About SAMHWA
Forty-five years of engineering trust.
From a single workshop in 1979 to equipment operating in more than fifty countries — the SAMHWA story is one of patient, precise engineering.
Company Overview
Built on a simple conviction: process equipment should simply work.
SAMHWA Mixing Technology Co., Ltd. was established in 1979 to solve a persistent problem: critical mixing and thermal equipment that promised on the datasheet and disappointed in the plant. Our founders — process engineers by training — set out to build equipment whose performance could be predicted, proven and guaranteed.
Four decades later, that conviction still governs everything we make. Every static mixer is CFD-modelled before a plate is cut. Every exchanger is thermally rated and mechanically verified. Every ejector is performance-tested against HEI standards before it ships.
Today, from our headquarters in Staines-Upon-Thames, England, we serve refineries, chemical plants, food producers, power stations and shipyards across more than fifty countries — many of them customers for over thirty years.

Mission · Vision · Values
What we believe. How we build.
Our Mission
To engineer process equipment of uncompromising precision and reliability — protecting our customers' people, product and plant on every continent.
Our Vision
To be the manufacturer the world's process industries specify by name — the benchmark for mixing and thermal engineering excellence.
Our Craft
Design, fabrication, testing and documentation under one roof, one quality system and one accountable team since 1979.
Precision
Tolerances, predictions and promises — all engineered to be kept.
Reliability
Equipment designed for decades of service, not warranty periods.
Innovation
CFD, new materials and better geometries, applied where they earn their place.
Partnership
We succeed when your plant runs — on every continent, in every time zone.
Innovation & Manufacturing Excellence
A laboratory's curiosity. A workshop's discipline.
Our engineering office and fabrication shop share one building and one conversation — so every innovation is one that can actually be welded, tested and shipped.
- ✓In-house CFD cluster for multi-phase mixing simulation
- ✓HTRI thermal rating and FEA pressure verification
- ✓Coded welding to ASME IX and EN ISO 15614
- ✓Full NDE capability: RT, UT, PT, MT and PMI
- ✓HEI performance test rigs for vacuum systems
- ✓EN 10204 3.1/3.2 material traceability on every unit
Leadership
Engineers first. Managers second.
Every member of our leadership team began at the drawing board or on the shop floor — and it shows in how the company is run.
