Steve Wilson is the Global Business Unit Director for Plastics, Rubber & Composites for Cold Jet, LLC.  As a former plastics business owner he has over 30 years of experience in injection & compression molding, extrusion, blow molding, thermoforming and rotational molding. He began his career at Milacron’s plastics machinery division, serving in manufacturing, product line management and a variety of sales/marketing roles. Steve is a published author and a frequent speaker at plastics industry events. He holds a Bachelor’s degree in Business Administration from Cedarville University and an MBA from Xavier University.


Whether you are injection molding PET preforms or caps & closures, or event blow molding, molds are a mission critical asset and require timely, proper & efficient maintenance to ensure uptime and part quality. Traditional cleaning methods equal extended downtime, and for PET molders, that can equal the loss of over 350,000 preforms/mold clean.

In-machine, dry ice cleaning reduces mold cleaning time that used to be measured in hours to minutes. For example, cleaning lock rings, neck rings, cavities, take out tubes, cores, gate inserts and tapers can be accomplished without disassembly of the stripper plate. The result, increased productivity, better part quality, extended mold life (non-abrasive cleaning), improved worker safety, elimination of cleaning solvents, zero cleaning items going to landfills, all the while, lowering costs.The science, case studies, and how to use dry ice cleaning to improve OEE scores such as Quality Loss, Availability Loss & Performance Loss will be discussed.

The attendee will have a benchmark understanding of how the dry ice cleaning process works, how to implement it in their facility, and eliminate many of the molding problems that are now seeing in their molding process.
