Contract Coating Service
Gas phase technologies
We offer a variety of methods for both vacuum and atmospheric pressure.
Organic and inorganic (metals, compounds, oxides, nitrides) films can be formed with a thickness of 1 nm to 10 µm with high quality and precision.
Low temperature (room temperature) DLC coating & Low temperature (room temperature) ALD coating. Leave it to us to provide surface treatment coatings such as decorative coatings, surface modification, quality improvement, and long life using electrochromism.
High frequency plasma generates hydrogen ions, which are attracted to the substrate by DC high voltage pulses and react with the raw material gas (CxHy) on the substrate surface, enabling high quality DLC deposition with good adhesion at low temperatures.
Using electrochromism, it is possible to deposit decorative films with variable luminescence color (i.e., change the color to the user’s favorite color) not only on materials and components but also on consumer products.
low-temperature DLC and low-temperature ALD
Coating films generated by high-frequency plasma and DC high-voltage pulses are currently being rapidly adopted in the hard disk industry, precision mold industry, copy machine and automobile industries, and are expected to expand into the field of coating optical components and resin materials in the future.
High frequency excited DLC low temperature deposition
Effect of low-temperature DLC coating
Electrode/electrode protection material
Improvement of high coating and high conductivity of collecting electrode for Li battery. Thin and soft films can be applied on thin, flexible and porous materials without impairing the function of the product. The electrical conductivity is greatly improved due to the high conductivity characteristic of graphite.
Mold release film
Improving high mold release and adhesion. Especially for adhesive resins, it has excellent mold release effect and prevents reattachment.
Effective for better molding, increasing productivity, and reducing maintenance work.
Abrasion resistant coating
Durability is improved by DLC deposition on automotive parts such as engines and suspensions, metal parts, and medical supplies.
Low friction coating
Film formation on films and plastic products to provide friction reduction effects and structural reinforcement.
Low temperature ALD deposition
Effect of low-temperature ALD coating
Gas barrier film for resin
・Alcoholic beverage encapsulation: Lighter weight and longer life for beer and wine
・Pharmaceutical and cosmetic packaging: Cost reduction of containers, possibility of acid-alkali packaging
for medical use
・Resin catheters and syringes: Anti-coagulant membrane inhibits coagulation of proteins (blood, etc.) due to microstructure of resin.
・Dental implants: cell adhesion membrane increases durability and improves cell retention.
・Ag mirror surface in endoscope: Corrosion inhibitor film protects against sulfur components
Protective film for electrolyte
of all-solid-state battery
・Sulfide system: inhibits H2S generation by forming a protective film on the powder.
・Oxide system: Improvement of electrolyte crystallinity during sintering.
・Addition of functions to positive and negative electrodes.
for magnetic materials
・Motor cores: Anti-oxidation
・Inductor cores: increase in magnetic permeability
decorative film and changeable color film deposition
Effects of decorative and color changeable film coatings
Color changeable film
Electrochromic technology is used to create devices that can change the color of small fashion items such as nail tips and bags, small household items such as bottles and bags, and small interior items.
Metallic luster film
・This technology enables the formation of highly adhesive films with vivid colors and gradations on three-dimensional objects and resin surfaces.
FAQ - Frequently Asked Questions -
What kind of films and film types can be formed?
We are capable of depositing not only general metal and alloy films, but also various oxide and nitride films such as reflective, light-shielding, and transparent electrodes.
We also specialize in “carbon films” such as DLC (Diamond-Like Carbon) and graphite, and can provide highly functional films such as high hardness, low friction coefficient, high mold release, and abrasion resistance to meet customer needs.
What kind of workpieces (materials) can be applied on?
Mainly the following base materials can be used.
“Resin, film, and other materials that are sensitive to high temperatures can be coated at low temperatures without losing the performance of the material.
“It is possible to form a film on metal, glass, etc. with uniformity and high adhesiveness.
“It is possible to form a thin, uniform film on various particle diameters and shapes, such as powders and ultra-small parts.
What are the main applications for film formation?
We are capable of general film formation, but are also good at the following cutting-edge fields.
“Also able to provide highly functional films for new materials and new energy fields such as all-individual batteries, lithium-ion batteries, and fuel cells.
“We can provide biocompatible films and gas barriers for medical devices such as medical resin catheters, vials, and implants.
What thickness of film is possible?
“It is possible to form dense, homogeneous and uniform ultra-thin films even at 1nm (nano).
If it is a powder, uniform coating to φ100nm is also possible.
As for the film thickness, we can propose a coating method that meets your needs.
