Key features

We eliminate porosity and leakage by aluminum degassing and full pressure test

We ensure accurate mounting fit by CNC machining and batch fixture inspection

We improve pump efficiency by smooth inner flow channel grinding and cleaning

We remove cold shut defects by optimized mold temperature and surface finishing

We control heat treatment deformation with fixture positioning and gradual cooling

Complaint 1: Porosity causes pressure leakage during pump operation Solution: Degas and filter molten aluminum, 100 percent hydrostatic pressure test before shipment

Complaint 2: Dimensional deviation on mounting flange and shaft bore Solution: CNC machine critical surfaces and bores, batch inspection with checking fixture

Complaint 3: Rough inner flow channel reduces pump efficiency Solution: Optimize gating design, smooth inner wall by grinding and shot blasting

Complaint 4: Cold shut and surface defects affect pump appearance and coating Solution: Control mold temperature, remove surface defects by grinding and polishing

Complaint 5: Deformation after heat treatment affects alignment Solution: Use fixture positioning during heat treatment, controlled cooling rate
