Dandong Pengxin Introduces World Leading Static Pressure Automatic Production Line for Casting Services

In a significant advancement for the global manufacturing sector, Dandong Pengxin has launched a state-of-the-art Static Pressure Automatic Production Line for its casting services. This integration of German and Japanese technologies establishes a new benchmark in the production of high-integrity castings for automotive, machinery, and heavy-equipment sectors. By combining digital precision with robust engineering, the facility now delivers cast components with exceptional metallurgical consistency, dimensional accuracy, and performance reliability.

Advanced Material Compatibility and Performance
The static pressure molding line enables the production of castings from diverse high-grade materials, including:

• High-Tensile Cast Iron: Grades such as HT250 and HT300, ideal for components requiring high strength under load.

• Ductile Iron (Nodular Iron): Used for parts demanding superior impact resistance and fatigue strength -1-7.

• Special Alloy Irons: Alloys tailored with elements like chromium or molybdenum for enhanced wear or corrosion resistance -1.

These materials are melted in modern medium-frequency electric furnaces (1.5-ton and 3-ton capacities) under precise thermal and chemical control -1. The resulting castings exhibit:

• High Damping Capacity: Effectively absorbs vibrations for smoother machine operation.

• Excellent Wear Resistance: Ideal for components in constant frictional contact.

• Good Pressure Tightness: Essential for hydraulic components and pressure housings.

• Superior Machinability: Allows for efficient post-casting CNC machining to tight tolerances -1-7.

Precision-Driven Static Pressure Casting Process
The production line employs an automated static pressure molding system, a globally recognized green sand molding process known for producing molds with high uniformity and density -4. Key stages include:

1. Automated Mold Production: The line features a high-efficiency static pressure automatic molding unit capable of producing molds with dimensions of 1000×800×350/300 mm at a rate of 90 molds per hour -1. The static pressure process uses compressed air to uniformly compact sand, ensuring consistent mold hardness and precise reproduction of complex geometries.

2. Precision Melting and Pouring: Twelve 1.5-ton and 3-ton electric furnaces, configured with series-parallel 12-pulse control, provide high-quality, temperature-controlled molten iron -1. This setup allows for the production of high-grade cast iron and special requirement materials.

3. Integrated Quality Control: The entire process, from charge makeup and melting to spectral analysis, temperature measurement, and tap-out weight, is automatically monitored and recorded using casting management control software -1. Real-time data display on front-line screens enables immediate process adjustments and ensures full traceability.

Secondary Processing and Validation
To deliver finished components, Dandong Pengxin supports the casting line with:

• CNC Machining: A dedicated workshop equipped with machining centers and CNC lathes performs precision boring, milling, and turning -1-7.

• Comprehensive Testing: The in-house physical and chemical testing center, equipped with spectrometers, metallurgical microscopes, universal testing machines, and hardness testers, validates the chemical composition, microstructure, and mechanical properties of every batch -1.

Applications Across Core Industries
This advanced production capability serves a wide range of industrial applications, providing critical components for:

• Automotive and Vehicle Manufacturing: Engine blocks, brake components, and transmission cases -4-7.

• Agricultural Machinery: Durable housings, gearboxes, and implement parts -7-9.

• Pump and Valve Systems: Corrosion-resistant pump bodies, valve housings, and impellers -7-9.

• Mining and Heavy Equipment: Robust components for crushers, conveyors, and earth-moving machinery -7-9.

Commitment to Technological Leadership
By integrating this world-leading static pressure automated production line, Dandong Pengxin reaffirms its commitment to technological innovation, quality excellence, and sustainable manufacturing. This investment empowers global clients to source high-performance cast components that meet international standards, reduce total lifecycle costs, and enhance the reliability of their machinery.
