From humble beginnings, we’ve grown into a trusted supplier to industries including motorsport, aerospace, medical, oil & gas, and scientific research. Our purpose-built facility in Market Harborough is equipped with advanced CNC turning, milling, multi-axis machining, and wire erosion capabilities — all supported by in-house inspection, assembly, and part marking.

While technology and capacity have evolved, our values remain the same. We’re still proudly family-run, with a hands-on team that’s committed to craftsmanship, reliability, and long-term relationships. Our ISO 9001:2015 and ISO 14001:2015 certifications reflect a deep commitment to quality and environmental responsibility, while our continued investment in equipment, software, and skills ensures we remain at the cutting edge of precision manufacturing.

At MJ Engineering Limited, we’re proud of where we’ve come from — and excited about where we’re going.
