How is the whole process of blister molding implemented? How many days does it take to complete blister proofing? What is the principle of blister molding processing? The blister process is divided into the following points:
1. The customer sends an inquiry request: the first way is to call for price inquiry, the second way is to send a fax inquiry, the third way is to send an email inquiry, and the fourth way is to make an inquiry through an online chat tool. Customers must provide the length, width, height, thickness (or weight) of the material used, color and model (PVC, PET, PS, PP), product quantity and production cycle of the blister products.
2. Business department quotation: The unit price of blister products is related to the following factors: the length, width, height and complexity of blister molding; the type, thickness and color of the materials used; the subsequent processing of blister products Process (folding, punching, edge banding, etc.), order quantity and order cycle. The quoter will make an initial quotation based on the customer's sample and description, and the final quotation will be quoted after proofing.
3. Computer design: After the customer has basically approved the quotation, he will hand over the requirements, physical objects or blister samples to the business department. The production schedule will ask the computer design department to scan the customer's physical objects and combine them with the design of the printed matter to produce blister products. Graphic design drawing
4. Blister proofing: After the customer approves the computer design draft, the production schedule will decide which method to use to develop the mold (gypsum mold, copper mold, aluminum mold) based on the complexity of the blister product. The development cycle is 3-5 sky. Blister proofing is mostly based on plaster mold proofing. The steps are: 1. First, use hand mud to paste the actual object into the molding outline; 2. Put it on the blister plate maker to form the blister blank; 3. Use the prepared blister Special gypsum is poured into the bubble shell blank and dried to form a gypsum blank; 4. Use an electric milling machine to deeply process the gypsum blank and regular shapes; 5. Manually polish and manually add components; 6. Polish each polished gypsum component Glue it into a complete plaster mold; 7. Then put it into a blister-making machine to form a complete sample; 8. According to the size of the finished product, manually cut and seal the edges to complete the entire proofing process. If necessary, the printing and proofing department will also produce the paper cards, stickers or color boxes used for the blister samples. They will use a fully-open printing digital proofing machine to reflect the actual printing results.
5. Making production molds: After the sample is approved by the customer, a certain number of production orders will usually be placed. Production scheduling will decide which mold to use for mass production based on the output and the complexity of blister molding: plaster mold production is used. The mold making process is similar to blister proofing. The advantage is that the production cycle is short, the cost is low, and a full version (60X110cm) can be produced. ) The mold only takes one to two days. The disadvantage is that the surface of the blister finished product is rough, the mold is easily broken during production, and the durability is poor and it cannot form products with large depth, high complexity, and thick sheets. Using an electroplated copper mold, the process is to spray a layer of conductive agent on the surface of the ready-made bubble shell, then put it into an electrolytic tank to plate a thick copper layer. The electroplating process takes 72 hours, and then the copper mold is filled. Gypsum (increases hardness), polishing, and punching treatment. The advantages of using electroplated copper molds for production are smooth surface, moderate cost, and moderate durability. The disadvantage is that the mold production cycle is long and the production of precision blister products cannot be completed. Blister aluminum molds are used for production. Mold production requires computer design drawings first, and then CNC milling machine processing. The advantage is that the production cycle is moderate and the post-mold processing time is short (drilling air holes is completed during CNC processing). The size of the blister products It has high precision and strong mold durability, but the disadvantage is high cost. Since the molding range of the fully automatic high-speed blister molding machine is about 66X110cm, whether it is a plaster mold, a copper mold or an aluminum mold, individual molds need to be put together to reach the molding size. We all call this process imposition, which requires It is assembled on the aluminum plate or wooden board with holes punched in it. The whole mold after assembly is called the bottom mold. For products with a large depth of blister molding, an upper mold needs to be made. While the bottom mold vacuum-forms the sheet, pressure is applied from above to stretch the sheet evenly to every part. Otherwise, localized Thickness is too thin. The entire production cycle of the production mold should be 5 to 7 days.
6. Blister molding production: It is produced by a fully automatic high-speed blister molding machine. The basic principle is: pull the rolled sheet into an electric furnace oven and heat it to a softened state, then pull it to the top of the blister mold by heating, and the mold moves upward. And vacuum is drawn to adsorb the softened sheet to the surface of the mold. At the same time, cooling water is sprayed on the surface of the molded sheet in a mist form to harden it. The molded sheet is automatically pulled to the storage box, and the pneumatic cutter will form it. Separate from the unformed sheet to complete the entire process. Most of the main quality problems of blister products occur during this process: 1. Insufficient blister means that the shape is deformed and the product is not blistered into the same shape as the mold; 2. Excessive blister means that the product is too thin; 3. .String refers to the appearance of undue line marks on the molded product; 4. Uneven thickness. These problems all need to be debugged after the mold is installed, including: the time of sheet advancement, the temperature and time of heating, the intensity and time of vacuuming, the position, time and depth of the upper mold falling, and the placement of the mold in the imposition. Location, whether to add accessories between molds, etc.
7. Punch processing: Large-format products formed by blister must be punched and divided into single products with a knife. The principle is that there is a large plastic chopping board on the base of the punch. Place the large-format molded product on the chopping board, and clamp the pre-made die on the single product. Through the up and down movement of the punch, a single finished product is cut out. , but the disadvantage of this cutting method is that the chopping board and the knife die are relatively easy to damage, resulting in uneven cutting edges and burrs. For bubble shells with high quality requirements, a cold punching die (one male die and one female die) is required. and cold punch processing.
