Engineering machinery is widely used in: Excavators / Loaders / Bulldozers Crane / Lifting Equipment Concrete Machinery Road and Mining Machinery Port / Heavy Material Handling Equipment Structural Assemblies & Reinforcing Components Hydraulic Structural Components and Housing Components
Typical characteristics of the industry: Heavy materials, high weld load High requirements for component strength & fatigue life Coexistence of mass production and customization of structural components Multiple batch orders, complex welding structures Long process chains, high reliance on manual labor
Under the pressure of international competition, delivery cycles, and costs, the engineering machinery industry is continuously upgrading from: Traditional welding + flame cutting + manual grinding to laser processing + automated welding + flexible manufacturing.
Industry Challenges
01
High reliance on manual welding, resulting in inconsistent quality.
Continuous welding of large welds leads to welder fatigue. Strength stability depends on manual experience. Rework and grinding costs are significant.
02
Insufficient precision of traditional cutting methods, resulting in low material preparation efficiency.
Large heat-affected zones from flame/plasma welding. Requires extensive secondary processing (grinding/trimming). Large assembly tolerances for structural components.
03
Difficulty in processing thick plates and high-strength steel.
Heavy structural components and difficult-to-control thermal deformation. Narrow welding windows for high-strength steel and alloy steel. Stringent structural life assessment and fatigue standards..
04
Insufficient flexible manufacturing capabilities due to multiple models and batches of orders.
High customization rate of large structural components. Frequent model changes lead to low start-up efficiency. Dispersed equipment utilization.
05
High rework costs,Limited production stability.
The current production model relies heavily on experienced workers, making processes difficult to standardize and replicate; new employees require long training periods and ramp-up time, limiting overall productivity expansion.
06
Enhanced environmental protection and safety
Environmental protection will serve as a core value to attract more outstanding cooperative projects.
