🟡 Injection molding process optimization
✅ Mold design and flow channel balance
Mold temperature control to ensure flow balance and avoid short shots and bubbles.
Selection and optimization of hot runners and cold runners.
✅ Injection molding parameter optimization
Through scientific mold trials of the injection molding machine, adjust parameters such as injection speed, holding pressure, back pressure, cooling time, etc.
Use CAE simulation software (such as Moldflow) to predict filling, warping, and stress concentration.
✅ Material selection and drying
Rationally select resins and additives to improve fluidity.
Pre-drying controls moisture content to avoid bubbles and silver streaks.
✅ Cycle time reduction and energy consumption management
Quick mold change system to reduce downtime.
Energy-saving servo motor and thermal management optimization.
🟡 Extrusion molding process optimization
✅ Screw and barrel design
Optimize the screw structure (such as barrier screw, mixing zone, etc.) according to material viscosity and output requirements.
Improve plasticizing effect and improve melt uniformity.
✅ Temperature control and melt pressure control
Precisely control the temperature of each temperature zone to ensure uniform plasticization of the material.
Real-time monitoring of melt pump or melt pressure sensor to reduce fluctuations.
✅ Extrusion speed and traction speed ratio
Match the extrusion speed and traction speed to avoid uneven wall thickness of the product.
Balance between interlayer ratio and interface bonding during multi-layer co-extrusion.
🟡 Blow molding process optimization
✅ Parison temperature and wall thickness distribution
Extrusion parison temperature is stable to avoid wall thickness differences caused by uneven heat.
Optimize mold cooling system to ensure uniform product thickness.
✅ Blowing pressure and speed
Control the blowing time and pressure to prevent collapse or rupture.
For hollow products, avoid excessive bottom thickness and too thin top.
✅ Secondary cooling and shrinkage control
Reasonably arrange mold cooling cycle time to prevent warping and dimensional instability.
Use vacuum shaping or auxiliary air cooling to achieve higher production capacity.
