At LONGCHAO, we specialize in precision-engineered heavy machinery forgings designed for durability, structural integrity, and demanding industrial applications. Our end-to-end service process is built around quality, customization, and long-term reliability—ensuring your components meet exacting standards for power, mining, construction, energy, and transportation equipment.

1. Technical Consultation & Requirement Definition

Our service begins with a detailed consultation to understand your technical needs. We analyze application scenarios, load-bearing requirements, mechanical properties, and dimensional tolerances. Whether you’re sourcing forged shafts, gear blanks, connecting rods, or custom parts, our engineering team helps define the forging solution best suited to your industry and operating environment.

2. Material Selection & Metallurgical Planning

LONGCHAO places a strong emphasis on material science. Based on mechanical performance goals—such as strength, impact resistance, fatigue life, or corrosion resistance—we recommend the ideal alloy or steel grade (e.g., carbon steel, alloy steel, stainless steel). Each material batch is traceable and verified for chemical composition and purity.

3. Die Design & Pre-Forging Engineering

We use advanced CAD/CAM and forging simulation software to develop dies and pre-forming processes. This ensures metal flow consistency, grain alignment, and minimal internal defects. Every forging is engineered to reduce post-processing needs while maximizing structural performance.

4. Precision Forging & Controlled Processing

With fully equipped forging lines including open-die, closed-die, and ring-rolling equipment, LONGCHAO performs forging at controlled temperatures with strict process supervision. Our expert technicians ensure each part is forged under optimal pressure and temperature to achieve uniform grain structure and superior mechanical properties.

5. Heat Treatment & Machining Services

Post-forging, each component undergoes customized heat treatment—normalizing, quenching, tempering, or annealing—to achieve the required hardness, strength, and toughness. For clients requiring ready-to-assemble components, we provide CNC machining, surface finishing, and dimensional precision to drawing.

6. Inspection, Testing & Documentation

Quality is at the core of our process. We conduct thorough testing including ultrasonic flaw detection, hardness testing, tensile strength testing, impact tests, and dimensional checks. All forgings are accompanied by full inspection reports and certificates such as EN 10204 3.1/3.2, as required by your project.

7. Packing, Delivery & After-Sales Support

After passing final inspection, parts are packed according to international export standards, with options for anti-rust coatings, wooden crates, and moisture protection. Our logistics team coordinates sea, air, or land freight based on your schedule. LONGCHAO also provides after-sales technical support, ensuring performance throughout the product lifecycle.
