Your Partner in Precision Tooling & Agile Manufacturing.

To ensure strict dimensional compliance for critical EV connector components and complex injection mold inserts, our quality control laboratory utilizes the Swiss-engineered TRIMOS V Plus height gauge. Deployed on a high-precision granite surface plate to establish a reliable zero reference, this advanced instrument delivers highly repeatable 1D and 2D vertical measurements. Its robust air-bearing system and high-resolution optical scale allow our metrology team to rapidly verify step heights, hole centers, and structural geometries, guaranteeing that manufactured lots meet rigorous tolerance requirements before shipment.

Engineered for the high-yield production of cylindrical components, our centerless grinding machines deliver exceptional diametrical consistency for critical EV connector pins, micro-shafts, and tooling ejector pins. By utilizing a continuous through-feed process between the grinding and regulating wheels, this equipment completely eliminates the need for spindle centering. This method ensures tight concentricity and rapid cycle times, making it a highly efficient solution for processing large batches of micro-cylindrical parts while maintaining stringent geometric tolerances.

For oversized progressive stamping dies and massive EV mold bases, standard surface grinders simply cannot bridge the required dimensions without structural deflection. Our heavy-duty Gantry Surface Grinder utilizes a massive double-column architecture to maintain absolute rigidity across extremely wide work envelopes. This ensures that even our largest, multi-station tooling plates achieve perfect planarity and parallelism. By eliminating geometric variance on foundational mold bases, we guarantee the strict alignment required for high-speed, high-tonnage stamping operations.

To guarantee the absolute reliability of critical EV connectors and sensor housings operating in harsh environments, we employ advanced pressure decay leak testing across our assembly lines. Custom-engineered pneumatic fixtures securely seal the hybrid metal-plastic components, while high-sensitivity pressure sensors detect microscopic leaks that visual inspections cannot identify. This non-destructive, quantitative testing method ensures every shipped component strictly complies with IP67/IP68 waterproof and dustproof standards, completely eliminating the risk of field failures due to moisture ingress.

Operating within a strict climate-controlled environment, our Seibu low-speed wire Electrical Discharge Machining (EDM) systems are engineered for the extreme tolerances required in modern tooling. By utilizing multi-pass cutting techniques and advanced corner-control algorithms, these machines achieve sub-micron pitch accuracy and near-mirror surface finishes without inducing mechanical stress on the workpiece. This capability is critical for fabricating high-precision progressive stamping dies, intricate connector mold inserts, and tight-tolerance extrusion profiles, ensuring absolute die clearance consistency and extended tooling life.

Configured specifically for high-volume production of critical electrical contacts and EV terminal components, our Zhenli high-speed stamping presses operate at exceptional strokes-per-minute (SPM) rates. These presses are integrated with automated coil feeding systems to drive complex progressive dies, transforming copper alloys and specialty metals into finished, high-precision terminals in a single continuous operation. By maintaining strict dynamic balance and ram alignment at high speeds, we eliminate burrs and ensure absolute dimensional consistency across millions of cycles, significantly lowering the per-part cost for high-volume automotive and electronics applications.

When it comes to manufacturing large-scale progressive stamping dies and heavy-duty EV injection molds, absolute structural rigidity is non-negotiable. The Guanchi GC-2518L features a massive double-column gantry architecture designed to handle oversized tooling blocks and perform aggressive heavy stock removal without geometric deflection. By utilizing this heavy-duty machining center, we efficiently process massive mold bases and structural components in-house. This capability ensures that even our largest tooling projects maintain strict parallelism and dimensional accuracy from the very first roughing cycle to the final finishing pass.

Unlike conventional horizontal setups, our vertical injection molding machines utilize a top-down clamping mechanism. This gravity-assisted orientation securely holds delicate metal inserts, lead frames, and copper busbars in precise alignment before the polymer is injected. It provides a highly effective manufacturing solution for complex insert molding and overmolding processes across diverse industries. By preventing insert displacement during high-pressure injection, this system ensures absolute structural integrity and positional accuracy for critical components, ranging from heavy-duty EV connectors to intricate hybrid metal-plastic assemblies.

In high-volume progressive stamping for EV terminals, micro-punch wear is inevitable. Our dedicated row of precision terminal grinders forms the backbone of our agile in-house toolroom. These specialized benchtop grinders allow our tooling engineers to perform rapid, micron-level regrinding and custom shaping of carbide punches, die inserts, and ejector pins. By maintaining these tooling components in-house rather than outsourcing, we drastically reduce machine downtime, ensuring uninterrupted, high-yield production of precision connector terminals.

Our precision ultrasonic welding systems provide advanced, adhesive-free assembly solutions for critical EV components requiring absolute hermetic sealing. Utilizing high-frequency acoustic vibrations, these machines create solid-state molecular bonds between thermoplastic parts in milliseconds. This process eliminates the outgassing risks associated with glues, ensuring the internal integrity of sensitive electronic housings and multi-part high-voltage connectors. The system delivers highly repeatable, stress-free welds essential for components subjected to harsh under-hood automotive environments.
