BMC is what materials and what purpose it? BMC injection molding machine how?

The so-called BMC (DMC) is a material Bulk (Dough) molding compounds acronym, that dough molding compound. China is often called unsaturated polyester bulk molding compound. The main raw materials from GF (chopped glass fiber), UP (unsaturated resin), MD (filler) and various additives sufficiently mixing of dough-like prepreg. Because BMC bulk molding compound with excellent electrical properties, mechanical properties, heat resistance, chemical resistance, and to adapt to a variety of molding processes, a variety of products to meet performance requirements, so more and more customers favorite.
Applications BMC / DMC's
1, BMC Injection Molding Machine Automotive Industry
A lamp reflector (reflector lamp requires high temperature and dimensional stability)
B hood and other large parts, the rear doors, electric boxes, hood, speaker boxes, electric headlight housing and sub-prime.
2 BMC injection molding machine precision components
No fuse circuit breaker housing, motor housing, etc., gramophones speakers, tape cassette components, copiers, fax machines, printers, medical equipment, measuring instruments.
3 BMC injection molding machine electrical components
BMC is already unsaturated polyester resin matrix, its electrical properties, flame retardancy are superior phenolic molding plastic, thus increasing the range of applications in the electrical industry.
A high-pressure part TV socket shell, flyback transformers, wiring board, the channel selection knob, octagonal plugs, bobbin discharger and the like.
B wiring member breakers, distribution boards, knife opening units, fuse boxes and terminal boxes tube.
C high-voltage devices, vacuum circuit breaker enclosures, baffles, insulators, insulation panels.
D welding clamp.
E Other breaker base, micro-switches, coil bobbins and the like.
4 BMC injection molding machine parts coil enclosed
BMC molding method using electrical components substituted dipping insulating treatment and a housing complex installation process Electrical treatment (such as tie wire motor, dipping treatment and drying processes)
5 BMC injection molding machine for daily use such as microwave dishes, iron shell.
    Now we have contacted BMC (DMC) products are generally automatic feeding by a hydraulic press or BMC BMC BMC injection molding machine production from the two devices, so-called BMC hydraulic machine, said this model mainly rely on artificial feeding, hand feeding plastic to complete production processes dirty, tired and hot, and if the BMC material accidentally touches the body would itch, a long time will have to occupational diseases. Another automatic feeding BMC injection molding machine is especially suitable for the production of inserts with BMC products or products that require high hardness of BMC products, BMC abandoned the original hydraulic machine will call each mold material rub drawbacks, now as long as direct fill material in the series dedicated machine (15 kg) can be as common as hot presses, continuous normal production, save raw material and very environmentally friendly, labor intensity is greatly reduced. Traditional craft when taking product temperature is relatively high, you must use gloves when handling, process measurement feedstocks will pick up residual material on the glove, so that the product will stick to the impact of product appearance, the most serious is the BMC raw materials containing a large number of glass fibers harmful to human skin, itching, and even lead to occupational disease!
