A press mold is a specialized tool used to form various types of products made from a polymer-sand mixture, plastics, rubber, and other raw materials under additional pressure generated by presses of various configurations. Different press molds can significantly expand the range of polymer-sand products that can be manufactured.
A press mold is a cavity that reproduces the contours of the finished product. To produce a finished product, a specified amount of molten polymer-sand mixture is placed in this cavity. The press then applies high pressure to form the finished polymer-sand product.
Depending on the product type and the equipment used, press molds may have different designs, shapes, and configurations. Regardless of the design, every press mold must have a number of essential performance characteristics. These characteristics are especially important because press molds are used directly in the production process. They are exposed to continuous heating and high pressure, so press molds for manufacturing polymer-sand products must offer high strength, wear resistance, corrosion resistance, and chemical resistance.
If press molds are manufactured improperly or from low-quality materials, they will wear quickly. During operation, the mold cavity may also change in size, resulting in low-quality, non-standard products.
Press molds are made from high-quality steel capable of withstanding high loads and designed for long-term operation under demanding conditions.
