- Audit summary on one page for easy reading
We recognize that accurate auditing requires making observations and providing data back to both parties in the customer-vendor relationship. Because it is direct and "to the point", it can often be perceived as harsh criticism. However, we hope that you would use the information to reinforce the many positive aspects of your operation as well as to focus attention toward improvement.
Because this type of audit results in an approximate 30 - 50 page document, extra time must be allowed once the audit is complete. The actual audit process can be completed in one to two days with no interruption of production, depending on the complexity of your powder coating operation. In order to receive a full audit of your facility, please contact your DuPont Powder Coatings salesperson for availability.
