A new ideal to moldmaking
A few months ago, I suggested that MoldMaking Technology sponsor an art exhibit comprised of molds and tooling. Moldmakers could present their work in pictures or as sculptures on a show floor. […]
every Mold maker should develop global strategy
The main challenge in dealing with any strategy for business growth is that it is interdependent with opportunities and being prepared to capitalize on them when they occur. Developing a global strategy will help a small business increase its opportunities; however, not many small businesses have time to use this concept to their advantage. They [...]
Automation is coming to first-rate mold company
first-rate mold company plans to come out of the recent recession with numerous advantages for their customers in the injection mold and precision machining market segment. The advantages offered are a result of the company’s long-term commitment to automation technologies. […]
Molding Knowledge will help a test
Word of first-rate mold company’s abilities traveled quickly, leading to an order for an automotive grille piece that put their injection molding knowledge to the test. […]
Please select proper electrode material
Selecting the proper electrode material to produce a fine surface finish is vital to the success of the application. It is important to understand which material provides the potential for achieving an acceptable finish without the need for excessive handwork or polishing. By realizing the role that the microstructure of the material plays in producing [...]
Electrode material is important on Quality EDM Finish
A common belief in the moldmaking industry is that a lower quality electrode material can be used to produce superior surface finishes if a high quality EDM machine is used. While the technologies of the newer generation EDM sinkers have allowed the EDMer to become more proficient in the application, […]
How to mill graphite electrode
With graphite, the magic words are high speed. High speed machining centers with 30,000- to 60,000-rpm spindles are capable of accelerated feeds that serve to reduce cycle times and improve surface finish, as well as edge quality. […]
Automation comes into EDM drills
Automation for EDM drills comes in two main forms: (1) simple mechanical toolchangers and (2) comprehensive robotic systems. Both perform essentially the same function. However, where a toolchanger usually just moves the tool chuck in and out of the machining head (albeit automatically), a robot can also transport electrodes, guides and workpieces in and out [...]
Copper impregnated graphite helps EDM in moldmaking
Common work metals, such as tool steels, are easy to EDM with traditional graphite electrodes. Others are not. Because of their unique characteristics, questions continue to arise about effectively EDMing materials like Beryllium Copper, Titanium and Tungsten Carbide. Even though graph-ite electrodes do an admirable job of EDMing these exotic metals, there is a more [...]
What Is Copper Impregnated Graphite?
There have been many theories written on how copper graphite is created, many of which are completely untrue. […]
