Think You Know Thermoforming?

Thermoforming gives manufacturers the flexibility to create durable plastic components with lower tooling costs and shorter lead times.

But do you know what separates thermoforming, vacuum forming and pressure forming?

Drawing on decades of experience in industrial vacuum forming, we at Donite are setting the record straight on common myths about each process.

Proud of where we’re from. Proud of what we provide.

For over 40 years, we at Donite Plastics have played an active role in Northern Ireland’s manufacturing sector.

From our Saintfield base, we produce high-quality thermoformed components for customers across Northern Ireland and international markets

We support many of the industries that help drive Northern Ireland’s economy, including aerospace, agri-tech, transport and industrial manufacturing. Our thermoformed parts are designed for demanding applications, helping manufacturers here at home and further afield bring their products to market.

When it comes to thermoforming, we’re always in great form – so we are.

Team on the Road: What happens after an exhibition?

Our team spends plenty of time on the road, attending industry events across the country and meeting customers from the sectors we support.

To introduce our new Team on the Road series, we’re doing things back to front. What happens when the stand comes down and we return to our Saintfield base?

We review the questions, ideas and challenges raised at the event, then share them with our design and production teams. Some conversations lead to material and tooling discussions. Others develop into prototypes or full production projects.

One of the regular faces on the road is Alister Heatlie, our New Product Development and Commercial Manager. Alister recently attended Cereals 2026 at Diddly Squat Farm and Hillhead in Buxton.

Reflecting on his time at the events, Alister said:

“June was a busy one for the Donite team. Cereals gave us the chance to show our interior and exterior capabilities, despite the rain and mud. Hillhead brought the opposite weather, but it was great to see Donite parts fitted to several vehicles being launched at the show.

When we return to base, we share those conversations with the wider team and look at what comes next. There really is no ‘I’ in team.”

The stand may be packed away, but our work is only beginning.

Cereals 2026: Two Busy Days at Diddly Squat Farm

Now that autumn is here, we’re looking back at a busy and productive June for the Donite Plastics team.

We had a great time exhibiting at Cereals 2026, held at Jeremy Clarkson’s Diddly Squat Farm in Oxfordshire. The event gave us the opportunity to reconnect with customers, meet farmers, engineers and manufacturers, and discuss the use of thermoformed plastic components in agricultural machinery.

To learn more about our time at Cereals 2026, read our latest blog:

Choosing a material for a vacuum formed component

The right material depends on how the finished part needs to perform.

Before we recommend a material, we look at how the component will be used, where it will be fitted, and what it needs to withstand.

That can include strength, impact resistance, heat performance, thickness, colour and surface texture.

For sectors such as aerospace, transport and manufacturing, there may also be fire, safety or certification requirements to consider.

At Donite Plastics, we can advise customers on material selection as part of the wider vacuum forming process. We look at the application, drawings and end use, then help you choose a material that suits the part and the project.

It is a practical step, but it can make a real difference to how the component performs in production and in use.

For support with vacuum forming, CNC trimming or material selection, contact our team.

The machine that played a major part in Donite’s early vacuum forming operation

Back in the early 90s, we bought our first industrial vacuum forming machine.

Before that, much of our work was in GRP. As demand grew for higher volumes of engineering covers and panels, we needed a process that could support repeat production.

Vacuum forming gave us that.

The first machine came from a company in Manchester, where it had been used to mould suitcases. For us, it marked the start of Donite’s move into industrial vacuum forming.

A wee piece of Donite history: that machine helped us become the first company in Northern Ireland to establish us a vacuum forming company.

A lot has changed since then including the machinery; forming technology has developed, and our capabilities have grown extensively.

Today, from our base in Saintfield, County Down, we support customers across aerospace, transport and the wider industry with vacuum forming, tooling, CNC trimming, finishing, fabrication and assembly.

It started with one second-hand vacuum former.
More than 30 years later, it is a part of Donite’s story.

As a memento, we still have the nameplate of that Handwood machine.

Great to have been part of the ADS Northern Ireland Summer BBQ, with Patrick Knight and Ali Heatlie representing the team.

The event was a great chance to step away from the factory floor and into conversations about future programmes, innovation, and supply chain opportunities across aerospace and advanced manufacturing. Patrick and Ali used the time to reconnect with existing partners, make new introductions, and hear first-hand how ADS community are planning for growth.

As a thermoformed plastics specialist, we're always looking at how our materials expertise can support customers with lightweighting, sustainability, and design flexibility. Being part of the ADS NI and Invest NI wider community helps us stay close to evolving needs and collaborate on new ideas.

Thanks to ADS NI and Sumer NI for creating such a positive setting for not only good food but good conversation.

Where plastic offcuts go after CNC trimming

When a vacuum formed part is CNC trimmed, plastic is often left over from the surrounding sheet.

This can include offcuts and skeletal waste created as each part is trimmed to the right shape, size and finish.

At Donite Plastics, we manage waste as part of our production process, with a focus on reducing waste across our thermoforming and CNC trimming operations.

We also hold ISO 14001 certification for Environmental Management Systems, which supports how we manage environmental responsibilities across the business.
