Insufficient degreasing leads to poor adhesion. An explanation of the importance of the often-overlooked degreasing process.
In the painting of OA equipment enclosures, the adhesion of the paint film is emphasized to ensure the product's appearance quality and durability. Particularly in the case of aluminum die-cast materials, poor adhesion of the paint can easily occur due to the adhesion of release agents or processing oils, which can lead to peeling or deterioration of appearance. Even trace amounts of oil, which are difficult to detect visually, can cause issues such as peeling of the paint film, blisters during the curing process, and pinholes. When the degreasing process is shortened to improve productivity, it is not uncommon for the costs of re-coating or handling complaints to increase as a result. As the first step in addressing adhesion issues, standardizing the degreasing process and reviewing management conditions are essential. 【Usage Scenarios】 - Painting of aluminum die-cast OA equipment enclosures - Products requiring appearance quality and durability - Cases facing challenges in managing the degreasing process 【Benefits of Implementation】 - Reduced risk of peeling due to improved paint film adhesion - Suppression of painting defects such as blisters and pinholes - Reduction in costs for re-coating and handling complaints - Enhanced appearance quality and reliability of the product

basic information
**Features** - Identify and explain the causes of poor adhesion in aluminum die-cast painting. - Describe the mechanisms behind paint film peeling, blistering, and pinhole formation due to insufficient degreasing. - Explain the necessity of standardizing the degreasing process and reviewing management conditions. **Our Strengths** From pre-treatment to painting, stripping, and delivery, we provide one-stop service in Hirano Ward, Osaka. Founded in 1958, Eiwa Kogei has been dedicated to metal surface treatment for 65 years. Our painting company handles "pre-treatment, stripping, and delivery." We consistently manage the surface treatment of metal products from zinc phosphate treatment (in-house) to baking paint, inspection, packaging, and delivery. Including paint stripping and cleaning handled by our group company, PPC Corporation, we can consolidate processes that were previously spread across multiple vendors. If you are facing issues such as deadlines being "when it's done," difficulties in managing separate vendors for pre-treatment and painting, slow responses to painting defects, or unresponsive cost review consultations, we can provide a rough estimate on the same day if you bring in the actual item or drawings. We deliver within the Hirano, Yao, and Higashi-Osaka areas using our own 2-ton trucks. We can recoat 5,000 items within three days even for painting defects. We have the capability to produce 300,000 items per month in 100 varieties and 30 colors.

Company information
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.
