Injection molding advantages of injection molding

1, the injection mold can be used to accurately control the wall thickness distribution of the billet, so that the wall thickness of the obtained container is more uniform, avoiding the thinning phenomenon of the general injection parts, the weight of the injection parts can be controlled in +0.1g, the precision of the thread can be controlled in the range of 100¦ÌM, the mouth size is accurate, and the molding precision of the fine neck products is high.

2, injection parts do not need to carry out multiple processing, no seams, save the finishing of products.

3, injection molding parts of the molded billet can be all into the blow molding mold blowing molding, no waste generated during the processing, reducing the waste of molding materials.

4, can get smooth surface products, no scratches, surface text and pattern clear;

5, can economically carry out small batch production;

6, wide range of application of plastic varieties;

7, high degree of automation, multi-mode production, high production efficiency

Injection molding parts production process

1. Raw material treatment for injection molding parts production

Before the production of injection parts, the raw materials need to be treated first. In general, plastic particles need to be cleaned, impurities removed, and mixed to add the necessary toner and additives. In addition, it is necessary to measure the weight and density of the material before processing.

2. Melting of injection parts production

The treated plastic particles are injected into the injection molding machine and melted by heating. In an injection molding machine, a screw pushes the molten material forward. As the screw rotates, it also acts as a mixer to ensure that the plastic particles melt evenly.

3, injection molding production of injection parts

The melted plastic particles will be injected into the mold through the nozzle of the injection molding machine. The mold is a pair of metal constructed molds that completely seal the material, and through the process of spraying plastic particles, the injection molding part is formed inside the mold. Mold manufacturing must pay attention to the material type, size, shape and surface treatment requirements of injection parts.

4. Cooling of injection molding parts production

After the injection molding process is completed in the mold, the injection molding part needs to be given a cooling time. Injection molded parts will deform during cooling, so strict control of cooling temperature and time is required to ensure the quality of injection molded parts.

5. Release mold for injection molding production

After the injection molded part is completely cooled, it needs to be removed from the mold. In general, the mold is struck with a template to loosen the injection part, and the fixture or other tool is used to remove it. In this step, the surface of the injection molded part needs to be machined to remove burrs.

Our Guangzhou OTEM Engineering Plastics Co., Ltd. has more than 20 years of injection molding parts, plastic parts customized processing operations, with a physical plant, professional production equipment and professional design and development production team, can provide you with satisfactory customized services, to provide you with satisfactory plastic products.

The difference between blister parts and injection parts

1. Different production methods

The blister part is made by baking the sheet hot, and then pushing the sheet out by suction to glue the sheet and the mold, and then by cooling forming.

Injection molded parts are made by using hot melted plastic to extrude the plastic to the injection mold using pressure, and then cooling molding.

2, different types of use

Blister parts are used in electronic products, digital products, toys, stationery, hardware accessories, etc. The types of blister parts are blister box, blister bubble shell, blister tray, blister cover and other types.

Injection molded parts are usually used in mobile phone cases, computer cases, plastic cups, mouse cases, hardware accessories, etc.

3. Different production cycles

Blister is a hot-soft production mode that can be blister multiple products at a time by multiple molds. The production cycle of the injection mold is longer, and it is produced by pressing multiple products of a single mold, and there is no need to directly form the product.

4, from the practical application

Blister parts belong to products in the form of packaging, and injection parts belong to products in the form of items, the same is that both belong to plastic products.

The design of injection parts needs attention

1, the shape of the injection parts should be as simple as possible, reasonable, easy to shape

2, the wall thickness of the injection parts should be reasonable

3, injection parts must be set the necessary release slope

4, the strength and stiffness of injection parts can be considered to design reinforcement

5, all corners of the injection parts are designed as rounded corners or arc transitions as possible

6. Dimensional tolerance of injection parts
