Thanks to the know-how acquired over 20 years, HEBEI SANSO MACHINERY CO.,LTD is able to design, build and install ERW welded tube mill for the production of tubes in the range from 8mm up to 508 mm diameter, manufacturing them according to production speeds and thicknesses and specification upon customer specification.

Besides complete welded tube mill , SANSO provides individual parts for the replacement or integration into existing welded tube mill : uncoilers, pinch and leveling machine, automatic shearing and end welding machine, horizontal spiral accumulators, and fully automatic packing machine.

The Sanso Machinery Difference

As the premier welded tube mill manufacturer, SANSO MACHINERY prides itself on standing behind the equipment it produces. Consequently, SANSO MACHINERY must be much more than a design company that simply assembles equipment. To the contrary, we are a manufacturer in every sense of the word. Short of purchased parts such as bearings, air/hydraulic cylinders,motor&reducer and electrical components, SANSO MACHINERY manufactures approximately 90% of all the parts, assemblies, and machines that leave its door. From stand to machining, we do it all. 

For this transformation of raw materials to cutting-edge first class equipment to occur, we have strategically invested in equipment that gives us the ability to produce quality parts and yet flexible enough to meet the requirements of our design team and preferences of our customers. Our almost 9500square meter state-of-the-art facility is comprised of 29 CNC vertical machining centers ,6CNC horizontal machining centers,4 large- size floor type boring machine,2 CNC milling machine.21 CNC gear hobbing machines and 3 CNC gear milling machines. 4 Laser cutting machines etc.

As the manufacturing environment has trended toward customization from standardization, it has been a focal point for SANSO machinery to be able to handle any challenge thrown its way.

Regardless of what is being made, today it’s a common practice to job out or outsource the manufacturing of products to other companies in China. Consequently, one might say that the production of our own parts does not align with industry norms. However,SANSO machinery feels that it gains a distinct advantage over our competition because of our in-house production capabilities. Producing parts in-house results in shorter lead times, which in turn allows us to service our customers more quickly than anyone else in the industry.

SANSO machinery is also able to maintain tighter control of quality, which has led to less manufacturing errors and higher levels of accuracy and repeatability. With our advanced manufacturing capabilities, we are also confident that our production capabilities can match our designs. In addition, it allows design improvements to be put in place instantaneously. Our manufacturing and design experience, along with advanced 3D modeling and drafting software, allows us to analyze functionality of each part and make any improvements as needed. Rather than wasting time communicating these changes to a sub-contractor, our upgrades happen in the time it takes our drafting department to deliver new prints to the shop floor. As good as our equipment and capabilities are, our greatest asset is our people.

Our model of manufacturing may be unconventional, but we feel that it is the best way to create the most value for our customers. From mind to metal, we oversee every step of the manufacturing process. In addition, we fulfill the cold commissioning of some equipment before leaving our facility. This assures the fastest and least costly installations in the industry. When you purchase SANSO machinery’s welded tube mill, you are guaranteed to receive a product that has been made with great pride every step of the way.

The Sanso Machinery Difference
