Monitoring and controlling incoming raw materials
As defined by the Normative ISO 9001:2001:2008 about the supplying process, ProGold strictly and carefully controls all incoming raw materials. All our suppliers are checked in order to see if the products provided fulfil the contractual expectations, monitoring all supplies and evaluating them periodically on the basis of the performances offered.

Our acceptance standards are fixed and clearly indicated in our specimens for each raw material, underlining the minimum pureness level, accepted impurity discrepancies and the control methods. All our raw materials come from qualified suppliers, and they are all carefully controlled before use.

Guarantee of final performances’ constancy
The purpose of this purchasing management and control is the same of our Quality System: to win our customers’ satisfaction. To behave according to the normative ISO 9001:2001:2008 is a fundamental condition to fulfil all customers’ expectations about performances constancy.
