Project Overview

Zhejiang Nuodun is an established fire extinguisher manufacturer specializing in the production of dry powder fire extinguishers and water-based fire extinguishers.

With increasing market demand and rising labor costs, the customer required an automation upgrade solution to improve production efficiency, reduce manual operations, and enhance manufacturing consistency.

Based on the customer's existing production experience and upgrade requirements, Guangzhou Zhongwen Machinery Equipment Co., Ltd. provided a customized fire extinguisher production line automation solution, integrating automated welding, inspection, filling, packaging, and palletizing processes.

The project helped the customer upgrade from traditional manufacturing methods to a more efficient and automated production system.
