    1,How The Hot Runner System Works?2,The Advantage of Hot Runner Molds Compare to Cold Runner Molds3,The Hot Runner System TypesWhat Is Valve Gate Hot Runner System ?The cold runner of a plastic injection moldrefers to the section between the mold inlet and the gate. The molten plastic maintains its fluidity inside the runner by virtue of the injection pressure and its own heat. However, as a part of the molding material, the runner is not a product. As a result, when designing a mold, we need to consider not only the filling effects, but also the material-saving effect produced by shortening or downsizing the runner; but in actuality, it is not easy for us to have the best of both worlds.this is why we need hot runner mold Also known as the runner-less system, the hot runner is a system in which the molten plastic is not solidified after each injection, so when releasing the plastic part, the gate inside the runner does not have to be released. Since the plastic inside the runner is not solidified, the runner still stays unblocked when the next injection takes place. See full list on moldchina.com Why has the hot runner system been developed? What benefits can the hot runner system bring us? Engineers familiar with the plastic injection molding process all know that the traditional injection molding is always associated with the following disadvantages: a.Hard to fill; b. thin-walled large size parts easy to deform; c. material waste in the runner; d. inconsistent plastic part quality when using a multi-cavity mold, and so forth. The appearance of the hot runner system has provided an almost perfect solution for these problems. Generally speaking, the hot runner system offers the following benefits: ■ Shorter cycle time As it is not limited by the runner cooling time, the plastic part can be ejected in a timely manner after being molded and solidified. For the production of thin-walled small parts, the molding cycle can be kept within 5s. ■ Material saving In a complete hot runner mold, material waste will not occur thanks to the absence of a cold runner. This is of a greater... See full list on moldchina.com The mold that employs a hot sprue for direct or indirect material feeding, is referred to as a hot sprue mold. See full list on moldchina.com Mount the hot sprue and the manifold into the injection mold, and then by way of heating, keep the fluidity of the plastic material after it is out of the barrel. The result is, the product gate seems to be able to contact with the nozzle directly. So, when releasing the product, the sprue is closed under the action of the needle valve. The application of one or more cold runners is thus avoided, realizing wasteless production. The advantages of the valve gate hot runner system include: 1. Shorten production cycle, improve production efficiency; 2. Since the cold runner is replaced, cold slugs will not be produced, thus saving a large amount of raw materials; 3. Improve product consistency, free from obvious gate marks; 4. Remarkably improve product appearance; 5. Help reduce product stress, minimize product deformation and structural brittleness, so the production capacity and life cycle of complex products are improved; 6. Offer more process control, allow accurate adjustment to t... See full list on moldchina.com
