The mold is the heart of the molding process and generally 60-70% of mold maintenance is mold cleaning. Traditional methods not only can create extended downtown, because the molds are hot, but can also be ineffective and cause mold wear. This presentation discusses how in-machine mold cleaning, at operating temperatures, can mean the difference between mediocre performance and high-profit productivity.
Dry ice cleaning allows molders to clean while molds are still hot and in the press, significantly reducing downtime due to cooling, disassembly, manual cleaning, re-assembly and reheating. Dry ice cleaning is non-abrasive (protecting the dimensions on parting lines, sealing surfaces, and various surface finishes) and non-conductive, and will not etch or profile most metals. It is also very effective at keeping vents clean for proper air evacuation during molding. Mold release agents buildup, plastic residue and out-gassing can quickly be removed, and intricate, complex shaped molds are easily cleaned with dry ice cleaning.
Because thermoset molded pars have flash, we will also discuss how this flash is easily removed utilizing dry ice. While many parts lend themselves to tumbling, some part geometries do not, and molders find themselves manually deflashing these parts. Dry ice, whether manually performed or an automated system, is very effective at quickly and efficiently removed flash.
This presentation will also briefly discuss the theory and process of cleaning with dry ice as well as the top 5 reasons for considering this solution for mold cleaning and part deflashing: improve quality, lower cost, increase productivity, extend the asset life of the tool, and improve worker safety and the environment by eliminating cleaning chemicals.
