Why does Injection Moulding use a Chiller?

Few people know the impact of cooling rate on the physical strength and internal stress of the final product. The same injection moulding machine, raw materials, and injection volume are set every time.

When the product’s design requirements are different, the requirements for mould temperature control are also different. Different mould parts require different temperature curves, so they require multiple temperature control devices, and the chiller is one of them.

The special products of the chiller have high requirements for internal stress and physical strength, which can meet the cooling needs of the injection moulding process.

The high-temperature injection moulding machine melts the plastic material in the injection moulding process. Then, it injects it into the mould, forming the plastic product we are familiar with.

The plastic material will generate a lot of heat during this process. If the heat is not dissipated in time, it will cause the plastic material to overheat and affect the quality of the product.

Generally, if a cooling water tower is directly used to cool the mould, the temperature control accuracy is not high, and the fluctuation is large. However, the cooling speed and temperature control accuracy are fast if a chiller is used for cooling.

Chiller equipment such as high-precision laser chillers, micro laser chillers, ultraviolet, ultra-fast laser chillers, etc., have temperature control accuracy of up to ±0.1°C and fast cooling speeds. Injection moulding produced with the assistance of chillers The parts will reach the best state in terms of physical strength and internal stress, and the surface finish of the injection moulded products produced will be relatively high.

The chiller’s refrigeration, cooling, and constant temperature functions can ensure that the injection moulding machine works within a suitable temperature range, maintains stable operation, and reduces the machine failure rate; precise temperature control can achieve the best production status and ensure product quality.
