Application Fit & Engineering Value
Mining machinery parts must endure extreme conditions: high-impact loading, abrasive slurry, temperature fluctuations, and repetitive stress cycles. Our casting and forging processes deliver directional grain flow and dense microstructures that outperform standard machined or fabricated parts in fatigue life and wear resistance.
- Wear life: High-chromium cast iron and manganese steel grades extend service intervals for bucket teeth, crusher liners, and hammer heads.
- Impact resistance: Alloy steel forgings (e.g., 4140, 4340) with controlled heat treatment provide toughness for shafts, gears, and structural components.
- Corrosion/heat resistance: Stainless steel and heat-resistant alloys suit metallurgical and chemical processing equipment.
- Precision fit: Investment casting achieves ±0.1 mm accuracy and Ra 6.3 μm surface finish, reducing machining allowances.
Critical Specifications & Quality Assurance
We operate under an ISO9001:2000 quality management system. Our quality control includes:
- Raw material certification with traceability to mill test reports.
- In-process dimensional inspection using CMM and gauges.
- Non-destructive testing: X-ray, ultrasonic, magnetic particle, and dye penetrant as required.
- Mechanical property verification: tensile strength, yield, hardness, impact.
- Surface finish and coating thickness checks for painted or plated parts.
We can also perform third-party inspection by SGS, BV, or customer-nominated agencies.
Configuration & Customization
Each part is configured to your drawing or sample. We support:
- Process selection: Investment casting (silica sol or water glass), sand casting (green sand, furan resin, lost foam), forging (open die, closed die, impression die).
- Material grades: Carbon steel, alloy steel, stainless steel, high-chromium cast iron, manganese steel, duplex steel, WCC/WCB/LCC, brass, aluminum.
- Heat treatment: Quenching, tempering, normalizing, annealing, carburizing.
- Surface finishing: Machining, polishing, anodizing, hard anodizing, galvanizing, electroless nickel plating, chrome plating, powder coating, painting.
- Secondary operations: CNC machining, drilling, tapping, welding, assembly.
Automation Integration & Installation Support
Our parts are designed for direct fit into existing mining equipment. We provide 3D models (STEP, IGES) for integration into your assembly line or maintenance planning. For large or complex assemblies, we can supply sub-assemblies with matched bores and alignment features to reduce on-site installation time.
Maintenance, Spare Parts & Serviceability
We support scheduled maintenance programs with:
- Consistent repeatability for reorder parts – same material, same dimensions, same heat treatment.
- Documented inspection records for each batch.
- Packaging options: wooden crates, steel pallets, or export-standard cartons with rust prevention.
- Lead time coordination for urgent breakdown replacements.
Information We Use to Configure Your Solution
To prepare an accurate quotation and manufacturing plan, we need the following project information:
| Data Required |
Why It Matters |
| 2D drawing or 3D model (PDF, DWG, STEP, IGS) |
Defines geometry, tolerances, critical dimensions, and machining allowances. |
| Material specification (grade, hardness, standard) |
Determines casting/forging process, heat treatment, and mechanical properties. |
| Annual or batch quantity |
Influences tooling investment, process selection, and unit price. |
| Surface finish & coating requirements |
Affects secondary operations and corrosion protection. |
| Application details (equipment type, operating conditions) |
Helps recommend material upgrades or design modifications for longer life. |
| Target delivery schedule |
Enables production planning and logistics coordination. |
Frequently Asked Questions
What casting processes do you use for mining parts?
We use investment casting (silica sol and water glass), sand casting (green sand, furan resin, lost foam), and forging (open die, closed die, impression die). The choice depends on part complexity, quantity, material, and required mechanical properties.
Can you supply bucket teeth for excavators and loaders?
Yes. We produce bucket teeth, adapters, and cutting edges in high-chromium cast iron and manganese steel. We can match OEM dimensions or custom-design to your machine model.
What quality certifications do you hold?
Our quality system is certified to ISO9001:2000. We perform material inspection, dimensional control, NDT (X-ray, UT, MPI), and mechanical testing. Third-party inspection is available upon request.
Do you offer heat treatment and machining services?
Yes. We provide quenching, tempering, normalizing, and carburizing in-house. We also have CNC machining capabilities for finishing operations such as turning, milling, drilling, and grinding.
What is the typical lead time for a custom casting order?
Lead time depends on part complexity, quantity, and process. Typical first-article delivery ranges from 4 to 8 weeks after tooling approval. We can expedite urgent orders with express service.
