Process Optimisation

At Avenue, we carry out comprehensive mould testing to establish a robust processing window for each mould.

Our approach to Process Optimisation typically involves:

  • Taguchi, G&A or other statistical technique used to determine key process variables in the design of experiments
  • Process parameter values are established
  • Cp determined

Confirmation – run 1

  • Optimised settings ran to confirm part
    quality is acceptable
  • Critical dimensions measured using contact (CMM) or non contact (optical) measuring equipment to compare results with initial trial

Process capability

  • Critical dimensions measured using contact (CMM) or non contact (optical) measuring equipment to determine Cpk and final mould sizing

Confirmation – run 2

  • If mould re-sizing takes place following process capability, further measurements are carried out to confirm the changed dimensions and to ensure the required Cpk is achieved
