Kyowa Sangyou Co., Ltd.

We provide high-quality plating on a custom-made basis.

We provide custom-made plating with a focus on electroless nickel plating. Our HINOP® thick electroless nickel plating has three characteristics: ultra-thickness exceeding 1000 μm, high adhesive force, and a lack of pinholes. HINOP® has been adopted by many optical equipment manufacturers as electroless nickel plating for optical devices. We make use of our own original liquids, from the plating solution to the processing liquid. We have also devised equipment in order to enable thick plating on various materials. We develop our own original processing liquid and processing methods, so we can achieve highly difficult plating that cannot be done with plating solutions and processing liquids on the market.

[Company strength]
We make use of our original liquids from the plating solution to the processing liquid. The reason why we are particular about in-house development is that we hope to introduce our processing to customers with 100% confidence. We have also devised equipment in order to enable plating on various materials. We develop our own original processing liquid and processing methods, so we can achieve highly difficult plating that cannot be done with plating solutions and processing liquids on the market.

[Business description]
We provide a small amount of high-quality, custom-made plating one plate at a time, with a focus on electroless nickel plating. Our HINOP® thick electroless nickel plating has been adopted by many optical equipment manufacturers as electroless nickel plating for optical devices. We recently developed the M-MEMS® heat dissipation substrate for high-brightness LEDs. It is based on technology we developed with which adhesive plating can be applied onto various base materials. Both projects involved establishing an intensive corporate organization for supporting small lot orders, as well as orders for large amounts.

[Industry]
Metallic coating (such as electroless plating)

[Strength of products/technologies]
Our M-MEMS® is a heat dissipation substrate for high-brightness LEDs such as UV LEDs, which is realized with our original pre-processing technology. M-MEMS enables a vertical three-dimensional structure that could not be made with a conventional copper-clad substrate. M-MEMS plating is thick, so the dissipating capacity is excellent in itself. This is why it has been adopted as a substrate for UV LEDs, which require heat dissipation capacity. Our HINOP® thick electroless nickel plating is our representative technology. It has three major characteristics: ultra-thickness exceeding 1000 μm, high adhesive force, which can endure machining and subsequent molding, and no pinholes, which is an indispensable feature for dies. We now have a large number of customers who utilize HINOP® in the optical device field. We can also apply thick plating onto difficult-to-plate materials such as ultra-hard alloys, titanium, and ceramics. This is done while maintaining adhesive force that is strong enough to endure the processing. We have recently been receiving orders from customers in various fields by taking advantage of these characteristics.

[Representative's message]
The start of our new technology is often triggered by customer requests and consultations. Our target is to develop customer-oriented technology. Our company has 32 employees, 10 of whom are engineers in charge of technology development. Our goal is to develop second-to-none original technology. We are working hard to develop and pursue surface treatment in new fields in addition to our conventional thick plating for optical applications.

[Company structure for market development/overseas expansion]
We are now expanding our plating business through our overseas agencies in China, Taiwan, and Korea. Our engineers will also visit the customer with our sales staff if necessary, and provide explanations on the characteristics of our plating technology. 

[Market share/Ranking]
We have the top share in Japan in the market of thick plating for processing in the optical device field.
