First Shot Samples Polished before the Buyer Ever Sees Them
Doctored T1 samples hide draft and thermal flaws through hand polishing; enforce raw steel T0 audits with continuous cavity telemetry before sign-off.
White Light Optical Point Cloud Scanning
Meaning
A non-contact measurement technology uses structured light patterns and digital cameras to capture the three-dimensional surface coordinates of a molded plastic part. This inspection method, known as white light optical point cloud scanning, governs dimensional validation by generating a dense mesh of millions of data points that can be compared directly to the CAD model. The process applies to complex, warped, or flexible plastic parts and is less effective on highly transparent or high-gloss surfaces that distort the light patterns.
Dimensional Metrology
Projected light fringes deform as they strike the surface of the plastic part while high-resolution cameras record these distortions. White light optical point cloud scanning uses these images to calculate the coordinates of the surface. This method captures entire freeform shapes much faster than traditional touch-probe coordinate measuring machines.
Tooling Qualification
Engineers use the scan data to generate color-coded deviation maps that show areas of sink, warp, or dimensional drift. This visual feedback helps mold makers adjust the steel dimensions of the mold core or cavity. It allows the development team to quickly identify tool corrections needed to achieve target part tolerances.
Quality Inspection
Fast scanning speeds enable molding shops to check production parts during start-up trials and routine quality audits. Dimensional deviations caused by cooling rate changes or material batch differences are detected before the parts are shipped. This scanning helps the facility maintain tight process control without slowing down the release of production lots.
