Thin sheet metal fins

Fin parts made of a thin sheet metal as the name suggests
Processed using press dies and special processing equipment
Material, height, pitch etc. can be chosen
according to customer needs.

Special features of thin sheet metal fins

There are features that can be realized
by folding and forming thin sheet metal.

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.

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.

Estimated manufacturable range - Corrugated fins
Corrugated fins"
T H FP YP W L R
0.05~0.5 1~25 H/5+T or more FP×2 10~600 free choice nearly the same as sheet thickness

Estimated manufacturable range - Waving fins
Waving fins
T H FP YP W L R WR/WP
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.
