Quality Control

Technical Features:

• Full-process traceability. Complete test records are reserved for each batch from raw material incoming inspection to finished product delivery.
• Hardness test, metallographic analysis, dimensional inspection, UT ultrasonic test and MT magnetic particle NDT are available.
• Detect casting defects such as porosity, sand holes and cracks in advance.
• Strict heat treatment control to stabilize hardness and impact toughness for extended wear service life.
• Random full dimensional inspection of finished goods to meet drawing tolerance for proper assembly.
• Material test reports and NDT certificates can be provided for export and mine acceptance.
• Third-party inspection is acceptable to meet strict requirements of South American mining projects.

Built-in Library:

1. Material formula library: Mn13Cr2, Mn18Cr2 high manganese steel, high chromium cast iron and other wear-resistant material formulas.
2. Heat treatment process library: quenching & tempering parameters for dry / wet grinding and impact wear conditions.
3. Dimensional tolerance library: tolerance specifications for standard & custom parts including ball mill liners, jaw plates, concave and sieve plates.
4. Defect criterion library: casting defect classification and NDT acceptance criteria complying with international mining spare part standards.
5. Working condition case library: field wear data from mines in Chile, Peru and other South American countries to support product optimization.
