PTFE Properties

PTFE, also known under the brand name Teflon, has the lowest coefficient of friction of any known solid material and melts between 260°C and 327°C. It’s fairly hard and fairly stiff too, so it’s ideal for parts including things low friction bushings to main assembly parts. Thermoplastics often swell just before they melt, so PTFE […]

Plastic Extrusion Process

The extrusion process is a key component of many of our daily activities. It provides the tubing that distributes our drinking water, heats or cools our homes and could deliver life saving medication to a person in need. The process involves the use of polymers (plastics) that when heated change from a solid to a […]

Differences between sintered & unsintered ptfe tape

More popularly known by the brand name Teflon, PTFE, or polytetrafluoroethylene, is an electrical insulator used in making high-grade cable and wire. PTFE tape is revered as a superior insulator for many qualities, including low dissipation, wide temperature tolerance, high-frequency stability, low smoke generation, resistance, dielectric constants and its resistance to flame, chemicals, solvents, moisture […]

How does injection moulding work?

Injection moulding along with extrusion ranks as one of the prime processes for producing plastic articles. It is a fast process and is used to produce large numbers of identical items from high precision engineering components to disposable consumer goods. Most thermoplastics can be processed by injection moulding; the most common materials used include: Acrylonitrile-Butadiene-Styrene […]

Single Screw Extrusion

Extrusion is a process used for creating a product (an extrudate) by forcing a material through a die or an orifice to form a shape, or alternatively an extruder is used to produce semi-finished or finished products. In a thermoplastic extrusion, the material is first softened by heating so that it can be shaped. This […]

How does twin screw extruder work?

Extrusion processing aims to physico-chemically transform continuously viscous polymeric media and produce high quality structured products thanks to the accurate control of processing conditions. Twin screw extruders consist of two intermeshing, co-rotating screws mounted on splined shafts in a closed barrel. Due to a wide range of screw and barrel designs, various screw profiles and […]

UHMW Ram Extrusion Process

UHMW powder is gravity fed into a chamber and a hydraulic ram pushes the powder from this chamber into the die. The die is the shape of the desired plastic, a certain diameter rod, a certain OD and ID tube, or a profile shape. Heaters are employed on the outside of the die to heat […]

Furnace types

Single-stage:A single-stage furnace has only one stage of operation, it is either on or off.This means that it is relatively noisy, always running at the highest speed, and always pumping out the hottest air at the highest velocity. One of the benefits to a single-stage furnace is typically the cost for installation. Single-stage furnaces are […]

General sintering

Sintering is effective when the process reduces the porosity and enhances properties such as strength, electrical conductivity, translucency and thermal conductivity; yet, in other cases, it may be useful to increase its strength but keep its gas absorbency constant as in filters or catalysts. During the firing process, atomic diffusion drives powder surface elimination in […]

Sintering mechanisms

Sintering occurs by diffusion of atoms through the microstructure. This diffusion is caused by a gradient of chemical potential – atoms move from an area of higher chemical potential to an area of lower chemical potential. The different paths the atoms take to get from one spot to another are the sintering mechanisms. The six […]
