The photo chemical etching process is used to produce very precise parts that would otherwise be difficult or
impossible to manufacture using conventional fabrication method.
Advantages of The Photo Chemical Etching
Low Cost and Design Flexibility
Compared to hard tooled parts, the photo chemical etching tooling is more efficient and far less expensive than typical hard tooling. In addition, design and drawing changes are expeditiously and inexpensively accomplished.
Short Delivery Time
The chemical photo etching can typically be produced in one or two days.
No Burrs and no stresses
In the photo chemical machining operation, the part configuration is achieved without any surface burrs and stresses.

Process of Inspection
① Inspection before feeding of materials
Thickness, evenness and the surface state are inspected before materials are fed. In case of abnormality feeding of materials is immediately suspended and its report is made to the superior office.
② Midway inspection
Products on each line are inspected with the naked eye and stereoscope, and in case of etching the calibrations are inspected with pin gauge and stereoscope.
③ Sampling inspection
Products stored in the inspection room are subject to sampling inspection in accordance with JIS 9015 and only those pass the inspection qualify for the total number inspection.
④ The total number inspection
In principal the inspection is conducted with the naked eye and pin gauge, but inspection with measuring instruments (magnifier, stereoscope) is conducted on demand.
You can choose from the following part packaging options, regardless of the quantity.
Etched Dimensional Tolerance
The dimensional tolerance depends on plate thickness. Generally it is 10%～15% of plate thickness
External and internal angles are rounded when etching
External angle(Ro) ≧ ｔ × 40％ ｔ＝Thickness
Internal angle(Ri) ≧ ｔ × 80％
|Thickness(T)||Minimum D Size||Actual Minimum D Size||Actual Minimum W Size||D, W Tolerance|
|Subject to Testing||Subject to Testing||≒ 0.5||Subject to Testing|
|125㎛||≒ 0.7t||≒ 0.8t|
“D”: 0.8 X T
Special tolerances such as ± 0.01 μm other than general tolerance differ according to the characteristics of the product.
|Line||Size||Lead Time(min)||Productive Capacity(Sheet)|
|Cleaning||SUS 0.1t x 400 x 500||8||1,500||3,700|
