Rainford Precision Machines Limited, a trusted name in ultra-precision engineering since 1991, has now partnered with PEMTec, bringing their groundbreaking Precision Electrochemical Metal Machining (PECM) technology to the UK and Ireland. This advancement offers a transformative alternative to traditional EDM, especially for repetitive features or mass production applications.

Unlike EDM processes, which relies on electrical sparks to erode material, PECM employs a controlled electrochemical reaction, eliminating heat-affected zones, micro-cracks, with no tool wear. **![Computer Numerical Control](https://www.rainfordprecision.com/hs-fs/hubfs/undefined-Oct-23-2025-03-09-41-0237-PM.png?width=405&height=227&name=undefined-Oct-23-2025-03-09-41-0237-PM.png)**   ## **Key Advantages Over Sinker EDM**   ### **Superior Surface Quality & No Thermal Damage** EDM, while precise, can leave a recast layer and micro-cracks due to its thermal process. PECM produces burr-free, stress-free surfaces ideal for mould cavities, reducing or eliminating post-polishing processes. ### **Higher Productivity for Repetitive Features** For high-volume parts (e.g., multi-cavity moulds or textured surfaces), PECM outperforms EDM in speed and consistency. Its multi-electrode setups allow simultaneous machining of identical features, drastically cutting cycle times. ## **Longer Tool Life & Lower Costs** EDM electrodes degrade over time, requiring frequent replacement. PEMTec’s cathodes experience virtually no wear, making the process more economical for long production runs. ## **Exceptional Precision for Complex Geometries** PECM excels in machining thin walls, sharp edges, and micro-features without distortion, a limitation for EDM when handling delicate geometries. ## **Material Versatility** While both methods work on conductive materials, PECM handles hardened steels, titanium, and superalloys more efficiently, with no risk of tool deflection or feed marks. ## **Why This Matters for the Mould & Die Industry** For Mould and Die Manufacturers, PEMTec’s technology is a game-changer: **Injection Moulds**: Achieve flawless cavity finishes, reducing ejection issues and improving part quality. **Die Casting Tools**: Extend tool life with wear-resistant surfaces, lowering downtime for refurbishment. **Micro-Moulding**: Perfect for medical or electronics components where surface integrity is critical. ![Electrochemical Machining (PECM).](https://www.rainfordprecision.com/hs-fs/hubfs/undefined-3.jpeg?width=397&height=250&name=undefined-3.jpeg) ## **Partnering with Rainford Precision** As the exclusive UK/Ireland agent for PEMTec, Rainford Precision combines decades of micro-machining expertise with hands-on support. Their team offers: - Process optimisation for mould tool applications. - Cost studies and test work to prove process capability and quality. - Tooling consultancy to maximise PECM’s advantages over traditional EDM. ## **Next Steps for GTMA Members** To explore how PEMTec can enhance your mould tool production, contact Rainford Precision for a technical consultation. This technology isn’t just an alternative—it’s the future of precision manufacturing. "*With PECM, we’re empowering manufacturers to leapfrog the limitations of conventional machining processes—delivering faster, finer, and more cost-effective solutions for the mould and die sector.*" — Miles Evans, Managing Director, Rainford Precision Machines Ltd.
