Precise temperature control – efficient drive technology for modern temperature control units
How HB-Therm uses Lenze's i510 cabinet to operate speed-controlled pumps precisely, efficiently, and sustainably
Temperature control units are a key component of modern injection molding machines. They regulate the temperature of the mold using a medium such as water, thereby significantly influencing the quality, process stability, properties of the plastic part.
HB-Therm, based in St. Gallen, has been recognized since 1967 as a pioneer in the manufacture of temperature control units for the plastics processing industry. With Thermo-6, the company focuses on precise, reliable, and sustainable temperature control—supported by variable-speed pumps, intelligent control systems, and the i510 cabinet VFD from Lenze.
In plastics processing, temperature control units must:
- Maintain precise and stable temperatures
- Respond flexibly to changing process requirements
- Operate energy-efficiently during continuous operation
- Enable easy integration into the equipment control system
- Precise and responsive control of pump speed
- Stable temperature control for reproducible process results
- Energy-efficient operation through demand-based pump output
- Compact integration into the device
- Direct communication via preconfigured Modbus RTU parameters
- Reduced commissioning effort thanks to coordinated system integration
Benefits for efficient and sustainable temperature control processes
- Energy efficient operation
Variable-speed pumps precisely adjust output to actual demand, reducing energy consumption. - Precise temperature control
The stable and responsive control of the pump speed ensures reliable temperature control throughout the process. - Greater sustainability in operation
Lower energy consumption and reduced wear support more sustainable operation. - Easy Integration
The i510 cabinet can be compactly integrated into the device's electronics; preconfigured communication parameters simplify the integration process. - Quick payback
For users, the combination of efficiency, flexibility, and reduced stress on components means cost-effective operation with a return on investment within just a few years.
Precise temperature control is a critical factor for quality and process stability in plastics processing. With speed-controlled pumps, intelligent control systems, and compact VFD technology, temperature control units can be operated more efficiently—without compromising accuracy or reliability.
