Pneumatic actuated valve stem technology currently makes up over 80 percent of the market. It is the most widely used technology in the medical, technical and closures markets.There are several reasons why pneumatic systems are so widely applied. The technology uses a medium that is readily available in molding facilities—compressed air—to move the valve system. [...]
To counter common accuracy and setup concerns in large machines, we must look at some of the necessary design characteristics of a large mold machining center. […]
Dealing with the sheer size and weight of a large mold can be a big challenge. This often leads to excessive labor, […]
Following is a list of seven daily habits to include—the most mentioned, or in some cases, the most vehemently defended. Here they are in order of frequency: […]
Ultrasonic units with super fast, very short strokes, provide virtual unrestricted finger tip control. By comparison, regular reciprocating tools—such as air-driven or electric flexible shaft-operated die profilers—are more restrictive in movement and less flexible to handle. Nevertheless, die profilers and/or various other filing machines are great for medium to large mold details and when used [...]
We need to stay objective and remind ourselves that ultrasonic polishing is not for everyone. Frequently, ultrasonic systems are perceived to take care of all polishing problems. This is not so. Ultrasonic polishing is not a cure-all for every mold and die shop that does in-house polishing. […]
By comparison to conventional die profilers, as well as air-powered lapping machines that may have a stroke length of up to ¼ inch, the reciprocating action of an ultrasonic unit ranges only from .00004 to .00012 inches. […]
In many cases, an NC polishing machine will not completely replace a polisher. For example, if you have thin, deep ribs in your workpiece, you may not be able to fashion a stone or other media into the holder to give you satisfactory results. […]
Listed below are 10 questions that will demonstrate the current level of data utilization that exists in your company that is readily available for a repair technician, supervisor, manager or engineer to use on a daily basis. […]
To provide the high-performance results demanded in today’s moldmaking, many indexable-insert ballnose endmills use PVD-coated, precision-ground, micrograin- carbide inserts. Experience shows that such inserts perform best with sharp edges, […]
