• A  toggle  is  mechanically  device  to  amplify  force. • In  a  moulding  machine,  which  consists  of  two  bars joined,  together  end  to  end  with  a  pivot  . • The  end  of one  bar  is  attached  to  a  stationary  platen, and  the  other  end  of  a  second  bar  is  attached  to  the movable  platen. • When the  mould  is open,  the  toggle  is  in  the  shape  of  a  V. • When pressure  is  applied  to  the  pivot,  the  two  bars  form a  straight  line.

PE is made up from Ethylene monomers. PE is divided into different class according to their density. Different types of PE are as below: ( Polymers )                   ( Density ) LDPE               0.910 -0.940 (g/cc) LLDPE             0.915 -0.925 (g/cc) MDPE              0.926 -0.940 (g/cc) HDPE               0.941 -0.959 (g/cc) VLDPE             0.880 -0.915 (g/cc) UHMWPE        0.930 -0.935 (g/cc) Properties of PE: √ Very low cost √  Excellent chemical resistance √  Very good processability. √  High impact s...

√ The function of the torpedo is to help the material for proper melting and crate back pressure for help in mixing. Torpedo used Vartical Hand Injection Machine .

1. A devices made of two dissimilar metals which are used to measure the temperature of a heated area such as the barrel or nozzle. 2. It sends a signal to controller which then turns off or  on to control the temperature of that area.

1. Parts can be produced at high production rates.  2.Large volume production is possible. 3.Relatively low labour cost per unit is obtainable.  4. Part require little or no finishing.  5. Many different surface, colours, and finishes are available.  6. Good decorations is possible.  7. For many shapes this process is the most economical way to fabricate.  8. Process permits the manufacture of very small parts which are almost impossible to fabricate in quantities by other methods. 9. Close dimensional tolerances can be maintained.  10. Parts can be moulded with metallic and non-metallic inserts.

√ Advantages - { injection Blow Moulding } 1. Accurate shaping of the neck. 2. A High level of dimensional accuracy. 3. Mini weight tolerance. 4. The highest quality surface finish. 5. Production absolutely free from waste. 6. Crystal clear containers for pharmaceutical  application. 7. Finished bottle without weld line and scrap. 8. Secondary /finishing operation can be avoided. 9. Multi-cavities can be operated. √ Disadvantages -{ injection Blow Moulding } 1. The preform design generally establish the core rod length & diameter. 2. The process is more expensive than extrusion blow moulding. 3. Compromise between preform wall thickness and blow up ratio. 4. The ratio of the maximum wall thickness to minimum wall thickness across a preform cross-section should be less than 1.5 to prevent weld lines. 5. Preform thickness greater than 6 mm is unstable during blowing since the thick section cannot be properly conditioned. 6. The technique is not suit...
