How to Specify UHMWPE Infeed Worm Screw Pitch and Length

Overview

This guide covers the practical steps to specify uhmwpe infeed worm screw pitch and length. JSLT Engineering Plastics produces engineering plastic components in UHMWPE, HDPE, PA, POM and PTFE — full-process fabrication from raw sheet to CNC-machined parts.

Step-by-step procedure

1. Identify bottle pitch in star wheel. Bottle pitch = star wheel pocket pitch.
2. Calculate worm length. Worm length = number of bottles × pitch + entry length.
3. Choose flute geometry. Variable-pitch flute accelerates bottles smoothly.
4. Match shaft and bearing config. Specify shaft diameter and bearing block locations.
5. Send DWG for quote. Email DWG to claire@jsltupe.com — quote in 24h.
