I would suggest you start to understand injection molding, engineering and managing available staff and resources.
In this business, no plan is 100% sure until the mold is up and running.
If you want to pass on inaccurate information to a customer then you are risking a bad reputation for Malaplast if something goes wrong with the mold, machine an ancillary part or any other unforeseen event .
I have been given the job of passing information to sales to stop sales giving inaccurate information to customers.
I will give you a plan of action that you can pass on to customers if you tell them that the plan is the objective and not fact until it happens.
