Precision Unscrewing Injection Molds for Threaded Plastic Parts Reliable and Cost-Effective

The unscrewing mold utilizes a servo motor to rotate the core, allowing the threaded product to be automatically demolded after forming. This avoids precision loss caused by forced ejection while ensuring product appearance and consistency.

1. Determine thread standards and cavity structure
2. Mold flow analysis and rotation simulation
3. CNC/EDM finishing and heat treatment
4. Assembly of servo drive and cooling water lines
5. Trial mold and sample confirmation

• Suitable for injection molding of high-precision threaded parts
• Can meet high-volume production needs
• Supports customized design and processing

• High precision, intact threads
• High degree of automation
• Easy mold maintenance
• Long service life

• Q1: Can double-start or multi-start threads be produced?
  A1: We offer custom thread solutions.
• Q2: Will the threaded part get stuck in the mold?
  A2: No. Automatic unscrewing mechanisms prevent the risk of jamming.
• Q3: What is the typical mold lifespan?
  A3: On average, 800,000–1.2 million mold cycles.
• Q4: Is it suitable for transparent plastics?
  A4: Yes. The cavity can be mirror-polished.
• Q5: Do you provide samples?
  A5: Free trial samples are provided for customer verification.

We can customize thread diameter, pitch, and core structure, supporting flexible solutions with multiple cavities and automated interfaces.
