Thermoforming

Custom Plastic Fabrication Using Vacuum Forming & Line Bending

At PAR Engineering, we offer thermoforming services designed to turn plastic sheets into functional, shaped components with efficiency, accuracy, and visual consistency. Using vacuum forming and line bending, we produce a wide range of parts and products — from protective panels and display trays to machine housings, covers, and retail fixtures.

Whether you’re creating a prototype or scaling up for production, our in-house team works closely with you to deliver high-quality, made-to-measure plastic components — fast.

What is thermoforming?

Thermoforming is a plastic manufacturing process where flat thermoplastic sheets are heated to a pliable temperature, then formed into specific shapes using moulds or manual manipulation. Once cooled, the material retains its new shape permanently.

Why Choose PAR?

From Sheet to Shape — Designed, Formed, Finished, Delivered

Whether you need clear display panels, custom trays, or protective housings, our in-house team supports your thermoforming project from design through to delivery. With precision equipment, plastic expertise, and fast turnaround, we help you go from concept to final product — all under one roof.

CAD Design

Our in-house design team work with 2D and 3D Computer Aided Design software to capture your product requirements and
provide a detailed render for sign off.

Product Prototyping

Our in-house team work from product design through to delivery, our production team use their decades of experience and knowledge to engineer your bespoke prototype products.

Plastic Cutting

We use our CNC Machine to cut complex shapes from sheet plastics, from PETG and ABS through to Polycarbonate and Acrylic.

Finishing

From CNC trimming to edge polishing and packaging, we deliver ready-to-use products — clean, consistent, and on time.

Vaccuum Forming

Vacuum Forming is a popular thermoforming technique where a heated plastic sheet is drawn over a mould and then a vacuum created, sucking the plastic sheet tightly into the mould, once the material cools, the moulded shape is then retained.

This method of thermoforming is used to create lightweight, repeatable components with a smooth and professional finish.

We often use vacuum forming for a variety of products, however commonly it is used for the following;

Protective Covers
Plastic Inserts and Trays
Enclosures and Housings
Control Panel Surrounds

We work with a variety of materials such as HIPS, ABS, Polycarbonate, PETG and Acrylic.

Line Bending

Line Bending is another thermoforming technique, however, for line bending we heat a section of the sheet and then bend the sheet to the desired angle and shape. This allows us to produce crisp folds and curves in the material.

Line Bending is commonly used for the following applications;

Machine Guards and Panels
Point of Sale Displays
Desk Dividers
Edge Trims and Sign Panels
