Customer Case Study For Wingtat - China

Challenges Faced by Zhongqing:

1 - High-Transparency Material Issues:

- Difficulty achieving desired transparency in molded components.

- Instances of fusion lines affecting the surface quality.

2 - Molding Fusion Line Control:

- Fusion lines appearing at convergence points during the injection molding process.

- Adverse effects on product strength and aesthetics.

3 - Large Injection Molding Machine (1200T) Constraints:

- Inability to meet the production demands efficiently.

- Hindered the smooth flow of the manufacturing process.

Wingtat's Comprehensive Solutions:

1 - Mold Design for Transparency and Fusion Lines:

- Employed advanced Moldflow simulations for accurate prediction of fusion line locations.

- Implemented precise timing of sequential hot runners to eliminate transparency and fusion line issues effectively.

2 - Addressing Common Molding Issues:

a.

Insufficient Melt Flow:

- Increased melt temperature to enhance flow characteristics.

- Accelerated injection speed to prevent melt cooling before reaching convergence points.

- Elevated mold temperature to minimize melt temperature reduction.

- Optimized gate design and part thickness to reduce flow resistance.

b.

Air or Volatile Components:

- Integrated venting through parting lines and designed dedicated venting channels.

- Ensured effective removal of air or volatile components during the molding process.

c.

Release Agent Impact:

- Minimized the use of release agents, especially those containing silicon.

- Mitigated potential issues arising from the interaction of release agents with the melt.

d.

Colorant Influence:

- Acknowledged challenges in eliminating fusion lines caused by the addition of colorants.

- Collaborated closely with Zhongqing to optimize colorant choices for improved results.

3 - Mold Defects and Structural Modifications:

- Implemented structural modifications to address persistent fusion line issues.

- Adjusted gate placement to minimize the visibility of fusion lines.

- Balanced system parameters to ensure consistent and optimal results.
