introduction

BENDINGASSEMBLING

We have a various CNC Benders and can performbending work for wide range of tubes. Bending
accuracy is guaranteed by specialized 3D measuring
device.

Assemble the tubes, according to the customer's
required speciﬁcations. At the beginning stage, askilled worker manually manufactures it and then use
Jig for mass production, thus suppressing variationsin quality. In addition, after tube assembly aremeasured with a specialized coordinate measuringmachine to ensure dimensional accuracy.

▲ CNC Bender▲ Assembling▲Coordinated Measuring device(Non Contacting Type)▲JIG Assembling▲ Coordinated Measuring
Machine (Contacting Type)WELDING
The main welding methods are TIG welding and MAG welding. We oﬀer a wide range of welding for various shapes
and small diameter tubes up to large diameter tubes, including manual welding by skilled workers, as well as
automatic welding equipment and robot welding equipment. After welding, Quality control does inspection of thewelded tubes, by through visual inspection of the exterior, internal welding inspection using an endoscope, and ahydrogen leak inspection and above all, these are to increase the quality control of the products.

We have established a system for integrated production of tube processing
for construction machinery products. Suitousha's strength is that it has aseries of functions of prototyping, test & evaluation and production, andthese are integrated. A factory in Japan has established itself as a motherfactory, and sharing its technology and skills with overseas factories.

PICKLING & PAINTING
There are various chemical process, such as tube surface cleaning and rust removal and anti-rust coating. The anti-rust
coating can be processed in two types, zinc phosphate coating and zirconium coating. There are two types of automatic
painting equipment that can consistently perform for primary and ﬁnish painting, including a liquid painting line and a
powder painting line. In addition, a manual painting booth is also available, enabling for single-item. In order to meet theincreasing requirements for painting quality in recent years, we have developed visual inspection, ﬁlm thickness measuring
inspection, contamination inspections. The principal of painting is "The clean environment can produce clean product.
