Plastics Industry: Temperature Control Units for Injection Molding
Temperature control in injection molding tools is the primary factor influencing unit costs and part quality. ONI combines intelligent temperature control management with efficient cooling/distribution and machine efficiency (EtaControl®) to stabilize process windows and save energy.
- Rhytemper® temperature control management: thermal “fingerprint” per mold circuit, active control of ΔT/flow rate, cycles ~18% shorter on average.
- Efficient temperature control/chilled water technology on the market: e.g., PEM-based temperature control units and R290 chilled water solutions deliver verifiable energy and process benefits.
- Machine optimization (EtaControl®): demand-based oil flow management significantly reduces electricity costs for conventional injection molding machines.
- Higher OEE, less scrap
- Transparent data/visualization: Reliable before/after metrics facilitate approval
- Faster ROI from cycle time, quality, and energy efficiency improvements
- Quality & process stability through intelligent temperature control
- Energy efficiency through integrated PEM/R290 concepts
- Scalability: from single-mold to plant-wide standard
To ensure optimal operation, we at ONI consider the interaction between the mold, the medium, the peripherals, and the process requirements.
- Temperature Control Audit (circuits, ΔT, flow rates, visualization)
- Pilot test on a bottleneck tool, including before/after KPIs
- Refrigeration/Distribution Match (PEM/R290, Water Distribution)
- Rollout & Training (Maintenance/Process)
- Commissioning & Process Stabilization
- Operation, maintenance & transparency
Complexity, Transparency, and Root Cause Analysis
- Complex systems with many loops and different requirements for each zone
- Missing measurement/process data (temperature, flow) → Optimization becomes “trial and error”
- Malfunctions caused by contamination / air / leaks are difficult to detect without monitoring in the temperature control system
