We will introduce frequently asked questions about spinning (herasuguri) and drawing processing. Molds are generally required, depending on the shape. It is also possible to use wooden molds according to the quantity. Additionally, we will manufacture dimensions according to the customer's wishes, but if high precision dimensions are required, we may need to consult with you. In the absence of specific instructions, the dimensional accuracy will be to JIS standards. On our website, we also answer frequently asked questions such as, "Can you handle square-shaped drawing?" and "Can we use molds from other drawing companies?" If you have any questions or requests, please feel free to contact us. 【Frequently Asked Questions】 ■ Is a mold necessary? ■ What is the dimensional accuracy? ■ Is it possible to manufacture in small lots? *For more details, please refer to the PDF materials or feel free to contact us.

A major feature of our technology is that we can perform "stamping processing and assembly." While many stamping manufacturers specialize in individual stamped products, we are capable of producing high-difficulty welded assemblies through in-house integrated processes. "Processing is possible even with stamping. However, by assembling through welding, we can shorten the construction period and reduce costs!" It is this "welding processing technology" that allows us to prepare various options and provide the best VE/VA proposals to everyone. 【Processing Example】 ■Product Name: Aluminum Pressure Vessel ■Material: A5052 ■Plate Thickness: 5.0t *For more details, please refer to the PDF document or feel free to contact us.

Drawn products are mainly processed from "discs" and "cylinders." In particular, drawing processing from cylinders requires cylindrical products with a nice roundness and good dimensional accuracy. Our company has the technology to consistently manufacture such cylindrical products in-house. Having the capability to consistently produce high-precision cutting technology, cylindrical processing technology, and welding processing contributes to the high precision of the drawn products we manufacture and the high precision of the assembled products. 【Processing Example】 ■Product Name: Body ■Material: SUS304 ■Plate Thickness: 1.2t *For more details, please refer to the PDF document or feel free to contact us.

Our strength lies not only in the combined processing of "welding" and "drawing," but also in the fusion of the techniques of deep drawing and machine spinning. We compensate for the aspects of "repeatability" and "force," which are difficult to achieve by hand, with spinning technology, while integrating deep drawing techniques for delicate parts and applications that are challenging for machines. This allows us to create high-difficulty products that cannot be realized by either method alone. In the case of manufacturing the nozzle part of the LE-8 rocket engine, we performed bulge forming using a large NC spinning machine. Additionally, for flange expansion processing, we utilized deep drawing techniques to achieve delicate shaping that cannot be done with an NC spinning machine. By effectively collaborating the techniques of deep drawing, spinning, and other related technologies, we strive to achieve the ideal "form." This is the essence of "Yorozu Shibori" technology. *For more details, please refer to the PDF materials or feel free to contact us.

Our company has introduced spinning machines early on to meet our customers' needs. In small-diameter spinning processing, our technicians faithfully playback the machining data they have taught, accommodating large lot sizes of 1,000 pieces or more. The differences in hardness due to variations in material lots and changes in plastic state are controlled by the operator's skills, injecting the know-how of the spinning process into the machines. That is our company's "spinning processing." 【Processing Examples】 ■ Small-diameter spinning processing ■ Material: Permalloy (Fe-Ni alloy) ■ Plate thickness: 0.8t *For more details, please refer to the PDF document or feel free to contact us.

• Processing Contract

We would like to introduce a case study of spinning processing that we conducted. We performed spinning processing on a 12.0t SS400 plate to create a hat shape through cold processing. If hot processing is carried out, it is also possible to process thicker plates. In another case where we spun a 16.0t A6061P-O into a dome shape, we performed cutting using turning. Our company is equipped with one of the largest NC spinning machines in the country and boasts NC spinning machines capable of processing at the highest level of plate thickness. Please feel free to contact us for inquiries. 【Processing Case】 ■Material: SS400 ■Plate Thickness: 12.0t ■Size: φ1100 *For more details, please refer to the PDF document or feel free to contact us.

This is an introduction to a processing example where large drawn products and canning processed items are assembled by welding, and then further shaped using a large draw-forming lathe, with shape corrections made. First, the top part, which is the center, is processed by draw forming using a wooden mold. The drawn product is then assembled with fan-shaped can products using TIG welding. The welded product is further shaped through draw forming. While carefully correcting areas of poor precision in the canning processed items and any distortions caused by welding heat, the shaping is done meticulously, and the functional surface (outer surface) is polished to completion. Through corrections made by draw forming, the precision of the functional surface (outer surface) is achieved at 0.2 (RMS value) against the theoretical value. 【Processing Example】 ■Part Name: DISH ■Material: A1050P ■Thickness: 6.0t *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of large deep drawing processing that our company has conducted. The size is φ1000mm, and the plate thickness is t2.5. The edges of the drawn product are processed with R bending using a roller jig. Additionally, the R shape is carefully and quickly processed while checking with an R gauge. Furthermore, we also have examples of cost reduction achieved through our can manufacturing and drawing technologies. 【Processing Example】 ■Part Name: Tray ■Material: SUS304CP ■Plate Thickness: t2.5 ■Size: φ1000mm *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a representative example of small to medium-sized deep drawing processing that our company has conducted. The material is pure copper, and the thickness is t1.5. A single sheet is drawn to a depth of 300mm. The skill of controlling the thickness while working, feeling the changes in the metal such as work hardening that occur due to plastic deformation, through the "spoon" that one operates, is truly a craftsman's skill. 【Processing Example】 ■Part Name: Copper Container ■Material: Pure Copper ■Thickness: t1.5 *For more details, please refer to the PDF document or feel free to contact us.

"Spinning processing" is a method of plastic processing where a flat or tubular material (blank/work) is pressed against a rotating mold (mandrel) using processing rollers or paddles to shape it. As a forming method for shell-shaped products made of metal, it is widely used in the manufacturing of parts and products such as household containers, decorative crafts, lighting fixtures, communication devices (such as parabolic antennas), boilers, tanks, nozzles, engine parts, and tire wheels. This processing method has recently gained attention as a highly skilled manufacturing technique performed by experienced workers, and it is well known that items like the nose cone of the H2 rocket have been produced using this manual method (paddle spinning). [Features] - Capable of forming products with complex shapes compared to press forming - Easy preparation for processing since only one mold is required - Compact equipment due to low processing force *For more details, please refer to the PDF document or feel free to contact us.
