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.

Case 1

Shape recovery through welding.

It is possible to carry out high-precision welding with little impact on the surrounding dimensions.
We are also able to keep sink marks to a minimum.

Case 2

Shape recovery for blade edges.

Our precision TIG welder allows us to carry out ultrafine padding.
This is an extremely valuable type of welding which only a small number of technicians are capable of performing, even at Hashimoto Industry.

Case 3

Welding of padding within a given frame.

This welding is carried out within a certain area that has been marked off.
We use precision laser welders to weld padding down to the hundredths of a millimeter.

Case 4

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.

Case 5

Edge padding in a circular configuration.

Mold edges and angles tend to get damaged easily.
In this photograph, we have carried out edge padding in a circle using 0.1 mm solvent.
After finishing, this technique allows edges to be restored.

Case 6

High-precision welding in a rib configuration.

Padding is welded on in order to reconfigure a rib section.
Re-cutting is required and as a result the technician needs to weld without bubbling, marking or cracking.

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!
