We offer a combined process technology that performs injection molding and punching/cutting within one mold. By strictly controlling cooling system design and structural rigidity, we eliminate warpage and sink marks at the source, ensuring consistent dimensional accuracy and surface quality.
Our Insert Mold tooling is engineered for high‑appearance, high‑volume injection‑molded products that require zero gate marks on visible surfaces. The in‑mold punching structure removes scrap through a punching action during mold clamping, followed by the injection molding process.
A vacuum suction unit extracts the cut scrap from the mold cavity.
High‑hardness, wear‑resistant tool steel combined with surface coating technology ensures long tool life.
Precision manufacturing CNC machining and EDM guarantee component accuracy.
A precision multi‑stage guidance system ensures alignment throughout the punching process.
Integrated one‑shot molding tooling delivers precision for connectors and structural parts in home appliances, automotive, and industrial equipment.
Process Optimization: During early DFM analysis, we proactively identify and mitigate risks of sink marks, flash, and demolding issues. High‑precision CNC and EDM machining ensure tight mechanical interlocking between plastic and metal, preventing separation or loosening.
Dimensional Precision: High concentricity and consistent pitch spacing are essential to avoid pin tilting, misalignment, or improper assembly fit, supporting fully automated production. Moldflow analysis with pre‑deformation design, combined with our proprietary pre‑deformation database, ensures compliance with 2D drawing tolerance requirements.
Manual touch‑up operations are eliminated, reducing labor costs and avoiding pin bending or short‑circuit defects from hand rework. Tight dimensional tolerances are maintained, with sealing surfaces and metal insert areas free of weld lines, step mismatches, gas traps, or other defects.
Traditional injection molding of insert assemblies needs secondary trimming after molding and struggles to satisfy modern manufacturing requirements. Our in‑mold trimming design achieves injection molding and trimming in one forming operation.
Refrigerator door handles (metal inserts for enhanced strength), washing machine control panel frames (metal‑plastic bonding for improved rigidity), air conditioner decorative trims (with embedded metal brackets), oven door assemblies (metal frames for heat resistance, plastic for insulation and aesthetics).
Instrument panel cross‑beam carriers (metal carriers embedded in plastic for lightweighting and high strength), ECU housings (with integrated metal shielding inserts), sensor connectors, and other automotive components.
