Small Size 400*400mm Hot Plate Rubber Vulcanizing Machine For Producing Rubber And Silicone Products

Machine Introduction:

The silicone 500×500 hot plate vulcanizer is a device used for vulcanization and molding of silicone products. Here is some information about it:

1. Working principle:
- The motor drives the oil pump to work, and the oil is transported from the oil tank through the oil filter, oil pump, and control valve to the oil cylinder, driving the plunger to rise and close the hot plate. When the pressure reaches the specified value, if the motor stops running, the one-way valve will automatically close to maintain the pressure in the oil cylinder. The hot plate heats the silicone material, making the rubber material warm and soften, and the internal moisture and volatile substances are vaporized. At the same time, the hydraulic cylinder provides enough pressure to fill the model with rubber, limit the generation of bubbles, and make the product structure dense. During the vulcanization process, the rubber molecules undergo cross-linking reactions, changing from a linear structure to a mesh structure, thereby obtaining a product with certain physical and mechanical properties.
2. Structural features:
- Hot plate: The size is 500×500mm. It is the main working part of the equipment and is used to heat and press the silicone. The material and processing accuracy of the hot plate have an important impact on the quality of the product. Generally, high-quality steel is used and specially treated to ensure uniform heat conduction and precise temperature control.
- Frame: It plays the role of supporting and fixing the hot plate, oil cylinder and other components. The structural design of the frame should have sufficient strength and rigidity to ensure the stability of the equipment during operation.
- Cylinder: It is a component that generates pressure. It pushes the hot plate to close through the movement of the plunger and exerts pressure on the silicone material. The sealing and pressure resistance of the cylinder are directly related to the working efficiency and safety of the equipment.
- Hydraulic system: It includes oil pumps, control valves, oil pipes and other components, which are responsible for providing and controlling the working pressure of the cylinder. The performance of the hydraulic system determines the pressure control accuracy and working reliability of the equipment.
- Heating system: Usually electric heating is used, and tubular resistance heaters are installed in the hot plate to provide heat. This heating method saves electricity, does not form glue, has uniform temperature of the hot plate, and has good insulation performance.
- Control system: PLC programmable controller or other intelligent control methods can be used to accurately control and adjust the temperature, pressure, vulcanization time and other parameters of the equipment. It is easy to operate and has a high degree of automation.
3. Technical parameters:
- Nominal clamping force: Common specifications include 25 tons, 50 tons, 80 tons, etc. The larger the nominal clamping force, the larger the size and thickness of the silicone products that the equipment can press, and the higher the density and strength of the products.
- Plunger stroke: Generally between 200-500mm. The plunger stroke determines the opening and closing distance of the hot plate, affecting the installation of the mold and the removal of the product.
- Motor power: Depending on the size of the equipment and working requirements, the motor power is generally between 2.2-5.2kW.
- Dimensions: Varies depending on the structure and model of the equipment, generally between 1-3 meters in length, width and height.
- Weight: About 1000-2000kg.
4. Application areas: Widely used in the production of silicone products, such as silicone sealing rings, silicone buttons, silicone tubes, silicone plates, etc.
