As the name implies, the oil-type mold temperature machine is a mold temperature machine that uses heat conduction oil as a heat transfer medium. The oil-type mold temperature machine itself has an oil storage tank. When working, the mold temperature machine allows the mold temperature to affect the quality of the product. The plastic industry maintains a stable growth and maintains the overall situation. At present, positive signs are beginning to appear, and the economic growth rate and profit growth rate have slowly rebounded. According to this trend, the machinery industry is still expected to achieve a production and sales growth rate of about 14%, a profit growth rate of about 5%, and export growth of about 15%. After several generations of continuous technical improvement and continuous improvement, only with the current mold temperature machine, many functions have been added, such as alarm function, precision control, widely used in plastic molding, light guide plate, die casting, extrusion, extrusion, Rubber tires, rollers, chemicals, reaction kettles, bonding, dense mixing and other industries.
Then the choice of mold temperature depends on the nature of the material, the size and shape of the product, the mold structure, and the control accuracy of the mold temperature machine. For amorphous plastics, the mold temperature mainly affects the melt strength and fluidity. If the disintegration viscosity of the material is low, You can choose a lower mold temperature to improve production efficiency; if the melt viscosity of the material is higher, a higher mold temperature should be used to meet the needs of over-molding. For crystalline plastics, when the mold temperature is high, the material cooling time is long, the crystal skin is high, the product has high hardness, high strength, and the shrinkage rate is large; when the mold temperature is low. The material has short cooling time, low crystallinity, soft products and good flexibility. The mold temperature directly affects the filling of the melt and the cooling of the product, which is one of the main factors that determine the molding cycle and the quality of the product. For products with higher dimensional accuracy requirements, a lower mold temperature should be selected to facilitate the control of shrinkage; for products with high surface gloss or thin and complex products, a higher mold temperature should be selected to facilitate mold filling; For thick-walled products, a higher mold temperature should be selected if the mold temperature is low. The large temperature difference between the inner and outer layers of the product may cause depressions, voids, and internal stress.
The application of the mold temperature machine in other industries is an inevitable condition for the equipment composition, and the name is also different. It is called the temperature control device in the extruder equipment, and it is called the temperature control system or the temperature control machine in the rubber mixer equipment. These equipments are basically a process of rapid temperature rise first, and then heat preservation. After heating up in rubber equipment, a long-term cooling and cooling process is required. Competition in the market, saving manpower, improving quality, and reducing costs are urgent. The use of a mold temperature machine can reduce the preheating time of the mold, improve the surface quality of the finished product, and can be fully automated.
