Innovative Processing Examples on Drawing

In the case of USB-TYPE C SHELL

Since the year 2015, there have been some USB-type-C coming onto the market; our company’s expertise, deep drawing is used on some of those USB-type-C.
In the past, the general processing pattern for USB point shell was a combination of the conventional bending processing, welding or bending processing, and calking.
However, by changing the method to the deep drawing, it became possible to produce products with no seams which the conventional method was not able to do.
The proposal of VA and VE applying deep drawing greatly contributed to improve the strength and reliability of the connector.

Gifu Seiki Kogyo can perform both prototypes and mass productions of shells for USB 3.1-Type C plug by deep drawing.
We are one of the few presswork manufacturers in the world who have succeeded in mass production by deep drawing utilizing its own die design skill.
“Seamless integral structure” becomes possible when produced by deep drawing, and it is the biggest characteristic.

About USB-TYPE C SHELL

usb_typeC
USB Type-C is a new standard for connectors which was established in USB’s next generation standard “USB 3.1”.

The USB Type-C connector has no up or down orientation. You don't need to worry about plugging it in upside down as it will function both ways. Therefore, the problem which was often observed with the conventional type USB Type-A connector; that is “Insertion is impossible because of the vertically opposite direction.” does not occur with Type-C connector.

Why is Gifu Seiki’s USB 3.1 Type-C shell chosen?

(1) External beauty of the shell surface

Deep drawing often results in visible wrinkles and cuts/scratches on the surface of the product. However we can make our products without any wrinkles. We are ranked as No. 1 Japanese manufacturer for no wrincle products.

(2) Flexible on designing of punching positions and sizes.

When produced by progressive type, punching in the side requires very difficult skills.
We will be happy to consult with you regarding the punching position, shape, size in order to meet your requests.

As compared with other processing methods, the deep drawing has the above listed characteristics. By making the product seamless, you can get various merits such as improvement of appearance and strength, and so on. If you want to manufacture high-quality plug shells, we recommend you to adopt deep drawing.
