We eliminate tolerance stacking by manufacturing both metal inserts and plastic housings in-house, ensuring ±0.015mm critical tolerances across the integrated assembly. Utilizing all-electric vertical rotary machines to prevent insert shifting alongside plasma surface activation for robust mechanical adhesion, our in-house tooling fabrication ensures end-to-end control of complex sealing requirements in demanding industrial applications while mitigating supply chain risk.
High-voltage environments, relentless vibration, and strict safety regulations demand flawless metal-to-plastic integration. Whether for NEV battery busbars, aviation structural components, or precision robotic sensors, we engineer IP67/IP68-rated parts that conquer the industry’s most critical failure modes.
When outsourced metal inserts have inconsistent tolerances, micro-gaps form inside the injection mold. This causes plastic to leak (flash) onto conductive contact areas, leading to electrical shorts and rejected assemblies.
Standard inserts often lack the necessary mechanical locking strength to survive the aggressive thermal cycling and constant vibration inherent in New Energy Vehicles and heavy-duty automation.
Metal and plastic expand and contract at different rates. Without careful engineering, this “hoop stress” causes the polymer to micro-crack over time, allowing moisture ingress and causing complete component failure.
We do not rely on standard off-the-shelf hardware. Our in-house stamping and CNC turning divisions fabricate custom inserts tailored precisely to your application’s thermal, mechanical, and electrical conductivity requirements.
Copper and Phosphor Bronze
304/316 Stainless Steel
Brass and specialized aerospace-grade alloys
Metal transfers heat rapidly during the molding process. We utilize high-performance, engineering-grade thermoplastics engineered to withstand aggressive thermal shock and closely match the expansion coefficients of the embedded metals.
PEEK, PPS, and LCP
PA66+GF (Glass-filled variants)
Specialized biocompatible resins
Chemical bonding is rarely sufficient for load-bearing components. We design and stamp robust mechanical locks directly into the metal insert’s geometry to guarantee absolute structural integrity.
Precision Knurling (Diamond/Straight)
Undercuts & Through-Holes
Shut-off Flanges
Standard horizontal machines compromise precision when gravity pulls heavy metal inserts out of alignment. To meet the zero-defect requirements of the New Energy Vehicle and Robotics sectors, we invest in purpose-built vertical molding equipment and fully automated loading systems.
Gravity is the ultimate tool for placement precision. Unlike horizontal setups where metal inserts can easily dislodge before the mold closes, our specialized vertical clamping systems keep complex metal lead frames and pins perfectly seated. The integrated rotary tables allow for simultaneous insert loading and plastic injection, increasing cycle efficiency while maintaining absolute positional accuracy down to the micron level.
Human intervention introduces variability into high-precision manufacturing. We integrate advanced robotic arms for the precise loading of delicate stamped components and the safe extraction of finished molded parts. This full-scale automation ensures sub-millimeter repeatable placement, drastically lowers parts-per-million (PPM) defect rates, and guarantees stable production capacity for high-volume automotive and industrial orders.
Delivering uncompromising precision, accelerated speed-to-market, and fully integrated manufacturing solutions for the most demanding technical applications.
We compress your development cycles. By integrating agile manufacturing processes with advanced in-house capabilities, we deliver functional, test-ready components in days—helping you hit tight launch deadlines without sacrificing quality.
Quality is non-negotiable for medical, aviation, and advanced robotics applications. We achieve strict dimensional tolerances backed by comprehensive in-house metrology, including CMM vision systems, complete FAI reporting, and ISO-compliant workflows.
We don’t just execute prints; we optimize them. Our engineering team provides rigorous Design for Manufacturability (DFM) reviews upfront. By identifying potential defects early, we significantly reduce tooling risks and overall unit costs.
Grow your volume seamlessly without switching suppliers. We transition your projects from low-volume prototypes to high-yield mass production under one roof. All proprietary CAD designs are strictly protected under legally binding NDAs.
Review our documented production records across injection molding and metal component integration. Examine how we resolve complex geometric challenges and strictly control critical dimensions to ensure structural and functional reliability in demanding environments.
Eliminate unpredictable shrinkage and costly polymer warpage instantly. Our engineered Class 101 injection molds guarantee 1,000,000 continuous high-pressure shots.
Harsh automotive environments frequently compromise critical electronic component seals. Our injection overmolding provides structural durability and consistent protection.
Insert Molding involves encapsulating a pre-placed non-plastic component like brass or steel with molten resin to create a single bonded part. Overmolding typically involves molding a soft plastic resin, such as TPE, over a separate rigid plastic substrate to add grips or seals.
We mitigate cracking through rigorous DFM by optimizing plastic wall thickness and using resins with lower shrinkage rates or glass-filled reinforcements. Additionally, we pre-heat injection molding inserts to minimize thermal shock and internal stress during the cooling phase.
Yes, we are a true one-stop solution with a complete in-house high-speed metal stamping division. We manufacture custom terminals, lead frames, and contacts to ensure a perfect micron-level fit between the metal and plastic mold cavities.
By controlling both metal stamping and plastic molding in-house, we eliminate tolerance stack-up issues common in fragmented supply chains. We typically hold critical dimensions to ±0.015mm – ±0.02mm, ensuring high-performance reliability for automotive and medical applications.
To ensure high torque-out and pull-out resistance, we recommend designing inserts with diamond or straight knurling, undercuts, or grooves. For stamped parts, adding holes or bent tabs allows molten plastic to flow through and “lock” the component permanently.
We prevent flash through precision “shut-off” mold designs that create a tight seal between the mold steel and the metal insert. Our 100% CCD automated vision inspection systems further verify that all conductive areas remain clean and flash-free before shipment.
Yes, we offer bridge tooling using softer steel and manual insert loading to cost-effectively support pilot runs of 500 to 5,000 units. This allows you to validate designs and material compatibility before investing in fully automated multi-cavity hardened molds.
We adhere to IATF 16949 standards and maintain a digital thread that links every part to its specific resin batch, metal coil source, and machine parameters. This comprehensive traceability ensures risk mitigation and consistent quality for global leaders in high-demand sectors.
