Do you have any of these concerns?

Machining, forging, or casting costs
are too high

Complex shapes cannot be processed,
limiting design

You want weight reduction
but don't know the best method

You want part integration,
but welding has cost & accuracy issues

You want to reduce
extra costs from design changes

You want to increase
production speed for mass production

FAQ

FAQ

I want to consider press processing for existing parts. What should I prepare?

Please share drawings and information about your current process (material, cost, challenges). We will propose the optimal method.

Can you handle everything from die making to mass production?

Yes. We have a system that covers die design and manufacturing through prototyping and mass production. In some cases, mass production may not be feasible.

How long does prototyping take?

It depends on the shape and complexity of the product. Please consult us in advance if you have delivery requirements.

What are the benefits of consulting from the design stage?

Considering the manufacturing method from the early stage enables optimization of processability, cost, and quality. It also reduces design change costs after prototyping.
