What are the reasons for failing the client inspection? Aligning perspectives on pass/fail.
Even good products are rejected by customers. This is a method to eliminate judgment differences by aligning the standard samples and inspection conditions.
Here, it's a pass; at the client, it's a fail. The reason for the differing judgments is that the criteria are based solely on words. ────────────── ■Cause of Occurrence The pass/fail judgment of appearance changes depending on the viewing distance, angle, and lighting. Writing "no scratches" without setting conditions will not yield consistent judgments. ■Truth When light is shone from an angle, unevenness that is not visible from the front becomes apparent. Just a 30-centimeter difference in inspection distance can change the size of defects that can be detected. Without a standard sample, the criteria shift every time the person in charge changes. ■Improvement Measures Set numerical values for inspection distance, illumination, and viewing angle, and share physical standard samples. Keeping both pass and fail products as samples stabilizes the judgment. Eiwa Kogei is responding to the establishment of inspection conditions based on standard samples.
basic information
Inspection conditions: Set inspection distance, illuminance, and observation angle with numerical values / Samples: Limit samples, acceptable product samples, non-acceptable product samples / Inspection items: Appearance, film thickness, color difference, adhesion / Records: Storage of inspection results records

Delivery Time
Applications/Examples of results
Establishment of appearance inspection standards, creation of limit samples, and resolution of discrepancies with customers. It includes the setting of inspection conditions, including inspection distance and illumination, as well as management of samples for acceptable and unacceptable products.

We are not just a "subcontracted painting factory." Established in 1958, our company has a foundation of painting technology and also specializes in chemical treatment, stripping, and cleaning, functioning as the "external surface treatment department" in your organizational chart. Based on our philosophy of "preparation is eight-tenths of the work," we emphasize participation from the "upstream process" before the drawings are finalized. We conduct test painting on a wide range of metals and difficult materials, and we produce the entire process from assembly, packaging, to delivery, thereby reducing your management workload. Additionally, by being able to perform zinc phosphate treatment in-house, we achieve stable painting quality. Furthermore, our micro-heating stripping technology, which does not use chemicals, maintains the electrical state of the "jigs (hangers)" that influence painting quality. Our approach of "pre-treatment determines painting quality" ensures the stability of the paint film during mass production. Rather than simply "applying specified standards," we work backwards to achieve optimal painting specifications and prevent scratches during transportation, sparing no effort in thorough discussions from the outset. This diligent preparation is the shortest path to preventing rework and minimizing total costs. From the development stage, please utilize the expertise of our specialists as part of your production line.
