latest company case about Zibo Tongpu Vacuum Equipment Co., Ltd. Certifications

The lost foam casting production line for wear-resistant castings—such as jaw plates, hammer heads, and similar components—demonstrates significant improvements in performance, excellent process flexibility, and superior economic benefits due to its unique production method and adaptable technical configurations. This process markedly enhances casting quality, reduces downstream processing costs, and allows flexible integration of advanced surface strengthening technologies.

The wear-resistant casting lost foam production line performs particularly well in the following application scenarios:

1.Direct Cost Savings from High Precision and Quality

High dimensional accuracy (CT5–CT7) and excellent surface finish (Ra 6.3–12.5 μm) significantly reduce machining allowances, directly lowering machining time and tool wear. For complex wear-resistant components such as shot blasting machine blades, both surface quality and internal density are superior to those achieved by traditional sand casting.

2.Drastic Reduction in Post-Casting Grinding Work

By eliminating parting lines and defects caused by sand cores—such as flash, burrs, and mismatch—the cleaning and grinding workload after shakeout can be reduced by more than 50%. This not only lowers labor costs and dust pollution but also shortens product delivery cycles.

3.Exceptional Process Flexibility and Efficiency

The lost foam process is highly suitable for new product development or redesign of existing products. Design modifications can be implemented simply by adjusting the foam patterns, without the need for costly wooden or metal molds.

4.Ideal Platform for Advanced Surface Composite Technologies

The characteristics of lost foam casting enable seamless integration with advanced technologies such as Self-propagating High-temperature Synthesis (SHS). During pouring, a high-performance wear-resistant coating can be synthesized in situ on the casting surface, achieving integral formation of the substrate and wear layer. This opens new pathways for producing composite castings with ultra-high wear resistance.

Distinctive Characteristics Compared with Other Lost Foam Casting Lines

Compared with other lost foam casting production lines, wear-resistant casting lines present specific challenges and requirements for line layout and equipment selection:

1.Longer heat retention time for castings

2.Higher molding sand temperature

3.Certain products require integration with additional process technologies, such as vibration-assisted pouring or pre-burning followed by pouring

Overall, wear-resistant castings often require composite modification treatments or specialized heat treatment processes to fully realize the material’s potential. Choosing a lost foam casting production line for wear-resistant castings is not merely the selection of a precision forming process—it is a strategic choice toward higher quality, lower overall cost, and stronger product competitiveness.
