WHY YOUR COMPANY NEEDS THIS MACHINE - PROBLEMS WITH MOLD PIPELINES
Internal Deposits and Contamination Reduce Cooling Efficiency and Production Stability
During production, mold pipelines circulate cooling media such as water or processing fluids to control mold temperature. Over time, repeated heating and cooling cycles cause mineral scale buildup, corrosion deposits, rust formation, and biological contamination including bacteria and algae growth inside cooling channels.
These contaminants restrict internal pipeline diameter and reduce heat exchange efficiency. As cooling performance declines, manufacturers may experience unstable mold temperatures, increased defect rates, longer cycle times, and higher overall production costs.
Industry research indicates that even small levels of scale buildup inside cooling pipelines can significantly reduce heat exchange performance. Maintaining clean cooling channels is essential to preserving mold efficiency, maintaining product quality, and minimizing production downtime.
WHAT IS THE IMPACT OF CLOGGED WATER CHANNELS ON PRODUCTION & EFFICIENCY?
Cooling Channel Contamination Reduces Product Quality, Slows Cycle Times, and Increases Manufacturing Costs
Defective Products:
The surface temperature of the mold cavity is not uniform, resulting
in large shrinkage and warping deformation of the product.
Lower Efficiency:
Reduced heat exchange efficiency increases cooling cycle duration and slows overall production throughput, reducing manufacturing efficiency.
Higher Costs:
Increased costs and longer production cycle times lead to higher
overall production costs for the enterprise.
Industry research indicates that even small levels of scale buildup inside cooling pipelines can significantly reduce heat exchange performance. Maintaining clean cooling channels is essential to preserving mold efficiency, maintaining product quality, and minimizing production downtime.
HOW TO RESTORE COOLING FLOW AND IMPROVE PRODUCTION EFFICIENCY IN MACHINERY?
Increase Heat Exchange Performance and Reduce Cycle Times
Scale buildup, rust, and biological contamination inside mold cooling channels restrict coolant flow and reduce heat exchange efficiency. Even minor buildup inside cooling pipelines can significantly increase mold surface temperatures, resulting in longer cooling times, unstable product quality, and higher defect rates.
The MDM Series restores internal channel diameter and cooling flow by removing contamination from mold cooling circuits. Improved coolant circulation stabilizes mold temperature and enhances heat transfer efficiency, allowing manufacturers to shorten cooling cycles and improve overall production throughput. In documented customer cases, improved flow performance has resulted in measurable cycle time reductions and increased hourly production output.
By restoring cooling performance, the MDM Series helps manufacturers maintain consistent part quality while maximizing production efficiency and reducing energy consumption.
CAN THIS MACHINE CLEAN MORE THAN JUST MOLDS?
Yes. this Machine is Both Versatile and Multi Functional
The MDM Series is engineered to do far more than standard mold and die cooling channel cleaning. Designed for maximum versatility and performance, this advanced cleaning system features two independent port sizes to handle a wide range of industrial applications.
The smaller ports are optimized specifically for precision cleaning of mold and die cooling circuits, restoring proper flow, improving heat transfer efficiency, and reducing cycle times. The larger ports expand the machine’s capability beyond tooling, allowing operators to effectively clean heat exchangers, temperature control units (TCUs), water chillers, dehumidifiers, dryers, and other process equipment with internal cooling lines.
Over time, scale, rust, algae, and mineral buildup restrict flow and reduce system efficiency. The MDM Series helps eliminate these blockages, extending equipment life, stabilizing production quality, and lowering energy costs.
With its dual-port flexibility and heavy-duty industrial design, the MDM Series is a complete solution for maintaining optimal cooling performance across your entire facility.
HOW DOES CAVITATION PULSE TECHNOLOGY WORK TO CLEAN WATER CHANNELS?
Simple Yet Powerful Bi-Directional Flushing for Complete Channel Cleaning Coverage
The MetalPress MDM Series uses advanced cavitation pulse cleaning technology to remove scale, rust, carbon buildup, biological contamination, and debris from internal mold cooling channels. The system combines high-pressure air and high-pressure water and releases the mixture in controlled pulses that generate microscopic cavitation bubbles inside the pipeline.
As these bubbles rapidly compress and collapse, they create powerful micro-shockwaves that break apart scale and contamination attached to internal channel walls. The pulsed cleaning flow operates in both forward and reverse directions, ensuring complete removal of buildup throughout complex mold cooling passages. This physical cleaning method restores cooling flow performance while eliminating the need for aggressive chemical treatments or manual cleaning.
CAN YOU CLEAN MOLD CHANNELS WITHOUT REMOVING THE MOLD?
Reduce labor and Maintenance Downtime by Leaving the Mold in The Molding Machine
Yes! The MDM Series is designed to clean mold cooling channels while the mold remains installed on the injection molding or die casting machine. Traditional maintenance methods often require mold removal, disassembly, and manual cleaning, which can take hours or even days and increases the risk of mold damage or alignment issues.
By allowing in-place cleaning, the MDM Series significantly reduces maintenance downtime and labor requirements while maintaining mold accuracy and surface integrity. The system circulates pulsed cleaning media directly through the cooling circuits, flushing out contamination and restoring cooling efficiency without interrupting overall production workflows for extended periods.
This streamlined maintenance approach helps manufacturers maintain consistent mold performance while minimizing production disruptions and costly machine downtime.
DOES THIS MACHINE HAVE MULTIPLE CHANNELS TO SPEED UP CLEANING?
Clean More Channels and Molds in Less Time.
Our MDM Series features multiple independent cleaning channels designed to dramatically increase throughput and reduce downtime. Instead of cleaning one mold at a time, or parts of a bigger mold, operators can connect multiple channels to molds or dies to maximizing productivity with every cycle.
Each channel operates with controlled cavitation pulse technology to ensure consistent cleaning performance across all connected circuits. This multi-line capability is ideal for high-volume injection molding and die casting facilities where time is critical and mold availability directly impacts production output.
By reducing waiting time between cleanings and allowing parallel processing, the MDM Series helps improve maintenance efficiency, extend mold life, and keep your operation running at peak performance.
Our MDM mold channel cleaning machines offer more channels per unit size and capacity then any other machine on the market.
DOES THIS MACHINE HAVE LEAKAGE AND PRESSURE DETECTION?
Built-In Monitoring for Safe and Reliable Cleaning Performance
The MDM Series can also check mold or system pressure and system leakage, saving a tremendous amount of time in troubleshooting. These integrated detection systems help identify cooling channel restrictions, seal failures, or abnormal pressure changes before they become costly mold or equipment issues. Real-time monitoring improves cleaning safety while providing operators with greater confidence during maintenance operations.
CAN THIS MACHINE ALSO AUTOMATICLY BLOW DRY THE WATER CHANNELS AFTER CLEANING?
Remove Residual Moisture to Prevent Corrosion and Contamination
The MDM Series includes an automatic blow drying function that removes residual water from mold cooling channels after the cleaning cycle is completed. By eliminating trapped moisture, the system helps prevent internal corrosion, bacterial growth, and contamination buildup between production runs. This feature prepares molds for immediate return to service while helping maintain long-term cooling channel integrity.
DOES THIS MACHINE HAVE A FULLY AUTOMATED CLEANING AND MONITORING SYSTEM?
Consistent, Repeatable Maintenance With Minimal Operator Input
The MDM Series is designed for fully automated mold channel cleaning using integrated PLC controls and touchscreen operation. With one-touch start functionality, operators can initiate complete cleaning cycles while the system automatically regulates air pressure, water pressure, pulse frequency, and cleaning duration based on mold channel conditions.
Built-in monitoring and detection systems continuously track pressure, flow rate, and leakage conditions throughout the cleaning process. The system records cleaning data and maintenance logs, allowing operators to download and store service records for quality control and preventive maintenance scheduling.
