How to Prevent UHMWPE Mining Chute Liner Warping

Overview

This guide covers the practical steps to prevent uhmwpe mining chute liner warping. JSLT Mining 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. Counter-bore correctly. Use 1.5× bolt-head diameter to allow thermal movement.
2. Avoid over-tightening. Torque to 60% of yield; over-torque causes warp.
3. Limit panel size. Panels > 1500 × 3000 mm risk warping; subdivide if needed.
4. Allow expansion gaps. 3 mm gap between panels per meter of length.
5. Inspect early. Re-torque at 100 hours to catch any settled bolts.
