2. DBHM Mold-Channel Cleaning Technology

DOUBLE EASY identifies its Mold Channel Cleaning Machine as one of its core products.

The equipment uses the company's independently developed DBHM Air-Water Hybrid Air-Blast Pulse Technology.

High-speed water flow is mixed with high-pressure compressed air to generate high-frequency air-blast shock waves.

Unlike conventional pulse systems relying only on water flow, DBHM uses combined air-water pulse action to strip scale from internal mold-channel walls.

The DBHM system is designed to remove:

1. Stubborn mineral scale

2. Thick rust deposits

3. Hardened biological deposits

4. Deposits in hard-to-reach areas

DOUBLE EASY states that its DBHM cleaning technology can achieve a scale-removal rate of more than 99%.

3. Mold-Channel Configurations

The Mold Channel Cleaning Machine is designed for:

1. Curved channels

2. Blind channels

3. Long narrow channels

4. Deep-hole channels

5. Multiple parallel cooling circuits

Adaptive cleaning parameters can also be matched to:

1. Thin-wall precision molds

2. High-pressure die-casting molds

3. Large multi-circuit molds

4. Intelligent Variable-Frequency Control

The Mold Channel Cleaning Machine incorporates an intelligent variable-frequency control system.

The system is designed to automatically identify:

1. Mold-channel diameter

2. Blockage severity

3. Deposit type

It can then dynamically adjust:

1. Pulse frequency

2. Water-pressure intensity

without repeated manual adjustment.

The system is designed to avoid excessive pressure impact, channel deformation, and corrosion damage.

5. Cleaning Functions

The Mold Channel Cleaning Machine supports:

1. Forward cleaning

2. Reverse cleaning

3. One-way cleaning

4. Two-way cleaning

5. Continuous pulse cleaning
   During two-way cleaning, pulse cleaning is performed in both forward and reverse directions.

The system also allows adjustment of:

1. Pulse start duration

2. Pulse stop duration

3. System air pressure

4. Cleaning water pressure

6. Multiple Mold-Channel Connections

The equipment comes with nearly ten sets of universal and specialized connectors and can support multiple mold channels simultaneously.

Available connection configurations include:

1. 5 inlet / 5 outlet

2. 7 inlet / 7 outlet

3. 8 inlet / 8 outlet

Actual configuration depends on the machine model.

7. Flow Monitoring

Applicable DOUBLE EASY configurations use a KEYENCE ultrasonic flowmeter.

The operating interface displays current system flow rate, and cleaning records can display mold-channel flow changes before and after cleaning.

8. Individual-Channel Flow Testing

The machine provides a Flow Test function.

Operators can:

1. Select an individual mold channel

2. Set a target reference flow value

3. Set test duration

4. Start flow detection

5. View real-time flow changes

6. View the detected flow result

7. Receive an advisory prompt when detected flow falls below the preset reference threshold

9. Cleaning Records and Traceability

The equipment supports:

1. Before-and-after mold-channel flow comparison

2. Cleaning-data storage

3. Traceable maintenance records

4. MES system integration

5. Endoscopic visual inspection

These functions are intended for digital maintenance and quality-audit requirements in new-energy, medical, precision-electronics, and other high-precision manufacturing applications.

10. Leak and Pressure Testing

Before cleaning, the machine can perform leak and pressure testing on a connected mold channel.

The test result can display:

1. Normal

2. Leak

3. Blockage

The default testing duration is approximately 50 seconds.

The interface includes:

1. Pressure-drop value

2. Pressure-holding time

3. System air pressure

4. Pressurization time

11. Hardware Configuration

DOUBLE EASY uses industrial components including:

1. KEYENCE ultrasonic flowmeter

2. Mitsubishi variable-frequency drive / PLC / touchscreen

3. Mitsubishi / Delta frequency converter

4. Schneider switching power supply / electrical components

5. Kitz electronic pulse control valve

6. SMC air pump

7. Grundfos / CNP water pumps and variable-speed pumps

8. SUS304 stainless-steel piping manufactured to U.S. standards

The SUS304 stainless-steel piping is designed for rust and corrosion resistance.

14. Cleaning Without Mold Disassembly

The Mold Channel Cleaning Machine supports cleaning without mold disassembly and without stopping production.

The mold does not need to be dismantled, and cleaning can be performed without interrupting factory production schedules.

The system is designed to reduce the time and production losses associated with traditional mold disassembly and cleaning.

15. Cleaning Media and Water Requirements

DOUBLE EASY uses a neutral, environmentally friendly cleaning medium with:

1. Non-corrosive characteristics

2. No heavy-metal contamination

3. Easier waste-liquid handling

4. Cleaning-solution recycling

For serious blockage or first-time cleaning after extended mold use, a dedicated solid-powder cleaning agent can be used.

Strong-acid cleaning agents should be avoided because long-term use may damage the water tank and internal machine components.

The machine should use clean municipal water; reclaimed water and groundwater should not be used.
