◆2.0ｍｍ thick narrow groove processed with ｔ4.3ｍｍ ＳＰＨＣ material
Thanks to our unique processing technology, we can remove groove capillarities up to half the board thickness.
We can process with various equipment from 30ｔ one-shot press to 200ｔ transfer press.

Shearing
◆Parts accuracy
① Whole circumference shearing by one-shot molding （Shearing lenght：70% of the board thickness/surface roughness：Ra3.2）.
② Partial shearing by transfer molding （Shearing lenght：80% of the board thickness/surface roughness：Ra1.6）.
Thanks to the improvement of our molding process technology, we can shear with standard press machine.

Wire-forming
SWM-B（Φ4.5～Φ10） /Piano wire（Φ4.5～Φ8.0）
Product lenght：up to 1200ｍｍ
We can straighten coil material though roller correction equipment and process using programable controllers.
We also have no loss of material when creating coil material.

Multi-forming
SPCC（MAXｔ1.5） /material width：MAX50ｍｍ
Thanks to facilities equiped with both press and bending machinery, and servo-motors controlled arms, we are able to continously process complex bent products.

Chemical polishing
◆Installation capacity：Board thickness （T=0.9～10）/product diameter （Φ8～Φ135）
◆Part accuracy：Parallelism （0.02MIN）/board thickness（±0.02MIN）/surface roughness（Ra0.2MIN）
Because we can polish both sides at the same time, it is easy to respect the board thickness/parallelism and suppress any heat treatment strain.

Sub-assembly
We can realise riveting, spot welding and all sort of assembly.
Presentation of the Meiko Spring's worldwide superior technology. Thanks to its technology Meiko Spring can do what other can not.
