CNC SMC Hydraulic Press Sheet Molding Compounds Product With One Year Warranty

Composite Molding Sheet molding compound machine , SMC Sheet Molding Compounds Product,Fiberglass Compression Molding


Composition


SMC is made as a continuous sheet. The resin paste is transferred to a doctor box where it is deposited onto a moving carrier film passing directly beneath. The doctor box controls the amount of the resin paste applied. Simultaneously, glass fibre rovings are fed into a rotary cutter above the resin-covered carrier film. Fibres are chopped to length (generally 25mm, or 50mm) and randomly deposited onto the resin paste.

The amount of glass is controlled by the cutter and by the speed of the carrier film. Downstream from the chopping operation, a second carrier film is coated with resin paste and is laid, resin side down, on top of the chopped fibres. This stage of the process creates a resin paste and glass fibre ‘sandwich’ which is then sent through a series of compaction rollers where the glass fibres are consolidated with the resinpaste and air is squeezed out of the sheet.Sheet dimensions are normally 4mm thick and 1,500mm wide. The length and weight of the SMC sheet is determined by moulder preference for handling and is usually stored on a 350kg (standard) up to 1500kg rolls or bi-folded (like computer paper) into large bins. Modern SMC production is a highly automated and computer regulated process.


Company composite molding equipment performance characteristics


  1. Nominal force: up to 5000 tons
  2. Countertop: Maximum 5000mm
  3. Slider stroke: up to 4500mm
  4. The slider has a maximum fast return speed: 800mm/S
  5. Slider minimum mold opening speed: 0.1mm/S
  6. Pressure holding accuracy: 0.8MPa/hour per hour (no pressure compensation)
  7. Touch screen plus PLC control system, bus control system
  8. The four-corner leveling system meets the high-precision requirements for large-area thin-walled parts, and the leveling accuracy is ±0.05m.
  9. The hydraulic system uses a piston accumulator, which is 40-60% lower than that of a conventional press.
  10. Complete press mechanical locking safety system and electronic control interlock system.


Company composite molding equipment performance characteristics



LFT-D long fiber reinforced thermoplastic directly inline molding



Main functional unit

1. Glass fiber yarn pretreatment unit: the fiber bundle is dispersed by the yarn dividing device, and the dispersed fiber bundle passes through the yarn guide frame and enters the yarn immersing device. After the immersion agent is infiltrated, it enters the drying device, and is dried and then wound on the package for preparation. Feed into the extruder.
Compounding and extruding unit: The base resin, auxiliary agent, fiber, etc. are mixed and plasticized in a first-order and second-order twin-screw extruder according to a set ratio by a raw material supply and feeding device, and the required size is extruded. band.
2. Insulation conveying unit: The LFT material strip extruded from the screw extruder enters the insulated double conveyor belt device and is to be grabbed by the robot.
Robotic gripping unit: The multi-joint robot is responsible for grabbing and placing the composite material block on the conveyor belt in the press cavity.
3. Press forming unit: After receiving the signal, the slider goes down and presses the block into the desired product.
4. Bus control unit: monitors all production units and their interactions and issues action commands to ensure accurate and safe operation. It consists of three networks: 1. PROFIBUS-DP bus; 2. ETHERNET (industrial Ethernet); SAFETY BUS (Safety Network).

  1. The micro-opening technology of proportional servo is adopted, and the minimum height of stable mold opening can reach 0.1mm.
  2. Adopting the unique fast and slow flexible switching technology, the slider fast and slow conversion realizes the no-flow breakpoint switching, and the safety of the slider operation is greatly improved.
  3. The key parts are sealed by radial sealing, and the oil leakage of the press is effectively controlled.
  4. The thermoplastic composite production line has a complete set of supply capabilities for material processing, molding processes, molds and automated full-line bus control integration.

Thermosetting resins form the matrix and chemical backbone of SMC/BMC, imparting the required blend of properties. Unsaturated polyester (UP) or vinyl ester (VE) are the resins most commonly used, and they undergo a cross-linking reaction when cured under heat and pressure. VE resins are used when there is a high technical requirement, for example where sustained heat and chemical resistance is needed. Good heat resistance is a characteristic of all thermosets and they differ from thermoplastics in that once the compound cures to a rigid solid, it will not soften at elevated temperatures or become brittle at lower temperatures. This means that SMC and BMC parts retain their original properties and dimensional accuracy over a broad range of temperatures.
