DIE DESIGN :

Die Design -
1. The role of a die is to from the melt into a desired linear product : fibres, films, sheets, profiles, rods, etc.
2. The die is a channel, whose profile changes from that of the extruder bore to an orifice, which produces the required form.
3. The dies can be classified using different criteria.
    Example - Considering cross section of the extrudate one may recognize dies to produce -
    • Solid Cross - Sections(Click Here)
    • Hollow Cross - Sections

4. Another classification scheme is based on the die attachment to the  extruder barrel -
    • Straight - throught Dies -(Click Here)
    • Cross - heat dies- (Click Here)
    • Offset dies -(Click Here)

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 tolerable size of the particulate contaminan

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 suitable
