Description

Feature

● Vertical Clamp & Vertical Injection Architecture: Gravity holds pre-placed wire leads, terminals, and metal inserts firmly in the lower mold during closing. Ideal layout for strain relief grommets, plug overmolding, and wire harness encapsulation.

● Low-Pressure Mold Closing Protection: Switches to a low-pressure phase during the final closing stroke before full clamping force engages. If an insert or wire is misaligned, the machine automatically halts before applying 25 tonnes of pressure—preventing mold face damage and insert crushing.

● Three-Stage Independent Thermal Profiling: 3-zone barrel and nozzle heating control provides precise temperature gradients. Prevents material burning, nozzle drool, or structural degradation when processing engineering thermoplastics like PVC, PA, ABS, and PE.

● Liftable Barrel & Nozzle Assembly: The barrel and nozzle can be lifted clear of the mold area via an integrated mechanism, allowing rapid nozzle purging, color changes, or maintenance without removing the mold tool.

Application Range

● Automotive Wire Harness Connector Overmolding: Precision molding of waterproof connectors, sensor plugs, rubber grommets, and strain relief boots onto pre-stripped wire assemblies.

● Consumer Electronics & Power Cord Manufacturing: High-speed overmolding of USB-C plugs, DC power jacks, AC line plugs, and audio connectors.

● Industrial Automation & Sensor Encapsulation: Encapsulating M8/M12 industrial connectors, proximity switch housings, and PCB relay terminals.

● Medical Equipment Cable Assemblies: Low-pressure, cleanroom-ready overmolding of medical cable strain reliefs and custom probe connectors.
