Preventive maintenance is a daily activity at Gavco Plastics. We have 4 to 7 mold changes daily, and when these molds come out they are taken to our tool shop to be looked over and prepared for storage and the next run. Date codes, Revision changes, insert changes is a normal daily routine. All tools are treated with a rust prohibitive treatment after each production run. Whether it is an aluminum mold for small quantities or P 20 steel for millions of parts, every tool receives preventive maintenance care at our facility.
