PET Preform Production: The Integration of Hot Runners and Injection Molding Machines

The symbiotic relationship between hot runners and injection molding machines is irreplaceable. The selection of an appropriate injection molding machine is crucial for the seamless integration of the hot runner system. Therefore, when choosing an injection molding machine, we should take note of the following points:

1. To minimize the wear and tear of hot runner molds, it is encouraged to operate the injection molding machine continuously, reducing the lifespan erosion through multi-stage startups.
2. When measuring the injection volume, the compressibility of plastic in large-volume runners must be taken into consideration.
3. The introduction of additional runner plates in hot runner molds increases the thickness. It is essential to pay special attention to the installation height of the injection molding machine during the selection process.
4. To ensure the automatic operation of the molds, various devices such as robots or easily controlled mechanical hands can be employed. These devices can be utilized for:
   a. Ejecting plastic parts or speeding up demolding.
   b. Reducing the time for mold closing, shortening the connection time for cooling water pipes, air circuits, electrical circuits, and hot runner temperature controllers.
   c. Placing inserts, labels, or films into the molds.
   d. Preheating the molds before starting the injection molding machine.
   e. Controlling the movement of plastic parts, reducing startup time, and minimizing the use of accessories.
