Durability solution for truck chassis components - FCD cast iron - Disoco

In the automotive industry, especially in the commercial vehicle and truck segment, truck chassis system components belong to the group of parts that bear heavy loads and operate under harsh conditions. These components must simultaneously withstand large static and dynamic loads, continuous vibration, strong impacts, and high fatigue cycles throughout the long service life of commercial vehicles.
Therefore, technical requirements are not limited to high tensile strength but also demand stable fatigue strength, good impact toughness, and uniformity in the metallic structure between production batches. Even a small deviation in chemical composition, graphite structure, or internal defects such as shrinkage porosity or gas porosity can directly affect the lifespan and safety of the entire chassis system.
In such cases, the cast iron component casting technology for trucks requires a high level of technical capability and quality control system.
DISOCO (Song Cong Diesel Limited Company) is an FC, FCD cast iron foundry with long-standing experience in the automotive component sector, featuring an automatic green sand casting system that meets IATF 16949 standards for the commercial vehicle industry.
DISOCO's Cast Iron Casting Capabilities for Truck Components
- Synchronized green sand casting line for truck chassis components
DISOCO owns a synchronized green sand casting system, including both automatic and semi-automatic lines, flexibly meeting the production requirements for truck chassis system components from medium to large sizes.
The automatic SINTO (Japan) green sand casting system has a capacity of 10,000 tons/year, a molding speed of 30 seconds/mold, ensuring high mold stability and repeatability in mass production. Additionally, the semi-automatic line with a capacity of 5,000 tons/year and a maximum flask size of 900x600x500 mm allows for the production of chassis parts weighing up to 100 kg.
- In-house mold design and casting simulation
DISOCO has a team of design engineers and specialized software systems such as CATIA 3D and SOLID Cast for designing and simulating the casting process. The ability to design molds and simulate metal flow from the initial stage helps optimize the gating and riser system, reducing shrinkage porosity and internal defects, especially for thick-walled and high-load chassis components. Proactive in-house design also helps shorten product development time and enhance stability in mass production.
- IATF 16949 certified quality control system
DISOCO applies a quality management system according to IATF 16949 standards, along with ISO 9001, ISO 14001, ISO 50001, and ISO 45001 certifications. The factory is fully equipped with inspection equipment such as a spectrometer, ultrasonic NDT, magnetic particle inspection (MPI), tensile testing machine, hardness tester, Mitutoyo 3D CMM, and metallurgical microscope. This control system ensures that the chemical composition, mechanical properties, and dimensions of FC, FCD cast iron products meet the stringent requirements for truck and commercial vehicle chassis system components.
Given the characteristics of heavy loads and high fatigue cycles, truck chassis system components require cast iron solutions with superior strength and stability. Thanks to its synchronized green sand casting system, in-house mold design and simulation capabilities, and IATF 16949 certified quality control, DISOCO not only meets the strict technical requirements for truck components but also provides a sustainable solution for commercial vehicles demanding high safety and long-term operational lifespan.
