Yumoto CNC Machining Case Study: A5052 Precision Components with High Quality Black Anodizing Finish

Author: Rumiko (Rumi) Inoue (Sales and Marketing)  

Project Overview

Yumoto Vietnam recently completed machining aluminum A5052 precision components for one of our customers in Vietnam. The order included more than 20 drawings, each drawing with quantity 10~20 units.

Customer Requirements and Cost-Reduction Strategy

For this project, our customer wanted us to cut costs where possible so our sales team proposed using two types of aluminum A5052 grades – Japanese and Chinese grades. For the larger base plates, we used the Japanese grade and maintained as-received surface finish, which means keeping the original surface of the material. This approach reduced machining time and cost while also preventing plate warping. For smaller parts and simpler parts, we suggested using Chinese grades material, which offers a significantly lower cost per kilogram.

Production Management and Lead Time Achievement

Thanks to our production manager’s careful time management and our engineers machining the products efficiently, we were able to complete production one week before the customer’s requested lead time.

Examples of our Machined Components

Here are some pictures and videos of the products. Many of the products required black anodizing finish:

Example Product 1:
Aluminum A5052 – Japanese grade
As-received surface finish with black anodizing
Dimension: 10T x 75 x 321 (mm)

Example Product 2:
Aluminum A5052 – Chinese grade
Black anodizing
Dimension: 15T x 30 x 230 (mm)

Example Product 3:
Aluminum A5052 – Chinese grade
Black anodizing
Dimension: 20T x 41 x 273 (mm)


Example Product 4:
Aluminum A5052 – Japanese grade
As-received surface finish with black anodizing
Dimension: T8 x 60 x 90 (mm)


Example Product 5:
Aluminum A5052 – Chinese grade
No anodizing finish (as-machined surface finish) 
Dimension: T22 x 35 x 45 (mm)


Example Product 6:
Aluminum A5052 – Japanese grade
As-received + machined surface finish with black anodizing
Dimension: T18 x 380 x 640 (mm)
