Plastic CNC machined parts refer to components made from plastic materials that are manufactured using CNC (Computer Numerical Control) machining processes. CNC machining is a subtractive manufacturing method where computer-controlled machines precisely remove material from a plastic workpiece to create the desired shape and dimensions.

General precision injection molds have two indicators, namely equipment accuracy and mold error. The former is difficult to compare due to the difference in size and product thickness, and represents the comprehensive level of injection molding machines. Generally, the weight repetition error of ordinary injection molding machines is 1%. A good machine can reach 0.8%, less than 0.5% is a precision machine, and less than 0.3% is an ultra-precision machine. So what are the main factors affecting precision injection mold products?

CNC (Computer Numerical Control) machining is a highly versatile manufacturing process capable of producing parts from a wide range of materials, including plastics. This technology utilizes computer-controlled tools to shape materials with precision and efficiency. When it comes to plastics, CNC machining offers numerous advantages, making it a preferred choice for creating prototypes, custom parts, and even small production runs.

For injection mold processing, the hardness of the cavity part is generally required to be one value, and occasionally higher. The processing methods that can be used after thermal disposal are limited to special processing such as grinding, electrical processing and chemical corrosion, but CNC milling and machining centers can also be used to process, but the cost of the tool is expensive, so the focus of the process is how to divide which processing is placed before thermal disposal and which is placed after thermal disposal, so as to minimize the old cost, improve efficiency and wrap quality.

The traditional five-axis CNC machining process may cause waste parts due to temperature or other processing techniques. Unlike ordinary metal processing, some rubber or plastic molds cannot be recycled after being scrapped. For enterprises The five-axis processing of rubber molds may greatly affect the net profit, but the choice of five-axis processing of rubber molds shows many advantages.

The characteristics of plastic injection molding are determined by the characteristics of the raw material, and there are two main points: one is the filling activity of the plastic melt during injection, and the other is the shrinkage position of the plastic in the mold cavity when it is cooled and cured. These two points determine the difference of the injection mold and the difficulty of the injection mold design. When designing injection molds, it is necessary to inquire about the characteristics of the processed plastic raw materials, so that the designed injection mold is more reasonable, and the characteristics of plastics are usefully exercised in the design process. Therefore, the questions that need to be considered in the injection mold design process are as follows.
