Product Description

Core Material Advantages

We primarily adopt high-quality carbon steel grades, with 45# carbon steel as the most widely used variant, supplemented by other customizable grades (e.g., 20#, 35#, Q235) to meet diverse application requirements:

Superior Mechanical Properties: Featured with balanced strength and ductility, the as-normalized carbon steel castings have a tensile strength of ≥600MPa, yield strength of ≥355MPa, and elongation of ≥16%.

Excellent Machinability: Good cutting performance with low resistance. Surface roughness can reach Ra≤1.6μm after precision processing.

Cost-Effective & Easily Accessible: Obvious cost advantages over alloy and stainless steel with a mature raw material supply chain.

Customizable Heat Treatment: Hardness and wear resistance can be adjusted (up to HRC55-60) via quenching and tempering.

Advanced Production Process

Manufactured through strict investment casting (lost wax casting) process to ensure international standards:

01 Wax Mold Making: High-quality low-temperature wax used with linear shrinkage ≤0.8% and burr ≤0.03mm.

02 Shell Making: Adopting zircon sand and silica sol, coated with 3-8 layers for high strength and air permeability.

03 Dewaxing & Roasting: High-pressure steam dewaxing (rate ≥99%) and roasted at 1000-1150℃.

04 Melting & Pouring: Vacuum induction furnace melting with real-time spectrometer detection (element deviation ≤0.02%).

05 Post-Processing: Sand cleaning, heat treatment, sandblasting, and pickling for a smooth, defect-free surface.
