Plating process

There are many plated films. Introducing the lineup of plating processing that can be done with connection.

Please feel free to contact us for plating treatments that are not in the lineup.

Electroless nickel plating film is a method of forming a metal film on a metal or non-metal surface without using electricity. This is an effective treatment for products with strict dimensional intersections and products that require corrosion resistance and wear resistance.
Teflon electroless composite plating (electroless Teflon plating) is a plating film that combines the characteristics of Teflon such as mold release, water repellency, stain prevention, slipperiness, and slidability with the hardness and corrosion resistance of metals.
Nickel plating has good corrosion resistance and excellent mechanical strength.
For this reason, nickel plating is widely used for decorative plating and functional plating (heat resistance, wear resistance, solderability).
Hard chrome plating film (industrial chrome plating film) is a plating film that is extremely hard and has excellent wear resistance.
Recommended for various parts such as automobiles and motorcycles, and industrial products such as molding dies and rollers.
As a metal material, tin plating is harmless to the human body, so it is recommended for things that people can eat, such as tableware and thin steel plates for canning, and food containers.
In addition, because it has good solderability, it is a recommended plating film for electrical parts and electric wires.
The copper-plated film has excellent electrical conductivity, thermal conductivity, and malleability.
In addition, it is widely used in industrial applications such as printed wiring boards, precision electroforming, printing rolls, copper foil manufacturing, and carburizing prevention. For decorative purposes, it is used for base plating of nickel plating.
Gold plating is a plating film that has been used for Buddhist altars and accessories since ancient times for design purposes. It also has extremely high corrosion resistance and low contact resistance, and is also used in printed circuit boards, electronic components, and semiconductors.
Silver has been used in electrical and electronic components because it has the best electrical and thermal conductivity of any metal. In addition, because of its lubricity, it is used in bearings and metal bearings for power generation, ships, jet engines, trains, automobiles, etc.
The palladium-plated film is a silver-white film that is mainly used as a base for gold plating.
It is also used for decorative purposes as it can be used as a countermeasure against metal allergies (nickel allergies).
Palladium is a face-centered cubic noble metal with excellent thermal and chemical stability.
By alloying nickel, a plating film that is hard, has excellent malleability, and has excellent corrosion resistance with few defects such as pinholes can be obtained.
Surface treatment exclusively for aluminum materials.
It can be used for various purposes such as aluminum decoration, anti-corrosion and abrasion resistance.
Since it is possible to color various colors, it is possible to decorate the aluminum material with your favorite color.
Surface treatment exclusively for aluminum materials.
The film hardness is about Hv400, which is higher than stainless steel.
It is possible to add value to the hard alumite film by filling the fine pores of the hard anodized film with Teflon (PTFE: polytetrafluoroethylene).
A matte black film that is suitable for processing optical systems and semiconductor manufacturing equipment that have good craftsmanship and prevent diffused reflection. It can process materials that are difficult to anodize, and is recommended for motorcycle parts and camera parts.
Anti-rust coating "toughness" is, long-term corrosion resistance is characterized.
Not only does it last a long time, but it does not come off because an alloy layer is formed between the material and the plating film.
Since the silver mirror film does not use electricity, it is a plating film that can be used not only for metals but also for resin materials.
There are many color variations, and it is possible to express various colors with metallic luster.
The electrodeposition coating film is a coating film that enables even and highly uniform coating.
This coating film is recommended for processing products that require mass production because there is little color variation within the lot.
In buffing, craftsmen manually polish each item to remove small scratches.
It is also possible to polish difficult materials such as titanium and resin materials from general metals.
Lubrite (manganese phosphate, zinc phosphate) is mainly used as a base for painting, but it has various properties that have not been noticed until now, such as oil retention and insulation.
The advantage of galvanization is that zinc is electrochemically positive for the iron substrate, and even if the iron substrate is exposed due to film defects (scratches, cracks, pinholes, etc.), the zinc itself is sacrificed. It has the property of corroding and preventing the occurrence of red rust on iron.
