PVC Coating: Plastisol Explained

Posted on by carlisleadmin

Plastisol uses a unique formulation process that suspends PVC particles in a plasticizer. The plastic is heated to 177 degrees Celsius, which dissolves both the PVC and the plasticizer. Next, the mixture is cooled to 60 degrees Celsius. This creates a plasticized product that remains permanently flexible due to the dissolved properties of the plastic. Often, this plastic is used for molding various plastic products, but it has a variety of other uses as well including dip coating.

Plastisol is often used in the manufacturing of roof coatings, furniture coatings, screen printing, and textile ink. Plastisol is often used for dip molding, because it coats objects in a flexible coating that is both attractive and durable making it ideal for products such as plastic caps and end tips. Industries use plastisol coatings for a variety of tasks, such as coating tools, protecting surfaces, creating waterproof barriers, and protecting delicate parts from impact.

Surprisingly enough, many of the printed images on modern clothing is created from plastisol coatings melted into the fibers of the fabric. Plastisol is perfect for screen printing because the plastic soaks deep into the fibers of the fabric, allowing the image to stay in place longer. Plastisol will not dry on its own, but requires a curing process to harden the plastic. Plastisol-coated clothing must be cured in an oven before it can be sold in retail locations.

Another popular use for plastisol is as a material for slush molding. In slush molding, the plastisol is placed inside a metal mold, which is then spun rapidly to force the plastic to take on the shape of the mold. The mold is then heated and excess plastic is poured out. This creates flexible, hollow molds perfect for a variety of industrial and commercial uses.

Where Dip Molded Products are Used

Posted on by carlisleadmin

Dip molding is the process of using a metal mold shaped like a finished product and dipping it into plastic product to create an object. Many industries use dip molding, because the dipping process is often less expensive than injection molding or other molding forms. It may surprise you how many different industries use dip molded objects. You can find dip molded products used in the following industries:

Tools: Many tools have dip molded handles. After WWII, manufacturers started replacing wood handles with plastic handles, and the dip mold process is the least expensive form of creating plastic tool handles. Depending on the type of plastic used, the handles can be inflexible or soft to the touch.

Automotive: A surprising number of plastic parts in the automotive industry use the dip molded process. A variety of things, such as tubes, plastic caps, containers, and interior elements of a vehicle are often formed using the dip mold process.

Shoes: Manmade shoes and boots often used the dip molded process. Rain boots, work boots, dress shoes, and some everyday plastic shoes are formed with the dipped mold process.

Plumbing: Many plumbing products use the dip molded method as well. Anything with a hollow inside can be formed through dipped molding. Pipes, pipe fittings, weights, floaters, and other attachments are some of the most commonly dipped plumbing pieces.

Electrical: The electrical industry also uses some dip molded parts. Casings for wires, small plastic screws, rubber gloves, safety equipment, and other parts necessary for electrical work to prevent danger are often created with the dip mold process.

Medical: The medical industry also uses a wide variety of dip molded parts. Catheters, tubes, balloons, masks, gloves, inflatable medical devices, and nearly any other plastic object in the medical industry can be formed using the dip mold process.

Dip Coatings-Your Protection Solution

Posted on by carlisleadmin

Dip coatings are normal used in the industry to protect the surface of objects and quickly apply additional texturing, non-stick coatings, or corrosive-resistant coatings to a variety of materials. Construction, metal working, and the automotive industry all use dip coating. There are specifically three dip coating methods-dip painting, glass coating, and metal coatings. All three offer additional protection on an object while bonding to the surface. They also prevent the coating from wearing off in the normal weathering and usage conditions.

Dip painting is fast and effective at bonding the paint with the base item. With this style, we also see the elimination for the need of spray nozzles. No brushes or manual labor is needed either. Objects are dipped into paint and it is as simple as that. Sometimes the paint is heated to help the paint bond better with the base object. We see this style in coating tools, gloves, metal, and a variety of other materials. We see these materials in both industrial and household uses.

Similarly, metal coatings are applied in the same way as dip painting coatings. A base metal is dipped in chemical baths to prepare it for the coating. Chemicals activate different particles in the metal and help the coating bond better with the base metal. We often see metal coating used to galvanize metal. Additional uses are another coating that won’t come off from washing, weathering, or normal use.

Dip coatings are also applied to glass. Some of the main coatings applied to glass are window tinting and other UV protective coatings that eliminate the passage of UV rays through the glass. Other glass coatings are used to keep the glass from shattering if the glass breaks. We see dipped glass coatings used in the construction of commercial and residential properties. They are also prevalent in the automotive industry and household use. Some common uses are in the construction of glass tables or other furniture.
