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
on their quality performance to determine if additional training is
needed. As a new product or process is introduced into our system, the
department develops a program to train all existing workers.
Our Processing Control System sets the variable that

blending time, extrusion temperatures, RPM, AMPS, classification methods,

individual color formula and individual customer’s requirements.
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.
All customer requirements regarding shipping or material
