Plastic molds are molds that can shape thermoplastic materials, such as plastic shells in your daily life, such as TV cases, computers, remote controls, pots, buckets, plastic stools, and so on. Next, let's talk about the process and precautions for opening injection molds.
Injection mold opening process

1. Drawing design is the first step in mold making, and it is necessary to communicate well with the customer and complete the drawing design according to their needs

2. Choosing the right materials to make the mold based on the nature of the product directly affects the quality of injection molding after the mold is formed

3. The mechanical processing of molds includes CNC machining, EDM machining, wire cutting machining, deep hole drilling machining, and so on.
4. Before mold testing and repair, a detailed analysis and research should be conducted based on the actual situation of the defects that occur in the plastic parts

5. After the successful trial of the mold, it can be put into production. If not in production, additional molds need to be protected and relevant technical parameters need to be organized and documented

Precautions for opening injection molds

1. The cooling (water passage) in the mold is related to factors such as product size, shape, plastic properties, and holding time

2. Plastic molds must have sufficient rigidity, otherwise deformation may occur during mold clamping and compression, causing "flying edges"

3. The shrinkage coefficient of each material is different, and the mold should have a reasonable shrinkage rate

4. Choose a reasonable demolding method, select a reasonable position and quantity of ejector pins to ensure that the product is not damaged during the ejection process
