Polish a small section of mold with 15 micron blue diamond compound to be sure that you are getting all 600 grit sandpaper marks out. (If not, you will have to use a finer sandpaper, 900 grit andn proceed to blue diamond compound.) Lessen
It\'s called Polishing Technology and it aims to kick your polishing skills up a notch with classes for beginner, intermediate and expert mold polishers. As I walked the halls of Plastec West last week, I stopped by the booth of Gesswein and learned about its successful new intiative to train mold polishers.
Buffing Aluminum After a good brushing job, it\'s time to do a soft buff, but before you begin it\'s critical to take a good, long look at exactly how deep the brush marks are. They are probably only .0002 of an inch deep or less, so when you start with the buff, press
An Aluminum Mirror is produced to high optical quality using India ink and single-point diamond turning. Because of the relative softness of aluminum, heretofore, there has been no way to polish bare aluminum to an optical quality adequate for precise
These videos and step-by-step photo tutorials will introduce you to basic techniques for successful moldmaking. These tutorials are suitable for beginners. Whether you are interested in how to make a mold for reproducing a sculpted figure, an antique picture frame
Optical metal polishing of flat surfaces can yield finishes in the 10 to 20 Angstrom Ra range depending on the alloy and the quality of the alloy. Optically polished mirror surfaces on Aluminum typically range from 20 to 30 Angstroms

Investigations were conducted into the sodium zincate solution used for treating aluminum prior to its being plated. Measurements of the adhesion of the nickel plate to aluminum and its alloys were done to check the effect of modifications made to
How can I plate copper on Degrease. Soak clean. Thoroughly rinse. Dip in a 50 percent nitric acid solution. Depending on the aluminum alloy, sodium bifluoride, sulfuric acid or chromic acid may have to be used in conjunction with nitric
The Mold Polishing Experts With today\'s tight tolerances, quality mold polishing is critical to your injection mold\'s success. There has been an explosion in technology. In the injection molding industry we have gone from making buttons and combs to high tech

Transparent aluminum starts out as a pile of white aluminum oxynitride powder. That powder gets packed into a rubber mold in the rough shape of the desired part, and subjected to a procedure called isostatic pressing, in which the mold is compressed in a tank of hydraulic fluid to 15,000 psi, which mashes the AlON into a grainy
As 2020 comes to a close, I thought I\'d share what you have been reading most on the MoldMaking Technology site. It provides a little insight into the type of information and specifics topics you want to learn more about. Here are the Top 10 most

And, aluminum is continuing to emerge as an alternative for some tool time- and cost-savings for certain applications. particularly in how to polish, texture, and repair these materials. However, aluminum offers several advantages over steel
Electropolishing aluminum does not produce toxic fumes, require fume hoods, produce corrosion or require high temperatures. To control the bath, FWA takes the specific gravity and checks the aluminum metal content. see it as a big advantage over bright
South Bay Technology, Inc. has developed a series of equipment designed for this purpose and is described below. lapping plates, ranging from aluminum, cast iron, and glass. Below is an image showing the Model 920 with a typical setup for lapping.
The process is most effective on soft materials, such as aluminum and brass. It also can be used to deburr steel and iron, depending on burr size and how strongly the burr is attached to the part. It is particularly useful for cast parts, such as engine blocks, transmission housings, cylinder heads and intake manifolds, because it removes machining burrs and flash in one
