Mirror polishing for molds sample<\/span><\/h2>\n

Sample of button configuration.<\/span><\/p>\n

The mobile phone button shapes have undergone electric discharge processing.\nOnce these processing lines have been completely removed, the list of further processes includes application of the grindstone, paper treatment, shine production and the mirror completion processes.\nEven with a small area, unless the surface is completely flat it cannot be described as a \u201cmirror surface\u201d.\nHashimoto Industry excels at this kind of precision work.<\/p><\/div><\/div>

Sample of reflector configuration.<\/span><\/p>\n

Polishing repeatedly until the processing lines are removed without destroying the shape and carrying out the finishing processes for the perfect shine by hand for each and every process requires unrivaled concentration and determination.\nMoreover, because the sample is considerably heavy it is not possible to change the direction to make the work easier.\nThe finished mold reflects light like a jewel.\n(Post-polishing on the left and pre-polishing on the right.)<\/p><\/div><\/div>

Sample of audio panel polishing.<\/span><\/p>\n

This kind of mold, with several angular and protruding buttons, faces a certain problem at the grindstone stage.\nThe problem is that grooves arise in certain locations, similar to the \u201ccrossings\u201d of a road.\nWhen trying to finish a mirror, it is unacceptable to have even the slightest distortion in the surface.\nGrindstone work, which ultimately decides the final dimensions of the mold, is an unimaginably delicate process.<\/p><\/div><\/div>

Sample of keyboard mold polishing.<\/span><\/p>\n

Molds for keyboards need to be of the \u201csuperfine\u201d quality ranking because top musicians will notice during performances when there are distortions, even if these are at a level that is impossible to detect by the naked eye.\nIdentifying these tiny distortions is so tough that there are very few testing technicians capable of making these judgments.\nEven in Japan, there are very few companies capable of producing \u201csuperfine\u201d quality.\nOne of these is Hashimoto Industry.\n<\/p><\/div><\/div>
