While most extruders don’t require packaging specifications. If you pick your own packaging, you have the most control ensuring perfect parts at your door. For just-in-time manufacturing, sometimes you can’t afford to have losses due to shipment damage so it’s better to pay more for packaging than to put a sale on backorder and risk losing the sale.

Extrusion Packaging

Thursday, July 15th, 2010

- Cut length
- Alloy
- Finish
- Flatness
- Straightness
- Twist
- Surface defect tolerances
- Packaging
