Although domestic hot runner production started late, it grew rapidly and the market proportion was expanding. After the market was opened in the early stage depending on the period and price, the quality of domestic heat flow track was also rapidly improved.

Hot runner mould has many advantages such as short forming period, saving raw materials and being conducive to automation. However, if the quality is not well controlled, there are also many problems, such as complex structure of hot runner, polishing difficulty, aesthetic appearance of injection molding parts, and surface smoothness. How to polish quickly and efficiently and precisely has become one of the core objectives of many heat flow path manufacturers to improve their competitiveness.

In order to maintain the overall precision of hot runner die, many enterprises have begun to use fluid polishing technology to polish the hot runner. This process is different from other ways. When using high molecular soft abrasive to polish quickly, the mold is held in by the fixture, and the work piece will not be hurt due to uniform force. The following figure is the actual picture of fluid polishing. Soft abrasive can be polished completely without dead angle by passing through the surface and internal pores of the workpiece in the hot runner.
