Application of mold temperature machine in plastic industry (what are the advantages of using mold temperature machine);
1. Improve the molding efficiency of products.
2. Reduce the generation of defective products
3. Improve the product appearance and suppress product defects.
4. Accelerate production progress, reduce energy consumption and save energy.
Application of mold temperature machine in die casting industry;
Especially in the manufacture of magnesium alloy and aluminum alloy, uneven or improper mold temperature will lead to unstable casting size, deformation and ejection of castings in the production process, and defects such as hot pressing, mucous membrane, surface depression, internal shrinkage cavity and hot bubbles appear. It will also have an impact on the production and filling time. Widely used in plastic molding, light guide plate die casting, extrusion, rubber tire roller chemical reaction kettle bonding and internal mixer and other industries.
The function of mold temperature machine is to control the temperature during injection molding, heat or cool the mold and keep its working temperature, ensure the quality stability of injection molded parts and optimize the processing time. There are two kinds of mold temperature machines: water temperature machine and oil temperature machine. In the injection molding industry, mold temperature plays a decisive role in the quality of injection parts and injection time.
The working principle of mold temperature machine is to control the temperature of oil or water when it flows through the mold to achieve the best molding effect.
Using water level heat transfer medium, the highest temperature can reach 160 degrees, and the standard is 95 degrees.
Using oil as heat transfer medium, the maximum temperature can reach 200 degrees, and the standard type is 140 degrees.
The mold temperature machine adopts the indirect cooling method of cooler, then vacuumizes and pressurizes, heats with electric heating tube at high temperature, and then sends it into the mold to meet the requirement of heating at constant temperature. Accurate temperature control instrument can ensure stable temperature control, and it is an essential mechanical equipment for plastic mold forming.
