What Kemlows Diecasting Products does

Kemlows Diecasting Products Ltd is a UK-based, privately held high pressure die casting foundry founded in 1946 by Charles Kempster and William Lowe, originally producing diecast miniature toys in London before relocating in 1974 to its current purpose-built facility in Hoddesdon, Hertfordshire. Since 2001 the company has been owned by the Teoli family, who have repositioned it as a precision engineering supplier focused on larger, higher-value cast components. The business operates 7 aluminium high pressure die casting machines (Buher and Frech, 125-840 tonne locking force) and 3 zinc hot chamber machines, supported by a 12-CNC-centre machine shop opened in 2011, an in-house toolroom, component design capability using CAD and PiQ2 3D flow simulation, and finishing/assembly operations. Differentiated process features include vacuum-assisted casting for low porosity, automated drossing/degassing, and precise shot profile control.

The company serves enterprise B2B customers through a direct sales model managed by an in-house Business Development/Sales Manager, quoting project by project. Customer verticals are Automotive (primary, IATF 16949:2016 certified, including Tier 1 suppliers), Medical devices, and a broad General Engineering basket spanning telecommunications, white goods, electronics, marine, garden equipment, hand tools, and racking. Geographic reach covers the UK, continental Europe, and the United States. Quality is underpinned by BS EN ISO 9001:2015 and IATF 16949:2016 certifications, with inspection equipment including YXLON MU2000 X-ray, Aberlink Horizon 1500 CMM, and GNR Mini Lab spectrometer. Revenue is generated through custom, quote-based contracts with no public pricing; the company employs 11-50 staff and operates a continuous capital reinvestment cycle that has added new die casting cells, CNC machines, toolroom equipment, and inspection systems roughly every 1-2 years since 2014.
