After the customer approves the computer design draft, the production scheduling will decide which method to use to develop the mold (plaster mold, copper mold, aluminum mold) according to the complexity of the blister product. The development cycle is 3-5 days.
The blister proofing is mostly plaster mold proofing. The operation steps are as follows:
1. First, use manual mud to form the outline of the actual object;
2. Put it on the blister making machine to form the blister embryo;
3. Pour the prepared blister-specific gypsum into the blister embryo and form a gypsum embryo after air-drying;
4. The electric milling machine is used for deep processing of gypsum rough and regular shapes;
5. Manual polishing and manual addition of parts;
6. Glue the polished gypsum parts into a complete plaster mold;
7. Then put it into the blister plate making machine to blister and form a complete sample;
8. According to the size of the finished product, manually trim and seal the edges to complete the entire proofing process. If there is a demand, the printing and proofing department will also make the paper cards, stickers or color boxes used for the blister samples at the same time, and they will use the full-open printing digital proofing machine to reflect the actual printing results.
Making blister production molds:
After the sample is approved by the customer, a certain number of production orders are usually placed.
The production scheduling will decide which mold to use for mass production according to the output and the complexity of the blister molding:
1. It is produced by plaster molds. The mold making process is similar to blister proofing. The advantage is that the production cycle is short and the cost is the lowest. It only takes one to two days to make a full-page (60X110cm) mold. The disadvantage is that the surface of the blister product is rough. , The mold is easy to break during the production, and the durability is poor, and the products with large depth, high complexity and thick sheet cannot be formed.
2. Using the "target=_blank> electroplating copper mold, the process is to spray a layer of conductive agent on the surface of the blister shell, and then put it into the electrolytic tank to plate a thick copper layer. The electroplating process takes 72 hours. Next, the copper mold should be filled with plaster (increase the hardness), polished, and blow-up treatment. The advantages of using electroplated copper molds are that the surface of the blister product is smooth, the cost is moderate, and the durability is strong. The disadvantage is that the mold production cycle is long and the precision cannot be completed. Production of blister products.
