What is the production process of large thick plate blister packaging? Let's analyze it together.

1. Mold making and processing: According to the requirements or sample specifications, first make a blister mold. Generally, gypsum is used to make blister packaging molds, but wood carvings and metal carvings can also be used as molds. After the gypsum mold is made, let it dry naturally or completely dry. Then, according to the specific situation of the concave and convex surface of the product, use a 1-2mm drill bit to drill many small holes in the concave and convex parts of the product. If it is a product such as a packaging box, it is also necessary to drill some small holes around it so that air can be extracted during blister production. After drilling holes in the mold, the gypsum mold must be hardened. The hardening method is to soak it in a saturated solution of concentrated alum and then dry it.

2. After the mold is completely dry, place the mold on the upper iron plate of the vacuum chamber, and then fill the plastic sheet with the appropriate size according to the size of the mold, and then put the sheet into a heated wooden cabinet to make it completely fixed, and then put the wooden cabinet and plastic sheet into a constant temperature furnace for softening.

3. Put the softened plastic sheet and the wooden cabinet into the vacuum chamber, start the suction switch, suck the air in the vacuum chamber clean, and after the plastic sheet cools down, you can get the same concave packaging or process mold as the mold.

4. Blister packaging and finishing; trim the produced products, that is, the finished product, which can be sold after packaging.

Many manufacturers do not pay attention to the production process of products when producing blister packaging, and do not have strict requirements on quality. The products produced are difficult to meet the needs of customers, resulting in damage to the items in the packaging after customers use the packaging. In fact, blister packaging requires strict molding standards, and products that do not meet the standards are difficult to be recognized by customers. So what are the precautions for the production of large thick plate blister packaging in Shenzhen? Let's analyze it together.

1. During the molding process, there must be strict requirements for the stretching of blister packaging, and the stretching degree of the product should be adjusted according to the molding equipment.

2. The specifications and dimensions do not meet the requirements, the product precision is high, the error range is large, and the packaged products are easy to shake, leading to accidents. Therefore, manufacturers need to have strict requirements on the size of the product.

3. The wall thickness of the product is not strictly controlled, the thickness of some areas is uneven, and packaging problems are prone to occur during use. The thickness of the material and product should be adjusted during the molding process. 4. Pay attention to product quality, improve the level of design capabilities, and confirm customer needs.
