Qiming Casting masters cast threaded holes in high manganese steel & high chrome cast iron. Our stable process creates high-strength threads, eliminates bushing wear & loosening, boosts equipment stability, and increases effective wear thickness. Solve the wobbling issue of traditional bushed holes.
In harsh industrial environments, the mounting points on wear-resistant castings often become the weakest link. Are you also troubled by these issues?
-
Loosening and wobbling of high manganese jaw plates or concaves due to worn bushings, compromising equipment accuracy?
-
The machining allowance for bushings unnecessarily reduces the effective thickness of your wear material, shortening service life?
-
Unreliable traditional cast threaded holes with damaged threads and poor precision, leading to installation issues or even casting scrap?
These problems stem from the limitations of conventional methods. Qiming Casting, with its mature and proprietary technology for casting threaded holes, offers you a revolutionary solution.
Why is Qiming’s Cast Threaded Hole Technology an Industry Benchmark?
Casting high-quality threaded holes directly into challenging materials like High Manganese Steel (ZGMn13) and High Chrome Cast Iron requires extreme precision. It demands deep expertise and exact control over material behavior, mold design, gating systems, and sand core management.
Through years of R&D and practice, Qiming has overcome all technical hurdles:
-
Precision Sand Core Technology: We use custom-made, high-strength, high-precision threaded sand cores that resist deformation and erosion from molten metal, resulting in sharp and fully-formed threads.
-
Tailored Process Solutions: We have developed specific pouring and cooling protocols for the toughness of high manganese steel and the hardness of high chrome iron. This ensures dense microstructure at the thread roots, free from shrinkage or cracks, guaranteeing connection integrity from the start.
-
100% Quality Verification: Every cast threaded hole undergoes professional cleaning and is inspected with thread gauges (Go/No-Go) to ensure dimensional accuracy and ready-for-assembly quality.
Core Benefits of Choosing Qiming’s Cast Threaded Holes:
-
Permanent, Rock-Solid Connection: Bolts engage directly with the casting body, creating a rigid connection. This fundamentally eliminates relative movement and wear between a bushing and the base material, ensuring long-term stability even under the most demanding conditions.
-
Maximized Effective Wear Thickness: By eliminating the need for extra wall thickness and machining allowances for bushings, every millimeter of your wear material contributes to its service life. Our castings last longer for the same specification.
-
Enhanced Structural Integrity: The integrally cast threads avoid the micro-cracks and stress concentrations that can occur during bushing press-fitting, making them ideal for high-impact applications.
-
Reduced Total Cost of Ownership: Enjoy longer part lifespan, significantly reduced downtime for maintenance, and more stable equipment performance, delivering superior long-term value.
Application Areas:
Our technology is successfully implemented in key equipment across mining, cement, metallurgy, and construction machinery industries, including: VSI Shoes, Impact Plates, Side Plates, Excavator Bucket Teeth, Blades, Roller Press Rolls, and more.
Say goodbye to bushing loosening. Experience the strength of monolithic construction.
While other foundries still consider cast threaded holes in high manganese/high chrome steel a “no-go zone,” Qiming Casting has perfected it into a stable and reliable standard process.
