GOOGIO Dispensing Machine Cleaning Guide: Procedure & Tips

The enduring accuracy and reliability of precision equipment hinge not only on superior engineering but also on disciplined, regular maintenance. For GOOGIO dual-component dispensing machines, a thorough cleaning cycle is fundamental to ensuring long-term stability, preserving metering accuracy, and preventing cross-contamination between materials. This guide outlines a clear and safe standardized operating framework for effective machine cleaning.

I. Core Principles: Safety, Compatibility, Thoroughness

Before commencing any cleaning operation, always adhere to these three principles:

1. Safety First: Operators must wear appropriate PPE (safety glasses, chemical-resistant gloves) and work in a well-ventilated area.

2. Material Compatibility: Cleaning solvents must be chosen based on the adhesive supplier's recommendation to ensure effective residue removal without damaging machine seals or lines.

3. Process Thoroughness: The established procedure aims for complete residue removal, preventing any leftover material from affecting future production runs or causing blockages.

II. Standardized Five-Step Cleaning Procedure

We recommend following this sequence for an efficient cleaning process:

Step 1: Drain & Prepare
After production, first drain any remaining material from the A and B material tanks. Close the feed valves. Prepare the recommended cleaning solvent (e.g., acetone for epoxy, IPA for silicone) as advised by your material or equipment supplier.

Step 2: Individual Material Path Flush
Pour a sufficient amount of solvent into each A and B tank. Using the control panel, initiate the individual flush cycle for each material path (A and B separately). This allows solvent to circulate through the respective metering pump, valves, and lines until the discharged liquid runs clear.

Step 3: Mixing System Cleanout

• For Dynamic Mixers: Activate the mixer and run the purge cycle to clean the mixing chamber interior.

• For Static Mixers: This step focuses on cleaning the machine's discharge port. The critical action is: Discard the used static mixer tube.

Step 4: System Purging & Drying
After draining the solvent, use dry compressed air or nitrogen to purge both the A and B material lines separately. This step is crucial to remove any residual solvent from the lines and prevent bubbles in subsequent production.

Step 5: Final Check & Reset
Inspect the discharge port for cleanliness. For static mix machines, always install a brand-new static mixer tube. Clean the work area and dispose of used solvent and waste properly.

III. Key Considerations & Professional Advice

• Solvent Selection: Never use unknown or highly corrosive solvents. Follow the "like dissolves like" principle and consult your material supplier for the best option.

• Extended Shutdown: If the machine will be idle for more than 48 hours, after cleaning and purging, introduce a small amount of specific pump oil into the pump chambers to protect critical seals.

• Cured Material: If material cures inside the lines, stop the machine immediately and contact GOOGIO technical support. Do not force operation.

• Maintenance Log: Keeping a log of cleaning dates and solvents used is recommended for tracking and scheduling periodic maintenance.
