ダイワエクセル List of Products and Services

When requesting plating processing, do you have any of the following concerns? - The film thickness does not match the specifications indicated in the drawings... - Your requests are difficult and get declined... Daiwa Excel specializes in "zinc plating/zinc-nickel alloy plating processing" and has resolved many customer issues to date. The film thickness of plating processing becomes more challenging to stabilize in quality as the shape of the workpiece becomes complex. However, our company uses "dedicated jigs" tailored to the product shape for most of the jigs used in plating processing, allowing us to maintain stable film thickness and quality during plating. Since the plating jigs contain a lot of know-how, enabling in-house development and maintenance helps prevent the leakage of technical information. Additionally, we manufacture process equipment tailored to customer needs, such as secondary inspection, marking, and assembly. 【System capable of in-house design and production of inspection and processing equipment】 - Automatic marking processing machine - Inner tube plating inspection machine (luminance judgment) - Automatic surface inspection machine for plating (image judgment) *For more details, please refer to the PDF document or feel free to contact us.

"Electrolytic tin-zinc alloy plating" is used in automotive and aircraft parts due to its excellent corrosion resistance and high rust prevention capability, compared to conventional zinc plating. Single-layer zinc plating faces the issue of rapid wear of the coating, but tin-zinc plating has a smaller potential difference with iron, resulting in a slower progression of corrosion and achieving corrosion resistance. If you are concerned about corrosion resistance and rust prevention, please feel free to consult us. 【Features】 ■ Excellent corrosion resistance and high rust prevention capability ■ Used in automotive and aircraft parts ■ Tin-zinc plating has a smaller potential difference with iron ■ Slower progression of corrosion, achieving corrosion resistance *For more details, please refer to the PDF document or feel free to contact us.

This document provides detailed information on the characteristics of electroplated zinc-nickel alloy coatings and internal surface treatments. We may be able to solve issues for products that were previously thought to be impossible to plate on the inside or for which plating was deemed unattainable due to the characteristics of their shapes. If you are struggling with extending the lifespan of your products or improving their corrosion resistance, please feel free to consult us! 【Contents】 ■ Basic knowledge of electroplated zinc-nickel alloy coatings ■ Points to consider for electroplated zinc-nickel alloy coatings ■ Corrosion resistance mechanisms ■ Internal plating treatments ■ Corrosion resistance of zinc-nickel alloy coatings ■ Why was internal plating on bag structures and thin diameters difficult? ■ Scope of internal plating ■ Case study 1 for problem-solving ■ Case study 2 for problem-solving *For more details, please refer to the PDF document or feel free to contact us.

In our company, to meet our customers' quality requirements, we have "X-ray fluorescence measuring instruments" and "salt spray test machines" at each factory. We measure the electroplated products produced daily to ensure quality. In liquid analysis, we use "atomic absorption spectrophotometers" to measure metals that cannot be analyzed through neutralization titration. Since analysis can be conducted in-house, we can implement stable management based on planned measurements, and we can respond quickly in case of any abnormalities. 【Quality Control System】 ■ Analysis Room ■ Atomic Absorption Spectrophotometer ■ X-ray Fluorescence Measuring Instrument ■ Metal Microscope ■ Salt Spray Test Machine ■ Digital Microscope VHX 7000 *For more details, please refer to the PDF materials or feel free to contact us.

Our company specializes in "zinc plating/zinc-nickel alloy plating" for "complex-shaped products." Using our special technology, we have made it possible to apply plating even to the inner surfaces of bag structures with small diameters, which was previously considered impossible. We will create dedicated plating jigs tailored to the product shape, so if you are having trouble with plating processing, please consult us first. 【Features of Zinc Plating】 ■ Electroplating a "zinc" coating (5-13μm) on the surface of iron materials to provide rust resistance ■ Protection of the base material (iron) through "sacrificial corrosion protection" ■ Capable of accommodating a minimum inner diameter of 6φ ■ Capable of plating the inner and outer surfaces of long pipes up to 1300mm ■ Plating of inner and outer surfaces for products with multiple bends *For more details, please refer to the PDF document or feel free to contact us.

Daiwa Excel Co., Ltd. is a company that specializes in plating processing. It has become possible to apply plating to inner surfaces of bag structures and thin diameters, which were previously considered impossible. We can also accommodate plating inside bolts and complex-shaped pipes. While there are limitations to the types of plating we can provide, we have achieved this by creating custom plating jigs tailored to the shapes and utilizing special techniques. 【Available Plating】 ○ Zinc Plating ○ Zinc-Nickel Gold Plating For more details, please contact us or download the catalog.
