First, the client sends a request for quotation: a way to call the inquiry, two ways to send a fax inquiry, three ways to send Email Inquiry, pathways through the Internet chat tool inquiry four. Customers must provide plastic products of the length, width, height and thickness of the material used (or weight), color and type (PVC, PET, PS, PP), the number of products and production cycle.
Second, the business sector offer: plastic products unit price level with the following factors: length, width and height of the complexity of the plastic products and plastic molding; the type of materials used, thickness and color; plastic products after processing process (folding, punching, sealing, etc.), the order quantity and order cycle. Members will offer customers samples and there is a description of the initial offer, final offer will be reported after proofing.
Third, computer design: customer offer basic recognition for later, it will be sought, physical or plastic samples submitted to the business unit, production scheduling will require a computer design department will scan the customer's physical and combined with print design, produce plastic products the graphic design
Fourth, Blister proofing: customer acceptance draft of computer design, the production scheduling will be determined according to the complexity of the plastic products which way the development of mold (plaster mold, copper mold, aluminum mold), the development cycle of 3-5 days. Plastic proofing plaster mold proofing majority, the steps are: 1. First kind handmade clay paste with a forming contour; 2 onto the plastic making machine blister molding blanks; 3 with the formulated plastic. special plaster into the bubble shell blanks, and air-dried form gypsum blank; 4. the use of electric milling gypsum blanks and rules shape for further processing; 5. polished by hand and manually add components; 6. various polishing good plaster components will bonded into a complete plaster mold; 7. then put plastic making machine plastic molding complete sample; 8. press the finished size, hand-trimming, edge banding, complete all the proofing process. If there is demand, printing proofing department will blister sample paper cards simultaneously used, stickers or color box with the production and printing of digital proofer can print the results of their actual aid will be reflected in full.
Fifth, making the production mold: after the sample has been recognized by customers, usually a certain number of production orders. Production scheduling will be determined according to the complexity of the production, which uses plastic molding mold production: the plaster mold production, mold production process similar to plastic proofing, the advantage of short production cycle, the lowest cost to produce a full-page (60X110cm) die just a day or two, the downside is that plastic finished surface roughness, the production mold shatter easily, poor durability can not be molded depth, complexity is high, the sheet thickness of the product. Electroplated copper mold, the process is to lay the kind of blister surface sprayed with a conductive agent, and then into the electrolyzer coated with a thick layer of copper plating process takes 72 hours, and then on the copper mold to carry out irrigation gypsum (hardness increase), polishing, cheer eye treatment, the advantages of using electroplating copper mold production is a smooth surface plastic products, moderate cost, durability, moderate, mold disadvantage is a long production cycle, unable to complete the production of precision plastic products. Blister aluminum mold production, mold making first use of computer design drawings need, then using the CNC milling machine, the advantage is moderate production cycle, post-mold processing time is short (drill gas hole is completed when the CNC machining), plastic products size high precision, the mold durability, the disadvantage is the high cost. Due to the range of high-speed automatic molding plastic molding machine it is about 66X110cm, so whether it is cast, copper mold or aluminum mold needs a single mold pieces together to achieve the molding size, we call this process Imposition need fight on lay pores aluminum or wood, after a good fight full-page mold we call the bottom die. For large depth of plastic molding products, but also on the need to make a mold, in the bottom mold sheet vacuum forming, while applying pressure from the top of the sheet, the sheet evenly stretched to every part, otherwise it will cause local too thin. The entire production cycle of the production molds should be 5-7 days.
Sixth, plastic molding production: the use of high-speed automatic plastic molding machine production, the basic principle is: Rolls of sheet pull into the electric furnace is heated to soften the state of the oven, take the heat and then pulled over the plastic mold, mold on the move and evacuated, the softened sheet adsorbed to the surface of the mold, while cooling water was sprayed on the surface of the sheet molded, cured, molded sheet and then automatically pulled to the storage silo, pneumatically molding the cutter No separation of the formed sheet, thus completing the whole process. Most plastic products quality problems arise mainly occur in this process: 1 Plastic in place, it refers to the shape deformation, not plastic into the same shape and mold products; plastic over 2, refers to the product too thin; 3. . Pull refers to undue line marks appear on the molded products; 4. uneven thickness. These issues need after Shanghao mold, debugging in place, including: time sheet forward, heating temperature and time, the vacuum strength and time, the upper die the whereabouts of location, time and depth in the mold placed imposition location, whether to raise between mold accessories and so on.
Seven Punch processing: large format plastic molding products must undergo punch, split with a knife version into a single product. The principle is in the punch at the end stage with a large sheet of plastic cutting boards, the large format molding products on the chopping block, and well in advance of the cutting die on the card in a single product, up and down movement of the punch, cutting out single finished , but the downside of this approach is that cutting cutting board and knife mold relatively easily damaged, resulting in cutting edge is not smooth, burr, high quality requirements of the blister, need die (a male mold, a master mold) processing and cold punch.
