Valve Gating for Injection Molding of Large Air Conditioner Structural Components
Challenges
  • The air conditioner structural components had a large volume, with dimensions ranging from 80 to 100 cm and weights exceeding 2.5 kg.
  • Strict quality requirements were in place, with the front cover having multiple A-grade surfaces.
  • The aesthetic demands were high, prohibiting the presence of air marks, flow marks, impurities, color variations, visible joint lines, and more.
  • Given the substantial size of the products, the flow-to-length ratio was considerable.
Solutions

To address these challenges, a valve gating system with five needle valves and delayed gating was employed. The injection sequence involved initially opening gate 1, followed by gates 2 and 3, and finally, gates 4 and 5.

Solutions
Results

The appearance yield rate reached 97.5%, demonstrating a significant improvement in product quality. Moreover, there were zero customer complaints regarding product defects, indicating a successful implementation of the valve gating solution.
