Cleaning quickly and economically, while remaining conscious of environmental and production regulations can be a challenge, the use of plastic media in pneumatic dry blast equipment provides an answer to that challenge. Plastic media has the ability to clean rapidly without damaging surfaces. Intricate components and soft materials are not eroded with plastic media blasting. Additionally, plastic media consists of fully cured, non-toxic, thermoset
Type III Plastic Grit
compounds, which means that there is no threat to the work environment and the dry waste isn’t a hazard to dispose. Guyson carries many forms of plastic media; we offer three forms of plastic grit. Type I (the least aggressive and softest), Type II (Urea, which is harder and more durable than Type I), and Type III (Melamine, the hardest and most aggressive of the plastic media). We also work with Polystyrene Bead, Polycarbonate Bead, Nylon Bead, and Acrylic Plastic Grit. Applications include de-burring of machined parts, de-flashing plastic or aluminum cast components, mold & die cleaning, reconditioning, hard deposit cleaning, as well as the removal of surface oxidation and paint from a wide range of materials including delicate plastic parts, aircraft aluminum, engines, iron, and steel.
Walnut Shell
Similar applications involve the use of natural or agricultural media; Guyson carries Walnut Shell, Corn Cob, and Apricot Pit. Walnut Shell is a soft angular biodegradable media that is used to clean and remove superficial deposits without causing damaging effects on underlying material. Corn Cob is a soft, low-density, renewable grit material that is not abrasive, making it suitable for light blasting without modification of delicate substrates. Apricot Pit is an angular shell material, slightly softer and lower in density than walnut used for similar gentle cleaning and non-aggressive blasting. Applications for natural media include mold and die cleaning, light de-burring, de-flashing, reconditioning, cleaning light surface deposits, light coating removal, and the cleaning of soft metals, fiberglass, and wood.
While both natural and plastic media have their advantages, plastic media typical yields much faster and complete stripping. Plastic media also retains its sharp edges throughout its life, while natural media such as walnut shell will round off and stop cutting. Plastic media will strip at approximately 4 times the speed of natural media and its life cycle is typically 4-5 times longer.
Typically natural media can be used in aircraft and automotive stripping as well as marine turbines.With plastic media it is commonly used in aerospace and automotive blasting applications as well as paint, coating and carbon removal. Mold, die and tool cleaning. Removal of light flash from die castings or burrs from machined parts. Deflashing of electronic components.
