Laser Cleaner Minimizes Mold Cleaning Risks

Rocklin Manufacturing Co.’s LC/RR 1500 Laser Cleaner offers a simple, fast and precise alternative to minimize mold cleaning risks. When the 1500-watt fiber laser beam contacts the surface, it interacts with the coating on the mold (but not the mold itself) and then cleans the mold surface by transforming the coating into vapor or dust that then flakes off. This can be done very quickly and since the unit is an all-in-one, portable laser cleaner, can be brought directly to the mold.

When a mold is contaminated with rust, dirt, grease or other substances, it can damage the injection molding process and harm the quality of the molded products. These contaminants can cause surface defects that are then transferred to the molded parts, producing increased mold corrosion and triggering wear and tear on mold surfaces. The mold release process could also be impeded as grease and oil make it difficult for the molded part to separate from the mold, causing lengthy cycle times as well as damage to the part during ejection.

Because the laser can be precisely controlled, this enables selective cleaning of specific areas on the mold. Laser cleaning is a non-contact process, eliminating the risk of wear and tear associated with abrasive cleaning methods. It’s also a dry process that doesn’t require the use of consumables or chemicals that can carry environmental and safety risks.

The laser’s low heat generation avoids thermal damage to molds with temperature sensitivities and the power can be adjusted based on the contaminant type. Moreover, there is no residue left behind and there is an extended life for molds, ultimately alleviating wear and tear in the cleaning process. The fiber laser source can be used for up to 100,000 hours with minimal maintenance required.
