Extrusion defects-  There are many defects occurs during material Extrusion due to many reasons, For example, poor material mixing, no proper material selection, overheating, etc. Some major defects are given below Center burst/internal cracks Surface cracking piping/Extrusion defects Center burst/internal cracks- Cen…

Cam- Cam is mechanical member for transmission of desired motion to a follower by direct contact. The driver is called cam and driven member is called follower. Types of followers- It may be divided on different basis. 1 on the basis of construction and surface in contact 2. On the basis of type of motion 3. On the b…

Extrusion Extrusion is a process used to create objects of a required cross-sectional profile. A material (may be metal or nonmetal) is pushed through a die of the desired cross-section. Extrusion may be continuous (theoretically producing indefinitely long material) or semi-continuous (producing many pieces). The extrusion pr…

The Phases of a Project Project Initiation Phase- Problem identification phase A project is formally started, named and defined at a broad level during this phase.  Project sponsors and other important stakeholders due diligently decide whether or not to commit to a project.  Depending on the nature of the project, fea…

Thermodynamics Thermodynamics can be defined as the science of energy. The name thermodynamics stems from the Greek words therme (heat) and dynamis (power), which is most descriptive of the early efforts to convert heat into power. Today the same name is broadly interpreted to include all aspects of energy and ene…

Forging Forging is a deformation processing of materials through compressive stress.  F orging is the process of forming and shaping the  metals through the use of hammering, pressing or rolling. It is carried out either hot or cold. Hot forging is done at temperatures above recrystallization temperatures, typically 0.6 Tm, o…

Radiation- The radiation is the emission of energy as electromagnetic waves. It carries heat energy in the form of packets of energy. These  packets  are called photons.    Each photon is a discrete entity of electromagnetic radiation Blackbody- A  blackbody  is a hypothetical/idealized physical  body  that absorbs all inci…

Stefan Boltzmann law- According to Stefan Boltzmann law, the total emissive power of a black body is directly proportional to the 4th power of the absolute temperature of the black body. So, for two blackbodies 1 and 2 with different temperature.  {E1/E2}= {T1/T2}^4

Rheometer   A rheometer is used for torque testing of vulcanized rubbers. The testing process is very easy and reliable. It is fully computer operated the machine More than 30 items of data, such as ML, MH, TS, TC, and CRI, etc. It could be taken from each test. SQL database with the open data table design. it  Enterprise th…
