Mining Machinery Sand-Cast & Forge Parts

Mining Machinery Parts by Sand Casting And Forging – Core Introduction

Brief Introduction to the Product

Qingdao Chifine Machinery specializes in mining machinery parts via sand casting and forging, delivering durable, high-performance components for the mining industry. With 10+ years of experience, we use materials like grey iron, ductile iron, malleable iron, steel, and aluminum, supporting part weights from 1kg to 2 tons—critical for heavy-duty mining equipment. Our services comply with ISO9001 standards and casting grades CT6-CT9, aligning with ISO, DIN, ANSI, BS, and JIS benchmarks.

Key Features of the Product

Dual Manufacturing Processes: We combine sand casting (with resin sand, hot sand, green sand options) and forging to produce parts. Sand casting suits large, complex parts like crusher housings, while forging enhances strength for high-wear components like bucket teeth—ensuring parts meet mining machinery’s demanding performance needs.

Rigorous Quality Control: We conduct 100% inspection before production (raw material testing) and post-production testing (dimensional, mechanical property, UT testing). This two-stage inspection eliminates defects and ensures parts withstand harsh mining environments (dust, impact, heavy loads).

Custom Surface Treatments: Surface treatment options include paint, E-coat, epoxy powder coating, and zinc plating. These treatments protect parts from dust abrasion and moisture corrosion, extending service life and reducing maintenance costs for mining operators.

One-Stop Service Solution: We offer end-to-end service from drawing design and mold making to final finishing and packaging. This integrated service streamlines the supply chain, reduces lead times, and ensures consistency in part quality across all production stages.

High Monthly Production Capacity: We produce 1550 tons of parts monthly, meeting large-volume demands from mining equipment manufacturers. Our scalable production line can adjust to peak demand periods while maintaining delivery timelines.

Mining Machinery Parts by Sand Casting And Forging – Scenario-Specific Applications

Underground Mining Equipment Application

For underground mining (e.g., loaders, drills), we produce ductile iron parts like bucket teeth and drill bits with forging treatment. Forging enhances material density and wear resistance, allowing parts to withstand repeated impact with rock and extend service intervals—critical for minimizing underground mining downtime.

Open-Pit Mining Machinery Application

Open-pit mining machines (e.g., excavators, crushers) require large, heavy parts; we use sand casting with resin sand for components like crusher jaws. Resin sand casting ensures dimensional stability and smooth internal surfaces, enabling crushers to process large rock volumes efficiently without jamming or part failure.

Mining Conveyors Application

Conveyor systems in mines need corrosion-resistant parts; we apply epoxy powder coating to steel conveyor rollers. Epoxy coating forms a tough, chemical-resistant layer that prevents dust buildup and rust, ensuring conveyors operate smoothly to transport ore from mining sites to processing facilities.

Mining Hydraulics Application

Hydraulic components (e.g., cylinders, valves) for mining machinery use steel with annealing treatment. Annealing reduces internal stress and improves ductility, allowing hydraulic parts to withstand high pressure (common in mining equipment) and prevent leakage—ensuring reliable operation of hydraulic systems.

Mining Machinery Parts by Sand Casting And Forging – Technical Backup

R&D Team Support

Our in-house R&D team provides technical support for part design optimization. They analyze mining machinery’s operating conditions to recommend material selections (e.g., malleable iron for flexible parts, hardened steel for wear resistance) and process adjustments (e.g., forging parameters to enhance strength).

Advanced Inspection Tools

We use CMM (Coordinate Measuring Machines) to verify dimensional accuracy, 2D projectors to inspect part profiles, surface roughness testers to check finish quality, and customized gauges for mining-specific part features. These tools ensure parts meet tight tolerances and mechanical property requirements.

Material Expertise & Selection

Our team has deep expertise in mining-grade materials. We recommend materials based on part function: for example, ductile iron for parts requiring impact resistance (e.g., loader buckets) and stainless steel for parts exposed to corrosive mining chemicals (e.g., hydraulic valves in wet mines). This ensures optimal part performance and longevity.

Mining Machinery Parts by Sand Casting And Forging – Supporting Services

24/7 Technical Support Service

We offer online technical support 24 hours a day, 7 days a week. Mining operations run continuously, so our team is available to address urgent issues (e.g., part failure troubleshooting) and provide quick solutions to minimize downtime.

Sample Provision Service

We offer samples before trial orders to validate part performance and fit in mining machinery. Samples are produced using the same processes as mass production, allowing customers to test durability, compatibility, and functionality in real mining conditions.

Global Export Service

We export parts to markets including Eastern Europe, Western Europe, North America, Africa, and Australia. Our logistics team has experience in international shipping and customs clearance, ensuring parts are delivered on time and comply with import regulations in different countries. We also provide necessary documentation (certificates of quality, material test reports) for customs.
