Extrusion Reprocessing

The term extrusion reprocessing refers to the minimizing of the scrap generation and recapturing of the material value in most of the operations. In almost all types of extrusion processes, it is a common practice to grind up the scrap materials by using granulator or allied suitable equipment. With the usage of this equipment, such granules […]

Basic Extruder Machine

Every extrusion company has its own variation of plastic extruder, but the basic operation of all the machines remains the same. Firstly, there is the feeder zone, which transfers the pellets or powder resin from the hopper to the barrel. The plasticizing unit consist of a feed screw, barrel and temperature controller where the resin […]

Types of Plastic Extruders

Plastic extruders are used to create a wide range of items, including plastic tubing, trims, seals, plastic sheets and rods. Extruder is the machine for producing more or less continuous lengths of plastic sections out of a selected type of plastic resin. There are a number of extrusion techniques available such as co-extrusion, offset extrusion, […]

Plastic Extrusion Machines Introduction & Types & Application

With technical knowledge and engineering skills plastic resin can be converted into any desired shape. Plastic is one such material which in its variety of designs and colours find widespread application in homes and industries. Industries largely use the plastic extrusion process to shape the products, for which a variety of sophisticated extrusion machines with […]

Types of injection molding machines & molding machine process

Molding Machines are classified primarily by the type of driving systems they use: hydraulic, mechanical, electric, or hybrid. Hydraulic Hydraulic presses have historically been the only option available to molders until Nissei Plastic Industrial Co., LTD introduced the first all-electric injection molding machine in 1983. Hydraulic machines, although not nearly as precise, are the predominant […]

PTFE Properties

PTFE resin is in a class of paraffinic polymers that have some or all of the hydrogen replaced by fluoride. The original PTFE resin was invented by DuPont in 1938 and called Teflon®. PTFE is a crystalline polymer with a melting point of about 621° F (327° C). Density is 2.13 to 2.19 gm/cc. PTFE […]

What are the differences between Nylon and PTFE filters?

Nylon membranes for filtration using syringe filter devices and which membrane can be used with different solutions and or sovlents. PTFE as a membrane for syringe filters is considered to be more “chemically resistant” and Nylon to be the most “extractable free” for HPLC or dissolution testing. The simple explanation of the differences is that […]

PTFE Materials & Porous PTFE Plastic Polymer

Polytetrafluoroethylene (PTFE) is a versatile polymer used in a broad range of medical, industrial, and high technology applications. Porous PTFE is inert, making it unreactive to most chemicals, and, it can work in high processing and operating temperature environments (500°F / 260°C continuous). Porex porous PTFE offers excellent thermal, electrical, mechanical, and chemical properties as […]

The physical properties of PTFE

Polytetrafluoroethylene (PTFE) is very non-reactive and is often used in containers holding reactive and corrosive chemicals. According to DuPont, its melting point is 600 K (327 °C; 620 °F). It maintains high strength, toughness and self-lubrication at low temperatures down to 5 K (-268.15 °C; -450.67 °F), and good flexibility at temperatures above 194 K […]

PVC & PTFE Material Comparison

Polytetrafluoroethylene (PTFE) is a synthetic material accidentally invented in the late 1930s while a chemist was endeavoring to develop a new type of perfluorethylene-based refrigerant. Rather than achieving a chlorofluorocarbon, the scientist was surprised to find that the perfluorethylene used in the process reacted with the iron content of its container and polymerized under pressure.
