Precision welding for molds
Precision welding for molds
Hashimoto Industry is able to handle a wide variety of welding from ultrafine padding to high-precision large-scale padding.
We are particularly expert at ultrafine padding (high-precision welding).
Women are rare in the welding industry, but our female staff have an excellent reputation for delicate welding.
Our experienced staff handle precision welding of large-scale padding, and our customers are extremely satisfied with the results.
A crane capable of handling up to 2 tons has been installed in the Welding Room.
Even if a mold weighs more than 2 tons, our experienced staff will handle the job by carrying out welding with the mold still on the truck.
We are sometimes asked to weld ultrafine padding at a level of hundredths of a millimeter.
We answer our customers’ requests as much as humanly possible by using precision laser welders.
We offer swift response to customers even on short notice.
We can also travel to a location of your choice, so please feel free to contact us with any questions.
Hashimoto Industry uses precision TIG welders and laser welders to handle everything from ultrafine padding (precision welding) to high-precision large-scale padding.

Redesign by welding half-padding
Redesign is the second most common reason for welding, after repair. Padding can be added exactly where it is needed. |


Customer opinions
- “Another company turned us down saying it was technically impossible, but Hashimoto Industry were able to do the welding for me as I waited!”
- “I’d imagined it would be like a factory but when I arrived it was a really nice and tidy place, which gave me peace of mind when I handed over my mold.”
- “There weren’t any electrodes and it wasn’t possible to do machine processing so I told them that it absolutely had to be done by hand. I was amazed by the accuracy of the padding.”
- “I had no idea that somewhere like this would do welding, and it completely changed the image I had of what welding was like!”
