Group
Your Single Industrial Partner — From the First Pour of Molten Metal to the Finished Part.
POSTEC Group is a Thai industrial partner for die casting, metal forming, automotive, and electronics factories, made up of three companies. We began as production consultants and now supply what we once specified.
Hydrosyn
Our lubricant brand: over 80 products list of engine, gear, hydraulic and industrial products carrying API, DIN, AGMA, NSF and machine-maker approvals.
POSTEC Corporation
Production consultants turned suppliers. Manages Hydrosyn's domestic fleet, construction and workshop channels alongside our own improvement solutions, furnace construction and locally made replacement parts.
Monster Tech

Origin
We sell only what we once specified
POSTEC began on the factory floor solving cost, waste, and safety problems. We own no factory of our own, so we choose the right answer from the whole market.

Cycle
Close the Material Loop . All Within One Cycle.
A foundry consumes lubricants, generates dross, and needs new metal. We built our group to handle every step of that cycle.
- Lubricants and process chemicals enter the production line
- Dross and metal waste are collected under licence
- Smelting recovers the metal, so less waste leaves the loop
