For plastics, the main purposes are as follows:

Maintain the mold temperature at a constant working temperature.

2. For thermoplastic materials, a higher mold temperature generally improves surface quality and flowability, but it extends the cooling time and injection cycle. A lower mold temperature reduces shrinkage within the mold, but increases the shrinkage rate of the molded part after demolding.

3. For thermosetting plastics, a slightly higher mold temperature typically reduces cycle time, with the duration determined by the cooling time required for the parts.

The mold temperature control machines offered by our company are available in two types of heating or cooling methods: oil separation and water circulation. They are used in rubber and plastic equipment for extrusion and injection molding processes. Our mold temperature control machines are suitable for applications in PC, PP, lens injection molding, carbon fiber hot pressing molds, PVC extrusion dies, and artificial board hydraulic presses.

The mold temperature controller utilizes the most precise components in the industry, complemented by the persistent pursuit of excellence by the team at Jiu Yang, thereby achieving the safety, energy efficiency, and environmental protection goals that manufacturers aim for in their production equipment.

Our country's research on mold temperature control machines started late, only beginning in the late 1970s, but progress has been rapid. Some products have caught up with international counterparts. The production materials can be divided into two main categories: one is made from petroleum products, known as heat transfer oil. Due to the high specific heat capacity of oil and the ability to select appropriate fractions, resources are also abundant. Generally, naphthenic or aromatic mixed-base raw materials are used, along with antioxidant and heat-resistant additives to produce it. The other category is produced from organic substances.
