Why Cooling Time Optimization Matters in Injection Molding

Did you know cooling time accounts for more than 60% of the entire injection molding cycle? At Dongxinda, we help our clients reduce cycle time—and increase output—by optimizing cooling systems right from the design phase.

Key Cooling Optimization Strategies:

• Conformal Cooling Channels: Follow part geometry for uniform temperature reduction.

• High Conductivity Inserts: Materials like beryllium copper speed up cooling in hot zones.

• Balanced Cooling Circuits: Prevents uneven shrinkage or warpage.

• Simulation Analysis: We use software to predict cooling performance before machining.

Proper cooling improves part consistency, shortens cycle time, and extends mold life.

FAQs:

• Can you simulate cooling performance before mold build?
  Yes, we provide Moldflow-based thermal simulations with every high-precision project.

• What’s the typical cooling time saving with improved design?
  Up to 20–30% depending on part thickness and material.

• Do you integrate temperature sensors in molds?
  Yes, especially for complex or high-value tools, we offer embedded thermal control.
