The main role of gas mold temperature machine
announcer:
Mold temperature machine is more commonly used in the plastics industry, the main functions are: 1. Improve the molding efficiency of the product; 2. Reduce the generation of defective products; 3. Improve the appearance of the product and suppress the defects of the product; 4. Speed up the production schedule and reduce the Energy consumption and energy saving. There is also a lot of room for the use of mold temperature machines in the die-casting industry. Especially in the manufacture of magnesium alloys and aluminum alloys, uneven or inappropriate mold temperatures can cause unstable casting dimensions and eject the casting deformation during the production process. Defects such as thermal pressure, sticky mold, surface depression, internal shrinkage holes and thermal bubbles are generated. It also has an impact on the production cycle, such as filling time, cooling time and spraying time all produce unstable variables. The life of the mold will also be affected by excessive cooling and overheating, resulting in thermal cracking of the expensive steel and accelerating its aging. In a modern factory, in response to market competition, the business strategy of saving manpower, improving quality, and reducing costs is 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. Increasing mold life is a necessary means to increase productivity. The use of temperature controllers in other industries is an inevitable condition for equipment composition, and the terms are also different. It is called oil heater in the temperature control of PVC sheet rollers, temperature control device in extruder equipment, and temperature control system or temperature control machine in rubber mixer equipment. These equipment are basically a first Rapid heating, then the process of heat preservation. After heating up in rubber equipment, a long-term cooling and cooling process is required.
