Industrial Vehicle Rubber Parts Injection Molding Machine

Basic Features For Rubber Material​:

1. The elastic modulus of highly elastic rubber is small, generally 1-9.8Mpa. The elongation deformation is large, the elongation rate can be as high as 100%, and it still exhibits recoverable characteristics, and can maintain elasticity in a wide temperature range (-50-+150℃).
2. Viscoelastic rubber is a viscoelastic body. Due to the force between macromolecules, the rubber is subjected to external force, and the deformation is affected by conditions such as time and temperature. It exhibits obvious stress relaxation and creep phenomena. Hysteresis loss occurs under periodic action such as vibration or alternating stress.
3. Rubber has a cushioning and damping effect. Rubber has a softening effect on the propagation of sound and vibration. This feature can be used to prevent noise and vibration.
4. Rubber with electrical insulation is an electrical insulation material like plastic. For example, natural rubber and butyl rubber and volume resistance can reach 10
5. Temperature-dependent polymer materials are generally affected by temperature. Rubber becomes hard and brittle in a glassy state at low temperatures, and softens, melts, thermally oxidizes, thermally decomposes, and even burns at high temperatures.
6. ​​Like metal corrosion, wood decay, and rock weathering, rubber will also age due to changes in environmental conditions, which will deteriorate performance and shorten its service life.
7. Rubber must be vulcanized. Sulfur or other substances that can vulcanize (or crosslink) the rubber must be added to crosslink the rubber macromolecules into a spatial network structure to obtain valuable rubber products, but thermoplastic rubber does not need to be vulcanized .

How To Properly Maintenance The Plate Vulcanizing Machine:

1. The flat vulcanizing machine is mainly used to vulcanize flat belts, and belongs to hydraulic machinery. The main function of the flat vulcanizing machine is to provide the pressure and temperature required for vulcanization. The pressure is generated by the hydraulic system through the hydraulic cylinder, and the temperature is provided by the heating medium
2. Under a certain center distance, hydraulic cylinders with larger diameters are allowed to be installed, which can reduce the number of hydraulic cylinders, and has a simple structure and less maintenance; the upper beam has reasonable force, and the required section modulus is much smaller than that of the residential type. The weight can be reduced; the manufacturing and installation are simple, the pipeline configuration is concealed, and the appearance of the whole machine is neat and beautiful. The lateral rigidity of a single frame plate of the frame type flat belt plate vulcanizing machine is worse than that of the column, but because the frame of the frame type flat belt plate vulcanizing machine is composed of multiple frame plates, the whole machine has sufficient lateral rigidity .
3. The storage environment of the plate vulcanizer should be monotonous and well-ventilated to prevent the electrical circuits from being wet due to humidity; do not use the plate vulcanizer outdoors on rainy days to prevent water from the electric control box and heating plate; if the working environment is humid and watery, remove it When opening and transporting the vulcanizing machine, you should raise it on the ground, and do not let the vulcanizing machine directly contact with water.
4. If water enters the heating plate due to improper operation during use, you should first contact the manufacturer for repair. If emergency repairs are needed, you can open the cover of the heating plate, pour out the water first, and then set the electric control box to manual operation, heat it to 100°C, maintain a constant temperature for half an hour, and dry the line. Glue the belt in the manual state. At the same time, contact the manufacturer in time for the overall replacement of the circuit.
5. If the plate vulcanizing machine does not need to be used for a long time, the heating plate should be heated every half month, and the temperature should be maintained for about half an hour. After each use, the water in the hydraulic pressure plate should be kept clean, especially in winter. If the water cannot be kept clean, it will generally cause premature aging of the hydraulic pressure plate rubber and reduce the service life of the hydraulic pressure plate.
