What is Blow Molding? A blow molding process is used to produce hollow plastic products such as bottles, containers, and automotive parts. A thermoplastic material is heated in the form of a preform or parison, and then blown into the desired shape using compressed air inside a mold. After the plastic has cooled and solidified, the mold is opened and the finished product is ejected. This process is called blow molding. What Chemicals are in PET Bottles? A type of plastic, PET (polyethylene terephthalate) bottles are typically made from a polymer called PET. Ethylene glycol and terephthalic acid are the two main chemicals used to make PET bottles. A long-chain polymer is formed when these chemicals react together Pet Bottle Manufacturing Process A PET preform, which is a small, tubular plastic piece, is heated until it becomes soft and pliable for blow molding. As the preform is placed into the mold, it is inflated with compressed air to form the bottle shape. Depending on the shape an...

  As we know the torsion Equation Where τ  = Torsional stress induced at the outer surface of the shaft (Maximum Shear stress). r  = Radius of the shaft. T  = Twisting Moment or Torque. J  = Polar moment of inertia. C  = Modulus of rigidity for the shaft material. l   = Length of the shaft. θ  = Angle of twist in radians on a length. From Torsion Equation we can consider It can be written as The polar moment of inertia will be calculated from the following equation. The polar moment of inertia for a circular cross-section is From this, the maximum torque that can be transferred thru the shaft can be written as From the above equation, we can calculate the unknown factors. In our case, the shaft diameter is the unknown factor.

What is Hydroforming ? Hydroforming is a metal fabricating and forming process which allows the shaping of metals such as steel, stainless steel, copper, aluminum, and brass. This process is a cost-effective and specialized type of die molding that utilizes highly pressurized fluid to form metal. Generally there are two classifications used to describe hydroforming, Sheet hydroforming Tube hydroforming Sheet Hydroforming Sheet hydroforming uses one die and a sheet of metal; The blank sheet is driven into the die by high pressure water on one side of the sheet forming the desired shape. Tube Hydroforming If the shape contains bends that deviate from a straight line, the raw tube is loaded into the tube bender. This bends the tube giving it the necessary curvature in order to fit into the dies. The bent Tube is then typically placed in either our 200 or 500 ton pre-form press. These presses will initiate the forming and shape change of the ...

Molding   -   It is the process to make the mould to get a propeller shape. The mold is made from fine sand and Hardener agent. Casting   -   It is a process where molten metal liquid of propeller material such as manganese bronze will ...

How DP Test Works??? Dye Penetrant Examination is commonly used for weld components. In this technique low viscosity liquids are allowed to penetrate in the surface openings and after penetration, liquid is made to extract out again by means of some developers. That is why it is also known as Liquid Penetrant Examination for the evaluation of weldment.  The examination includes five steps ·         Cleaning ·         Introducing Penetrant ·         Penetrant Removal ·         Introducing Developer ·         Examination Cleaning: - To start, the test surface is need to be cleaned with the help of wire brush or some old cloth using a suitable. cleaner. The surface must be cleaned from organic compounds (oil and grease), dust, scale and other pollutants because an even su...
