Topstar copper heater Copper Heater

In terms of structural materials, the newly upgraded copper heater makes the impurities in the water less likely to adhere to the copper surface and not easy to scale. Copper has excellent ductility and thermal conductivity, with a lifespan of 40% and an efficiency of 10%.

Topstar filtration Filtration

The mold temperature controller can be used normally even when the water quality is poor. At the same time, it is equipped with a 50-mesh high-precision filter and an optional precision filter with a 30μm filtration grade. The filter aperture is about 0.03mm, which can effectively filter impurities and prevent mold clogging.

Topstar liquid-level detection Ultrasonic Media Inspection

Detection is achieved by monitoring changes in the intensity of sound waves as they propagate through the medium. The system remains unaffected by the presence of minor oil traces or impurities, as well as by high-temperature and high-pressure conditions; it is entirely immune to issues such as impurity adhesion, mechanical jamming, or damage leading to water ingress, ensuring stable, long-term operation.

Heat Medium Recovery and Pure Water Circulation

Heat Medium Recovery

In the fourth-generation mold temperature controller, the heat medium recovery technology is used to completely replace the residual medium in the mold with high-pressure gas, thereby preventing the mold from being damaged and improving the product yield.

Pure Water Circulation

The pure water series mold temperature controller has its water tank, uses pure water as the circulating medium, and a closed circulation system to prevent metal ions from corroding the mold and scale from clogging the mold. Reduce the requirements for water quality to avoid mold rust.

SELECTION GUIDE

What Should You Confirm Before Selecting a Mold Temperature Controller?

A suitable mould temperature controller must match the mold’s temperature window, heating requirement, circulation demand, and number of independently controlled zones. Confirm these conditions before choosing a model.

Water or oil? Match the operating temperature and cooling-water conditions.

Operating Temperature and Cooling-Water Conditions

Specify both the highest and lowest temperatures required during production. A model’s maximum temperature rating alone does not establish whether it can maintain the required conditions under load.

Also confirm the available cooling-water temperature, pressure, and supply capacity. A mould temperature controller transfers heat to the cooling-water supply; it does not generate refrigeration. Low-temperature requirements may therefore need a suitable chilled-water source.

How much heating power? Size the heater for mold weight and the required preheating time.

Mold Weight and Required Preheating Time

Heating power should be assessed using mold mass, starting temperature, target temperature, and the time available for preheating.

For example, heating an 800 kg mold from 30°C to 110°C within one hour gives an estimated heater requirement of approximately 10.64 kW using the material assumptions and allowance in Topstar’s selection example. A 12 kW configuration can then be considered for further assessment.

This is a preliminary preheating estimate. Continuous-production heat load, heat losses, and cooling requirements must be evaluated separately.

Which pump configuration? Match the target flow to the resistance of the mold circuits.

Required Flow and Mold-Circuit Resistance

Provide the required circulation flow and pressure-loss information where available. Circuit length, channel diameter, parallel branches, and restrictions affect the pump’s actual operating point.

A high-flow configuration may suit molds requiring greater total circulation, while more restrictive circuits require sufficient pump head at the target flow. Injection molding machine tonnage can provide initial context, but should not replace a mold-circuit assessment.

One temperature zone or two? Use independent zones when mold halves need different temperatures.

Independent Temperature Zones and Installation Requirements

If the fixed and moving mold halves require different temperatures, consider a dual-zone configuration or separate units. Size the heater and pump for each controlled circuit.

Before ordering, confirm supply voltage and frequency, connection sizes, cooling-water conditions, and any communication requirements.

For a model recommendation, send Topstar your target temperature range, mold weight, preheating time, circuit requirements, cooling-water conditions, and electrical supply.
