What is a mould temperature controller？

Injection molding is one of the most widespread manufacturing technologies today, and it is used to produce a wide variety of plastic products, ranging from small household products to large home appliances. When the injection molding process officially starts, the plastic temperature needs to be controlled, and the mould temperature controller can control the temperature well during the entire process. This temperature-controlled process begins with the melting of the plastic. Manufacturing takes place after the molten plastic cools. This guide will introduce you to the impact of mould temperature controllers on injection molding.

Effect of temperature on product quality

One factor that affects product quality during the entire injection molding process is mold temperature. As the surface temperature of the mold increases, the appearance quality of the product will also change. Generally speaking, improving the quality of injection-molded products requires increasing the mold temperature during the injection process to reduce the output thickness and insertion pressure. It’s essential to control the temperature effectively during the injection moulding process.

Temperature control via mould temperature controller

Mould temperature controllers work by circulating water through channels in or around the mold. Heating or cooling water to a specific temperature ensures consistent heating conditions during the molding process. At the same time, they can precisely control mold temperature and can quickly switch between heating and cooling, making them suitable for molds that require different temperature stages within a single cycle. Modern mould temperature controllers also function as automatic cooling during idle periods.

Why is a mould temperature controller necessary?

Precise mold temperature management can affect the quality and appearance of the final product, where the temperature of the mold can directly affect the viscosity of the plastic melt. A properly heated mould ensures that the plastic flows evenly and completely fills the mould cavity. If the mould is too cold, the material may solidify prematurely, resulting in short shots. Conversely, an overheated mold may result in excessive packing pressure or extended cooling times.

Uniform mold temperature is essential for reducing internal stress within molded parts. Differences in cooling can cause tension and compression within the plastic, leading to warping, shrinkage, or structural failure. They can also lead to other related problems, such as surface quality defects and short mold life.

Why use a Topstar mould temperature controller?

To meet the needs of industry customers for intelligent and digital upgrades, solve temperature control problems in injection moulding production, and improve product yield, Topstar launched the fourth-generation mould temperature controller. The new generation of mould temperature controllers uses a stainless steel frame structure to upgrade the copper heater because impurities in the water have a lower tendency to adhere to the copper surface and are not easy to scale. At the same time, copper’s ductility and thermal conductivity are superior. It increases the service life by 40% and the efficiency by 10%, and operators can use it effectively even with poor water quality.

In the 120℃ standard water-type mould temperature controller, we have a standard pressure detector with a detection accuracy of 1%. The upper limit of the use temperature can be adjusted according to different water inlet pressures to ensure the mould temperature controller’s regular use when the water inlet pressure is low. This solves the problems of unstable inlet pressure and low water inlet pressure affecting the yield rate.

In addition, the fourth-generation mould temperature controller also has forced cooling and timed appointment power on and off functions. Continuously opening the cooling solenoid valve reduces the mould temperature by about 10 minutes, increasing work efficiency by 10% and dramatically shortening the time required for a mould change. To better ensure that the mould has precise temperature control accuracy, Topstar uses the latest PID temperature control algorithm to improve the temperature control efficiency by 10% and ensure temperature uniformity. At the same time, the hardware part uses solid-state relays for temperature control, with a response time of 0.1s, to ensure that the temperature fluctuates within ±0.1℃ and ensures product yield.

Applications of Mould temperature controller

Mold temperature controllers are crucial in many manufacturing processes. They play a key role in plastic injection moulding, rubber moulding, composite moulding, die casting, and blow moulding.
For die-casting processes, Topstar’s 320° oil-type mould temperature controller has the characteristics of precise temperature control, rapid heating and cooling, and easy maintenance and operation. At the same time, the design separates the electric box to protect electrical components more effectively and ensure safe use. In addition, the magnetic drive pump used solves the problem of natural wear and leakage of the shaft seal, and an over-temperature protection switch is also standard in the motor coil to prevent the motor from overheating and burning, reduce the failure rate, and reduce the risk of accidental touch by personnel.

Faced with the 120℃ large-flow water mould temperature machine featuring high flow and head in the automotive industry, operators select a cooling solenoid valve with a diameter of 20mm.
