Laser Cleaning Specific Applications:

A. Residue in Complex Geometries

Deep Holes and Threads: Rubber can penetrate screw holes, ejector pin holes, and threaded structures in the mold under high-pressure injection, making it extremely difficult to remove after curing.

Narrow Grooves and Sharp Angles: Rubber residue is tightly squeezed into mold seals, snap-fit structures, and other areas, making it inaccessible to physical tools.

Curved Surfaces and Undercuts: Irregular curved surfaces and undercuts make it difficult to achieve uniform cleaning with traditional methods.

B. Contamination on Fine Surfaces

High-Gloss Surfaces: For molds requiring a high surface finish, even the slightest residue or scratch can affect the product’s appearance.

Etched Textures: Some rubber parts require a non-slip texture, and these grooves are easily clogged with rubber residue.

• Stubborn Vulcanized Contaminants: During the high-temperature vulcanization process, rubber, together with release agents and additives, forms a hard, dense carbonized contaminant layer on the mold surface, making it difficult to completely remove with conventional cleaning.

Specific Advantages:

Penetrating and Thorough Cleaning: The laser’s linear propagation allows it to easily penetrate narrow gaps, deep holes, and complex textures, achieving comprehensive cleaning. Whether it’s the spring grooves of an oil seal mold or the snap-on teeth of a sealing strip mold, they can be cleaned to like-new condition, fundamentally ensuring the dimensional accuracy and appearance quality of custom-shaped parts.

• Absolutely Non-Destructive Cleaning: The cutting edges, mirror surfaces, and textured surfaces of custom-shaped molds are extremely valuable and fragile. The laser’s non-contact nature ensures: Preservation of delicate edges: No blunting or damage to the cutting edges caused by physical contact. Maintaining Texture Consistency: Dirt within the texture is thoroughly removed without damaging the texture itself, ensuring a consistent surface finish. Maintaining Mirror Gloss: Zero wear on polished surfaces, leaving the mold looking like new after cleaning.

C. Improving the Quality and Consistency of High-End Products: Thorough cleaning means: Avoiding Shortages: Clean flow channels ensure smooth rubber filling, preventing product shortages caused by blockage. Stable Demolding: Highly clean surfaces ensure smoother demolding, reducing the need for release agents and improving product surface quality. D. Green and safe, protecting employee health: Special-shaped molds have complex structures. After chemical solvent cleaning, residual solvent vapor is more difficult to evaporate in the gaps, posing a threat to subsequent products and employee health. Laser cleaning eliminates this risk at the source.
