Quality Control

Great quality starts with the highest standards in raw materials and total control of processing. We follow through with strict ISO training and internal audits.

Training

At NPC, the training of our production workers is the “keystone” to our quality and precision production. Our Production Training Department conducts a formal training program, with all new employees, that is up to six weeks in length. Every six months all production workers are evaluated on their quality performance to determine if additional training is needed. As a new product or process is introduced into our system, the training department develops a program to train all existing workers.

Production Standards

Our Processing Control System sets the variable that control the quality of our product. The cleaning of a blender, blending procedures, blending time, extrusion temperatures, RPM, AMPS, classification methods, and the line cleaning method are all documented and followed for each individual color formula and individual customer’s requirements.

Calibration

All measuring devices (i.e. Scales, temperature gauges etc.) are calibrated on a regular ISO certified basis to ensure their accuracy. This occurs, on average, every 90 days.

Quality Standards

All customer requirements regarding shipping or material content are available during the production process and are monitored to ensure each production run meets your individual requirements. Requirements regarding any shipping specifications are also monitored and carried out. This includes packaging specifications, such as plastic gaylords, barrels, bags or super sacks. It also includes delivery schedule requirements, such as bookings, specified delivery hours and restricted days.
