Our multi-material plastic molds integrated with gas-assisted injection molding technology are engineered to produce high-precision, complex plastic parts with superior structural integrity, reduced material consumption, and enhanced design flexibility. This advanced solution combines the versatility of multi-material molding (e.g., hard-soft combinations, rigid-flexible assemblies) with the efficiency of gas-assisted molding, ideal for automotive, consumer electronics, medical devices, and household appliance industries.
Whether you require two-shot molding (overmolding/insert molding) or gas-assisted hollowing for thick-wall components, our molds deliver consistent quality, shortened cycle times, and cost-effective mass production.

Core Advantages

  1. Multi-Material Versatility
    • Support combinations of thermoplastics, elastomers, and engineering resins (e.g., PP+TPE, PC+ABS, PA66+TPU).

    • Enable one-step production of integrated parts with diverse properties (rigidity, flexibility, wear resistance, insulation), eliminating post-assembly processes and reducing labor costs.

  2. Gas-Assisted Molding Excellence
    • Hollow structure forming: Inject inert gas (nitrogen) into the melt to create internal hollow channels, reducing part weight by 10–30% while maintaining mechanical strength.

    • Eliminate defects: Minimize sink marks, warpage, and residual stress in thick-wall sections, ensuring smooth surface finish and dimensional accuracy (tolerance ±0.05mm).

    • Lower injection pressure: Reduce clamping force requirements by 20–40%, extending mold lifespan and cutting energy consumption during production.

  3. Precision & Durability
    • Mold cavities and cores are machined with 5-axis CNC and EDM technology, ensuring high repeatability and tight tolerances.

    • Adopt premium mold steels (e.g., S136, H13, P20) with hard chrome plating or nitriding treatment, achieving a mold lifespan of 500,000–1,000,000 shots.

    • Equipped with precision hot runner systems and temperature control modules for uniform melt flow and material bonding.

  • Consumer Electronics: Smart phone cases (rigid PC + shock-absorbing TPU), laptop hinges, and wearable device straps (flexible multi-material structures).

  • Medical Devices: Disposable syringes with soft gaskets, surgical instrument handles (non-slip, ergonomic design), and diagnostic equipment housings.

  • Household Appliances: Vacuum cleaner hoses, blender blades with rubber seals, and refrigerator door gaskets.

Our Service Process

  1. Customization Consultation: Discuss your part design, material requirements, and production volume.

  2. DFM Analysis: Provide Design for Manufacturability reports to optimize part structure for multi-material and gas-assisted molding.

  3. Mold Design & Simulation: Use CAE software (Moldflow) to simulate melt flow, gas penetration, and cooling, minimizing trial-and-error cycles.

  4. Mold Fabrication: Precision machining, assembly, and strict quality inspection (dimensional measurement, pressure testing).

  5. Trial Run & Sampling: Conduct mold testing, adjust parameters, and provide sample parts for customer verification.

  6. Mass Production Support: Offer on-site technical guidance, mold maintenance, and spare parts supply.
