What is Hot Plate Welding?

The process of hot plate welding uses a heated platen to melt the joining surfaces of the two halves of a thermoplastic part. The part halves are brought into contact with a precisely heated platen for a predetermined period. After the plastic interfaces have melted, the parts are brought together to form a molecular, permanent, and often hermetic bond.

Main Features
  • Equipped with PLC & HMI touch screen with English interface.
  • CNC machined components with high-precision assembly.
  • Optional hydraulic drive for stable, waterproof & airtight performance.
  • Famous imported brands: Airtac pneumatic parts, Mitsubishi PLC, etc.
  • Precise PID digital temperature control (±0.5 ℃).
  • Fast and convenient welding jig changeover.
  • Stable structure & heavy-duty design for industrial production.
