Vacuum Formers & Thermoformers
Vacuum forming is a process in which a sheet of plastic is heated until it is pliable and then stretched over a mold. A vacuum is applied to the mold, which pulls the plastic tightly over the mold, creating a precise shape. Once the plastic has cooled and hardened, it can be removed from the mold.
Top Vacuum Former features:
- Can be used to create a wide variety of products
- Compact and easy-to-use
- Many plastic consumables to choose from

What is a Vacuum Former and Thermoformer?
A vacuum former and thermoformer are both machines used to create plastic parts, custom molds, or products. While they share some similarities, there are also key differences between the two.
A vacuum former, also known as a vacuum forming machine, is a device that uses vacuum pressure to shape thin sheets of plastic material into a specific form or shape. The process typically involves heating a sheet of plastic until it becomes soft and pliable, and then placing it over a mold or template. The vacuum former then uses a vacuum pump to remove the air from the space between the plastic and the mold, creating a tight fit that conforms to the shape of the mold. The plastic is then allowed to cool and harden into the desired shape.
A thermoformer, also known as a thermal forming machine, is a device that uses heat and pressure to form plastic sheets into specific shapes. Unlike vacuum forming, which relies on vacuum pressure alone to shape the plastic, thermoforming typically involves heating the plastic sheet until it becomes pliable, and then pressing it onto a mold or template using a combination of heat and pressure. The plastic is then allowed to cool and harden into the desired shape.
What is a Vacuum Former or Thermoformer used for?
A vacuum former is used to create plastic parts, custom molds, and products by shaping thin sheets of plastic into specific forms or shapes using vacuum pressure. It is commonly used in various manufacturing and fabrication processes, including:
- Packaging
- Custom chocolate making
- Small business applications
- Automotive parts
- Aerospace parts
- Medical components like prosthetics and dental guards
- Letters and logos in signage
- Toys and games
- Various industrial applications
How does a Vacuum Former or Thermoformer work?
A vacuum former works by shaping thin sheets of plastic into specific forms or shapes using vacuum pressure. Here are the basic steps involved in the vacuum-forming process:
- Preparing the mold: The first step in the vacuum forming process is to prepare the mold or template that the plastic will be shaped around. The mold can be made from a variety of materials, including wood, aluminum, or plastic.
- Heating the plastic sheet: A thin sheet of plastic is then heated until it becomes soft and pliable. This can be done using a variety of methods, such as heating lamps, infrared heaters, or ovens.
- Positioning the plastic sheet: The heated plastic sheet is then positioned over the mold, either manually or using an automated system.
- Creating a vacuum: Once the plastic sheet is in position, a vacuum pump is used to remove the air from the space between the plastic sheet and the mold. This creates a vacuum, which pulls the plastic sheet tightly against the mold and shapes it into the desired form or shape.
- Cooling and removing the part: Once the plastic has been shaped, it is allowed to cool and harden into the desired form or shape. The vacuum is then released, and the part is removed from the mold.
How Much Does a Vacuum Former or Thermoformer Cost?
The cost of a vacuum former can vary widely depending on a number of factors, including the size of the machine, the features it offers, and the manufacturer. A small, tabletop vacuum former can cost a few hundred dollars, while a large industrial-grade machine can cost tens of thousands of dollars or more.
Here are some general price ranges for different types of vacuum formers:
- Desktop vacuum formers: These are typically the least expensive type of vacuum former and can cost anywhere from a few hundred dollars to a few thousand dollars. They are typically designed for hobbyists or small-scale production and can be used to create small parts or prototypes.
- Mid-size vacuum formers: These machines are larger and more powerful than tabletop vacuum formers and are typically used for more advanced prototyping or small-scale production. They can cost anywhere from several thousand to tens of thousands of dollars, depending on the size and features.
- Large industrial-grade vacuum formers: These machines are the most expensive type of vacuum former and are designed for high-volume production of large parts or products. They can cost tens of thousands of dollars or more and may require specialized training or expertise to operate.
It's important to note that the cost of a vacuum former is just one factor to consider when choosing a machine. Other factors to consider include the type of plastic materials you'll be using, the size and complexity of the parts you'll be creating, and the level of automation and customization you require.
