Let us understand the factors influencing quality consistency in processing and quality in performance





Characteristics of Polymer

Design factors in Part and; Mould

Specification to meet the requirement of Part and; Mould

  • Maximum shot capacity of plasticating unit,
  • Residence time,
  • Maximum injection rate,
  • Number of stroke controlled steps for filling phase,
  • Maximum injection pressure,
  • Number of time controlled steps for pressure phase,
  • Plasticating rate,
  • Clamp force.

Let us understand moulding problems.

Let us see the analysis of plastic part failurs carried out by RAPRA.
