A Guide To Twin Screw Extruders: Working, Testing & More

 


Have you ever wondered how researchers, universities, and textile laboratories process and test new materials with high accuracy?

One of the most important tools used for this purpose is the twin screw extruder, a machine that helps you study how polymers, fibers, and additives behave under heat and pressure.
Whether you work in a research institution, teach material science, or manage quality control in a textile or plastics facility, understanding this equipment is essential for producing reliable results.
A twin screw extruder—also called a screw extruder or double screw extruder—allows you to mix, melt, and analyze different materials with great precision. This is why it is widely used for polymer development, product testing, and laboratory-scale experiments.
If you want consistent data, efficient processing, and accurate material behavior analysis, choosing the right extruder becomes a key part of your work.
This article will cover everything you need to know before selecting the right machine.

What is a Twin Screw Extruder?

A twin screw extruder is a specialized machine used in research laboratories and industry to process, mix, and analyze polymers, fibers, and other materials.
It consists of two intermeshing screws that rotate inside a heated barrel, applying both mechanical shear and heat to melt and blend materials efficiently.
Unlike a single screw extruder, the twin screw design ensures better mixing, uniform temperature distribution, and precise material handling.
It is widely used for polymer compounding, fiber reinforcement, additive dispersion, and laboratory testing.
By controlling temperature, screw speed, and feed rate, a twin screw extruder allows you to study material behavior and evaluate quality.
It also helps produce consistent, reproducible results for research, quality control, and industrial applications.

Dry vs Wet Sieving in Geotextile Test

Image
Sieving refers to the process of separating a mixture of different particle sizes into several different particle size levels through a perforated sieve surface. After weighing them separately, the particle size distribution expressed as a mass percentage can be obtained. According to the different moisture content of the powder, it is mainly divided into two categories: dry sieving and wet sieving. The following will introduce the definition of dry sieving and wet sieving, the operating steps and equipment required to test the aperture of geotextiles using these two methods, and the difference between the two methods. Dry sieving What is dry sieving Place the dry powder material in the screening equipment, and use mechanical vibration and other methods to make the powder pass through the screen. After the screening is completed, the weight of the screen residue and the weight of the material on the bottom of the screen are counted. The sum of the two is then subtracted from the weight...

Understanding the Jigger Dyeing Machine: Efficiency in Textile Dyeing

Image
There are many ways to color fibers before weaving. Traditionally, you’d dye the entire yarn or apply the color to the fiber. But, how do you dye fabric that is weaved? The short answer –  jigger dyeing machine. Jigger dyeing machine or a jig uses a pool of dye liquor through which a woven fabric passes onto a roller where dye gets absorbed into the fabric. What Is Jigger Dyeing Machine? The jigger machine works on the basic principle of passing the woven fabric through dye liquor back and forth until the dye penetrates the fabric weave. There are multiple rollers in a jigger dyeing machine that pass the fabric through the dye liquor and wound it after an even number of passes. Components of a Jigger Dyeing Machine Dyeing rollers Dye liquor bath Guiding rollers Tension pullers to avoid wrinkles Heating mechanism Chemical injection The woven fabric is wound onto one of the dyeing rollers and fed through two small guiding rollers and the jigger machine wounds the fabric from one roll...

Selection of materials for jigger dyeing machine parts

Image
In the textile industry, the jigger dyeing machine is a key textile printing and dyeing equipment. The selection of its main manufacturing material has a vital impact on the performance, durability, and dyeing effect of the equipment. Stainless steel is one of the most commonly used materials in modern dye jigger manufacturing, especially 304 and 316L. Material selection for each component of the jigger dyeing machine The jigger dyeing machine is composed of a frame, an electric control cabinet, a vessel/top cover, a circulation system, a dye bath, a main roller, a guide roller, a tension frame, an additional tank, a debatching device, and other parts. More details about jigger dyeing machine in our company No contact with dye solution ​ For parts that are not in contact with the dye solution, the main consideration when choosing the manufacturing material is the use environment of the equipment. Generally speaking, the environment of the dyeing factory is harsh. We recommend using 304...
