China's industrial era was just beginning. BAUTU's first batch of molten iron fowed into a sand mold for a DN50 grey-iron
valve body.
From the very first valve, one rule was carved into BAUTU's DNA: "Every single piece must withstand inspection.'

As customers demanded tighter tolerances, we installed our first generation of precision CNC equipment. Our process moved from "experience-based" to "standards-based" manufacturing.

This was the decade when most competitors chose to outsource castings, machining, and inspection. It looked flexible — but it meant losing control. We took the opposite path.

We expanded on-site, growing the plant to 20,000 square meters. We brought the foundry, machining shop, heat-treatment furnaces, pressure test rigs, and metrology lab all under a single roof. From molten metal to material certificate, every step now happened under our own watch.

With our integrated foundation set, we attempted something harder: to double our output without bringing in a single outsourced step.

Today, BAUTU's facility covers 50,000 square meters, with daily output exceeding 3,000 units, supported by a workforce of 300+ engineers and technicians who watch over every valve from casting to crate.

But what we are most proud of isn't the larger footprint — it's that three times the capacity still operates under one roof.
