For the thermoforming industry, whether it is material, mold or equipment is very important, such as large-scale thermoforming, in addition to selecting high-quality materials and suitable molds, it is also necessary to prepare a large-scale thermoforming machine that meets the requirements.
The large-scale thermoforming machine is suitable for ABS, PP, PS, PVC, EPS, PET, PETG, HIPS, acrylic and other thick thermoplastic sheets. Pieces, household, electrical appliances, door panels, lighting, luggage, decorative parts, furniture, sanitary ware, lamps, toys, teaching, equipment, art advertising, traffic signs, trays and other products Thick sheet thermoforming products can not only replace injection molding, save the cost of expensive injection molds, but also replace traditional hand-made products, and have the advantages of advanced production technology, high speed and reliable quality.
Thick Sheet ThermoformingMaterial/ Product Show
Thick sheet thermoforming molds are the basic process equipment for mechanical industry production and an indispensable tool in the production of industrial products. The performance of molds made of mold steel needs to be supervised by strict production processes, and the raw materials for mold production must also pass through. Strictly check to prevent the mold from forming defects such as heat treatment cracking and early failure due to material problems. The thick sheet plastic mold factory has an independent mold library. The molds have various specifications due to different shapes and sizes. If you want the molds to be neatly arranged, the mold library will be placed on the shelf and aligned, and then the molds will be placed on the shelf. Each mold There are corresponding numbers, easy to find.
After the thick sheet thermoformed samples are approved by the customer, a certain number of production orders are usually placed. Production scheduling will decide which mold to use for mass production according to the output and the complexity of thick sheet blister molding
- It is produced by plaster mold. The mold making process is similar to blister proofing. The advantage is that the production cycle is short and the cost is low. It only takes one to two days to make a full-plate (60X110cm) mold. The disadvantage is that the thick sheet thermoforming finished product The surface is rough, the mold is easily broken during production, and the durability is poor, and it is impossible to form products with large depths, high complexity and thick sheets. The electroplating copper mold is used. The process is to spray a layer of conductive agent on the surface of the prepared bubble shell, and then put it into the electrolytic cell to coat a thick copper layer. The electroplating process takes 72 hours, and then the copper mold is poured. Gypsum (increasing hardness), polishing, and air-pumping treatment. The advantages of using electroplated copper molds are that the surface of thick-sheet plastic products is smooth, the cost is moderate, and the durability is moderate. The disadvantage is that the mold production cycle is long, and precision thick-sheet plastic products cannot be completed. production
- It is produced by plastic plastic aluminum mold. The mold production needs to use computer design drawings first, and then use CNC numerical control milling machine to process. The advantages are that the production cycle is moderate, and the later mold processing time is short (drilling holes are completed during CNC processing), and the size of plastic products is High precision, strong mold durability, the disadvantage is high cost. Since the molding range of the automatic high-speed plastic forming machine is about 66X110cm, whether it is a plaster mold, a copper mold or an aluminum mold, it is necessary to put together a single mold to reach the molding size. It is spliced on the aluminum plate or wooden board with holes, and the finished die is called the bottom die. For products with a large depth of thick sheet blister molding, it is also necessary to make an upper mold. While the bottom mold is vacuuming the sheet, apply pressure from above the sheet to stretch the sheet evenly to each part, otherwise it will Causes the local thickness to be too thin. The entire production cycle for the production mold should be 5 to 7 days
