Processing glass surfaces through liquid chemicals…
The etching technique that Maruyama Frosting Co., Ltd.
has originated has been used for glass panels as well as what we have looked at so far.
Since our research on etching techniques began in 2003,
we have proposed numerous glass panels that meet the demands of the advanced information appliance industry.

Glass panel etching

Surface processing technology

Anti-Glare (AG) Processing Technique

Following the development of the FPD and organic EL techniques, we were able to expand our market coverage through the invention of the AG Processing Technique. This includes lightly frosting glass plates to give them an anti-glare effect. We are the first company in the world to venture into the business of AG processing of large-sized glass boards, and have been working to meet the needs of products such as glass panels used in top-class automobiles and outdoor LC advertisement signs.

Slimming

Chemicals can be used to thin glass without causing any micro-cracks during processing. A micron-level highly refined and even finish can be achieved through etching technology and expertise. Methods to reduce surface micro-cracks have also contributed to creating a strong and resistant finish.

Diffusing plate

Adding small bumps and dents to the glass surface allows for diffusing transmitted light. This technology is particularly necessary when light is applied by semiconductor lasers.
Products can also be tailored to provide the desired optical characteristics (diffusivity). Our technology provides significantly improved surface regularity compared with that with sandblasting, without any reduction in the substrate strength.

Imbricated processing

As with bottles and crockery, imbricated processing can also be performed on glass panels.
This decorative processing, which creates highly original texture, is a unique technology. It can also be used for chemically strengthened glass.

Partial processing technology

Cover Glass Processing Technique

Our Cover Glass Processing Technique was derived while we developed our organic EL expertise. It is a practice of partially extracting panel patterns through the use of a masking process. This makes it possible to extract a section of a smartphone panel. Because the Cover Glass Method processes panels by using liquid chemicals to melt them, it is better equipped to preserve durability than a cutting process.

Engraving Processing Technique

While establishing the production framework for our FPD Etching, we also focused on the potential of Organic Electro-Luminescent Liquid Crystal (LC). After several trials, we were able to use the FPD technique to produce thin baseboards, and integrated a masking process in order to carve grooves into the glass seals on the back of LC displays. In 2006, we completed our mass production line of organic EL glass seals.

Edge etching

Edge etching is a technology that involves using masking to only process the edge by melting it with chemicals. As the surface is melted with chemicals in edge processing, more strength is provided than with machining.

We have gotten rid of the former idea of processing lines, and have introduced our original industrial robots. By operating a robotic arm to immerse our products in each tank, it has become possible to automate and optimize our processing system. We have also installed a new pretreatment system that prevents pits, and an automatic titration machine that has the ability to cope with various acids to offer high-precision manufacturing.
