MICRO PLAS MOULDINGS LTD

What MICRO PLAS MOULDINGS LTD does

Micro Plas Mouldings Ltd (MPM) is a UK-based private limited company specialising in bespoke injection moulding, tool making, and product development. Founded approximately in 1996 by Giovanni Nieddu in Waterlooville, England, the company operates a sales and administration office in Midhurst, West Sussex and a manufacturing facility in Portsmouth, Hampshire. MPM provides end-to-end plastic product development services — from concept and design consultation, through materials selection, prototyping, and tool manufacture, to production injection moulding — alongside a portfolio of four proprietary branded product lines: Sperm Keyrings (promotional items for sexual health and fertility campaigns), Roto-Lite (wind-powered hazard reflectors for traffic cones), Kinetic Ram (a compressed-air drainage clearing tool operating at up to 200psi), and Lithium-Ion Battery Test Cells (Swagelok-type electrode cells for battery R&D and EV pouch cell development).

The company serves a diversified enterprise and research customer base including The AA (bespoke motorcycle tyre valve extensions), Taylor Woodrow (site-specific Roto-Lite colour and hazard marking), P&O Ferries (onboard Kinetic Ram maintenance), Warwick University/WMG International (battery test cell research), Portsmouth Hospitals NHS Trust (sexual health campaigns), Fairfax Cryobank (sperm-shaped marketing merchandise), and A+T Instruments. MPM operates a dual business model: contract bespoke plastic component manufacturing and tool design on a quote-based, direct-engagement basis, plus direct sales of proprietary branded products through e-commerce platforms (Amazon UK, eBay) and a global distributor network spanning Europe, North America, Oceania, and Africa.

MPM remains entirely founder-owned with no institutional investment, no funding rounds, and no disclosed revenue. The company employs approximately five staff (including founder Giovanni Nieddu, finance lead Julie Nieddu, and skilled factory engineers at the Portsmouth facility), does not publish pricing (quote-based for custom work), and runs a sales-led GTM with direct phone and email engagement, MailChimp newsletters, and case-study-driven website content marketing. Two registered trademarks — Roto-Lite and Sperm Keyrings — provide the principal intangible asset base.
