Thermoforming is a cost-effective way to make molds for plastic. Vacuum forming is a thermoforming technique that involves heating and vacuum pressure being applied to a plastic sheet to form the case or part. Several thicknesses of plastic are available, and the completed component or case may provide outstanding toughness.

Some of these include acrylic, low-density polyethylene (LDPE), high-density PE (HDPE), PP, and crystalline polymer credits or CPET. Vacuuming forms the shape into an object while simultaneously melting it away at its softened state so there’s no risk for warping due to both surfaces being heated equally intensely inside as well outside; this method also allows designers who may not have access to other tools like laser cutters because they’re too expensive -or even know-how-, to produce certain types of objects.

The benefits of vacuum thermoforming include versatility, precise control over shape and thickness, and the ability to produce large quantities quickly and efficiently. Additionally, vacuum thermoformed parts are typically strong and durable, making them ideal for use in a variety of applications. If you’re looking for an efficient and versatile way to manufacture plastic parts, then vacuum thermoforming may be the perfect solution for you and your business. 

A Breakdown of the Thermoforming Process

Have you ever seen those colorful, plastic trays that are often used to hold food? Those trays are made through the thermoforming process. This manufacturing process uses heat and pressure to shape plastic into desired forms. 

Thermoforming is not only used to create trays, but also bowls, cell phone cases, cups, and lids. This process is versatile in the sense that it can produce a variety of items with different designs for different types of businesses. 

The thermoforming process begins with the heating of sheet plastic until it becomes pliable and ​is a three-step process. 

  1. The first phase of production begins with the plastic sheet being heated, in order to soften it.
  2. In the second phase, the heated sheet of plastic is drawn tightly over a mold using mechanical assists, direct pressure, or vacuum to form the material. A type of thermoforming that employs this technique uses heated playlists pulled taut against your desired shape by an external source. Forming removes all air between the mold and the plastic sheet, resulting in negative air pressure that draws the plastic down onto a thermoforming mold. 
  3. The molded plastic is then cooled on either the tool that created it or transported to another station where they finish cooling. Once cool, this formed piece can be operationally used for installing valances and locks among other hardware, or it can be painted and shipped to automotive manufacturers for installation in car doors, trunks, and roofs.

Why Should Call On Plastiform Inc for Your Vacuum Thermoforming Needs? 

Vacuum thermoforming is a manufacturing process that utilizes vacuum power to create plastic containers. It’s an inexpensive way for companies on tight budgets to produce quality products without the high production costs associated with injection molding or blow molding. The only drawback is that it can be difficult to work with due to material limitations, lack of flexibility, and slow speeds in comparison to other processes. 

When looking for a company to provide thermoforming services, it is important to do your research in order to ensure you are getting the best possible product and service. Plastiform, Inc. is a leading thermoformer with many years of experience providing high-quality products and services to customers across a wide range of industries.
