Brief Introduction of Vertical Automatic Charging BMC(DMC) Injection Molding Machine
Jiangsu Qianyiliindependent research and development, production of cutting-edge brand vertical automatic feeding BMC(DMC) injection molding machine, complete models, has developed a vertical T type XRT-BMC standard machine, XRT-BMC-DS skateboard machine, XRT-BMC-2R disc machine; Vertical K type (Vertical clamping, horizontal injection) series XRK-BMC standard machine, XRK-BMC-DS skateboard machine, XRK-BMC-2R disk machine, XRK-HBMC-2M double clamping machine; Horizontal XRW-BMC injection molding machine, etc.· Our vertical automatic feeding BMC(DMC) injection molding machine won the utility model patent certificate issued by the State Intellectual Property Office, patent number: ZL200720113295.9;ZL200920198305.2;ZL200920198304.8 ;ZL201320755294.X;ZL201320755295.4.
Our plasma welding gun head plastic coating dedicated vertical BMC(DMC) disc injection molding machine, especially suitable for the production of BMC (DMC) products with inserts or BMC(DMC) products with high hardness requirements, the invention of the machine has the following advantages compared with traditional injection molding machine:
1, because the hopper one-time feeding 15 kg, each mold according to the parameters set by the computer machine automatic feeding, like ordinary injection molding machine can be continuous production. Add another 15 kilos to the hopper when the material is used up. At the end of the day, perhaps two or three times, greatly eliminating the traditional production process of feeding times, weighing, kneading and so on. Completely solve the problem of manual weighing, manual feeding and other complicated and time-consuming traditional processes. Automation replaces the traditional production process, and the production efficiency is greatly improved.
2, reduce the cost of raw materials manufacturers (such as vacuum cleaner motor bracket raw materials bakelite 20000 yuan/ton, BMC molding plastic 6000-10000 yuan /ton) to save labor costs, improve product quality and ensure the yield.
3, can match different injection systems according to customer requirements for product strength, there are a variety of injection molding systems to choose from (ZDZS automatic feeding plunger type, BMC automatic feeding screw type, HBMC automatic feeding screw plunger compound type) to reduce glass fiber damage, ensure product strength.
4. Due to the development of the times, the main production force in the front line is now dominated by the post-80s (90s). People in this era have no subjective living pressure and work requires decent work. Traditional crafts are dirty, tired and hot, and such working conditions simply cannot keep them. Our vertical automatic feeding BMC(DMC) injection molding machine came out to effectively alleviate the current recruitment problems and staff wages rise. Accelerate the development of enterprises from traditional production technology to automation, modernization and energy-saving technology. BMC Thermosets Monolithic molding compounds made of glass fibers, fillers and polyester unsaturated resins can be injection molded on machines equipped with additional specialized equipment. A piston-type feeder is attached to the barrel to force the feed, which can then be operated in two different ways. A type with a conventional reciprocating screw that pushes the material forward while mixing and heating. This requires a check valve at the end of the screw. Prevent material from flowing back to screw threads because of low viscosity of material. Another way is to use a plunger or piston to press the material into the mold cavity. The plunger is often used for materials containing more than 22% glass fiber by weight, because it has less damage to the fiber and can also obtain higher strength BMC thermoset Plastic injection molded products.
BMC injection molding basic process:
(1)charging, the cylinder must be filled with BMC;(2) mold closing;(3) injection;(4) pressure maintenance, heat preservation curing;(5) mold opening;(6) take parts.

Advantages of BMC materials
1. Excellent size accuracy and size stability, small deformation.
2. Linear expansion coefficient is small.
3. Excellent rigidity and heat resistance.
4. The design of products with large wall thickness variation is feasible and can be formed under low pressure.
5. Excellent mechanical strength, electrical performance and acoustic characteristics.
BMC /SMC series molding compounds are widely used in the following fields:
1. Electrical and electronic components: shells and structural parts of various high and low voltage electrical switches, chemical and mining explosion-proof electrical components, motors, solenoid valves, bus frames, terminal plates, insulating rods, insulators, various specifications of insulating plates, etc.
Second, the automobile industry: automobile shell, bumper, lamp bracket, lamp bowl, trunk and other parts inside and outside the car and functional parts.
III. Instrument industry: instrument frame, instrument shell, joystick, etc.
Civil products: sanitary ware, decorations, dishwasher liner, audio products, etc.
Other aspects: electronic copiers, printing machinery, structural parts of office machinery, electronic computer parts, etc.
BMC is short for glass fiber reinforced unsaturated thermosetting plastics (BulkMoldingCompound), which is a class of reinforced thermosetting plastics currently used in large quantities. BMC has good physical properties, electrical properties and mechanical properties, so it is widely used, such as the production of mechanical parts such as gearbox components, intake pipes, valve covers, bumpers, etc.; in the requirements of earthquake resistance, flame retardant, beautiful, durable aviation, construction, furniture and other aspects have also been widely used; in its traditional electrical field ##, its use is more and more extensive. (2)BMC injection molding equipment in BMC application, due to the addition of glass fiber, so the equipment used and the usual thermosetting plastic injection molding equipment is somewhat different, the use of injection molding machines, plunger and screw can be;1) feeding system Whether it is screw or plunger type, an extrusion feeding device must be attached to force the material into the barrel. 2)Injection molding system. Due to the accurate and constant injection volume of the plunger injection molding machine, the glass fiber is dispersed in the melt with less damage. Therefore, the plunger injection molding machine is used more, but the exhaust is inconvenient. 3)Heating system. In BMC injection molding, it is very important to control the barrel temperature, and there must be a set of control system to control the temperature to ensure that the temperature from the feeding section to the nozzle is optimal. At present, constant temperature water or constant temperature oil is used for heating. Electric heating can also be used. 4)Mold clamping device. Multi-use of mechanical, hydraulic and hydraulic type and so on several kinds of clamping device. 5)Mold. BMC injection mold and the usual thermoplastic, thermosetting injection molding some different, large, serious noise, insulation is not ideal. Now the use of high thermal conductivity, good heat dissipation performance, and insulation of the special BMC injection molding machine on the motor stator plastic, you can not need metal shell protection, do not need to dip the coil insulation. In addition, BMC damping is large, power frequency is high, avoiding the resonance point of noise generated when the motor rotates, BMC plastic motor has no noise, and the production cost is reduced by 31%.
BMC injection molding machine production of plastic motor, to achieve the province, light, static, high. Save: save energy, improve efficiency, ordinary steel plate motor input power of 440 watts, BMC plastic motor input power of 370 watts, BMC plastic motor energy consumption reduced by 15%; so that the production cost has been effectively reduced!
Vertical BMC(DMC) disc injection molding machine for plasma welding torch head plastic coating:
BMC material has excellent mechanical properties, heat resistance, chemical corrosion resistance is mainly BMC shrinkage is low, so in the design of mold cavity size should be changed. (3)BMC injection molding process 1) barrel temperature and mold temperature. During processing, BMC is required to maintain a low viscosity flow state for a long time at the barrel temperature; the general barrel temperature should meet the low limit of BMC. The barrel temperature is generally divided into two or three sections, the lower near the hopper end and the higher near the nozzle end. Generally, the difference is 20-60C, and the mold temperature is generally controlled at 135~185C. 2) Injection pressure. Due to the poor fluidity of BMC, fast curing, complex mold structure, injection pressure should choose a higher pressure, generally 80~16OMPao3) injection speed. The increase of injection speed is helpful to improve the surface quality of plastic parts, shorten the curing time, but it is not conducive to exhaust, and increase the orientation of glass fibers. - Therefore, under the premise of ensuring the surface quality of plastic parts, a lower injection g speed should be used, usually 1.8-3.5m/min.
4) Screw speed and back pressure. If the screw injection molding machine is used, when injecting BMC, the screw damage to the glass fiber is large, in order to minimize the damage of the glass fiber, the screw speed should be selected at a low value, generally 20~5Or/min. According to the viscosity of BMC, it is appropriate to use low back pressure, generally 1.4-2.0MPa. 5)Forming cycle. Due to the different size and complexity of plastic parts, the process time of each stage is also different, the general injection time is 2~20s, and the holding time is 10-20s/mm(thickness).
