High gloss mold temperature known as the rapid heat & cool mold temperature controller, designed to solve, such as a weld mark, ripple, floating fiber, optical alignment color, deflated, lack of material, and the stress concentration and other injection molded article quality, people to take a number techniques measure, comprising: optimizing the mold design (e.g., layout optimization cavity and waterways), optimization of the injection process (including a control mold temperature, speed and pressure, and dwell blank range and the like), and the combined hot runner technology, Gas-assisted technology and heat treatment technology. Nevertheless, these measures are still difficult to solve the problem fundamentally. The painting process afterthought despite remedy the aforementioned drawbacks, but often leads to higher costs and scrap rates, and its production is not environmentally friendly (benzene). As a new technology developed in recent years, the high-gloss no-melting injection molding system has become a new solution to the above problems.
