Are you facing any of these issues? ■ Difficulty in transferring pipe manufacturing skills ■ Wanting to update pipe manufacturing equipment but not knowing who to contact ■ Unable to conduct regular equipment diagnostics related to pipe manufacturing Since 1967, we have been a dedicated manufacturer of pipe production equipment for 67 years. For 30 of those years, we have also experienced in-house pipe production. Utilizing that know-how, we are currently offering support services for skill transfer in pipe manufacturing and measures against the aging of pipe manufacturing equipment. We will be exhibiting at MF TOKYO 2023, which will be held at Tokyo Big Sight, so if you are facing any of the above issues, please visit our booth. *Booth number: East 5-47

The "Laser Pipe Making Machine" is a pipe manufacturing machine for stainless steel that combines new laser technology with San-Etsu's pipe making technology. Since the heat-affected zone of the welding is small, it improves the issues of stainless steel processing cracks in subsequent processes. Additionally, the weld bead is small, so only external surface polishing is sufficient. 【Features】 ■ High speed and high precision ■ Improvement of processing crack issues ■ Freedom from concerns about internal bead cutting For more details, please refer to the catalog or feel free to contact us.

The "Pilger mill" rolls by inserting a mandrel into the inner diameter of the pipe and rotating it in a spiral while being subjected to a reciprocating motion by the rolls. It allows for high pressure, contributing to process improvement and yield enhancement. The cold Pilger mills used by major steel manufacturers in Japan adopt a large-scale mechanical cam system, while Sanmitsu offers a compact type with an electronic cam system. We can provide customized machines tailored to the applications and requirements of customers while keeping initial investment costs low. [Sanmitsu's Concept] - Equipment design that minimizes initial investment - High productivity achieved through unique design - High quality (good surface roughness, suppression of waviness) - Labor-saving through full automation and visualization - Joint development with customers - Confirmation of operability with demonstration machines *For more details, please refer to the PDF materials or feel free to contact us.

• Plastic processing machines (cutting and rolling)

The "Cold Pilger Mill" performs rolling by inserting a mandrel into the inner diameter of a pipe and rolling it back and forth with a reciprocating roll while rotating it in a spiral manner. It allows for high pressure and contributes to process improvement and yield enhancement. It also improves uneven wall thickness and surface roughness. Additionally, there are two-roll and three-roll configurations that can be selected based on efficiency and precision. This product is expected to find new applications in various fields, in addition to intermediate and finishing processes associated with the high-strength requirements of automotive parts. 【Features】 ■ Significantly reduces labor compared to conventional tube stretching methods ■ Allows for adjustment of various rolling conditions (rolling stroke, material tube feed pitch/angle, one-way rolling or reciprocating rolling) ■ Electronic cam system achieves compactness and energy efficiency, with numerical control capability ■ The TDN system realizes productivity that is 150% higher than conventional methods *From the [Download] section, we are currently providing materials that describe the differences between the cold pilger rolling method and the tube stretching method, along with the product catalog.
