The injection molding equipment is used to heat and melt hot melt and thermosetting plastics, apply a certain pressure to fill them into the mold, and then solidify into a mold after cooling. Today, let's not talk about the working principle of the injection molding machine, but mainly talk about the advantages and disadvantages of the injection molding process.

The injection molding equipment is used to heat and melt hot melt and thermosetting plastics, apply a certain pressure to fill them into the mold, and then solidify into a mold after cooling. Today, let's not talk about the working principle of the injection molding machine, but mainly talk about the advantages and disadvantages of the injection molding process.

Advantages of the injection molding process

1. The wall thickness distribution of the parison can be precisely controlled by the injection mold, so that the wall thickness of the obtained container is relatively uniform, avoiding the thinning phenomenon that is easy to occur in the corners of general blow-molded products, and the weight of the product can be controlled at + 0.1g, the precision of the thread can be controlled within the range of soil 100μM, the size of the mouth is accurate, and the forming precision of thin neck products is high;

2. The obtained product does not need to be processed for E times, without seams, saving the finishing time of the product;

3. The parisons made by injection can all enter the blow mold for inflation molding, and no waste is generated during the processing, which reduces the waste of molding materials;

4. Products with smooth surface can be obtained, without scratches, and the surface characters and patterns are clear;

5. Small batch production can be carried out economically;

6. Wide range of application to plastic varieties;

7. High degree of automation, multi-mode production, and high production efficiency.

Disadvantages of the injection molding process

1. Two sets of molds for injection molding and blow molding and a hollow core mold with a valve must be used for product molding, and the mold for injection parison should be able to withstand high pressure, and the cost of molding equipment is high;

2. The temperature of the injection parison is relatively high, which requires a long cooling and setting time after inflation in the injection mold, which prolongs the entire molding cycle of the product and affects the production efficiency;

3. The internal stress of the injection molding parison is large, and it is easy to be unevenly cooled in the process of changing the mold. When producing products with complex shapes and large sizes, stress cracking is prone to occur. Therefore, the shape and size of the products are limited and are only suitable for production. Small products are used in cosmetics, daily necessities and pharmaceutical packaging, food packaging and other fields;

4. The operator's are required to have higher operating skills.
