ZHITIAN provides custom measurement and reverse engineering services to reproduce or optimize screw elements for specific extrusion needs.
Whether replacing worn OEM parts or developing new screw profiles, our services ensure perfect fit, high interchangeability, and enhanced process performance.
Custom Screw Element Measurement Process
| Step | Description |
| 1. Sample Collection | Worn screw elements or OEM samples are collected for measurement. |
| 2. 3D Scanning | High-precision 3D scanners capture the complete screw geometry. |
| 3. Dimensional Analysis | Software analyzes pitch, flight depth, helix angle, and diameter tolerances. |
| 4. Material Assessment | Material grade and hardness are measured to ensure compatibility. |
| 5. CAD Model Generation | A detailed CAD model is produced for manufacturing. |
| 6. Validation & Simulation | Material flow and torque performance are simulated to verify design. |
| 7. CNC Machining & Prototype | Sample elements are machined and tested under actual extrusion conditions. |
| 8. Quality Inspection | Dimensional, hardness, and surface finish inspections are conducted. |
