A Closer Look at Electrical Tests In one of our previous posts, we discussed the importance of product testing in manufacturing. In this article, we’ll focus on the most common types of electrical tests. Hipot Testing Although many of the tests required by safety certifications like UL or [...]
The Basics of Stepper Motor Control Due to their durability, reliability, efficiency and availability in standardized sizes and mounting options, stepper motors are widely used in industrial automation, robotics, and new niche consumer products like desktop 3D printers. In this article, we’ll talk about the basics of how [...]
Moving Down the Line: Electromagnetic Linear Actuators In a recent post, we discussed the main categories of electric motors and how they operate. While those electric motors fulfill an important need any time you have to convert electricity into rotational motion, sometimes rotation is not the type of [...]
Sealing the Deal: A Primer on Rubber Injection Molding Injection molding isn’t just for thermoplastics. The same process, with a few minor tweaks, can also be applied to synthetic rubbers. Having largely displaced natural rubber for almost all uses except automobile tires, modern elastomers (short for “elastic polymers”) [...]
A Rundown of Runners Before molten resin can fill the part cavity, it must first wind its way from the sprue (the inlet of the mold) to the gate(s). In between those two end points, the molten resin is distributed through channels, called the runner system. Think of [...]
How to Successfully Contract Out Cable Harness Assembly A lot of OEMs (particularly smaller ones) use cable assemblies in their products built in-house and usually do the assembly by hand with the help of tools like crimpers, strippers, and heat guns. Building these harnesses by hand is very [...]
Choosing the Right Motor Can Really Move Your Application Forward By converting electrical energy into motion, electrical motors literally keep our modern world turning. From compressors to ceiling fans, vacuum pumps to vacuum cleaners and dialysis machines to drones, motors are everywhere. They are so significant that entire books [...]
Are You as Pumped about Pumps as We Are? Out of the three normal states of matter—solid, liquid, and gas—pumps can move the last two and pressurize the last one. Pumps not only force fluids to flow, but can also create a vacuum by compressing gas to a [...]
Overlooked Thermal Considerations for PCBAs Although we immediately think of electronics when printed circuit board assemblies (PCBAs) are mentioned, good PCBA design is in fact a multidisciplinary endeavor spanning electrical, mechanical, and even chemical engineering. However, one area where technology companies can run into trouble with PCBA designs, [...]
The Importance of Tool Material Choice In injection molding, there are two critical “material” choices that need to be made: which plastic material to make the product out of, and which tool material to use when building the part’s mold. Each choice has many options, but to add [...]
