Analysis of the whole process standard of customized export delivery of precision shear steel plates

Analysis of the whole process standard of customized export delivery of precision shear steel plates

In the global supply chain system, customized export of precision sheared steel plates has become a core demand of high-end manufacturing. As a professional service provider with fully automatic shearing lines, we deeply analyze the three key delivery standards that international customers are concerned about: automated shearing line precision control, customized steel full-process quality control, and steel plate processing precision parameters to ensure zero-error delivery of each batch of export orders.

1. Automated shearing line: the cornerstone of export quality

The fully automatic shearing line with German CNC control system achieves three core breakthroughs:

Accuracy guarantee: laser positioning + servo leveling system ensures that the shearing tolerance is ≤±0.1mm (exceeding the national standard GB/T 1804-m level)

Efficiency improvement: linkage feeding → intelligent slitting → automatic stacking production line, with a daily processing capacity of 800 tons

Surface zero damage: vacuum suction cup transmission + PE protective film covering technology to eliminate transportation scratches

Case: A German car company uses steel for bumper brackets, requiring 2,000 steel plates to have a consistent size error of ≤0.15mm, and achieves 100% compliance through the equipment's own online detection system.

2. Standardized operation of the entire process of customized steel export

STEP 1 Demand confirmation
Establish customer technical files (material certificate/drawing standard/application environment), focusing on:

Conversion of international standards such as ASTM, EN, JIS

Special treatment requirements for rust prevention in shipping environments

Terminal assembly gap compensation parameters

STEP 2 Raw material traceability
Steel plant direct supply + dual quality inspection mode:

Spectral analysis at the factory (PMI detection)

Ultrasonic flaw detection (internal defect screening)

STEP 3 Intelligent production scheduling
MES system automatically optimizes cutting solutions:

Material utilization rate increased to 93%+

Nested cutting error of special-shaped parts <0.3mm

3. Key points for steel plate processing accuracy control

Indicator Export standard Conventional standard Detection method
Straightness ≤0.5mm/m ≤1.2mm/m Laser tracker
Burr height ≤0.03mm ≤0.1mm Industrial microscope
Diagonal deviation ≤0.1%×length ≤0.3%×length Total station mapping
Verticality 89.9°-90.1° 89.5°-90.5° Digital angle ruler

4. Five major protection systems for export packaging
Moisture-proof layer: 0.12mm VCI vapor phase anti-rust film wrapping

Anti-collision layer: honeycomb cardboard + EPE pearl cotton composite lining

Marking system: ISO 780 international handling symbol printing

Bundling standard: stainless steel buckle + PET strapping cross fixation

Container adaptation: pallet size strictly follows 1C/1A box specifications

5. International certification ensures smooth delivery
All export products are equipped with:

Third-party SGS test report (including chemical composition/mechanical properties)

Certificate of origin (non-preferential/preferential FORM E)

Material traceability code (scan the code to view the full process production data)

Comply with IMDG maritime dangerous goods declaration specifications (for special steel)

Conclusion
The core of the export competitiveness of precision sheared steel plates lies in the use of automated equipment to achieve millimeter-level precision control and build a quality trust system with digital traceability. Through 34 export-specific process standards, we have provided customized steel plate processing services with zero return rate to customers in 27 countries around the world, helping China's smart manufacturing precision parts to go overseas efficiently.
