Services
The manufacturing of mining machinery is a complex process that encompasses design, material processing, assembly, and testing. Below is a comprehensive introduction to the entire manufacturing process, integrating key technologies such as sheet metal processing, welding, and machining:
1. Requirement Analysis and Design Phase
2. Raw Material Preparation and Pre-treatment
3. Core Manufacturing Process
Sheet Metal Manufacturing: Material cutting → Forming → Joining
Heavy Structural Welding: Welding process selection (welding method); Quality control (pre-welding and post-welding preparations).
Machining: Machine tool processing (turning and milling); Special processes (heat treatment and surface hardening).
Assembly and Final Assembly: Sub-assembly; Final assembly and debugging.
Surface Treatment and Coating
Quality Inspection and Testing
Sharp Century offers robust sheet metal fabrication capabilities to produce components that meet strict quality and performance standards.

Common Issues and Solutions in Mining Equipment Fabrication:
Excessive burrs on material cutting edges
Optimize cutting parameters (reduce laser power, increase cutting speed).
Cracking or excessive springback after sheet metal bending
Adjust the bending radius (typically ≥1.5 times the sheet thickness); Orient the bending direction perpendicular to the material grain direction (avoid bending along the rolling direction); Implement bending compensation.
Welding distortion causing assembly misalignment
Use segmented welding to reduce localized heat accumulation; Employ welding fixtures to secure the workpiece; Perform mechanical straightening after welding.
Coating peeling or bubbling after painting
Perform sandblasting before painting; Control the painting environment; Use epoxy zinc-rich primer to enhance adhesion.
Excessive flatness deviation in large sheet metal components
Apply vibration stress relief after welding to eliminate residual stresses; Store large flat components vertically to prevent deformation due to self-weight.
