On the production line at Ningbo Guangway Machinery, General Manager Mr. Chen picked up a newly machined valve component. "Our products start with forging," he said. Each component begins with a carefully forged blank, ensuring a dense internal structure and reliable strength.
Subsequently, the blanks enter the CNC machining stage, where they are processed into precisely sized finished products using precision CNC machine tools. Mr. Chen emphasized, "Precision is the lifeline of valves; there is no room for error here."
The most critical step is the surface treatment. All parts are first phosphated, forming a protective film on the metal surface to enhance adhesion; then, electrostatic powder coating is applied, and after high-temperature curing, a strong, corrosion-resistant coating is formed.
"Phosphating as a base coat, followed by powder coating – this 'double protection' process significantly extends the lifespan of the valves in harsh environments," Mr. Chen concluded. This mature process is precisely why Guangway Machinery's valve components are highly trusted in demanding industrial sectors.
