Simple process:

Customer 3D drawings - Mold design and manufacturing - (Sheet Silkscreen) - Blister forming - CNC machining to remove scrap - (hand cut off scrap) - Hand scraping - (grinding, polishing) - (glue bonding) - Packaging Shipping.

 

Detailed process:

 1. the customer issued a request for inquiry: a way to call the inquiry, the way two fax inquiry, the way three e-mail inquiry, way four through the network chat tool inquiry. (ABS, PVC, PET, PS, PP, etc.), the number of products and the number of products (or weight), color and type (ABS, PVC, PET, PS, PP, etc.), the number of products and / Production cycle;

2.the business sector offer: plastic products priced at the level of the following factors: plastic products, long, wide, high and the complexity of plastic molding; the type of material used, thickness and color; Processing technology (CNC engraving, scraping, polishing, viscose, etc.), order quantity and order cycle. Engineers (the clerk will slowly learn to quote) will be the customer's sample and description of an initial offer, the final offer will be reported after the proof;

3.product design: customer basic acceptance for the offer, the product will be 3D drawings or physical samples (Division I is not free to the customer design drawings, design drawings to be paid);

4. 1: thick film blister proofing: general (90%) will be directly open aluminum mold proofing, if the product is too large, will first open the wood mold, to be approved after the customer samples and then open aluminum mold; Mold production, mold production need to use computer design drawings, and then use CNC milling machine processing, the advantages of moderate production cycle, the latter part of the mold processing time is short (drilling eye work done in CNC machining), plastic products, high dimensional accuracy, mold Durability is high, the disadvantage is high cost;

4. 2: Blister proofing: The engineering department will decide which way to develop the mold (gypsum mold, copper mold, aluminum mold) according to the complexity of the blister product, and the development period is 3-5 days. Blister proofing to gypsum mold proofing the majority of its operation steps are: 1. First in-kind with a handmade mud out of the contours; 2 into the plastic plate machine molding foam shells; 3. With a good blister Special gypsum into the blister embryo, air-dried after the formation of gypsum embryo; 4.The use of electric milling machine on the plaster and regular shape of the deep processing; 5. Hand-polished and manually add parts; 6. Each polished gypsum parts Adhesive into a complete gypsum mold; 7. and then into the plastic machine to form a complete sample; 8. According to the finished product size, hand-cut, edge, complete all proofing process. If there is a demand, the print proofing department will also produce the paper card, sticker or color box used in the plastic sample, and they will reflect the actual printing result with the full print digital proofing function;

5.1: thick film blister production mold: the sample is approved by the customer, the production of aluminum samples can produce large quantities of goods; if not recognized, the project will be modification (modified mold), until the sample by the customer accept;

5.2: sheet blister production production mold: the sample is recognized by the customer, usually under a certain number of production orders. Engineering Department will be based on the production, the complexity of the formation of the mold to determine which mold production: the use of gypsum mold production, mold production process similar to blister proofing, the advantage is short production cycle, the lowest cost, the production of a full version (60X110cm) Only one to two days time, the shortcomings of the finished product is rough surface rough, the production of mold easily broken, poor durability can not shape the depth of large, high complexity, thick sheet products. The use of electroplating copper mold, the process is to play a good shell surface sprayed with a layer of conductive agent, and then into the electrolytic tank with a thick copper layer, plating process takes 72 hours, then the copper mold to irrigation Gypsum (increase hardness), polishing, eye treatment, the use of electroplating copper mold production is the advantage of smooth plastic products, the cost is moderate, the durability is moderate, the disadvantage is the mold production cycle is long, can not complete the production of precision plastic products. The use of plastic aluminum mold production, mold production need to use computer design drawings, and then use CNC milling machine processing, the advantages of moderate production cycle, the latter part of the mold processing time is short (drilling eye work done in CNC machining), plastic product size High precision, mold durability, the disadvantage is the high cost. As the automatic high-speed plastic molding machine molding range is 66X110cm or so, so whether it is gypsum mold, copper mold or aluminum mold, need to fight together a single mold to achieve the size of the molding, we call this process for the imposition, need Fight in the stamping of the aluminum plate or wood, spell the full version of the mold we call the bottom mold. For products with large plastic forming depth, it is also necessary to make the upper mold. At the same time, the pressure is applied from above the sheet, and the sheet is evenly stretched to each part. Otherwise, Thickness is too thin. The entire production cycle of the production mold should be 5 to 7 days;

6.1: thick film plastic molding production: the use of semi-automatic thick film plastic machine production, the basic principles please refer to the following five point of the plastic molding process; plastic products, the main quality problems in most of the process occurred: 1 . Blister is not in place, refers to the shape of deformation, there is no plastic into the same shape with the mold of the product; 2. Blister, refers to the product is too thin; 3. Pull line, refers to the molding products should not have wire marks ; 4. uneven thickness. These problems are required in the good mold, the commissioning in place, including: the time the sheet forward, the temperature and time of heating, vacuum strength and time, the location of the mold position, time and depth, the mold placed in the mold Position, whether the annex between the mold and so on;

6.2: sheet plastic molding production: the use of automatic high-speed plastic molding machine production, the basic principle is: into the volume of the sheet into the oven heated to softened state, by heat and then pulled to the top of the plastic mold, mold And the evacuated sheet is attracted to the surface of the mold while the cooling water is sprayed onto the surface of the formed sheet in a mist to harden the formed sheet and then automatically pulled to the storage tank. Forming and unformed sheet separation, thus completing the whole process. Often the problem is the same as thick film blistering;

7.1: thick sheet after the plastic processing: Please refer to the following seven "CNC processing and other processing related knowledge";

7.2: sheet blister punch processing: plastic molding of large-format products must go through the punch, with a knife cut into a single product. The principle is in the punch on the bottom of the table there is a large plastic cutting board, the large-format products on the cutting board, and do a good job in advance of a knife in a single product, through the punch up and down movement, cut a single finished , But the shortcomings of this cutting method is that the cutting board and knife mold is easier to damage, resulting in trimming is not smooth, with burr, for the high quality requirements of the blister, you need to use a cold die (a male model, a master mold) And cold press processing.
