1. Mold production
According to the customer's original drawing, requirements or sample, do the product effect drawing first, after customer approval, formal order production. After ① numerical control programming ② by digital control machine to complete the carving ③ heat treatment ④ wire cutting ⑤ mold assembly
Mold species
(1) Stamping die (punching and shearing die, bending die, drawing die, shaping die)
(2) Forging die (upper and lower die, embossing die)
(3) Composite die (forging and stamping together with several processes)
Die casting mold (plane mold, three-dimensional mold, core pulling mold, license plate frame mold)
In addition to the mold itself, it also needs the mold base, mold frame, mold core, feeding device, and the ejection device of the parts everywhere. These parts are also called manipulators. They are generally made general purpose or computer controlled.
2, metal stamping processing
Metal stamping process is to rely on press, hydraulic press, forging press and die to plate, strip (copper sheet, brass sheet, cold tie iron sheet, aluminum sheet) to exert external force, so as to produce plastic deformation or separation, so as to obtain the desired shape and size of semi-finished products. Stamping finished products is the first process flow, lines, letters, patterns must be clear and complete, accurate size.
3, die casting
Die casting is a process in which molten metal is filled with mold under high pressure and high speed, crystallized and solidified to form products. The die casting process is a process in which the three elements of die casting machine, die casting die and zinc alloy are organically combined and comprehensively applied. To make qualified products, it is necessary to unify the process factors such as pressure, speed, temperature and time, plus the selection of high-quality materials and the design of advanced molds. Die casting products in addition to lines, letters, patterns must be clear and complete, accurate size, but also can not have water lines.
4, laser cutting
Laser cutting is the use of aggregated high power density laser beam irradiation workpiece, so that the irradiated material rapidly melting, ablation or reach the ignition point, and with the help of coaxial beam of high-speed air blowing molten material, so as to achieve the product cut out.
5, batch of front
Batch front is due to the production process of the pursuit of products without water grain, increase the pressure and mold surface anastomosing and other reasons caused by, in addition to batch front general use of high-speed drilling machine installed special milling cutter and the use of file. In addition to the batch, the finished product is more beautiful.
6, welding and pot needle
Welding needles and pot needles are made to wear badges, welding needles are fire welding, tin welding, silver welding, brazing and glue. The pot needle is then die-cast on the pin through a drill press die.
7, metal polishing
Metal Polishing is the use of machinery, polishing wheel, polishing wax to make the surface of the product bright. For products of different materials (sand, soft, hard, linen wheel, soft and hard cloth wheel) different polishing wax. The product after polishing not only has brightness, no pitting, but also should not be deformed.
8, electroplating
Electroplating is a process of plating a customer specified metal on the surface of a product using the principle of electrolysis. During electroplating, the coating metal and insoluble solution do the anode, the product to be plated as the cathode, the cation of the coating metal deposited on the surface to be plated to form a coating, so that the product is more bright, beautiful and improve the wear resistance of the product and prevent product oxidation. Qualified electroplating products must have no bubbles, no pitting.
9, paint
Spray paint process is the product to be spray painted after oil removal, paint removal, phosphating, drying, in accordance with the customer requirements of color, product quality spray paint. In operation, first spray primer, dry, and then spray finish, bake to death.
10, coloring
Coloring is the most important process to do handicraft factory, and it is the most important process to determine the quality of a product.
(1) Enamel (cloisonne basket), the bottom tire is forged with copper plate, enamel powder is the mineral silicon, lead Dan, borate, feldspar, quartz and other raw materials in proportion to mix. Each kind of colored metal oxide is added, and the powder is made by roasting and grinding. When used, the enamel powder is selected according to the special color card. After grinding, the enamel powder is washed in pure water and dried on the clean bottom tire with a flat head iron needle, and sintered at high temperature. After cooling, sulfuric acid, water, dry again on another color, and then sintering. After all the colors are sintered, the stone is grinded, coarse grinding followed by fine grinding, and then the product is repaired. The final sintering determines the level and brightness of the enamel surface. After the process is polishing and electric crossing.
(2) False enamel (imitation enamel) bottom tire: copper plate, brass plate, cold rolled plate, zinc alloy, etc. The false enamel color paste is made by grinding epoxy resin and color powder. When using, after color mixing according to the color card, add hardener in proportion, dry it on the cleaned and heated bottom tire with a needle cylinder, and then apply another color. After all colors are applied, polish it with 240 # sand belt wheel. The hardness of epoxy resin, polishing wheel and wax determine the brightness of product surface.
(3) The paint process is to color the products that have been electroplated. Paint we choose propylene acid high temperature paint, so that the product does not change color for a long time. After mixing the color, the needle is used to put it on the product. At present, there are coloring machines on the market, and large orders can be considered to use. Generally, after finishing a color, wipe it with a clean cloth once. After coloring, wipe clean and bake to death. Often some customers require good electroplated products on the false enamel paste. At the price of baking paint, we received fake enamel.
(4) Printing badges (plate printing, screen printing), generally make 0.6mm-0.8mm stainless iron plate and brass plate, the surface can be electroplated, can also be natural color or drawing sealing oil treatment. Flat plate printing is especially suitable for scenic badges with complex patterns, many colors and gradients. Screen printing mainly for guests to request special color, simple pattern of badges, number plates. Printed badges out of the general use of glue with a needle and anti-burr drop a layer of glue.
(5) , bite the plate badge, the designed badge drawing film negative, through the plate exposure, the negative of the badge drawing is transferred to the copper plate, and then use chemical agents in the special machine to corrosion out the pattern, and then color, grinding plate polishing, punching, welding needle, electroplating, glue drops.
11, screen printing processing
Screen printing processing (different from screen printing badges) is to overprint letters or patterns on the fake enamel, flat metal, and drip surface according to the customer's requirements.
12, Rhinestones
Rhinestones of different colors, quality and size are added to the products to add icing on the cake, to enhance the highlights of the products. Qualified products rhinestones should be clean and tidy, in order to be beautiful and generous.
13, glue
Gum drops, also called gaboli, plus resin. Drop a layer of glue on the surface of the product, either naturally dry or heated to dry. To protect the surface of the product and make the product more beautiful.
14，Car ribbon
The ribbon is the connection between the medal and the ribbon. It needs to be done manually on an electric clothing cart. All ribboned MEDALS should be covered with protective film.
15, installation
Installation is to put the finished product on the accessories and assemble several products together, must wear a finger sleeve and prevent touching the product.
16, packaging
Packaging IS according to the requirements of the customer to pack the product, wearing butterfly hat, paper card, into plastic bags or bubble bags and then into the bag, or in the box. Then put them in outer boxes and make good packing straps. Not more than 12kg per box shall prevail.
17, quality inspection
Quality inspection A department that must be established to ensure the quality of products. Wanjun factory department has a full-time quality supervisor, responsible for the first product confirmation work and guide the daily work of each workshop. Stamping, die casting, polishing, plating, packaging and other workshop products full inspection. Conduct inspection of individual products and spot check after finished product packaging to ensure the quality of products.
