CNC Plasma Cutting Service | Steel HD Plasma Cutting UK

HD Plasma Cutting Service

We provide precision CNC plasma cutting services for carbon and mild steel across the UK, delivering highly accurate and detailed components in material thicknesses from 6mm up to 60mm plate. Plasma cutting is an efficient and cost-effective solution for profile cutting, making it ideal for both thinner and thicker steel applications. With plasma cutting beds capable of handling up to 16 metres in cutting length and 5 metres in cutting width, we can accommodate everything from small, intricate parts to large-scale plasma cut profiles.

As specialists in HD plasma cutting, our facility is equipped with the exclusive Viper Twin Head XPR460 plasma cutting machine, featuring an impressive 16,000mm x 5,000mm cutting bed. This is complemented by a 300 Amp single-head machine with a 10,000mm x 2,500mm bed and a Gemini machine with a 7,000mm x 2,500mm bed. This combination of advanced CNC plasma cutting equipment allows us to efficiently process both heavy and light plate work while maintaining consistent accuracy and repeatability.

Whether you require a one-off prototype, a small batch, or high-volume repeat production, our advanced plasma cutting technology delivers parts precisely to specification. Operating to ISO 9001 quality standards and UKCA Execution Class 4 certification, we ensure every plasma cut component meets the highest industry requirements and performs exactly as intended for your project.

Over 30 Years of Expertise in Plasma Cutting

Offering high-precision CNC plasma cutting services for steel components with fast turnaround, certified quality and expert support across the UK.

Benefits of Plasma Cutting

Exceptional Cutting Speed: Plasma cutting operates significantly faster than traditional methods such as flame cutting, with cutting speeds up to four times quicker. This increased efficiency helps reduce project lead times and lowers overall labour costs.
Versatility in Material & Thickness: Capabilities of cutting a range of electrically conductive metals from mild steel cutting to aluminium and copper. It performs particularly well when cutting medium thickness plates, with capacities of up to 60mm.
High Cut Quality: Modern high definition plasma cutting systems deliver excellent accuracy, achieving tolerances as tight as plus or minus 0.25mm. This results in clean, sharp and narrow cuts with a consistently high finish.
Cost-Effectiveness: Cost Effectiveness: For thicker materials, plasma cutting is often more economical than laser or waterjet cutting, particularly for material thicknesses above approximately 15mm. Plasma cutters also work directly from CAD drawings, optimising material usage and helping to reduce waste.

Plasma Cutting Project (JCB)

Overview

JCB needed a faster and more cost effective way to produce large telehandler side plates measuring 5 metres by 1.5 metres. Their existing process required multiple operations across different machines, leading to long lead times and high handling costs.

Our Solution

Using our Gemini combined machining and plasma cutting system, we completed every stage of the process in one setup. All holes were machined and tapped, the plate profile was plasma cut, and then chamfered the large hole. This removed the need for external machining or manual finishing.

Results

JCB received fully finished parts with shorter lead times, reduced costs and consistently high quality. The streamlined process enabled them to keep pace with production demand.

Plasma Cutting FAQs

What types of steel can be cut using plasma cutting?

We specialise in cutting mild steel, carbon steel and stainless steel in various grades and thicknesses.

How accurate is plasma cutting?

Our CNC plasma cutting delivers high precision with tolerances typically within +/-1.5mm/2mm depending on material thickness.

What are plasma cutting services?

Plasma cutting uses a high-temperature, electrically conductive plasma arc to cut through electrically conductive metals such as carbon and mild steel. The process delivers fast, accurate profile cutting and is particularly effective for both thin and thick plate applications.

Which is better, plasma or laser cutting?

Plasma cutting is generally better for thicker materials and cost-effective production, while laser cutting is better suited to thinner metals where a higher level of precision and edge finish is required.

What cannot be cut with a plasma cutter?

A plasma cutter cannot cut non-conductive materials such as wood, plastic, glass, ceramics or composites, as the process relies on an electrical arc to cut electrically conductive metals only.

How thick can plasma cutters cut?

Depending on the machine and power output, plasma cutters can typically cut metal from thin sheet up to around 60mm thick, with industrial systems capable of cutting even thicker materials.
