Stabilise Your Moulding Process with the Right Temperature Controller
Injection moulding and die casting depend on consistent mould temperatures. Without precise control, you face warpage, shrinkage, longer cycle times, and higher scrap rates. A mould temperature controller (also called a temperature control unit, TCU) circulates heated or cooled fluid through the mould channels to maintain a set temperature. Brands like ABB, Siemens, and Honeywell offer reliable controllers for the Indonesian plastics, rubber, and metalworking industries. At 3G Electric, we have over 35 years of experience delivering process control solutions across Indonesia — including mould temperature controllers matched to your exact process needs.
How a Mould Temperature Controller Works
The MTC consists of a heating element, a cooling valve (or direct cooling circuit), a circulation pump, and a PID controller. Temperature sensors (thermocouples or RTDs) feed back the actual mould temperature; the controller adjusts heating or cooling to maintain the setpoint. Water-based units are common for moderate temperatures (up to 90 °C or 180 °C with pressurisation), while oil-based units handle higher temperatures (up to 350 °C).
Key Specifications
When comparing models, pay attention to these parameters.
| Specification | Typical Range |
|---|---|
| Temperature range (water) | 20 °C – 90 °C (atmospheric) / 20 °C – 180 °C (pressurised) |
| Temperature range (oil) | 50 °C – 350 °C |
| Temperature stability | ±1 °C (standard) / ±0.5 °C (precision) |
| Cooling capacity | 12 kW – 120 kW (water) / 6 kW – 60 kW (oil) |
| Pump flow rate | 20 L/min – 200 L/min |
| Pump pressure | 3 bar – 10 bar |
| Heating capacity | 9 kW – 48 kW |
| Connection size | G½″ – G1½″ |
| Control type | On/Off, PID, or self-adaptive |
Types and Applications in Indonesia
Two main types dominate the local moulding industry:
- Water-based MTCs: Ideal for injection moulding of thermoplastics (PP, ABS, PS) in Jakarta's automotive and consumer goods sectors. Also used in extrusion lines and low-temperature die casting.
- Oil-based MTCs: Suited for high-temperature processes such as rubber curing (e.g., vulcanisation) and high-performance engineering plastics (e.g., PEEK, PSU). Common in tyre manufacturing plants in West Java and Batam.
Selection Criteria – How to Choose the Right MTC
- Identify your process temperature: Determine the required mould temperature range. Water-based units cover up to 180 °C; above that, switch to oil.
- Estimate cooling load: Calculate the heat to be removed (kW) based on part weight, material specific heat, and cycle time. Select a controller with cooling capacity exceeding your peak demand by 20 %.
- Check pump performance: Ensure pump flow and pressure match the mould channel geometry. Higher restriction moulds need more pressure; higher flow reduces ΔT.
- Verify temperature accuracy: For tight-tolerance parts (e.g., medical devices), choose a unit with ±0.5 °C stability and self-tuning PID.
- Consider fluid compatibility: Water must be treated (e.g., deionised or with corrosion inhibitor); oil must have the right viscosity for the pump.
- Evaluate control features: Look for digital interfaces, remote monitoring (Modbus, Profibus), and alarm outputs for over-temperature or low flow.
- Assess local support: Choose a supplier with on-ground support in Indonesia — spare parts availability and technical service are critical to minimise downtime.
According to ABB Mould Temperature Controller Installation Manual, 2021: "For water-based units operating above 90 °C, a closed-loop pressurised system is mandatory to prevent flashing. Always install a pressure relief valve set at 6 bar for pressurised water circuits."
