Shorten the processing cycle and increase efficiency.
· Instead of cold runners, no material handles (nozzles) are produced and no further crushing is required.
· Improve product consistency and improve product quality.
· Improve the appearance of the product.
· Reduce product stress and reduce product distortion.
· Using valve gates, step-by-step injection molding, processing and manufacturing parts series of different specifications.
· Provide more engineering controls to fine-tune the injection molding process.
The performance of key performance elements of the hot runner system:
· Precise control of melt plastic temperature and eliminate material degradation.
· Balanced runner design, the part cavity is evenly filled.
• Suitable hot nozzle sizes ensure smooth flow of the melt and adequate filling of the cavity.
·The correct gate structure and size ensure that the cavity is fully filled and the needle valve gate is closed in time, thus reducing the casting and shortening the injection cycle.
·There is no dead zone in the flow channel to ensure fast color change and prevent material degradation.
• Minimize pressure loss and reduce clamping force.
· The pressure keeping time is reasonable.
The correct use of the hot runner system will increase production efficiency by approximately 20% to 30%, making the molding industry more competitive.
