Key Terminology Used

Thermoplastic forming uses specific terminology and if you’re unsure on what certain terms mean, here’s a quick guide to the different phrases used within the thermoplastics industry.


This refers to a style of plastic made from polymer that becomes mouldable at a certain temperature and solidifies when cooling.


This is a general term which describes the process of transforming a sheet of plastic into a three-dimensional shape by using heat, vacuum and pressure.

Vacuum forming

This process involves forming a part by heating and stretching plastic across a mould using a vacuum. For a more detailed explanation on the vacuum forming process, check out our Vacuum Forming Guide.

The Thermoplastic Forming Process

Our thermoplastic forming process works by heating a sheet of thermoplastic then stretching and manipulating it across a mould to give it the desired shape. Thermoplastic moulding transforms the plastic sheet into a 3-dimensional shape and then the forming process allows the plastic to conform  to its final shape before the product is finished and trimmed.

The Benefits of Thermoforming

The specific advantages of the thermoforming process involve aspects such as:

  • Size Versatility – Thermoforming allows for the manufacture of larger and smaller plastic components which can be useful across a number of sectors.
  • Cost Effective – Many companies and businesses across a multitude of sectors choose the thermoforming process as it is more cost effective than other methods of plastic moulding such as injection moulding. This is mostly due to the fact that a large part size would commonly mean a high tooling cost.
  • Reliable – Thermoforming has been a staple of plastic component manufacturing for a while now and has been tried, tested, and adapted to ensure that it is an effective and safe method of manufacturing plastic parts and components.
  • Adaptable – The thermoforming process is easily adaptable to a number of applications and allows for easy customisation of products if required which can be a major advantage.

5 Axis CNC

Make to Print

Make to print plastic components are where they are designed, materials specified and tested by your company. The supplier only becomes involved solely to manufacture the products to the specification requested and will have no other input on the design or testing of the plastic components.

The make to print process is suitable for a variety of plastic parts which can range from small mass produced pieces to larger, more unique projects. Our make to print parts can be manufactured through the vacuum forming or thermoplastic forming process.

Furthermore, our make to print plastic components are finished to a high standard by one of our eight, industry-leading, Maka 5 Axis CNC machines which can meet even the most complex machining and trimming requirements.

Thermoplastic Materials Mould

Materials Used in Thermoplastic Forming and Moulding

There are many different materials that can be used when forming or moulding thermoplastic and the best materials are selected based on the products primary function. Types of plastic used include Acrylic, Polypropylene, Polyethylene, Polyetherimide and PVC.

Thermoplastic forming can be used with a variety of different materials, depending on the requirements of the specific project.


A clear material that is abrasion resistant. Easy to fabricate and is available in impact-modified grades and multiple colours.


A material with excellent chemical resistance. It’s rigid and has a good impact strength and works well at higher temperatures; however, dimensionally, polypropylene is not as stable as other materials.


Commonly used for packaging such as plastic bags, plastic films, containers and bottles. It’s a clear material which is low cost to manufacture.


A very high temperature grade material with a natural amber colour


A strong and rigid material with a good impact strength. PVC is also flame-resistant but its usability is restricted.

Any products that require a decorative finish can be manufactured using a pre-printed thermoplastic or can be achieved through post-moulding printing. Whatever the product or specification, we can advise on the best approach to get the most from your design concept by using the most effective process of manufacturing.

Thermoplastic Quality

Quality Assurance

Although the core sectors we supply are automotive and aerospace, the same high quality standards are applied across every single product we produce, regardless of the industry.

As an ISO 9001:2015 certified company, we streamline our thermoplastic forming process to cut down any unnecessary cost or wastage from the manufacturing process, ensuring that you get the highest quality of product at the most competitive rate.
