Lab & Instruments
Our in-house quality laboratory is equipped with state-of-the-art instruments that validate every critical parameter — from ball-to-ball variation and surface roughness to roundness geometry and 100% visual inspection — before any product leaves our facility.
DimensionalBall-to-Ball Variation
Precision electro-mechanical gauging system that measures size consistency across every ball in a batch, ensuring sub-micron diameter uniformity.
SurfaceSurface Roughness Testing
High-accuracy profilometer operated by trained technicians to quantify Ra and Rz surface finish values against international grade standards.
GeometryRoundness Measurement
Taylor Hobson roundness tester with an air-bearing spindle delivers nanometre-level sphericity analysis on finished balls.
Visual100% Visual Inspection
Dedicated inspection bay where every ball is examined under magnified illumination by skilled inspectors to detect surface defects before dispatch.
DimensionalDigital Height Gauge
High-precision digital height gauge used for accurate dimensional inspection and measurement of components, ensuring strict adherence to specified tolerances during quality control.
MechanicalTensile & Crushing Load Machine
Advanced tensile and crushing load testing machine used to evaluate the mechanical strength, load-bearing capacity, and durability of balls in accordance with international testing standards.
InspectionMetallurgical Microscope
