Quality means success

Quality Management System

Quality management system within Guarniflon® is an essential part of all processes and activities and is crucial to the success of our business. A specialized Quality team consisting of people with many different skills manage an effective and efficient system controlling every phases of the development & manufacturing processes ensuring the best possible quality of our products and services.
The guiding principles of our Quality Management System involve the entire organization for:
  • Meeting customers expectations and requirements;
  • Improving process control;
  • Lowering costs;
  • Increasing market share;
  • Reducing wastage;
  • Improving the business environment

Since 1993, Guarniflon® is working according to the requirements of ISO 9001and is regularly audited and certified by KIWA CERMET. Moreover to guarantee the fulfillment of the customer’s specifications and requirements regular process audits in our manufacturing facilities are conducted internally by the Quality Management Team and by customers’ auditors.

The commitment to our Quality Policies is one of the critical task for all our employees who makes an active contribution to the overall quality objective and customer satisfaction.
A set of advanced quality tools and instruments for process control and improvement help Guarniflon® to improve the quality of process output by reducing the causes of defect and by improving the consistency in manufacturing and business processes:

  • Statistical Process Control (SPC)
  • Failure Mode and Effects Analysis (FMEA)
  • Production Part approval Process (PPAP)
  • 100% optical and automatic selection
  • Well-equipped laboratories

SPC system installed in the machining department and in the QC laboratory applies statistical methods to the monitoring and control of PTFE machined products production. Monitoring and controlling this process ensures that it operates at its full potential making as much conforming product as possible.
FMEA is a tool for evaluating a process to identify where and how it might fail and to assess the relative impact of different failures, in order to identify the parts of the process that are most in need of change. Guarniflon® use FMEA to evaluate processes for possible failures and to prevent them by correcting the processes proactively rather than reacting to adverse events after failures have occurred.

The purpose of PPAP is:
to ensure that a supplier can meet the manufacturability and quality requirements of the parts supplied to the customer;
to provide evidence that the customer engineering design record and specification requirements are clearly understood and fulfilled by the supplier;
to demonstrate that the established manufacturing process has the potential to produce the part that consistently meets all requirements during the actual production run at the quoted production rate

To fulfill the stringent requirements of the zero defect selection Guarniflon® uses different visual automatic DOSS-machines sorting finished parts through a screening inspection before the final shipment.

Four different laboratories within Guarniflon® organization are specifically fitted with the most updated instruments for testing and analyzing incoming, in process and outbound products and materials. With more than 30 instruments and about 20.000 analysis/year Guarniflon® quality team can guarantee the best and reliable control of our final product.
