Materials for thermoforming mostly thermoplastic material. Whether single or multi-layer composite plastic sheet (board) material must meet the following process performance for thermal forming 1: The plastic memory 2: Hot Stretch 3: Hot Strength 4: molding temperature of thermoformed plastic commonly used: a PVC (feature is that impurities teach less, transparency is better, than the end price, with good dielectric properties, flame retardant and self-extinguishing) II PP (rich source of cheap, high-performance, versatile. 1, low density (PP colorless, odorless, tasteless, non-toxic, flammable, look for white density of 0.90 ~ 0.91g / cm 3.) 2, good mechanical properties PP rigid extension particularly good, good stress cracking resistance 3, heat resistance teach 4, 5 good chemical stability, transparency, water waterproof 6, molding, and the use of strong three PE (one of the largest output, the most widely used plastic varieties, odorless, tasteless, non-toxic, flammable) Four PS (plastic, hard, brittle, transparent, there is no smell, burning black smoke, easy to dyeing and processing, low moisture absorption, dimensional stability, electrical insulation and thermal insulation.) 1, 2 transparency and gloss, coloring, health excellent performance 3, 4 excellent dielectric properties, excellent formability less: 1, 2 brittle, heat resistance teach poor 3, moisture, oxygen barrier is poor five ABS (non-transparent, non-toxic, tasteless) Six PET (colorless, odorless, tasteless, non-toxic, good transparency, excellent mechanical strength, abrasion resistance and electrical insulation properties, good creep resistance, stiffness and strength of good health it can direct contact with food) basic methods of molding plastic heat thermoforming many ways, according to the molding power molding and differential pressure can be divided into two categories molding according to mold, it can be divided into single male, single female mold to mold, no mold, several methods known as compression molding machine stretch forming, is the use of single-mode or form of the mold by means of external mechanical pressure or weight, the plastic sheet is made of plastic each The method of forming the seed article. The shape of the male die means are convex die, die means are concave shape of the mold, the mold the molded article only one side, the other side exposed to the air, which is different from a molding process of press molding. This method can be adapted to all basic thermoplastics. a single male molding single male molding, also known as punch forming or bent shape, vertical shape. It is heated and softened plastic sheet to borrow machinery to shape the The method of forming a certain shape. Two single-die molding, also known as single female forming die molding. Third, the molding of the molding die, male die, die, fixtures and other accessories common components. Fourth, the composite mold on the molded plastic machine [Edit this paragraph] the composition and role of a plastic machine, when the plastic sheet material forming the clamping device, the sheet is fixed to the clamping device. In general thermoforming and composite thermoforming machine easy to use more fixed clamping device of some sheets of various sizes throughout the molding machine with a clamping device a clamping frame can be divided into two categories: one is the frame, and the other is split formula. Frame clamping device consists of upper and lower framework. Sheet sandwiched between two frames. When the frame is opened, the lower frame generally remain fixed state. The lower part of the various types of single-station machine is fixed to the frame directly in the molding chamber. Hand equipment parison and the finished removing manual and semi-automatic machine, when the frame size is large, are equipped within the framework of open-wide security operation device. Slipping property of forming large preforms required clamping force can be adjusted over a relatively wide range, therefore, the use of two packages roller, pressed against each other with a spring, and with a pressure regulating device. Clamping continuous sheet molding machines pull the zipper on both sides of the front and rear brake interaction. Clamp preferably automatically controlled, in order to prompt action, can help to improve part quality and efficiency. Second, the vacuum heating equipment thermoplastic sheet and film forming process, the process is one of the main sheet is heated. Duration and quality of electric heating structure depends on the distance, the surface temperature of the heat transfer after irradiation thermal inertia, the sheet between the heater and the heater, radiant energy absorption coefficient, thermal physical performance characteristics of the heater surface and material. Commonly used heater electric heater, crystal radiator and infrared heaters. Third, the vacuum equipment vacuum system consists of a vacuum pump, tank, valves, pipes and vacuum tables, etc., are often used in vacuum forming a single model vacuum pumps, vacuum pump should reach this degree of 0.07 ~ 0.09 Mpa (520mmHg) above. Gas tank is generally cylindrical with a thin steel plate welded box, the bottom is oval. Storage tank capacity should be at least greater than the capacity of the largest molding chamber half. Vacuum line, must be equipped with appropriate valves to control the vacuum narrow capacity. Rotary vacuum pump power is determined by the size of the molding equipment and molding speed, bigger or faster molding equipment used to 2-4KW of big. Central vacuum system, depending on the size and development of plant specific production requirements. Fourth, the compressed air system by pneumatic machine with its own compressor, tank, workshop supervisor path sets, valves and other components. 0.4-0.5MPa machine needs compressed air pressure, all kinds of vacuum forming machine widely used in piston air compressors. It can also be supplied with a large screw-type air compressor the whole plant. In addition to a large number of compressed air should be in shape, there are used as part of the release, the outer mold cooling and handling framework and operational action sheet and other parts of the power at the beginning of the article. Fifth, the cooling equipment in order to improve production efficiency, before releasing vacuum forming products often require cooling. Ideally, an inner surface and an outer surface in contact with the mold parts are cooled, and the best use of built-in cooling coil mold. For non-metallic mold, such as wood, plaster, glass fiber reinforced plastic, and epoxy resin mold, due to inability to use water-cooled, can switch to air-cooled, and additional water mist to cool the outer surface of the vacuum molded article. Production using natural cooling can be obtained if annealing parts, help to improve the impact resistance of parts. While the high efficiency of cooling with water, but the stress is large parts. Sixth, the release device releasing the product out of the die is usually either die or punch, most cases are due to the contraction snapping mold cooling products, so by vacuum suction hole or in the opposite direction of the hair to make it mold. Especially for a small draft angle of the mold or die while using the release mechanism releasing contradict or shock, sometimes on the sheet and the mold or mold release agent applied surface coating Teflon treatment. Seven control equipment control system generally includes a vacuum forming molding, finishing and other processes including instrumentation, instrumentation, piping, valves, various parameters and motion control.
