Injection molding process flow chart
The process of injection molding is a very complex process, especially precision injection molding, which involves professional knowledge in all aspects. Although the injection molding process of different products is not much different, the process is still somewhat different. The steps of the injection molding process flow chart are briefly sorted out.
1. Injection molding product process parameters
It is necessary to design the composition of the injection molded product, as well as the type of plastic used, the quantity produced, the date of delivery, the quality requirements, etc.
2. Design and manufacture of injection molds
After a detailed analysis of the injection molded product, the mold design and manufacture are required.
3. Purchase of plastic particles
What kind of plastic is used for injection molding products, such as: PC plastic, COP plastic, PFA plastic, etc.
4. Debugging and cleaning of injection molding machines
It is necessary to clean the head, barrel, screw, nozzle, etc.
5. Installation and debugging of molds
After the mold is installed, a small batch of products can be tested in the early stage. This process requires debugging the injection molding machine until there is no problem with the quality of the injection molded product, and then mass injection production begins.
The following process also involves such processes as baking, filling, pressure holding, cooling, demoulding, surface quality inspection, final inspection, warehousing and delivery, etc. The injection molding process needs to be carried out strictly in accordance with the relevant steps.
