Blister packaging processing flow by Hangzhou Oubeier Plastic Industry Co., Ltd
First. The customer issues an inquiry request:
Second. The business department quotation:
The price of blister products is related to the following factors: the length, width, height of the blister products and the complexity of the blister molding; the type, thickness, material and color of the materials used; the subsequent processing technology of the blister products (folding, Punching, edge banding, etc.), order quantity and order cycle, the quotation staff will have a preliminary quotation based on the customer's samples or drawings and description, and the final quotation will be reported after proofing. (Some experienced masters can quote accurate prices before proofing)
Third. Computer design:
After quoting the basic population, the customer will send the request, physical or blister samples to the business department, and the production scheduling will ask the computer design department to scan the customer's physical objects and combine the design of the printed matter to make a graphic design of the blister product.
Forth. Blister proofing:
After the customer approves the computer design draft, the production schedule will decide which way to develop the mold (gypsum mold, copper mold, aluminum mold) based on the complexity of the blister product. The development cycle is 3 to 5 days. (Most of the blister proofing has been proofed by gypsum mold) The steps are:
Fifth, Make production molds:
After the sample is recognized by the customer, a certain number of orders are usually placed
Production scheduling will decide which type of mold is mass produced according to the output and the complexity of blister molding;
Because the molding range of the automatic high-speed plastic molding machine is (about 66 * 110cm), whether it is a plaster mold, a copper mold, or an aluminum mold, a single mold needs to be put together to reach the molding size, we call this process as After the puzzle is assembled, the whole mold is called the bottom mold.
Sixth, blister molding production: the use of automatic high-speed blister molding machine production, the basic principle is: the coiled sheet is pulled into the electric furnace oven and heated to a softened state, said hot and then pulled above the mold, the mold is moved up and pumped Vacuum will absorb the softened sheet to the surface of the mold, and at the same time, the cooling water will be sprayed on the surface of the formed sheet to harden it, and the formed sheet will be automatically pulled to the storage box. Pneumatic cutters separate formed and unformed sheets. Thus completing the process.
Most of the main quality problems of blister products occur during this process:
Seventh. Punch processing: The large-format plastic products must pass through the punching machine and be divided into a single product with a block board. The principle is that there is a large plastic chopping board on the punching machine, and the large-format plastic molded products are placed on the cutting board. And the previously made knife die is stuck on a single product, and the single finished product is cut out by the up and down movement of the punch.
How to calculate the price of blister product, the determinant of the price of blister product. Even a cost of blister egg tray can be calculate.
Unit price of blister = product material cost + energy consumption + labor and transportation + profit
Energy consumption: Blister is processed by heat, and the power consumption is larger than other industries, roughly 8% of the product material cost
Labor: Plastic blister is mainly produced by machines, with less labor, roughly 10% of product material cost
Transportation: According to the distance between the customer and the factory,
Profit: The net profit of the blister factory is generally very low, 12% -20%, depending on the payment period, the 30-day checkout is 14%
Material cost: The calculation of product material cost is more complicated. Before calculating, first make clear the following data:
Raw material price: According to the use of the product, determine what kind of material and grade of material is used, and find the lowest price supplier of this kind of material
Film thickness: It is presumed that the product must be made of thick film, according to the thickness and shape of each part of the molding
Number of layouts: According to the product size and shape, calculate how many molds can be arranged in one version.
Material loss rate: The main factors are the product shape, product quantity and external dimensions and the degree of adaptation of the suction machine chassis.
Material cost calculation formula:
Product material cost = 1 ton raw material price / 1 ton raw material production quantity
The number of finished products per ton of raw material = 1 ton of raw material length / length of blister template X typesetting quantity X (100% —material loss rate)
1 ton raw material length = 1 ton / material density / film thickness / width (width of plastic chassis)
Among them, material density (PVC is 1.36T / M3), blister chassis width (0.41-0.71M), template length and other four parameters are estimated by professional experience.
