Often, when metal components feature rough edges, finishers apply a liquid plastisol coating. In Grand Rapids, this is a common practice for certain components. The process is used to coat wire racks, tool and gas pump handles, fencing, gym apparatus and playground equipment. The coating provides the metal objects with certain qualities necessary to ensure the satisfying of aesthetic and functional needs.
By employing plastisol, manufacturers are providing their customers with products featuring high levels of corrosion resistance. At the same time, metal, plastic, glass, and ceramic objects look better and are more comfortable. For example, coating tool handles make them easier to use without interfering with the overall functionality.
Methods Used to Apply Liquid Plastisol
Plastisol is applied in liquid form. The actual method for doing so differs. While dipping is preferred in many Grand Rapids finishing shops, the type of plastisol dipping varies. Among the three most common are the following:
1. Dip Molding: This utilizes either a hot or cold dip process. After dipping, whether hot or cold, the object must then undergo curing. This involves heating the items until the liquid plastic solidifies.
2. Slush Molding: The procedure is very similar to dip molding. It includes dipping followed by the part being placed in a centrifuge. This ensures the plastisol falls into and coats every corner, dip or other complex geometric feature. Curing follows.
3. Spray Coating: If the coating is to be thin, operators use a gun filled with liquid plastisol onto the surface of the workpiece. Curing follows.
Liquid Plastisol
Coating an item with liquid plastisol helps to improve its longevity. This is particularly true if the product is placed outdoors. Its ability to resist corrosion is one reason many fences in Grand Rapids MI are coated with plastisol. By using this process on their products, companies are improving its insulating properties as well as abrasion resistance, protection against various chemicals and UV light, and overall durability.
