Tight Tolerance Molding
Most of WCPI’s customers require tight visual and/or dimensional tolerances for their products. Dimensional tolerances on some gears are as tight as 30 microns. On some threaded valve stems, dimensions are kept to a variance of 0.003”.
Color match is also very critical. WCPI runs many different custom colors for various customers that are required to meet various L,a,b specifications.
We use 4-component Maguire gravimetric blenders, and automatic or periodic color measurement to ensure color consistency.
