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.

Our Plasma Cutting Capabilities

At our Midlands facility, we operate a range of state-of-the-art plasma cutting machines that allow us to deliver flexible solutions across a wide variety of projects.

Our twin-headed 460 Amp system is designed for large-scale work, offering a cutting bed size of 16,000mm x 5,000mm. Alongside this, we run a single-head 300 Amp machine with a 10,000mm x 2,500mm bed and a Gemini machine with a 7,000mm x 2,500mm bed, giving us the versatility to handle both heavy and light plate work with consistent accuracy. This combination of equipment ensures we can take on everything from straightforward profiles to intricate, high-tolerance components.

This setup allows us to deliver exceptional quality for all your steel component needs, while maintaining quick turnaround times and competitive pricing.

Why Choose RMP Products for Plasma Cutting Services

Our plasma cutting service operates around the clock, seven days a week, ensuring you receive your HD plasma cut parts as quickly as possible with a maximum turnaround of fourteen days.

Thicker Steels Advantage

For thicker steels, CNC plasma cutting offers outstanding precision and cost efficiency compared to laser cutting, performing at its best between 6mm and 38mm.

Certifications & Quality Guaranteed

We are ISO 9001 certified and fully compliant with UKCA Execution Class 4, demonstrating our commitment to the highest manufacturing standards. Every plasma cut part is thoroughly inspected to ensure it meets your industry requirements.

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.

What is the maximum thickness that can be cut using plasma?

Our equipment effectively cuts materials up to 75mm thick, with optimal quality achieved in the 1mm to 60mm range.

How accurate is plasma cutting?

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

What is the difference between standard and HD plasma cutting?

HD plasma creates a more focused arc that produces cleaner cuts with less bevel and higher precision than standard plasma.

What information do you need to provide a quote?

Material specifications, quantities and any specific tolerance requirements.

How clean are the plasma cutting edges?

Modern CNC plasma cutting machines offer high precision and clean edges with minimal dross (residue) on steel. However, the cut quality can depend on factors such as material thickness, machine settings and cutting speed.
