Toggle Type Clamping (injection moulding)


• 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.

Breaker Plate & Screen Pack :

Breaker Plate - 1. This is performed metal disk,  with a multitude of small diameter holes. 2. The breaker plate is placed in between the screw and the die assembly. 3. It's principal function is to provide support for the screen pack . 4. The breaker plate helps also to convert the spiral flow of the polymer melts leaving the screw into a linear, axial one. Screen Pack - 1. Screen Pack is usually a multilayered,  nearly symmetrical sandwich of metallic wire screens.  2. It is placed between the screw and the breaker plate,  using the latter for physical support. It's  role is to eliminate the particulate contaminants.  3. The screen pack composition is always based on trade-offs, there is need to eliminate particulates using screens with high mesh,  but at the same time this create flow restriction,  it reduced the throughput, thus low mesh would be preferred.  4. Decision should be made as for as the maximum tolerabl...

Advantage and Disadvantages of Injection Blow Moulding Process

√ 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...
