In order to obtain high-quality products, in addition to applying conformal media channels, the key is to increase the surface temperature of the mold cavity. Although the use of ordinary mold temperature machines can obtain high-quality products, due to the high mold temperature, the product cooling time Larger, especially for larger products, resulting in lower injection production efficiency. In recent years, the rapid hot and cold injection mold temperature control machine gradually applied in the mold manufacturing industry can effectively solve this problem.
Rapid hot-cold injection mold temperature controller can quickly raise the surface temperature of the cavity above the thermoforming temperature of the resin through high-temperature medium (such as steam, water or thermal oil), so as to achieve rapid injection and filling, achieve cooling-free forming and obtain high Plastic parts with very bright appearance, toughness and strength, to overcome the undesired phenomena such as distortion, surface depression, welding marks, ripples, etc .; After the molding is completed, by switching the valve and introducing the cooling medium, the temperature of the mold can be rapidly reduced and greatly reduced Injection cycle.
