What is Polystyrene? Polystyrene (PS) is a widely used thermoplastic polymer derived from the styrene monomer. It is an amorphous, transparent, and relatively brittle material with excellent insulation properties and moldability. Structure and Properties of Polystyrene Molecular Structure It is a linear polymer composed of repeating styrene monomers, with a phenyl group attached to every other carbon atom in the backbone chain. This aromatic structure contributes to its transparency, rigidity, and thermal stability. Physical Properties Thermal Properties Types of Polystyrenes General-Purpose Polystyrene (GPPS) High-Impact Polystyrene (HIPS) Expandable Polystyrene (EPS) Extruded Polystyrene (XPS) Composite/Recycled Polystyrene Polar/Functional Polystyrene Copolymers Production of Polystyrene…

What Are Shock Cords? Shock cords are composed of an elastomeric core, typically made of rubber or rubberized composite materials. Their unique property is the ability to stretch and absorb shock loads, making them suitable for various applications requiring shock absorption or tensioning. Types of Shock Cords Benefits of Shock Cords Shock Absorption The primary benefit of shock cords is their ability to absorb and dissipate shock or impact forces. Their elastic nature allows them to stretch and contract, effectively cushioning the force and preventing sudden jerks or snapping. This property makes them ideal for securing loads, especially in situations…
What Is a Spur Gear? A spur gear is a cylindrical gear with straight teeth parallel to the axis. It is one of the simplest and most widely used types of gears for transmitting power between parallel shafts. Spur gears consist of a hub, a toothed ring gear, and a connecting structure between them. The key geometrical parameters include the number of teeth, module, pressure angle, and tooth profile. Types of Spur Gears Benefits of Spur Gear Applications of Spur Gear Power Transmission and Motion Transfer Spur gears are widely used for transmitting power and motion between parallel shafts in…
What is An Actuator? An actuator is a device that converts energy (electrical, hydraulic, pneumatic, etc.) into motion or mechanical force to control or move a system or mechanism. Types of Actuators How to Choose The Right Actuator? The selection of an appropriate actuator depends on various factors related to the application requirements: Applications of Actuator Electromagnetic Actuators Electromagnetic actuators, such as geared and direct drive motors, are widely used in robotics and automation due to their quick response, high controllability, and precision. They are suitable for applications requiring precise positioning, controlled acceleration/deceleration, and maintaining desired positions. Hydraulic Actuators Hydraulic…
What is An Overhead Crane? Overhead cranes are a type of crane where the hook-and-line mechanism runs along a horizontal beam that itself runs along two widely separated rails. How Does An Overhead Crane Work? The overhead crane operates by coordinating the motions of the bridge, trolley, and hoist to lift and position the load: Components of An Overhead Crane Overhead cranes typically consist of a bridge beam supported by end trucks that run on elevated runways. A trolley with a hoist mechanism moves along the bridge beam to lift and transport loads. The key components include: Types of Overhead…
What is A Bevel Gear? A bevel gear is a type of gear used to transmit rotational motion between intersecting shafts at an angle, typically 90 degrees. It consists of conical or tapered gear teeth that mesh with another one to transfer power and motion. Manufacturing of A Bevel Gear The manufacturing process of bevel gears typically involves the following main steps: Pre-cutting Methods Hardening Techniques Common hardening methods include case hardening (carburizing) and induction hardening to achieve a hard surface and tough core. Hard Finishing Methods Different Types of Bevel Gears Straight Bevel Gears Spiral Bevel Gears Hypoid Bevel…
What is A pressure Tank? A pressure tank is a vessel designed to hold pressurized fluids (liquids or gases). It typically consists of a hollow body or liner that defines the storage space, surrounded by a composite fiber material for reinforcement. The Mechanism of Pressure Tank Maintaining the desired pressure level inside the tank is crucial for proper functioning: Types of Pressure Tanks Benefits of Using A Pressure Tank Applications of Pressure Tank Energy Storage and Supply Pressure tanks are widely used for storing compressed gases or liquids under high pressure, serving as an energy storage and supply system. They…
