Dear Brothers & Sisters,
Greeting of the Day..
I need your assistance regarding Process Validation - Injection Moulding Process (Special Process - where the resulting output cannot be verified by subsequent monitoring or measurement)
We are the manufacturers of Kitchen Cutlery Items (Spoon, fork, knife, etc.,), Plastic Cups & plates. As per the ISO 9001:2015 - 8.5.1.f (process validation / revalidation) we need to have this practice but it is not our customer or regulatory requirement for us.
1) For our industry, it is required to perform process validation / revalidation?
- If so, 2) My question is how to perform this validation process hence we have already set the parameters (Machine, Process),
I have suggested the following steps, to perform validation:

I have suggested the following steps, to perform validation:
- For Maintenance, Ensure the machine parameters that matching with the Machine Supplier requirements (IQ purpose)
- I suggested my production team to do the following:
(i) Identify the CPP (Critical Process Parameter) & CQA (Critical Quality Attributes) involved in it.
(ii) Perform Failure Mode Effective Analysis (FMEA - Process & Product) particularly for CPP & CQA.
(iii) Perform Trial production and record the data ( for OQ purpose)
(iii) Collect the data for short term study (Sample lot / batches)
(iv) Perform Initial Capability Study to ensure the Cpk < 1.33 and approve the process
(v) Collect the data for long term study (Samples from Continuous regular production on a daily basis up to subgroup level) (CPV)
(vi) Perform Ongoing SPC Study to ensure the Ppk < 1.67 and Validate the process.
- Prepare a revalidation criteria to do revalidation when and where required and follow the above activity to revalidate the process.
