Application Range Of Hot Runner Molds

Application range of hot runner molds

The cold runner is the part between the mold inlet and the product gate. The plastic is kept flowing in the runner by injection pressure and its own heat. The runner is part of the molded material, but not the product. Therefore, when designing a mold, we must consider not only the filling effect, but also how to save material by shortening and narrowing the runner. Ideally, this is the case, but in practice it is difficult to achieve both.

plastic mold

Hot runner, also known as runnerless, means that the plastic in the runner does not solidify after each injection and the nozzle in the runner does not need to be removed when the plastic product is demolded. Since the plastic in the runner has not yet solidified, the runner remains open for the next injection.

Hot runner molds are mainly used in the following areas.

1、Type of plastic material

Hot runner molds have been successfully used to process various plastic materials. Such as PP, PE, PS, ABS, PBT, PA, PSU, PC, POM, LCP, PVC, PET, PMMA, PEI, ABS/PC, etc. Any plastic material that can be processed by cold runner molds can be processed by hot runner molds.

2、Part size and weight

The smallest part made by hot runner mold is under 0.1 gram. The largest is over 30kg. The application is extremely wide and flexible.

3、Industrial field

Hot runner molds are widely used in various industrial sectors such as electronics, automotive, medical, daily necessities, toys, packaging, construction, and office equipment.

Eight common injection mold structure classification One. Single parting surface injection mold When the mold is opened, the movable mold and the fixed mold are separated, so as to take out the plastic parts, which is called single parting surface mold, also called double-plate mold. It is the simplest and most basic form of injection mold, which can be designed as single-cavity injection mold or multi-cavity injection mold according to the need, and is the

The difference between injection moulds and plastic moulds Many people can’t tell the difference between injection molds and plastic molds, and many people even think that they are the same kind of molds, just called different. Although injection molds and plastic molds are both molds, but there is a difference between them. Want to figure out the difference between the two, first and Xiaobian together to understand what is injection mold, what is plastic mold.
