RapidMade | Vacuum Forming For Industrial And Automotive Applications

Are you finding it tough to source a cost-effective and efficient way to manufacture precise, high-quality parts for your industrial or automotive projects? We understand how challenging this can be; we’ve encountered the same hurdles.

One key insight we’ve discovered is that vacuum forming offers a faster tooling production process compared to other methods, significantly speeding up your manufacturing timeline.

Through careful research, we’ve found that modern vacuum forming techniques can greatly enhance both the quality and efficiency of part production. In this blog, we’ll walk you through understanding what vacuum forming entails, its processes, the materials involved, and why it’s advantageous for industrial and automotive applications.

Understanding Vacuum Forming

RapidMade | Vacuum Forming For Industrial And Automotive Applications

Vacuum forming shapes plastic into useful forms. The process uses heat, molds, and vacuum pressure.


We begin the vacuum forming process by heating a thermoplastic sheet until it becomes soft. This step is crucial, as the plastic needs to be pliable for shaping. Next, we place the heated sheet over a mold.

The mold can be simple or complex, depending on what shape we need.

After placing the sheet over the mold, we create a vacuum underneath it. This suction pulls the softened plastic tight against the mold’s surface, allowing us to form intricate details.

Once shaped, we cool and solidify the plastic before trimming away any excess material. Finally, finishing touches ensure that each piece meets precise specifications.

Vacuum forming allows us to produce high-quality parts quickly and efficiently.

Materials and Equipment

Understanding the vacuum forming process gives us a good foundation. Now, let’s dive into the essential materials and equipment pivotal to this technique.

We primarily use thermoplastic sheets in vacuum forming. Common materials include ABS, PVC, acrylic, and polycarbonate. These plastics are heated until they become pliable. Once soft enough, we place them over molds designed for specific shapes or parts.

Vacuum forming machines vary in size and complexity but share core components: a heating element, a frame to hold the plastic sheet, a mold table, and a vacuum pump. The heating element warms up the plastic evenly while the frame keeps everything secure during shaping.

For industrial applications, such as automotive thermoforming or packaging production, we often utilize  vacuum presses. These machines offer precise control over temperature and pressure settings which ensures accurate shapes every time.

Our tools must also accommodate different sizes of molds—from small items like electronics casings to large objects like car body panels. Proper cooling systems help solidify formed plastics quickly without defects.

Consistent maintenance of our equipment is crucial too. Regular checks ensure that all parts function correctly—ensuring efficiency in manufacturing processes from start to finish.


To get the best results in vacuum forming, we use a few key techniques. One important method is plug assist forming. This technique helps stretch the plastic sheet evenly by using a shaped plug before applying the vacuum.

It ensures uniformity and reduces thinning of material in critical areas.

Another effective technique involves using twin-sheet forming. In this process, two plastic sheets are heated and formed at once on separate molds. They come together to form hollow parts with complex shapes, which are perfect for automotive or industrial applications needing reinforced structures.

This method provides strength and precision without adding too much weight to the final product.

Steps of the Vacuum Forming Process

The vacuum forming process has several steps that ensure precise shaping of materials. First, we heat a thermoplastic sheet until it becomes soft and pliable… then we begin molding.

Heating the Thermoplastic Sheet

We start the vacuum forming process by heating a thermoplastic sheet. This plastic sheet gets soft and flexible under heat. The temperature must be just right—hot enough to mold but not so hot that it melts.

Our ovens use precise controls to achieve this perfect temperature. We watch the plastic carefully during this step. Uneven heating can ruin the final product, making evenness key for high-quality results in industrial and automotive applications.

Placing the Sheet over the Mold

The heated thermoplastic sheet becomes soft and pliable. We must quickly place it over the mold. This step is crucial to ensure the plastic fits perfectly around every contour of the mold.

Next, we make sure the sheet covers all areas evenly. An uneven placement can cause defects in the final product. Industrial vacuum forming machines often have automated systems to help with this precision, making our job easier and more efficient.

Creating the Vacuum

We place the heated sheet over the mold. Next, we create a vacuum to shape it. This step is crucial for forming precise shapes in automotive and industrial applications.

We use specialized pumps to remove air between the plastic sheet and the mold. This causes the material to conform tightly around all details of the mold. Vacuum forming technology is valuable here because it ensures sharp angles and complex curves fit well—key features for detailed parts like car dashboards or equipment housings.

Cooling and Solidifying

Cooling is crucial in vacuum forming. After shaping, the plastic must harden to maintain its form. Air cools it quickly, and fans can help speed up the process.

Solidifying ensures that parts stay strong and durable. We use cooling systems to prevent warping or bending during this stage. Proper cooling results in high-quality products for industrial and automotive applications.

Trimming and Finishing

Trimming and finishing are crucial steps in  vacuum forming. We start by removing excess material from the formed part with precision tools. This ensures accurate shapes matching detailed industrial and automotive requirements.

Next, we focus on finishing to smooth out edges and surfaces. Techniques like sanding or polishing guarantee a high-quality final product. These steps enhance the durability and look of thermoformed parts used across industries such as manufacturing, electronics, and medical sectors.

Applications in Industrial and Automotive Sectors

Vacuum forming is used to make car parts, packaging, medical devices, and toys. This process helps create strong and lightweight products for different industries.


Packaging plays a crucial role in protecting products during transportation. By using vacuum forming, we can create sturdy and custom-fit packaging solutions. This method helps keep items safe from damage.

In industrial settings, plastic trays or containers made through this process ensure parts are held securely. It also offers flexibility for creating different shapes and sizes. In the automotive sector, specialized forms help transport car parts without scratches.

Automotive parts

We use  vacuum forming to create precise automotive parts. This method shapes plastic sheets into detailed forms using a vacuum. It’s fast and cost-effective compared to other methods like injection molding.

Our process produces items such as dashboards, door panels, and bumpers. These parts fit perfectly and perform reliably in vehicles. The technology lets us make both small components and large body panels with ease.

Let’s continue using these innovations for better, more efficient production in the automotive industry.
