Insert Placement: Our molds feature precisely machined insert pockets with tolerances of ±0.02mm, ensuring consistent insert positioning within the finished part. Automated and manual loading options accommodate production volumes from prototype to millions annually.
• Threaded Insert Expertise: We stock standard brass threaded inserts (M2 through M12) and can accommodate custom inserts per your specifications. Insert retention strength is validated through pull-out and torque testing per project requirements.
• Multi-Insert Capability: A single molded part can incorporate multiple inserts of different types, sizes, and materials — for example, combining brass threaded inserts, steel locating pins, and copper electrical contacts within one molded component.
• Insert Pre-Heating: For applications requiring enhanced plastic-to-metal adhesion, we offer insert pre-heating systems that bring metal inserts to optimal bonding temperature immediately before mold placement, reducing thermal shock and improving bond strength.
• Automated Insert Loading: For high-volume production exceeding 100,000 pieces annually, we implement robotic insert loading systems with vision verification to ensure 100% insert presence and orientation before each molding cycle.
• Insert Design Support: Our engineering team provides insert design recommendations including knurling patterns, undercut geometry, and surface treatments that optimize mechanical interlocking between the metal insert and plastic matrix.

• Automotive: Sensor brackets with threaded mounting inserts, engine cover attachment points with brass threads, wiring harness clips with metal retention springs, and pedal assemblies with steel bushing inserts.
• Electronics: PCB mounting bosses with threaded brass inserts, connector housings with embedded contacts, battery compartment terminals, and heat sink mounting brackets with thermal interface inserts.
• Industrial Equipment: Pump housings with threaded pipe connections, valve bodies with metal seat inserts, conveyor components with bearing inserts, and machinery guard panels with threaded mounting points.
• Consumer Products: Appliance housings with threaded assembly inserts, furniture connector blocks with metal threads, power tool bodies with bearing seat inserts, and sports equipment with metal reinforcement inserts.
• Electrical: Circuit breaker housings with embedded bus bars, switch bodies with contact inserts, terminal blocks with brass connectors, and junction box mounting plates with threaded earth points.
