Take you to understand the role of the cooling system in Plastic Thermoforming Machine
In order to improve production efficiency and ensure product quality, thermoforming products often need to be cooled and shaped before forming, and the cooling efficiency is set according to the product's in-mold temperature. If the cooling is not sufficient, deformation and warping will easily occur; and if the cooling is excessive, the efficiency will be low, especially for punches with small slopes, which may cause difficulty in demolding.
There are two types of cooling: internal cooling and external cooling. Internal cooling is to cool the initial product by cooling the mold. External cooling is to use air cooling (using fans or electric fans) or air, water mist and other methods to cool the products. Separate water spray cooling is rarely used, because it is easy to cause scarring of the product, and it also causes the problem of inconvenient water removal. Ideally, both the inner and outer surfaces of the part in contact with the mold are cooled. Materials such as polyvinyl chloride must be lowered to a relatively low temperature to be demolded after molding, so it is best to use a mold with a built-in cooling coil, and use a cooling system with forced cooling such as air cooling to complete the cooling of the product. Purpose. For products such as polystyrene and ABS, which can be shaped at higher temperatures, the cooling coil may not be installed in the mold, and small products can be cooled naturally.
Most Fully Automatic Thermoforming Machine are suitable for such a cooling system.
