What are Plastics? Plastics are a material that is made up mainly of macromolecules, that can be made fluid by the action of heating and pressurizing, and that can be processed into end products with any useful shape you want to make. Classification of Plastics Plastics can be classified into: 1. Thermoplastics and Thermo sets 2. Amorphous Thermoplastics and CrystallineRead more

Plastics are excellent materials with unique and very useful properties. You can produce just about anything you can imagine using plastics. Characteristics of Plastics History Of Plastics: 1. Before Plastics—Age of the Natural Resins Rubber—Tough elastic substance (light cream or dark amber colored) from the milky juice (sap) of rubber tree Ebonite—Hard black rubber; natural rubber + sulfur Gutta-Percha—Dark brownRead more
Advanced Battery Storage Technology | Ultra Capacitor Battery Storage unit | Barium-Titanate Insulator
For decades, battery storage technology has been a heavy weight on the back of scientific innovation. From cell phones to electric vehicles, our technological capabilities always seem to be several steps ahead of our ability to power them. Several promising new technologies are currently under development to help power the 21st century, but one small start-up looks especially well positionedRead more
Nano Composite Material | Calculate High Cycle Fatigue | Repeated Mechanical Stress Create Stronger Nano Composites
If someone does a lot of arm curls at the gym, the typical result is that the bones and muscles in their arms will get stronger. Recently, researchers at Houston’s Rice University inadvertently created a nano composite that behaves in the same way. Although the material doesn’t respond to static stress, repeated mechanical stress will cause it to become stiffer.Read more
Infrared Curing | Convection Curing | Infrared Heating Systems | Infrared Curing & Drying Technology
The coatings and paint industries strive to provide high technology coatings while reducing volatile organic compounds and energy consumption to produce a finished coating. Conventionally Convection ovens are used to cure the coatings. But this process which uses electric heaters is not an optimal process and is associated with various disadvantages. Improved technologies are available today, which can either replaceRead more
As the standards of our industry rise due to increasing globalization and competition, there is an ever growing need for consistency and reliability. Breakdown of any unit, system or equipment is an avoidable and costly occurrence and must be prevented or minimized. Analysis of such failures becomes a resourceful and affordable tool in addressing such unwanted occurrences.Read more
Why is XRD Important? It’s useful for studying Crystal structure. This method have the details about Grain size (or) Crystal size Orientation of the crystal, Cold worked, Distorted and Internally stressed crystals Re-Crystallization Preferred orientation etcRead more
A crystalline material is one in which the atoms are situated in a repeating (or) periodic array over large atomic distances.
Non Crystalline Materials:
Materials that do not crystallize are called non-crystalline (or) Amorphous materials
Finishing Operations In Manufacturing
Repressing the sintered component in a die to meet required tolerances.
Repressing the sintered component in a die to increase the density and to give additional strength.Read more
What is sintering in powder metallurgy process?
The operation of heating the green compact at high temperature in a controlled atmosphere (Reducing atmosphere which protects oxidation of metal powders). The Sintering increases the bond between the particles and therefore strengthens a powder metal compact. Sintering temperature and time of sintering depends on the type of powders and the strength required in a final product. The Sintering temperatures usually 0.6 to 0.8 times the melting point of powders.Read more
