Dara Etching developed an exclusive polishing technique keeping dimension, shape, sharp edgesand close tolerances. Our fine craftsmen can achieve any level of required finish. We have the facilities to polish molds of any size. We are one of the few companies in the India that specialize in Mold finishing on all types of molds. When a mold is nearing completion and a polisher is faced with several hours of polishing with only a few days to complete it, it’s time to look for immediate help with our man power we can usually assign several polishers to a single job to help complete it on time. It is not unusual for five of our polishers to be on the same job, thereby accomplishing a week’s work in a single day. The advantage to having experienced polishers on our staff offers a great deal of flexibility in helping a customer solve a delivery problem.
A-1 Grade #1 Diamond Buff
The finest diamond finish mostly used for finishing clear lenses, optics and critical cosmetic parts.
A-2 Grade #6 Diamond Buff
Close to an A-1 diamond but with less shine then A-1 diamond. Typically used on molds that produce cosmetic parts.
A-3 Grade #12 Diamond Buff
Close to an A-2 diamond but with less shine then A-2 diamond. Typically used on molds that produce cosmetic parts that don’t require a high finish.
B-1 600 Grit Paper
The highest finish before diamond process. Mostly used on highly cosmetic parts that are chrome plated or painted. (Close to A-3 diamond with a directional pattern)
B-2 400 Grit Paper
Close to a B-1 paper finish, but with a deeper directional pattern. Less shine then a 600-paper finish.
B-3 320 Grit Paper
Almost like a B-2 paper finish, but with a slightly deeper directional pattern.
B-4 240 Grit Paper
Deeper directional pattern then 320 paper finish typically used after stone for ease of finishing and appearance.
B-5 180 Grit Paper
Deeper directional pattern then 240 paper finish typically used after stone for ease of finishing and appearance.
Note: Please keep in mind that Paper grit finishes are not equivalent to their Stone counterparts. (Example: A 320 paper finish = approx. a 600 stone finish, 320 paper is twice as fine as 320 stone.)
C-1 600 Stone Finish Fine smooth finish mainly used on small detailed areas where paper finish is not feasible.
C-2 400 Stone Finish
Slightly rougher finish then 600 stone. Mainly used for removal of fine Machined finishes, where rougher stones may not be necessary to use.
C-3 320 Stone Finish
General purpose starting and finishing stone to remove machined finished.
C-4 220 Stone Finish
General purpose starting stone to remove rougher machined finishes. Deeper finish then 320-400 stone may be used for final finishing.
C-5 150 Stone Finish
Mostly used to remove very rough machined finishes.
Dry Blast Finishes
Dry Blast finishes may very due to material blasted, the amount of pressure used and at what distance Blast is applied. Keep in mind that blast material will break down and can’t be used indefinitely to achieve same results at given specification.
