Steel investment casting is a one of the oldest metal-forming techniques, dating back to the times of the ancient Egyptians and the ancient Harappans in India. Original investment casting techniques were performed using beeswax and clay, but today’s investment casting manufacturers use more sophisticated techniques to create smooth, intricate forms in less time. One of the most significant advances in investment casting is the creation of rapid drying chambers. These chambers reduce the time it takes to complete the layering process, which used to take several days. Because the new drying chambers allow the investment casting manufacturer to create layered…

What Affects AC & DC Gear Motor Longevity
An AC or DC gear motor is designed to have a long life. The length of that life depends on which type you choose from a gear motor catalog, or custom build, along with its intended purpose. However, the way you stress and maintain a DC or AC gear motor can affect its longevity for better or worse. The following factors affect the durability, performance and efficiency of gear motors: Environment of use. Inappropriate environmental temperatures and high humidity can shorten the life of an AC or DC gear motor. While in use, the ideal temperature range for a gear…
Choosing a Progressive Die or Line Die Stamping Vendor for Automotive Stamping Applications
Progressive die stamping and line die stamping for automotive stamping applications are services manufacturers commonly seek because they can help save time, reduce costs and provide consistent results. When you choose a metal stamping vendor, it’s important to consider more than just the bottom line. As you shop for custom stamping or contract stamping services, look into the following: Design help. A good vendor offers design assistance to ensure an economical stamping process – and to ensure the finished part performs well. Production options. Progressive die stamping may not be the only, the best or most cost-effective, option available. Alternatives…
BLDC Motor Controllers: Features & Types
When you look through a DC motor catalog, you’ll notice that no two BLDC motor controllers are alike. Because they’re often used for applications that require variable or adjustable speeds, BLDC controllers must be flexible enough to suit the application. Some controllers simply provide the electronic commutation to make the motor operate as well as the ability to reverse direction. More complex controllers may integrate a programmable microcontroller so that the user can program lots of motor functions. Some BLDC controllers are small enough to put inside the motor case. These “embedded” controllers make it easy to substitute a high…

Steel Investment Casting & the Modernization of the Lost Wax Process
Steel investment casting, also called lost-wax casting, uses techniques that date back over five millennia to make complicated metal objects like turbine blades, firearms, golf club heads and implants for hip replacements. Ancient Civilizations Archaeologists have uncovered evidence that ancient civilizations used investment casting to make jewelry, idols and ornaments using beeswax, clay and manually operated bellows. Such cultures – like those in the Egyptian, Aztec, Mayan, Harappan, Mesopotamian and Benin civilizations – often used gold, bronze and copper. In 1100 A.D., Theophilus Presbyter, a monk, created written accounts of the investment casting process he used. Italian artist Benevenuto Vellini…
Benefits of the Three-phase Brushless DC Motor Technique
Gaining popularity through various industries, the brushless DC motor is a type of synchronous motor. The permanent-magnet rotors within the BLDC motor use electronic sensors that detect the rotor’s position and a DC supply that powers an AC signal inverter. Instead of using a traditional commutator with brushes, the BLDC motor has stator windings that get electronically commutated. The lack of a traditional commutator gives the brushless DC motor several benefits over other types of motor drive architectures. These benefits include: Higher efficiency Less maintenance Ability to operate at higher speeds Smaller sizes No voltage drops across brushes (because there…
