ISO 9001:2015 certified quality management. Raw material inspection, hardness testing, dimensional verification, and OEM cross-compatibility validation on every production batch.
Every steel batch undergoes spectrometry analysis to verify alloy composition against OEM-equivalent material standards. Manganese steel (12–14% Mn) for standard teeth; chromium-molybdenum alloy for rock-grade applications.
Rockwell C (HRC) hardness testing on 100% of heat-treated parts. Standard teeth: HRC 48–52. Rock teeth: HRC 52–56. Test certificates available on request for every batch.
CMM (coordinate measuring machine) inspection of critical mounting dimensions. Pin bore tolerance: +0.05mm / -0.00mm. Ensures drop-in fitment with OEM adapter systems.
Every ESCO part number is validated against original OEM part dimensions, weight, and mounting configuration. Our database covers 5,000+ cross-references to Caterpillar, Komatsu, Hitachi, Volvo, and Liebherr systems.
Charpy V-notch impact testing at -20 C on all mining-grade teeth and adapters. Minimum 27 J at -20 C ensures ductile performance in cold-climate mining operations.
Every part carries a heat number linking it to raw material batch, furnace record, heat treatment parameters, and quality inspection report. Full traceability maintained for 10 years.
