Conveyor faces
State thickness, the product that slides, and whether the factory is quoting a blank or a nest.
uhmw pe
Translate a uhmw pe project into purchase requirements, not into a promised wear result. Density in g/cc is only a grade split if the drawing uses it that way.
Site conditions that change the requirement
Chute and hopper liners
Medium and outdoor exposure change the brief. UV-stabilized is a written ask.
Machined wear pads
Cut-to-size needs L × W and any hole pattern. Color is not a machining proof.
Food-adjacent surfaces
A food-contact file must name the grade and lot. A plant letter is not enough.
Assumptions that must be confirmed in writing
Commodity HDPE sheet and this UHMW family are not interchangeable because a chute is abrasive. If density in g/cc is how the buyer distinguishes grade, write the figure the factory must confirm. This desk does not publish a density for any option.
| Buyer assumption | What the factory must confirm | What this desk will not claim |
|---|---|---|
| uhmw pe equals any polyethylene sheet | Resin family, thickness and finish for the quoted line | A wear-life or friction result |
| Density in g/cc is optional decoration | Whether density is the buyer’s grade split | A published density for any option |
| Black sheet is automatically UV-stable | Whether a UV package is on the quoted resin | A silent outdoor rating |
| A food-contact plant file covers the lot | File names the grade and lot | A site-level FDA badge |
