Making plastic injection molding process: in order to ensure the plastic molding process smoothly, satisfy the use requirements of qualified products, before the design of the injection mold for injection molding process, first of all to develop reasonable.
  Plastic molding process is plastic with process document guiding molding production, is an important basis for the organization of production, production personnel must strictly implement. Division of labor more detailed factory, is a specialized personnel of plastic molding process to complete the formulation molding process. Die design personnel can and do the work. Process for the preparation of plastic injection molding process generally includes the following contents.
1.confirm the injection molding process, based on the analysis of plastic parts, according to the characteristics of plastics and plastic parts requirements, production quantity, structure processing and plastic molding equipment, once again confirmed the injection molding is the best molding method of plastic parts.
2.The formulation of the injection molding process, formulation of molding process including pretreatment, plastic injection molding process and molding processing and two processing etc.. In determining the process, according to the needs of the relevant procedure arrangement in the proper position, obtain most satisfactory technical and economic effect to ensure.
3.To determine the injection molding process conditions, the plastic should be in appropriate conditions to the injection molding of qualified products. In the injection molding process conditions, temperature, pressure and time are the three most important factors, the relationship between them closely. When the choice must be analyzed according to the characteristics of plastics and the actual situation, first determine a preliminary test conditions according to the actual situation, after the test mold and plastic parts inspection result, finally to determine the conditions of formal, and the process conditions of the control request.
4.Figure the choice of injection molding machine, the overall structure of the mold according to the type of injection machine initially selected, so before the die structure design, you must select the injection molding machine, mold design is gradually carried out in the main technical parameters of the injection molding machine under the conditions to meet the. Injection molding, injection molding is according to a desired total volume or quality of the plastic injection machine models and specifications.

5.The formulation of the process documents, process documents is the content and the parameters of the process planning are summarized, in the form of documents properly confirmed, as the production preparation and production process. The process generally includes process specification, process card, wherein the plastic production process card is the most important. According to the production program, process card contains the content is different, but the basic content must have. Card format can refer to the relevant standards.
