Special features of thin sheet metal fins
There are features that can be realized
by folding and forming thin sheet metal.
01. Wide range of fin types
We can provide the fin shape and size
that best meet requirements.
02. Total support from prototyping to mass production
Those in a large number can be
provided in coil form.
03. Micro shapes with a height of 1 mm or less
Press processing technology of
thin sheet metal cultivated by us
Shapes of thin sheet metal fins
We have prepared a wide range of fin shapes to meet customer needs.
We can also propose manufacturing methods suitable for customer request.
※Only available as prototypes
Fin shape application samples
Without limiting to the above, we can offer a wide variety of fins as many as the number
of customer applications, such as fins of punched metal or other special materials.

Estimated manufacturable range
Table serving as a guide for the manufacturable range of corrugated fins, offset fins, and waving fins
Since the manufacturable range varies depending on sheet thickness, pitch and height, please refer to the following.
The manufacturable range of folding fins is described on this page.
|0.05～0.5||1～25||H/5+T or more||FP×2||10～600||free choice||nearly the same as sheet thickness|
|0.1～0.3||1～15||1.4 or more||FP×2||10～300||free choice||nearly the same as sheet thickness||1 or more||2T～FP/2|
|0.1～0.4||1～30||H/5+T or more||FP×2||10～600||free choice||nearly the same as sheet thickness||Please refer to the following.|
|About symbols and units||：: T = sheet thickness, H = height, FP = fin pitch, YP = 1 rib pitch, W = material width,
L = length, R = bending inner radius, OW = offset width, OP = offset pitch,
WR = wave radius, WP = wave pitch Units are all in millimeters.
|About L size||: If using regular sized material, L size with a developed length of 450 mm will be the full length that can be processed.|
|About YP size||: If the upper and lower FPs are different, FP upper + FP lower will make YP.|
|About WR/WP size||: WR/WP size will be determined by balance.|
How to use varies from person to person.

Processed using press dies and special processing equipment
Wide width fins and high aspect fins
There are customers having demands for fins with wide width 、
or high aspect ratio (pitch/height).
We have strived to fulfill these using our technology. Now it is possible
to offer such products with a shorter delivery date and competitive price.
