Blind Rivet Guide: Types, Sizes, Uses, Installation and Removal

A blind rivet may be small, but choosing one correctly involves more than matching a rivet to the nearest drill bit. The diameter, grip range, hole size, body material, mandrel material, head style and installation tool all influence the finished joint. A rivet that looks perfectly acceptable before installation can still spin, loosen, pull through the sheet or form incorrectly on the blind side if one of these factors is overlooked. Blind rivets are widely used in sheet-metal fabrication, electrical ......

Stepper Motor Applications Explained: 5 Motion Modes and Use Cases

Stepper motors are widely used in CNC machines, 3D printers, medical devices, packaging equipment, laboratory instruments, and countless other motion control systems. While these applications span different industries, the reason a stepper motor is selected is usually the same: its motion characteristics match the requirements of the application. Search for stepper motor uses online and most articles classify them by industry. However, a syringe pump and an optical focus stage belong to completely dif......

Servo Motor Torque Explained: Understanding Torque Ratings for Motor Selection

Every servo motor selection decision starts with one question: does the motor produce enough torque for the job? Get this wrong, and the system either stalls under load, overshoots during positioning, or overheats within hours of commissioning. This guide covers the torque specifications you will encounter on servo motor datasheets, walks through the calculation process and explains how to verify your selection using torque-speed curves. Whether you are sizing a new axis for a pick-and-place machine o......

Servo Motor Control System: A Complete Guide to Components, Working Principles, and Selection

Every axis of motion in a modern factory — from a CNC spindle interpolating a contour to a robotic arm placing a chip on a PCB — depends on a servo motor control system doing its job in the background. The system coordinates a motor, a drive, a feedback device, and a controller in a continuous closed loop, correcting position errors thousands of times per second. This guide breaks down how a servo motor control system works, what each component does, how the three control modes differ in practice, and......

Pressure Sensors Explained: Working Principles, Types, and Applications

Introduction Pressure sensors are widely used in industrial automation, process control, hydraulic and pneumatic systems, HVAC, and medical equipment to measure the pressure of gases or liquids and convert it into electrical signals for PLCs, controllers, and monitoring systems. In our previous article, "What Is a Pressure Sensor? Definition & Applications" we introduced the definition and industrial applications of pressure sensors in detail. In this guide, we will explain the main types of pressure ......

Threaded Inserts Guide: Types, Uses, Installation Tips, and Mechatronic Applications

1. What Are Threaded Inserts? Threaded inserts are mechanical fastening components used to create strong, reusable internal threads in a base material. Instead of relying only on threads cut directly into aluminum, plastic, wood, cast metal, or a 3D printed part, a threaded insert is installed into a prepared hole. The insert then provides a durable female thread for a screw, socket head cap screw, or hex bolt. In practical terms, threaded inserts help materials hold screws more reliably, especially w......
