Hydraulic SMC Moulding Press for New Energy Automobile
2022-06-08 15:02:13
Hydraulic SMC Moulding Press is widely used, especially in new energy auto parts. It is called SMC new energy auto parts molding hydraulic press. It is a kind of composite material molding machine. Press forming in the mold to produce FRP products. There are four-column type, frame type and other structures to choose from, PLC control, easy operation, adjustable working parameters; equipment temperature, curing time, pressure, speed in line with the process characteristics of materials; oil circuit system is a high-precision plug-in. The logic valve system is installed as the standard, the pipeline configuration is simple and clear, and the pipeline connection method is preferably flanged to prevent oil leakage. The motor, oil pump and pipeline are all fixed according to the standard to achieve the effect of anti-vibration and anti-vibration.
SMC front middle door, SMC bumper, light panel, SMC windshield column, SMC truck driver's cabin roof, front middle section, SMC bumper, SMC mask, air shroud, A-pillar, SMC engine soundproof cover, SMC battery holder Frame, lower body protection cover, SMC fender, SMC fender, instrument panel skeleton, SMC trunk shelf and other components.
Advantages of SMC automobile parts
SMC has high heat distortion temperature, HDT is greater than 200 ℃, so it is suitable for the manufacture of hood, sunroof and trunk lid
SMC parts are weather-resistant and durable, greatly reducing maintenance costs.
SMC parts have good impact resistance, absorbing 5 times the impact force of steel.
SMC material has sound insulation properties and is ideal for making automotive sound insulation parts.
SMC has a pass-through feature suitable for the manufacture of rear cargo doors with embedded integrated antennas.
SMC parts have very flexible design freedom.
Elements of Hydraulic SMC Moulding Press for New Energy Automobile
1. The molding pressure of composite materials varies with the product structure, shape, size and the degree of SMC thickening. Products with simple shapes only need a molding pressure of 25-30Mpa; for products with complex shapes, the molding pressure can reach 140-210Mpa. The higher the degree of SMC thickening, the higher the molding pressure required.
2. The size of the composite material molding pressure is also related to the mold structure. The molding pressure required for the vertical parting structure mold is lower than that of the horizontal parting structure mold. A mold with a smaller fit requires higher pressure than a mold with a larger clearance. Products that require high appearance performance and smoothness require higher molding pressure during molding.
3. Since SMC is a rapid curing system, the rapid closing of the SMC new energy auto parts molding hydraulic press is very important. If the hydraulic press closes too slowly after feeding, pre-cured patching will easily appear on the surface of the product, or there will be a shortage of material, or the size will be too large. While achieving rapid closing, the closing speed of the mold should be carefully adjusted at the end of the stroke of the 1000-ton frame hydraulic press to slow down the closing process and facilitate exhaust.
4. The main equipment for molding composite materials are hydraulic presses and molds. The process is divided into feeding, mold closing, exhaust, curing, demoulding and mold cleaning, etc. If the product has inserts that need to be sealed during molding, the inserts should be placed before feeding. The main control process conditions are pressure, mold temperature and molding time.
According to the needs of the workpiece, hydraulic SMC moulding press for new energy automobile are commonly used in 315 tons, 400 tons, 500 tons, 630 tons, 800 tons, 1000 tons, 1250 tons, 1500 tons, 2000 tons, 2500 tons, 3000 tons, etc. Hydraulic SMC moulding press has the advantages of high work efficiency, short investment return period, high-end configuration, stable work, good durability and high reliability.
