Research on Stamping and Welding Deformation Suppression Process for Flatness Assurance of Large Shear Cover

This paper investigates the severe warping and flatness deviation of the large shear cover, a primary load‑bearing component of the four‑wheel alignment scissor lift, after welding stiffeners. Through thermo‑mechanical coupling analysis of welding mechanisms, it is clarified that transient stress... Read More

Heavy Machinery Project: Forged Tubes for Hydraulic Cylinders

Client & Background A Southeast Asian construction machinery manufacturer needed forged tubes (cylinder barrel blanks) for hydraulic cylinders used in excavators and piling rigs, with large and steady annual demand. The Challenge The tubes must withstand cyclic pressures above 30 MPa,... Read More

Oil & Gas Project: Heat Exchanger Tube Sheets & Pressure Vessel Rings

Client & Background A Middle East EPC contractor building gas processing modules needed forged tube sheets for shell-and-tube heat exchangers and seamless forged rings for separator vessels. The Challenge Tube sheets up to 1.8m diameter and 320mm thick required thousands of holes in... Read More

Wind Power Project: Tower Flanges & Main Shafts

Client & Background A Northern European wind turbine OEM needed tower connection flanges and main shaft forgings for a 48-unit, 4.5MW-class onshore wind farm expansion. European forge shops could not meet the schedule, so the client searched in Asia. The Challenge Level 1 UT accept... Read More

The critical forgings on the aircraft

In aircraft manufacturing, forgings are the core components that determine the performance, reliability, lifespan, and economy of an aircraft. By weight, the forgings used in aircraft account for approximately 20% to 35% of the total weight of the aircraft's structure. The forgings in aircraft a... Read More

The alloy materials selected for the components of wind turbine generators

A high-quality forged component is far more than just a dimensionally compliant metal blank—it represents the perfect integration of materials science, plastic deformation technology, and precision control.A high-quality forged component is far more than just a dimensionally compliant metal blan...

The alloy materials selected for the components of wind turbine generators

What alloy materials should be selected for wind turbine forgings? As a critical component in wind power generation units, the performance and quality of wind turbine forgings directly affect the stability and operational efficiency of the entire wind power system. With numerous types of alloys... Read More

What is the difference between forged and cast components?

In mechanical manufacturing and materials engineering, forged and cast components are like the "bones" and "flesh" of industrial giants. Although both are core metal forming processes, their fundamentally different physical principles result in distinct application domains. The most fundamenta... Read More

Simulation of forging processes for titanium alloys and typical forgings

With the rapid advancement of aviation technology, aerospace metal materials face pressing demands for lightweight performance, long service life, and excellent environmental adaptability. Titanium alloys, as a novel lightweight material developed over recent decades, exhibit superior properties... Read More

Waveform Analysis of Defect Types in Non-destructive Testing

During routine non-destructive testing of ring components, a company observed abnormal waveforms during inspection. The defect-related waveform is shown in Figure 1, which was compared with standard crack defect waveforms commonly encountered in daily inspections (Figure 2). Comparative analysis... Read More

Defect Analysis of the 40CrMnMoA Roll Shaft Forging

The roller shaft is made of 40CrMnMoA steel with a net weight of 36.6 tons, manufactured from a 60.5-ton steel ingot. Its manufacturing process includes: smelting, casting → forging → post-forging heat treatment → rough machining → ultrasonic testing. During ultrasonic testing, continuous defects... Read More
