First, the client nds requests for quotation: means a telephone inquiry, means two fax inquiry, means three rounds Email inquiry, channels four through Internet chat tool inquiry.
Plastic products, customers must provide the length, width, height and thickness of materials ud, color and type (PVC, PET, PS), number of products and production cycles.
Second, the business offer: plastic products with high and low price of the following factors: Plastic products, length, width, height and complexity of the compression molding; the type of materials ud, thickness and color; plastic products after processing process (folding, drilling, aling, etc.), order number and order cycle. Staff will offer samples to customers and a description of the initial offer, final offer will be reported after proofing.
腐图铺子Third, the plastic mold of computer-aided design: basic recognition of the customer after the quote, the request, submitted to physical or plastic sample business, production scheduling department will be asked to design the customer's computer to scan and combined with the physical design of printed materials, to produce plastic products, graphic design
Fourth, the bubble shell mold development and proof: the design draft of computer customer acceptance, production scheduling bad on the complexity of plastic products to decide which way to develop mold (plaster mold, copper mold, aluminum mold), the development cycle 3-5 days. Blister plaster mold proofing proofing to the majority, the steps are: 1. First hand the physical contours of mud paste out of shape; 2. Into a version of machine molding plastic foam shell blank; 3 with with a good plastic special plaster into the blister in the blanks, formed after the plaster dried rough; 4. using electric milling rough plaster and rules of shape processing; 5 handmade and hand polished to add components; 6 will be good all polished plaster parts bonded into a complete cast; 7 and then into the plastic vacuum forming machine to play the full version of the sample; 8 according to product size, hand-trimming, edge, complete all the proofing process. If there is a demand, printing proofing department also will blister samples ud in the paper card, sticker or box with the production, they will print with full digital proofer can be reflected in the actual printing results.
Fifth, make the production mold: after a sample has been recognized by customers, usua
lly under a certain number of production orders. Production scheduling bad on production, the complexity of the vacuum forming mold decide which production: The production of gypsum mold, plastic mold making process similar to the proof, the advantage of short production cycle, the lowest cost, to produce a full-page (60X110cm) Just a day or two molds, plastic products is inadequate rough surface, production molds easily broken, poor durability, depth of not forming a large, complex and high, thick sheet products. Electroplated copper mold, the process is to lay the kind of blister on the surface of sprayed layer of conductive agent, and then plated into the inner cell layer thick copper electroplating process takes 72 hours, and then to be fed to the mold gypsum (increasing hardness), polishing, cheer the eye treatment, electroplated copper mold plastic products production has the advantage of a smooth surface, moderate cost, durability, mold production cycle of disadvantage is long enough to complete the production of precision plastic products. Blister aluminum mold manufacturing, mold making need to u computer design drawings, then u of CNC milling machine, the advantage is the production cycle, moderate, post-mold processing time is short (gas hol
e drilled in the CNC machining work done), plastic Size high precision mold durability, the disadvantage is high cost. As the automatic high speed blister molding forming machine range 66X110cm around, so whether it is cast, mold, or aluminum mold, the mold needs to be individual pieces together, to build size, we call this process make-up, needs fight the fight of aluminum or wood on the holes, after a good fight mold we call the end of full-page mode. For large depth of vacuum forming products, also need to make the mold, the bottom sheet vacuum mold forming the same time, pressure from the top sheet, the sheet stretched evenly to every part, otherwi it will cau local thickness is too thin. Production of the entire production cycle of the mold should be 5 to 7 days.
高考文化常识Sixth, plastic molding production: the u of fully automatic high speed blister forming machine, the basic principle is: Rolls of sheet pulled into the electric oven heated to soften the state, by hot plastic mold and then pulled the top of the mold on the move and vacuum, the softening of the sheet to the mold surface adsorption, while the cooling water to mist spray forming sheet on the surface to harden, forming the sheet and then automatically pulled to the storage bins, pneumatic cutter to shape and not forming par
ate sheet to complete the whole process. Plastic products emerged as the major quality problems mostly occur in this process: 1 blister is not in place, the shape deformation is not the same shape and mold plastic into the product; 2 blister over, is the product too thin; 3 . pull, is the molding product line should not have happened on the mark; 4 of uneven thickness. The issues need to die in Shanghao after commissioning in place, including: sheet ahead of time, heating temperature and time, intensity and duration of vacuum, mold on the whereabouts of the location, time and depth, make-up placing in the mold position, the mold is between plus accessories and more.
Seven, punch processing: compression molding of large format products must punch, with a knife split a single version of the product. The principle is the punch at the end of the platform a large sheet of plastic cutting boards, forming the large format products on the chopping block, and the advance of the cutting die stuck in a single product, through the press up and down movement, finding a single product .

quality of the most important part of every punch with a Packers, but also the quality inspector, good for cutting molding and foam shell, the visual quality inspection, quality inspection should include: 1. whether the required shape, (2) whether there is pull on the blister phenomenon, 3 blister on whether there is a large crystal points and bubbles, 4 whether there is a large scratches, 5 out of the blister edge is smooth, no glitches. In addition to quality inspector, the inspection staff comes every two hours for the entire production process to do a quality inspection, fully guarantee the quality of the passing rate of blister .
