Sheet Molding Compound (SMC) machinery makes SMC. It is a high-strength, glass fiber-reinforced polyester for compression molding. The SMC process uses machines to prepare SMC sheets and mold final parts. SMC equipment supports high-volume production with short production cycles. It takes 1 to 5 minutes to produce each part, depending on its size and thickness. The machinery can make products with complex shapes. They will have high dimensional stability and strong repeatability. We can optimize the SMC formulation by adjusting the fiber, fillers, and additives. The products have an extremely high surface finish.
Application Of SMC Product
SMC makes fiberglass products, water tanks, meter boxes, trash bins, cable supports, cable ducts, automotive parts, septic tanks, and resin drainage covers.
The Machinery Features
- The machine’s control system has manual and semi-automatic working modes.
- The hydraulic system uses a two-way cartridge valve. The electrical system uses PLC control.
- The machine’s power system is on the ground. This makes maintenance easy.
- An independent, movable control cabinet equips the machine for easy operation.
- The machine can limit pressure, travel, position, and perform process actions.
The Machinery Body
The body comprises an upper beam, lower beam, slider, columns, and nuts. The upper and lower beams are firmly connected with four columns and nuts, forming a rigid frame. The columns guide the slider and move up and down along them. The slider’s guide sleeves have dust rings. They stop dust from scratching the column. T-slots (specific dimensions proposed by the user) are opened on the slide and lower beams. The column nuts can adjust the worktable’s unevenness and angle to the piston. Large parts are precision processed using large CNC floor-type boring and milling machines. We also use high-precision CNC gantry planning and milling machines. A computer and finite element analysis optimized the three-beam, four-column structure. It has high strength and a sleek look.
Cylinder
The main cylinder adopts a piston cylinder structure, fixed in the center hole of the upper beam by bolts. The cylinder body is rolled. The piston rod is quenched and tempered. It is hard chrome-plated and polished for wear, beauty, and corrosion resistance. The piston rod and guide sleeve use composite materials. They are wear-resistant, stable, and reliable.
Hydraulic System
The machine uses an electro-hydraulic servo drive system, which has the following advantages:
- Energy-saving: The electro-hydraulic servo-driven press is much more efficient than traditional hydraulic machines. The servo-driven hydraulic press can save 20%–60% of electricity. The savings depend on the processing technology and production speed.
- Low noise: This electro-hydraulic press has a low-noise oil pump. Traditional hydraulic presses generally use axial piston pumps. The low-noise pump is 5 dB to 10 dB quieter than the axial piston pump at the same flow and pressure.
- Less heat generation: It reduces cooling costs and hydraulic oil costs. The servo-driven hydraulic press’s hydraulic system does not generate heat from overflow. With the slider stationary, there is no flow. Thus, there is no heat from hydraulic resistance. Its hydraulic system generates 10%–30% of the heat of traditional machines.
- High efficiency: Properly controlling speed can significantly speed up the servo-controlled hydraulic press. It can also optimize energy use. Its work rhythm is 10-15 cycles per minute. That’s several times faster than traditional hydraulic machines.
- High control accuracy: The servo oil pump’s pressure control link is a closed loop. A pressure sensor measures the system pressure. Oil temperature or viscosity does not affect the pressure. This ensures high accuracy and repeatability in pressure control, improving product quality.
- Easy maintenance.
