Surface Coating

Iwata's surface coating technology

  • Mulitple coating layers precisely realizes designer's image.
    • Formation of a coating layer by using multiple coating guns and finely atomized paint
    • Application of Maximum 4 coating layers is possible; flexibly meeting customer's requirements
  • Wide range of painting methods
    • two component- paint, high temperature cured paint, UV cured paint, electro deposition coating
  • Cutting edge cure-oven to ensure paint's reliability: adhesion and hardness property.
  • Flexible control of substrate's surface conditions
  • Functional coating such as lubricant and conductive coatings
1. Multiple coating layers

Dilemma of traditional surface coating

2. Wide range of coating methods available

IWATA has wide selections of painting methods from spray coating with two component-paint, high temperature-cured paint, UV cured paint to electrodeposition coating.

Our coating lines are equipped with the cutting edge cure ovens to maximize the reliability of the high temperature cured paint.

Advantage of high temperature cure paint:High adhesion and hardness properties and high productivity

  • High pencil hardness (more than 3 H) and high adhesion property for metal substrate.
  • Two-component paint takes about 24 hours to 1 week to be completely cured and thus timing of the reliability testing is delayed.
    High temperature cure paint is completely cured in a high temperature onven and can be put on a reliability testing just after products come out of the painting line. ===> production effeciency is greatly increased.
3. Cutting edge cure-oven to increase the paint's reliability

Specially designed cure oven maximizes the reliability of both two componet paint and high temperature cure paint.
By instaling a cure oven on each coating booth, reliability of each coating layer is assured.

4. Flexible control of the substrate's surface conitions

By controling the substrate's surface conditions depending on a customer's requirements, adhesion property of paint is increased and the appearance that a designer requires can also be precisely realized.

Selections of substrate processing

  • Sandblasting
    Enhance the adhesion property of the paint and realize the designer's image.
  • Chemical polishing
    Make the substrate shiny and enhance the metalic tone.
  • Electro polishing
    Make the substrate very shiny, good for the preporcessing for electrodeposition coating.
  • Buffing
    Make the mirror suface by mechanical polishing, realizing the high grade appearance.
  • Spin pattern processing
    Varieties of spin patterns can be made with NC machine tool, generating 3 dimensional apperance.
  • Hair line procerssing
    Depth and width of hairline patterns can be selected
5. Functional surface coating such as the application of lubricant paint on the friction area is also available.

Integrated manufacturing from part making by press working and functional surface coating is possible.

APPLICATION01.

Surface coating of smart phone's metal cover.

Make spine pattern on the sufface with NC machine tool and cover the suface with transparent colour coating, realizing 3-dimensional surface appearance..

Coating structure

3 coating layers

※Orange peel and picture framing minimized by the use of multiple coating guns and evenly applied fine atomized paint.

※Substrate is processed with special NC machine tool.

High gloss surface coating

APPLICATION02.

Surface coating of digital camera covers
with shiny metalic paint.

By applying silver metallic paint at thickness of less than 1μm, sandblasted surface becomes as shiny as polished surface.
High quality shiny metallic tone is achievable at very low cost.

Mirror Silver Coating

AG NANO coating

AG NANO coating

One of the apeals of smart phones and MP3 players is the mirror finish of its surface.
IWATA has established mirror silver coating method, which is one of the most difficult and challenging coating techniques, and applied it to massproduction of camera covers in a more stable and economical way than traditional mirror silver coating.

Traditional mirror silver coating requires advanced techniques of a skilled coating technician.
IWATA has achieved stable massproduction of mirror silver coating by using 4-booth painting line for the first time in a world.

Disposal of water for rinsing, which is one of the biggest headache in traditional silver mirror coating, is also saved by 4 booth painting line that can handle base coating, mirror silver coating, colour paint coating, and top transparent coating in succession.
More economical and ecological surface coating is possible.

IWATA has satisfied the requirements of leading designers by providing advanced surface treatment and coating to the camera covers of the world presiegious brand.
Mirror silver coating is one of IWATA's achievements in surface coating as a result of pursuit of the following:

  • More advanced surface coating techniques.
  • World class painting facilities and accessaries.
Features of AG NANO coating
  1. With sophisticated IWATA's surface coating techniques, a most beautiful mirror surface is available.
  2. More economical and reliable production than hand working by an experienced technician is possible.
  3. By using 4-booth massproduction painting line, massproduction of mirror silver coating is possible.
Applicable field
  1. Mirror finish for smartphones and MP3 players.
  2. Mirror finish for PC and tablet computers.
  3. Mirror finish for digital cameras.
  4. Mirror finish for cases of cosmetic products.
  5. Fishing tools
