What is the production process of AS resin injection molding?

AS resin is a transparent copolymer that is often used in injection molding to make parts with high precision, transparency and hardness. The following is a detailed explanation of the production process of AS resin injection molding:

1. Pretreatment of raw materials
AS resin needs to be dried before use to reduce water content and ensure processing quality. The molding temperature of AS resin is usually 180℃ -230 ℃, therefore, the temperature must be preheated to reach a predetermined value to ensure the quality of the product molding.

2, mold design and manufacturing
AS resin injection molding requires the use of suitable molds, which involves mold design and manufacturing. First of all, it is necessary to determine the shape and size of the parts, and then design a suitable mold structure, including the lower pressure plate, the moving plate, the clamping plate and the oil inlet. Then, the use of CNC CNC machine tools and other equipment for mold processing and assembly to meet the molding requirements.

3. Processing operation
During the injection molding process, AS resin particles are added to the feed hole of the injection molding machine, after heating and melting, they are injected into the mold through the syringe. After the injection is completed, the parts are cooled through a cooling system to form. The process of injection molding requires high temperature, high pressure and high speed, so appropriate equipment control operations are required.

4. Post-processing
After forming, a post-processing operation is required. These include removing flash rings (which arise from gaps between moulds) and cutting signs, draining bubbles, and so on. In addition, cleaning and quality inspection are required to ensure that the parts meet specifications and quality requirements.

AS resin injection molding production process is a complex system, which needs to be adjusted according to the specific situation in practical application. The correct use of raw materials, the selection of appropriate molds and equipment, the mastery of processing technology and the strict implementation of operating procedures, can produce high-quality, high-performance AS resin injection products.
