PRO-TDC Series
Dual colored and materials Injection Molding Machine

Features of PRO-TDC Series

  • Value-added products through advanced technology
  • Optimized production improvement in welding, painting, and assembly process
  • Precise control using two separate piston clamp system
  • Excellent response resulting in shorter cycle time
  • Servo motor driving system should improve the improve the repeatability of rotary equipment remarkably (circumference direction +0.01 mm error.)
  • Excellent injection speed with higher operation efficiency

Core Rotation Type-2 Color Injection Molding
After the completion of the 1st injection, completed mold rotates 180. 2nd injection takes place on top of 1st injection. This rotating cycle speeds up the injection process by saving time. In addition, the gate partition of first semi-finished part can be eliminated by 2nd injection molding

Molding Process
Second injection takes place immediately after the first injection process. (Shown below)
