HIPS, GPPS, EPS – understanding Polystyrene

Polystyrene (PS) is a thermoplastic designed for applications requiring excellent electrical and mechanical properties together with good process ability. Polystyrenes have well-balanced physical properties and are generally transparent, but available in various colors. Unfilled polystyrene has a sparkle appearance and is often referred to as crystal PS or general purpose polystyrene (GPPS). Because of the […]

Thermoforming

  Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or “film” when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that permits it to be […]

Extrusion: Learn About Grooved Feeding

In specific circumstances, Grooved Feed can increase output and reduce melt temperature. But these throats are not for every application. There are basically two types of single-screw extruders, distinguishable primarily by their feed-throat design. Most single-screw extruders have smooth-bore feed throats—basically a smooth pipe surrounding the rotating screw. Extruders with smooth-bore feed throats are affected […]

What is EN41b, Bimetallic and Tungsten-Carbide Powder Coating in Screw Barrel?

A screw-Barrel set plays a vital role in plastic processing as raw plastic melt inside the barrel and rotate through the screw. Plastic business is one amongst the most competitive businesses in the world that demands a non-stop and constant production at desired output rate. Stopping the production due to screw or barrel abrasion is […]

Screw Breakage: Extrusion

Extrusion screws very seldom break. But when they do, what are the causes? Your first guess might be that the screw was compromised due to over-torquing, but in reality bending causes more breakages than over-torquing. Over-torque failures almost always occur in the feed section, which makes sense because that is screw section most susceptible to […]
