Pet Bottle Mould Hot Runner System To Improve Efficiency

When deciding to incorporate a hot runner system into a Pet Bottle Preform¬†mold, the question is which attributes must be considered? Since there are many independent vendors on the market, the types and choices of systems are often similar to different systems. In this case, let’s look at how to choose the right hot runner system.
Hot runner technology has many options. In order to improve the molding efficiency and the quality of the parts, in some cases the price takes precedence over the application. Here are some of the hot features and vendor support aspects to consider before making a purchasing decision:
1. After sales service
In addition to sales, it is important to ensure that the supplier provides product service, training and start-up assistance. These traces are very important for an effective installation.
2. Product series products
To achieve the best system for molding applications and maximize design flexibility, suppliers must offer a wide range of nozzles, including hot nozzles, valves and edge gates, hot gates, multiple nozzles, and more.
3. Resin testing
Check out a fully equipped resin testing or R&D facility to help OEMs or moldmakers choose the best hot runner system type. In addition, resin flow, channel size, and various other design capabilities should be balanced to produce a thermally balanced hot runner system. In such systems, the flow path is large enough to produce a relatively small pressure drop across the system without causing excessive residence time when casting the injection mold.
4. Easy to maintain
Finally, easy maintenance defines the level of maintenance of the system. Your runner installation decision should answer the following questions:
Can the door in the machine be cleaned?
Is it possible to replace worn parts such as nozzle tips, thermocouples and heating belts without removing the Pet Bottle Mould from the machine?
Can the stem in the valve control system be adjusted or replaced in the molding machine?
All of these tips are useful when installing a hot runner system to enhance the injection molding process. The use of hot runner systems reduces cycle time (easy to maintain), energy and material costs, thereby increasing overall molding efficiency.
