Ductile iron base - casting and machining

QT450 Industrial Equipment Casting Base

This product is a high-strength, high-toughness cast iron base designed specifically for heavy industrial equipment.

Made of QT450 ductile iron, combined with precision casting technology and professional surface treatment, this product ensures superior mechanical properties, excellent vibration damping, and an ultra-long service life in harsh industrial environments.

Material: QT450-10 (GB/T 1348) / EN-GJS-450-10 (DIN)

Its graphite is spherical, combining the excellent castability of cast iron with mechanical properties close to those of steel.

• High strength and toughness: tensile strength ≥450MPa, elongation ≥10%. Compared with ordinary gray iron (HT), it has higher strength, toughness and fatigue resistance, and can withstand greater loads and impacts.

• Excellent vibration damping: The inherent damping characteristics can effectively absorb vibrations during equipment operation, protect equipment precision, and reduce noise.

• Excellent wear and corrosion resistance: The dense matrix structure ensures long-term stable operation.

Precision casting, structural optimization

• Process: Precision casting processes such as resin sand or lost foam casting are used to ensure that the castings are dimensionally accurate, have clear outlines, and have a uniform internal structure.

• Casting tolerances: conforming to GB/T 6414 CT8-CT10 grades or as specified by the customer.

• Coating: After rigorous pretreatment (shot blasting to Sa2.5 grade, phosphating or passivation), a high-quality black epoxy/powder electrostatic spray is applied (coating thickness and color can be adjusted according to requirements).

• Protective properties: The coating has strong adhesion and uniform thickness (usually 60-80μm). It has excellent corrosion resistance, chemical resistance and wear resistance, and can effectively resist moisture, oil and workshop environment corrosion.

• Appearance and Safety: Matte or semi-gloss black, with a clean, professional look that meets industrial aesthetic requirements.

High cost performance and customizability

Cost-effectiveness: While providing excellent overall performance, it has a lower manufacturing cost compared to an all-steel welded base .

Fully customized: We can flexibly design and produce according to the equipment drawings or specific requirements (size, load capacity, interface, installation method, etc.) provided by the customer.

Quality assurance: Material reports (mechanical properties, metallographic analysis) and dimensional inspection reports can be provided.

This product is widely used in industrial settings that require stable and robust foundation support.

Machine tool industry: Beds and bases for CNC machine tools, machining centers, milling machines, and grinding machines.

Automation and Robotics: Industrial robot bases, automated production line frames, and testing equipment platforms.

Collaborative Design Management (DFM): Provides casting processability review and optimization suggestions to help customers achieve the best design.

Full-process quality control: From mold making, melting and casting, heat treatment (normalizing or annealing), machining (if required) to surface treatment, full-process inspection is implemented.

One-stop delivery: Supports different delivery states from raw castings to finished products (such as guide rail milling, drilling and tapping).

On-time delivery: Relying on a mature supply chain and production plan, we ensure on-time delivery of orders.
