永和工芸 Product Lineup

The main causes of painting defects known as "drips" are excessive paint application, improper viscosity, and variations in gun distance. Eiwa Kogei manages paint viscosity within the appropriate range and standardizes discharge volume, spray distance, and angle to prevent excessive paint adhesion. By visualizing conditions that eliminate variations among operators, we achieve stable quality. If you are experiencing painting defects, please feel free to consult us. **Main Causes of Drips:** - Paint viscosity is too high or too low - Discharge volume from the spray gun is too high - The distance between the gun and the product is too close - Variations in painting angle - Applying too much paint at once **Eiwa Kogei's Measures and Initiatives:** - Regular measurement and proper management of paint viscosity - Standardization of discharge volume, gun distance, and angle - Visualization of working conditions and improvement of procedural documentation - Reduction of variations among operators

"PPC" refers to a service that means Peeling, Paint, and Cleaning. We offer proposals for pretreatment and paint stripping. In pretreatment, we perform zinc phosphate treatment in barrels, accommodating mass production of iron products in palm-sized units, ranging from 1,000 to 10,000 pieces. We contribute to addressing challenges such as searching for subcontractors due to the lack of in-house facilities. For stripping, we carry out chemical treatment with ultrasound and stripping solution, heating treatment with micro-heaters, and polishing treatment with blast equipment. This removes paint accumulated on in-house jigs, leading to cost reduction. Please feel free to contact us when you need our services. 【Processing Methods】 ■ Zinc phosphate treatment in barrels ■ Chemical treatment with ultrasound and stripping solution ■ Heating treatment with micro-heaters ■ Polishing treatment with blast equipment *For more details, please download the PDF or feel free to contact us.

In the design of office furniture, aesthetics and durability are important factors. In particular, high-quality coating is essential to meet diverse design needs. Powder coating allows for thick film application in a single coat, achieving a high level of design expression. Additionally, it has low VOC emissions and is an environmentally friendly coating method. 【Usage Scenarios】 - Office chairs - Desks - Cabinets - Partitions 【Benefits of Implementation】 - Improved design quality - High durability - Reduced environmental impact - Cost savings

When performing powder coating, there are several constraints in the manufacturing of the powder coating materials, which has led to the following drawbacks until now: ● Designated colors cannot be produced unless a demand of at least 150 kg of powder coating is anticipated. (Therefore, small lot painting is not possible.) ● Additionally, the production of designated colors requires a period of more than one month. (Thus, delivery times measured in days are not feasible.) With this situation, it has been difficult to adopt powder coating despite its advantages. We are advancing initiatives as part of our "new approach to powder coating," including: ● Utilizing a stock of over 2,000 colors based on the color card system from powder coating manufacturers. ● Collaborating with paint manufacturers capable of small-scale production of powder coatings, enabling designated color powder coating to be realized within one week, even for small lots. We have established a system that leverages the strengths of powder coating, such as the ability to achieve a thick film (approximately 50μ to 100μ) in one coat, minimal VOC emissions (almost zero during processing), and faster painting speed compared to solvent-based coatings.

Our painting factory has three systems. We want to respond to our customers' requests in a detailed manner, and this system has been developed over approximately 50 years with that intention. (1) A system for painting single items and small lots (2) A system for mass production painting (3) A system for test painting Currently, we have three main types of painting equipment available, allowing us to paint from one item or one unit up to 10,000 items or 10,000 units. However, there are limitations regarding "size," "shape," and "weight." Please take a look at our company website first. We will propose the optimal specifications for "baked painting" according to your requests, including the painting specifications you designate, quality, performance, and budget (cost). There are various possibilities, such as cases where costs can be reduced by controlling material expenses, and cases where upgrading the material grade can shorten processes and achieve rationalization. Please feel free to consult with us.

You can choose from spray painting, anionic electrodeposition coating, and cationic electrodeposition coating. Each method has its own advantages and disadvantages, so we will select the painting method according to the product. It is possible to maintain the characteristics of the material while offering a variety of colors, making it suitable as an alternative to plating and for products that require aesthetic appeal. Various expressions can be achieved through combinations, so please consult us first.

Whether it is powder coating, solvent-based baked coating, or air-drying coating, the adhesion performance of the paint film and its corrosion resistance greatly depend on the pre-treatment methods that create a suitable condition for painting. In other words, simply removing oil and dirt does not create an ideal condition for painting. Pre-treatment refers to preparing the surface to be suitable for painting. One of the methods that provides excellent corrosion resistance and adhesion among pre-treatment processes is zinc phosphate coating. We regularly measure the concentration of the treatment solution to ensure stable quality.

Since our establishment, Eiwa Kogei has introduced various equipment and devices as needed in response to our customers' requests. Equipment for stripping paint is one of them. In response to requests for repainting defective products or changing colors, we can strip the paint from products that have already been painted and repaint them. We perform stripping treatment in several patterns depending on the material and shape. First, please let us know the condition of the product you wish to strip. We will suggest the most suitable method.

When high quality and adhesion are required for the painting of aluminum (die-cast) and zinc die-cast products, we adopt "chromate treatment," which is a pre-treatment for painting aluminum (zinc). By applying "chromate treatment" to aluminum materials and zinc die-cast products, which are considered difficult for paint to adhere to, we can impart "high adhesion" and "high corrosion resistance." These non-ferrous metal materials often encounter adhesion issues during painting. It is necessary to align the required quality and painting specifications during the design phase of the painting process.

By applying zinc plating to the product, it can achieve high rust resistance and corrosion resistance. Furthermore, by applying chromate treatment to the zinc-plated surface, discoloration (whitening) of the zinc-plated surface can be suppressed and colored. This allows for a wide range of responses to the required corrosion resistance and aesthetic qualities when combined with painting.
