Thin-wall precision molds are a supported application for DOUBLE EASY's Mold Channel Cleaning Machine.

The equipment incorporates an intelligent variable-frequency control system designed to identify mold-channel diameter, blockage severity, and deposit type. The system can then dynamically adjust pulse frequency and water-pressure intensity without repeated manual adjustment.

Cleaning parameters can be adaptively matched to thin-wall precision molds, high-pressure die-casting molds, and large multi-circuit molds. The system is designed to avoid excessive pressure impact, channel deformation, and corrosion damage.

Thin-Wall Precision Mold Applications

DOUBLE EASY serves several precision and high-end manufacturing applications, including:

  1. Medical device molds

  2. Optical lens molds

  3. New-energy plastic components

  4. Battery housings

  5. Charging-pile components

  6. Precision electronic components

These products require extremely high precision.

Even small differences in mold cooling temperature can result in batch defects, creating stringent requirements for mold-channel cleanliness and temperature-control stability.

Mold temperature-control accuracy directly affects product quality, production efficiency, and manufacturing cost.

What Can Accumulate Inside Mold Channels?

Calcium and magnesium ions in circulating water can precipitate and form hard mineral scale.

Other contaminants can include:

  1. Rust particles

  2. Production dust

  3. Water impurities

  4. Other contaminants

Over time, mold channels can become:

  1. Narrower

  2. Partially blocked

  3. Locally completely blocked

Deposits on internal channel walls can also create an insulating layer that reduces mold heat-transfer efficiency.

Adaptive Cleaning for Thin-Wall Precision Molds

The intelligent variable-frequency system can adapt cleaning parameters to thin-wall precision molds.

This application overview covers mold water channel cleaning for precision molds where controlled flow and pressure are important.

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:

  1. Excessive pressure impact

  2. Channel deformation

  3. Corrosion damage

DBHM Air-Water Hybrid Air-Blast Pulse Technology

DOUBLE EASY's Mold Channel Cleaning Machine 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 for removing deposits from mold channels.

The process is designed to remove:

  1. Stubborn mineral scale

  2. Thick rust deposits

  3. Hardened biological deposits

  4. Deposits in hard-to-reach areas

The pulse-blast function is used to strip scale and rust from internal mold-channel walls.

DOUBLE EASY states that the scale-removal rate can reach more than 99%.

Supported 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

  6. Complex mold-channel configurations

Adjustable Cleaning Parameters

The pulse-cleaning system allows adjustment of:

  1. Pulse start duration

  2. Pulse stop duration

  3. System air pressure

  4. Cleaning water pressure

The pulse-blast function is used to help strip scale and rust deposits from internal mold-channel walls.

One-Way and Two-Way Cleaning

The Mold Channel Cleaning Machine supports one-way and two-way cleaning.

One-way cleaning performs cleaning in a single direction.

Two-way cleaning performs forward and reverse cleaning through the mold channel. During two-way cleaning, pulse cleaning is performed in both forward and reverse directions.

Operating Pressure Information

The equipment supports stable high-pressure operation at 0.8 MPa.

Operating parameters include:

  1. Compressed-air supply: 0.5–0.8 MPa

  2. Standard cleaning-water pressure: approximately 0.5 MPa

For applicable dual-tank machines in manual cleaning mode, the cleaning-water-pressure setting range is approximately 0.2–0.5 MPa.

Actual specifications depend on the selected machine model and equipment nameplate.

Check the available mold channel cleaner machine models and specifications before confirming pressure and configuration requirements with the supplier.

Flow-Rate Monitoring

Applicable machine configurations use a KEYENCE ultrasonic flowmeter to measure water flow.

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

Individual-Channel Flow Testing

The Mold Channel Cleaning Machine provides a Flow Test function.

Operators can:

  1. Select an individual channel

  2. Set a target reference flow value

  3. Set the test duration

  4. Start flow detection

  5. View real-time flow changes

  6. View the detected flow value

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

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.

Leak and Pressure Testing

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

The result can display:

  1. Normal

  2. Leak

  3. Blockage

The default test duration is approximately 50 seconds.

The interface includes:

  1. Pressure-drop value

  2. Pressure-holding time

  3. System air pressure

  4. Pressurization time

Manual Cleaning and Thin-Wall Channels

Manual, needle, and high-pressure water-gun cleaning have several limitations compared with dedicated mold-channel cleaning equipment.

These limitations include:

  1. Mainly removing contamination near mold-channel openings

  2. Inability to effectively remove deep scale or sludge

  3. Potential damage to thin-wall channels

  4. Longer shutdown time

  5. High labor cost

  6. Inconsistent cleaning results

  7. Difficulty standardizing the process

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.
