VARISTORS MANUFACTURING PROCESS
In order to guarantee top performance and maximum reliability, close in-line control is maintained over the automated manufacturing techniques. The manufacturing process flow chart shows each step of the manufacturing process, clearly indicating the emphasis on in-line control. Each major step in the manufacturing process shown in the Manufacturing process flow chart is described in the following sections:
MILLING AND MIXING
Incoming materials are checked, weighed, milled and mixed
for several hours to make a homogeneous mixture.
GRANULATION
A binder is added to produce larger granules for processing.
PRESSING
The surface area and thickness of the disc help to determine the final electrical characteristics of the varistor, therefore
pressing is a very important stage in the manufacturing process. The granulated powder is fed into dies and formed
into discs using a high speed rotary press.
For custom specifications, or order individual replacement units, entire grids with various mounting configurations, please contact us to discuss the details.
