Telescopic Handle Manufacturing: Extrusion and Assembly Guide
Handle Components and Materials
Telescopic handle manufacturing uses aluminum 6061 tubes for lightweight strength. Button housings are zinc die cast, locking pins precision machined from stainless steel. Tube diameter 16-25mm with 0.8-1.5mm wall thickness.
Anodized finish provides scratch resistance. Clearance 0.1-0.2mm for smooth telescoping.
| Component | Material | Process | Finish |
|---|---|---|---|
| Outer Tube | 6061 Al | Extrusion+CNC | Anodizing |
| Inner Tube | 6061 Al | Extrusion+CNC | Anodizing |
| Button | Zinc alloy | Die casting | Chrome |
| Lock Pin | SS 304 | Swiss CNC | Passivation |
Assembly and Testing
Push-button mechanism assembly with spring tension adjustment. Cycle test: 10,000+ operations. Pull force: >500N. Button force: 5-15N. Tube straightness within 0.5mm/m for smooth operation.
Visual inspection for surface defects, dimensional verification of extended and retracted lengths.
