Product introduction

Fully Automatic Mold Cleaning Machine: Technical Specifications and Application Guide

I. Core Functions 

The lens mold cleaning machine is a specialized machine designed for cleaning molds (e.g., glass, metal molds) in optical lens production. It efficiently removes polishing residues, oil stains, dust, and oxides from mold surfaces, ensuring high surface smoothness to guarantee lens-forming precision and yield rates.

Key Roles:

Extend mold lifespan by reducing contamination-induced defects (e.g., bubbles, scratches).

Improve the substrate cleanliness before lens coating or polishing.

II. Structure and Working Principle

Cleaning Methods:

Ultrasonic Cleaning: High-frequency ultrasound (40kHz–100kHz) removes microparticles via cavitation effects.

Spray Cleaning: High-pressure spray system (water-based or solvent cleaners) flushes mold surfaces.

Vapor Phase Cleaning: Solvent vapor (e.g., IPA) dissolves stubborn contaminants.

Core Components:

Cleaning Tanks: Corrosion-resistant (SUS304 stainless steel), multi-tank workflow (clean → rinse → dry).

Filtration System: Multi-layer filters (5μm–50μm) recycle cleaning fluid for extended use.

Drying Module: Hot air or vacuum drying to eliminate watermarks.

IV. Application Scenarios

Optical Lens Production: Post-polishing cleaning of glass/resin molds to remove resin residues or polishing powder.

Precision Mold Maintenance: Rust prevention and oxide removal for metal molds (stainless steel, nickel alloys).

Pre-Coating Treatment: Ensures contaminant-free surfaces to avoid pinholes or coating delamination.

5、our company has nearly 20 years of experience in technical and after-sales service team, from design and production to after-sales service to provide customers with professional solutions.

VI. Selection Guide

By Mold Material:

Glass Molds: Low-frequency ultrasound (40kHz) + soft brushes to prevent scratches.

Metal Molds: High-frequency ultrasound (≥68kHz) or spray cleaning with acidic cleaners (anti-corrosion required).

By Contamination Level:

Light Contamination (e.g., polishing powder): Single-tank ultrasonic cleaner + deionized water.

Heavy Contamination (e.g., cured resin): Multi-tank system (ultrasonic + spray + vapor cleaning).

Optional Features:

Automation: Robotic loading/unloading (ideal for mass production).

Eco-Friendly: Integrated wastewater recycling and treatment.

VII. Operation & Maintenance

Cleaner Selection:

Water-Based Cleaners: Eco-friendly for general oil removal (e.g., lens polishing agents).

Solvent Cleaners: IPA, acetone (high efficiency; requires explosion-proof design).

Maintenance Routine:

Daily: Clean tank residues; inspect filter clogs.

Monthly: Test ultrasonic transducer power; calibrate temperature sensors.

Precautions:

Avoid mixing incompatible cleaners (e.g., acidic + alkaline).

Use soft fixtures for glass molds to prevent breakage.

VIII. Summary

The lens mold cleaning machine is critical for ensuring optical lens quality. Selection must account for mold material, contamination type, and production scale. High-frequency ultrasonic technology and automation are driving industry trends, with future advancements prioritizing intelligence and sustainability.
