Thermoforming and Vacuum Forming

Industrial Custom Products custom manufactures heavy gauge thermoformed and vacuum-formed plastic parts. We’ve been thermoforming high-quality and reliable parts since 1975, so we’ve got the experience, people, and tech to get it done right, get it done fast.

The Thermoforming Process

Thermoforming is a process where thermoplastic sheets are heated to a pliable temperature, formed to a specific shape using a mold, and trimmed to create a finished product.

Vacuum Forming takes it one step further. When the part is formed to the mold, vacuum pressure is added to assist with the molding of the part. In a nutshell, the plastic is sucked down onto the mold to allow for better detail and consistent thickness. 

ICP also offers Large Part Thermoforming. How large is large? ICP can thermoform parts that are 8’ x 10’ with a 40” draw. We can also form plastic that is up to .437” thick. Now that’s a big piece of plastic!

ICP has broad capabilities beyond just the thermoforming itself. We also work with OEMs to assist in design, materials selection, rapid part prototyping, and manufacturing process efficiency. With our holistic expertise in vacuum forming services, we help our OEM partners meet and exceed their speed-to-market objectives.

Everything We Do Is Custom
We aren’t making run-of-the-mill and off-the-shelf parts. We manufacture custom parts specific to your needs each and every time. Let us know exactly what you want and need, and we will deliver.

Will Thermoforming Produce Cosmetic Parts?
Thermoforming and vacuum forming can be used to create a cosmetic or decorative look. As a vacuum former with years of experience, we can achieve the high-quality aesthetic of other processes but at a lower cost to you than other processing methods.  We can also discuss Pressure Forming for your projects as well.  

Can My Part Be Thermoformed? 
Send us an email with your drawing or CAD attached for our review. We will discuss the manufacturability of the part and whether any changes need to be made to make it formable. We’ve got the real-world experience to analyze designs on a screen and determine how they’ll translate to the manufacturing floor and demands of the market.

Why You Should Choose Thermoforming 
Thermoforming holds many advantages over other processes including injection molding. Some of these advantages include:

  • MUCH lower tooling costs
  • Shorter tooling lead times
  • Faster product development (rapid prototypes)
  • Cost-effective production of large parts 

Add this all up, and you’re well-equipped to meet or exceed your speed-to-market objectives. Spend more time selling your product and less time waiting for it when you choose thermoforming.
