Application of Qingdao Newtep Dry Ice Cleaning Machine in Injection Mold Industry

Traditional cleaning methods are not only time-consuming and labor-intensive, but also damage the mold itself and affect its accuracy.

Sandblasting

It will wear the mold; and cause secondary pollution.

Water wash

It is easy to cause rust; conduct electricity; and the washed sewage produces secondary pollution, which must be treated.

Solvent cleaning

It is corrosive to a certain extent and damages the mold; it is not good for the operator`s health; it produces electrical conductivity and has safety hazards; it produces secondary pollution.

Manual cleaning

Extend downtime, low efficiency; unfavorable to the operator`s health; conduct electricity and have safety hazards; produce secondary pollution; easily damage the mold.

Dry ice: solid CO2

Physical properties: low temperature (-78.5 degrees Celsius), easy to sublimate

The dry ice cleaner sprays solid dry ice particles (3MM) onto the surface at high speed

Impact microburst

Dry ice particles impact the surface at a high speed and burst into gas instantly, resulting in micro-explosion.

Thermal expansion and contraction

Dry ice hits the surface instantly, and the stain shrinks due to cold, making it easier to peel off the surface.

Air wave purge

The sublimation volume of dry ice expands by about 800 times, and the powerful air wave blows away the stains, achieving dry and residue-free cleaning.

Comparison of Qingdao Newtep Dry Ice Cleaning and Traditional Cleaning Methods

• Improve product quality
• Reduce scrap products and increase yield rate
• Shorten downtime
• Shorten cleaning time and reduce labor costs
• Online cleaning without disassembly
• No wear or damage to the product or mold
• No secondary pollutants
• Environmental and harmless

1. Efficient

Traditional cleaning requires disassembly, cooling, cleaning, and reassembly;

On-line cleaning, no need to disassemble the equipment; improve efficiency and ensure equipment accuracy.

2. Thorough

Traditional cleaning is difficult to clean corner gaps, high precision, complex structure molds;

Effectively clean corners, gaps, and dead ends; no pollution, no residue, and environmental protection.

3. Lossless

Traditional cleaning, grinding, soaking and other methods damage the mold, reducing accuracy and product quality;

The intensity of dry ice cleaning can be adjusted arbitrarily, which will not damage the mold and the product, prolong the service life of the mold and improve the quality of the product.

4. Dry

Traditional cleaning will use water, solvents, etc., resulting in electrical conductivity, residues, etc.;
Dry ice cleaning can touch the electrical parts, non-conductive, non-corrosive, and non-rusty.

5. Environmental protection

Traditional cleaning uses water, solvents, etc., which have an impact on human health, and at the same time cause secondary pollution to the environment, and increase the cost of secondary pollutants treatment;

Dry ice cleaning avoids secondary pollution, is non-toxic, odorless, and has no residue, and dry ice is a recyclable and renewable resource and is environmentally friendly.
