Sprue sets are usually made of high carbon tool steel. Injection mold sprue design elements are as follows: 1. To facilitate gating system condensate material pulled from the main road in and consider expansion of the plastic melt, sprue design into a cone. 2. The big end of the main channel was rounded with a radius take r = 1 ~ 3mm, in order to reduce the flow rate of the steering transition resistance. 3. ensure the plastic forming under good conditions, the length of the injection mold sprue should be as short as possible, otherwise it would increase the sprue slug, and increase the pressure loss, acrylic products manufacturers, the plastic melt to cool excessive Injection forming. 4. molten plastic completely into the main channel without overflow, should be the main channel of the injection machine nozzle tight butt, butt joint is designed sprue hemispherical pits. Sprue parts are frequently designed to be disassembled sprue bush, acrylic, to high quality steel processing and heat treatment alone, so the use of electric heating in the main channel of the material in order to raise the temperature. 4, the manufacturer should have the CNC, EDM, EDM and CNC profile milling equipment, preferably acrylic products, high-precision grinding machines, high-precision coordinate measuring instrument, acrylic products, plastic mold, computer design and related software . 5, generally large stamping dies (such as car cover mold) to consider whether the machine has a pressure side organizations, and even edge lubricants, multi-position-forward. In addition to the tonnage stamping also consider pumping, feeding equipment, machine tools and mold protection. 6, the mold manufacturing methods and processes, and not every company has mastered. When choosing collaboration manufacturers must understand its processing capacity, not only to see the hardware, but also with management, processing experience and technical strength. Acrylic products exporters, integration into a plastic mold factory (online consultation), integration into the acrylic by the Shenzhen Municipal Science and Technology Limited. Shenzhen harmony Technology Limited (www.rhctech.net) Guangdong Shenzhen, plastic products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. The integration into a plastic mold factory leadership with the staff warmly welcome all inquiries negotiations to create harmony into a plastic mold manufacturers a better future.
