Thermal Stress Management: With a 10x difference in shrinkage rates between metal inserts (e.g., connector terminals) and plastics, Baihao’s insert preheating system (150-220°C precision control) and shrinkage compensation algorithms reduce interface stress cracking to <0.3%.
Molecular-Level Bonding: For TPE overmolding on rigid substrates (PC/ABS), polar modification technology enhances interfacial adhesion. Baihao’s database covers 200+ material combinations, achieving peel strength >15N/cm.
Micron-Level Deformation Control
Mold Thermal Deformation Compensation: In automotive ECU connector insert molding, gradient mold temperature control (≤1.5°C cavity variation) and pre-compensated structural design ensure 0.05mm flatness tolerance.
Precise Rheology Control: For 0.3mm-thick smartwatch buttons, ultra-high-speed valve gates (300mm/s injection) eliminate flow marks, achieving surface Ra <0.8μm.
Closed-Loop Process Monitoring
Vision-Assisted Insert Positioning: Industrial cameras locate metal components within 0.02mm accuracy; error-proof response time <50ms.
Real-Time Pressure Profiling: In medical catheter handle overmolding, in-mold pressure sensors dynamically adjust packing curves, limiting weight variation to ±0.15%.
