Some examples of customization

Semi-customized (modified)

Development is based on the specifications of products that have a track record of development (with molds).
The closer the customer's required specifications and the product specifications in Unifive are, the shorter the development time can be expected.
In terms of cost, development costs can be reduced compared to full custom.

Full custom (product development)

Even product specifications with no development track record (no mold) can be commercialized according to customer requirements. We develop custom-made parts, including detailed requirements, designs and safety standards.
