Thermoforming Process

We are glad to share some insights on the process and just how it works.

How Does It Work?

In the process of plastic thermoforming, we start with a roll or thin plastic sheeting. We then pull the material into our thermoforming maching, where it is first heated to designated pliable forming temperature.

Once the appropriate temperature is reached, the material enters the forming station. An upper and lower station clamps down on the material where vacuum and air pressure are used to bring the material in contact with the mold to form the part. 

After being molded, the newly formed part enters the cutting station, where a cutting die is pressed around the part to free the formed part from the unwanted material along the outside of the part. 

Once removed, the parts are stacked until one of our team members removes them for inspection and final packaging. 

Depending on the material and product design, the cycle speeds can vary greatly. Cooling times and product shrinkage also need to be taken into consideration during the design process as both are important factors that can impact the finished product.


The Process Visualized

It never gets old seeing a simple sheet of plastic take shape as it enters one of our thermoforming machines. It’s a fun process to observe and use in applications for our customers.

Thermoforming can be a great alternative to some parts that generally are thought to be produced with injection molding. With a lower tooling cost, thermoforming can be a great solution for your product.

Still not sure if a thermoformed part will work for your application? We invite you to contact us to review your project and determine the best plastic manufacturing process for your needs.

Example Products

Forming Trays

Our customer needed a holding tray for their parts during the cooling process. With tight tolerances around the shape of the finished part, this customer was also able to use our tray for shipping their parts to ensure they were not damaged in shipping and maintained the required shape for the end processor.

Anti-Static Trays

Many customers that purchase anti-static packaging tubes from us also use trays for some of their electronic components. This customer was transitioning their product line and needed a tray solution that was capable of delivering the same level of anti-static/ ESD protection our packaging tubes are known for.  Learn more here.

Clam-Shell Packaging

This customer needed a simple packaging solution that work well with their retail distribution channel. packaging width was critical to ensure it would fit within the designated space and surrounding products.
