Tongball's Four Core Commitments

Independent Testing The testing department operates independently from the production system - with separate procurement and personnel certification processes, and monthly precision verification of all equipment. Calibration frequency is twice the ISO 10012 standard.

Primacy of Data Measurement data serves as the core basis for production decisions; all disputes are resolved based on objective data. Customer standards are always prioritized, with measurement resolution 10 times finer than tolerance requirements.

Complete Traceability All measurement data can be traced back to national standards through an unbroken traceability chain. Any quality concessions require prior written approval from the customer.

Independent Reporting The Chief Quality Officer reports directly to the CEO, holding veto power over all shipments. Free from production-related interference, the CQO has final decision-making authority on all quality matters.

Quality Begins Before Machining

We verify every raw material before it enters our production line-from duplex steel and Hastelloy to Inconel and titanium.Our incoming inspection protocol ensures complete traceability and zero compromise on performance:

Tensile Test

Impact Test

Spectrum Analysis

Metallographic Inspection

Material Traceability(10-year archive)

Precision at Every Step

We continuously monitor every machining operation to maintain geometric accuracy and dimensional stability.Realtime adjustments ensure each process stage meets our strict quality standards:

First Article Inspection

Inprocess CMM Verification

Roundness&Concentricity Check

Diameter Tolerance Monitoring

Tool Wear Monitoring

Ensuring Coating Integrity

We verify every substrate before spraying because surface preparation is critical to coating performance.Each check guarantees optimal bonding:

Cleanliness Inspection

Visual Defect Check

Oil/Grease Residue Test

Surface Activation Verification(when required)

Validating Coating Quality

We put every coated component through comprehensive testing to confirm durability and rule out internal flaws:

Coating Thickness Measurement

Bond Strength Test

Porosity Evaluation

Non-destructive Testing(ultrasound if required)

Visual&Dimensional Check

Final 100%Quality Assurance

We subject every finished ball to full inspection before release,guaranteeing conformance to our stringent performance standards:

CMM Full Geometry Inspection(roundness,sphericity,concentricity,diameter)

Surface Roughness Test

Seal Performance Test

Dimensional&Visual Final Check

Validated for Extreme Conditions

We put our components through rigorous thermal shock testing-not just to meet standards,but to prove ourselves.Passing these extreme trials confirms what we've always believed:our mastery of materials,coatings,and precision engineering delivers reliable performance where it matters most.

Predictive Quality & Global Services

Predictive Quality Analytics

Analyzing 50,000+ historical records, our AI system predicts deviations with >95% accuracy, enabling preventive adjustments that reduce non-conformance by 73% vs industry average.
