Integrated Production Process

Fully Quality Controlled In-house

Over the years, Nan Yun's screws and barrels have been fully satisfactory to all manufacturers of injection molding machinery and extruding machinery both domestically and overseas, and have established a long-term cooperative partnership.
In additional, NAN YUN continually invests in advanced processing equipment and gradually establishing the complete integrated process.
We also adopt the most modern production management to thoroughly control the quality of each step in the process.

In the screw part, from the design, material preparation, quenching and tempering, turning, CNC four-axis tooth profile processing, spray welding on the flights, interior-stress release, polishing, grinding, nitriding heat treatment, hard chrome plating, etc.
In the barrel part, from the design, material preparation, quenching and tempering, boring, interior grinding, turning, milling feeding hole, interior rifle groove, flange drilling, welding, finishing turning, nitriding heat treatment, etc., all these processes are completed consecutively in our company's production line and process arrangement.
The integrated process helps improve operational efficiency, shorten lead times, and we can control the manufacturing quality and reduce the cost to provide customers with high-quality, more competitive screw/barrel.

Precision Processing Equipment. Quality and Accuracy Guarantee

Improving the manufacturing technology of screw/barrel is one of the core strategies of Nan Yun.
Therefore, we continuously invest in advanced processing equipment, such as, deep-hole honing machine, vertical and horizontal CNC four-axis processing equipment, dual-bore barrel processing equipment, PTA spray welding processing equipment, alloy centrifugal processing equipment, rifling machine, wire cutting equipment, etc.
We believe ” It is necessary to have effective tools to do good works.”
Only perfect quality, our customers can make good machines and products, and then achieve a win-win situation and then establish long-term partners relationship.
