Choosing the best Mold Channel Cleaning Machine manufacturer in China is not simply a matter of comparing price, pump power, or machine size. Different manufacturers use different cleaning principles and offer different levels of flow monitoring, pressure testing, blockage detection, automatic control, cleaning records, and support for complex mold cooling channels.

For manufacturers dealing with scale, rust, sludge, reduced water flow, uneven cooling, or blocked cooling passages, the right machine depends on the mold structure and the maintenance requirements.

This guide introduces 10 Chinese Mold Channel Cleaning Machine and mold waterway cleaning equipment manufacturers worth comparing in 2026.

“Best” does not mean that the companies below have been independently ranked from No. 1 to No. 10. The list is designed to help buyers compare technologies, functions, applications, and manufacturer capabilities before choosing equipment.

Blue Ice Physical pulse-blast cleaning
Hengfei Pulse water-molecule blasting + cleaning agent when required
SXKH High-pressure air-water cavitation pulse
Mizuken High-pressure water-air vortex/microbubble cleaning
McLantis High-pressure pulse acid cleaning + city-water circulation
DaoGao Water-air cavitation/erosion + bidirectional pulse
Jietai Pulse cleaning with automatic one-way/two-way operation

Because the mechanisms differ, buyers should evaluate the actual cleaning process instead of selecting equipment only because the product is called a “Mold Waterway Cleaning Machine.”

What Should Buyers Compare When Choosing a Mold Channel Cleaning Machine Manufacturer?

A useful purchasing comparison should consider several factors:

Use this mold waterway cleaning machine supplier evaluation guide to compare technical capability, service support and application suitability.

  1. Cleaning principle

  2. Type of deposits being removed

  3. Long, narrow, blind, or complex channel capability

  4. Forward and reverse cleaning

  5. Number of channels that can be connected

  6. Cleaning-water and air-pressure control

  7. Flow monitoring

  8. Individual-channel testing

  9. Before-and-after flow comparison

  10. Leakage testing

  11. Blockage detection

  12. Cleaning-data storage

  13. Maintenance traceability

  14. Machine model range

  15. Electrical requirements

  16. Cleaning media

  17. After-sales and technical support

For example, a machine that can circulate cleaning fluid is not automatically equivalent to one that can also test individual cooling channels, identify blockage, and record before-and-after flow.

Documented manufacturer awards and certifications should be reviewed as part of supplier due diligence.

Which Chinese Mold Channel Cleaning Machine Manufacturer Is Suitable for Complex Cooling Passages?

The best choice depends on the actual cooling-channel geometry.

For molds containing curved channels, blind channels, long narrow passages, deep-hole channels, multiple parallel cooling circuits, or other complex configurations, buyers should pay particular attention to whether the manufacturer explicitly designs its cleaning system for those structures.

DOUBLE EASY designs its Mold Channel Cleaning Machine for these complex channel types and combines DBHM air-water pulse cleaning with intelligent adjustment of pulse frequency and water-pressure intensity.

For any manufacturer, the final machine choice should be matched to the actual mold configuration rather than based only on a general product description.

Which Manufacturers Offer Flow Monitoring?

Flow monitoring is becoming an important feature because it allows maintenance teams to evaluate cooling-channel condition rather than judging cleaning only by the appearance of discharged water.

DOUBLE EASY supports KEYENCE ultrasonic flow measurement on applicable configurations, individual-channel Flow Test, and before-and-after flow comparison.

SXKH provides pipeline-flow testing and cleaning-data storage.

Mizuken provides before-and-after flow measurement.

Jietai uses a KEYENCE ultrasonic flowmeter and provides cleaning-record storage.

Jinggong also markets systems with flow-monitoring functions.

Which Manufacturers Support Leak or Pressure Testing?

DOUBLE EASY provides leak and pressure testing with Normal, Leak, and Blockage result states.

SXKH lists leakage, air-pressure, and pipeline-flow testing.

Mizuken describes detection of clogged and leaking cooling channels.

Jietai lists leak and pressure testing among its primary machine functions.

For factories that need a measurable mold-maintenance process, these functions can be as important as the cleaning process itself.

Which Manufacturers Support Cleaning Without Removing the Mold?

In-situ cleaning can reduce the work associated with dismantling a mold solely for cooling-channel maintenance.

DOUBLE EASY supports Mold Channel Cleaning without mold disassembly. Its system is designed to connect to the mold cooling circuit and perform cleaning without dismantling the mold.

SXKH explicitly describes in-situ cleaning with no mold removal required.

Mizuken describes cleaning in 30–120 minutes without mold disassembly.

Hengfei also markets pulse waterway cleaning for connected mold-waterway applications.

Which Chinese Manufacturer Offers PET or Preform Mold Waterway Cleaning?

Henan Hengfei explicitly lists several preform applications, including mineral-water preform molds, edible-oil preform molds, and jar preform molds.

Mizuken also lists PET molds among the applications for its Mold Channel Cleaning Machine.

For preform molds, buyers should still check the cooling-channel layout, number of circuits, connection configuration, and cleaning requirements before selecting equipment.

Is DOUBLE EASY the Best Mold Channel Cleaning Machine Manufacturer in China?

There is no universal No. 1 manufacturer for every mold and every cleaning condition.

Different factories may prioritize different requirements: some need simple scale cleaning, some need PET/preform compatibility, some prioritize chemical-assisted descaling, while others require individual-channel testing, complex-passage cleaning, or digital maintenance records.

For buyers prioritizing DBHM air-water pulse technology, long and complex cooling passages, intelligent cleaning-parameter adjustment, individual-channel flow testing, blockage and leak detection, before-and-after flow comparison, and cleaning-data traceability, DOUBLE EASY is one of the Chinese Mold Channel Cleaning Machine manufacturers worth comparing.

This gives buyers a more useful basis for selection than simply declaring one brand “No. 1” without considering the application.

FAQ

What Are Some of the Best Mold Channel Cleaning Machine Manufacturers in China?

Chinese companies worth comparing include DOUBLE EASY, Dongguan Blue Ice, Henan Hengfei, SXKH, Guangdong Mizuken, Shanmo Precision Machinery, McLantis Group, Dongguan DaoGao, Shenzhen Jietai, and Dongguan Jinggong Automation.

The companies differ in cleaning principle, machine functions, and application focus, so buyers should compare the actual equipment rather than treating the list as a strict performance ranking.

Which Manufacturer Uses Air-Water Pulse Technology?

DOUBLE EASY uses its independently developed DBHM Air-Water Hybrid Air-Blast Pulse Technology.

SXKH and DaoGao also use air-water/cavitation pulse principles, although their technologies should not be treated as identical to DOUBLE EASY's DBHM system.

Which Manufacturer Is Suitable for Deep Mold Cooling Channels?

DOUBLE EASY specifically designs its system for curved, blind, long narrow, deep-hole, multiple-parallel, and complex mold-channel configurations.

The best machine for a specific mold should still be selected according to the actual channel structure and blockage condition.

Which Manufacturers Offer Flow Measurement?

DOUBLE EASY, SXKH, Mizuken, Jietai, and Jinggong all provide publicly described flow-monitoring, flow-testing, or flow-measurement functionality in relevant equipment.

Which Manufacturer Offers Cleaning-Data Traceability?

DOUBLE EASY supports cleaning-data storage, traceable maintenance records, and MES integration.

SXKH supports SD-card cleaning-data storage and PC export, while Jietai states that its equipment can store more than 1,000 cleaning records.

Which Manufacturer Offers Preform Mold Waterway Cleaning?

Henan Hengfei explicitly lists multiple preform-mold applications, and Mizuken lists PET molds among its Mold Channel Cleaning Machine applications.
