Main Contract Manufacturing Models

CASE 1: Contract Machining of Individual Parts

We machine the materials provided by our customers at Tanabe. In addition to machining, we also offer laser cutting and press forming services.
The shape of the supplied materials does not matter. We can cut standard-length bars, tubes, and large sheets to the required part dimensions and machine them as needed.

CASE 2: Contract Machining of Large Machinery Parts

At Tanabe, we provide machining and finishing services for large machinery parts that our customers have already welded and assembled.
We can machine products weighing just under 20 metric tons on our gantry-type machining center and just under 10 metric tons on our vertical lathe. Please contact us for details, as size restrictions apply.

CASE 3: Material Procurement and Contract Manufacturing of Parts

We manufacture and machine parts based on your designs, including material procurement.
By having our company handle everything, including material procurement, we can reduce the burden on our customers’ production management.

CASE 4: Turnkey Contracting for Procurement, Manufacturing, Welding, and Finishing

We provide turnkey manufacturing services for parts based on your designs, covering everything from material procurement and small-part fabrication to welding and finishing.
By entrusting us with multiple processes, we help reduce your administrative burden and shorten delivery times. We can also handle post-machining blast finishing and painting on a contract basis.
