Thermoplay Molding Solutions | Hot Runner Systems

Our Know-how at Your Service
High Performance Hot Runner Systems

Our injection molding system offers modular components for simplified maintenance and a consistent thermal profile thanks to our special patented heater. Sintered special steel tips provide optimal thermal conductivity and exceptional wear resistance. With variable length options and single nozzles compatible with all tip types, we offer flexibility and ease of use. In addition, our color change option allows smooth transitions between materials during production.

Advanced Injection Molding Solutions: Efficiency and Versatility

Thermoplay nozzles are designed with modular components, making maintenance fast and efficient since parts can be replaced directly inside the machine. Thanks to our patented heater, they ensure a constant thermal profile and significant energy savings, while tips in special sintered steel provide excellent thermal conductivity and long-lasting wear resistance.

Available in different lengths and with single nozzles compatible with all tip types, they guarantee maximum flexibility. The color change option further enhances productivity, allowing smooth transitions between materials during production.

Our nozzle series includes:
- TF/FN: suitable for all thermoplastics
- TD/DN: simple design and easy manufacturing of nozzle seats
- KS: standard multi-tip and side-gate solutions

Plate actuated valve gates solutions

Our synchronized valve gate actuation system ensures perfect timing in opening and closing cavities while maintaining a compact footprint and maximizing process efficiency.

The system can be actuated pneumatically or hydraulically, offering flexibility for various applications. Each pin stroke can be mechanically adjusted independently (PATENTED), and individual pins can be excluded on cavities with spacing greater than 38 mm (PATENT PENDING).

Cavity opening, closing, and pin adjustments can all be performed directly on the machine, while the system supports minimum nozzle spacing of 38 mm with breaker and pin adjustment, 22 mm with only pin adjustment, and 17 mm without any device.

This solution combines precision, compact design, and adaptability, optimizing cavity control and enhancing the efficiency of the entire injection molding process.
