The hot runner role in injection molding

80 %of life goods need to through the injection molding

Mold is closely related to our life, More than 90% of the life of the article to be processed through the die is made,While 80% of goods go through the plastic molding, plastic mold temperature should reach 300 ℃ or more. Due to the special shape of the plastic mold, with traditional insulation materials can not be insulated on the lower mold high temperature heat loss of a great, severe heat loss, high temperature metal mold thermal fatigue loss is large, and so on. Plastic mold heat great loss, not only directly increase the cost of production, but also due to frequent replacement of the mold caused by mass production line shut down frequently result in greater economic losses.

Hot runner injection molding is used in conjunction with the mold, and play a very important role, such as in the production of ultra-thin plastic injection parts, by using the runner can easily produce high-precision, high-quality products out; for illiquid injection molding material by using a runner can improve the flow of raw materials, to ensure smooth production of injection molding; for some large plastic parts such as car bumpers and door panels, rear shell TV, air conditioning and so on through the hot runner can shell very difficult injection molding becomes relatively simple.

Ues hot runner to reduce injection molding products cost

In the multi-cavity injection mold, the lack of hot runner molding is difficult, it can be said so far is to ensure the hot runner runner balance of the best technology. Because of the presence of plastic hang shear forces in the flow, regardless of the geometry of a mold having more than a reasonable balance, the weight of the molded product is difficult to come out of the same, especially in terms of multi-cavity molds.

For plastics processors, as long as there is a certain volume of injection molding using a hot runner it is quite economical, because the hot runner nozzle to help businesses get rid of in the production of injection molding, which not only saves raw materials, and to cut labor costs and make products more perfect appearance. We all know that in most cases the drain can not be reused, if not at times the weight of the hot runner nozzle and the weight of the product is almost, if the traditional way means that the injection nozzle producing a product must be a product of almost a waste of raw materials as waste, and therefore only this not only saves raw materials, and to cut labor costs, but also make the product more perfect and beautiful. In addition, the runner also help reduce mold wear, extend die life. In general, the hot runner mold life is twice as small inlet of the mold.

Our company offers a reasonable solution

Runner simple composition, but each component plays an important role. Generally good quality hot runner design and structure of the material requirements are very high. We can according to the customer's product, the design a reasonable solution, to ensure the hot runner injection molding system can play a maximum efficiency. As our company uses Han Guorui runner, the choice of heaters and temperature line all imported from South Korea, the steel used for all materials imported from Japan, which is to ensure the quality of these hot runner prerequisite.
