Press Dies Need Care Too
Crystal press dies are precision tools that degrade with abuse. Here is how to maintain them.
What Damages Dies
| Cause | Damage |
|---|---|
| Metal-on-metal contact without cloth | Scratches on contact faces transfer to crystals |
| Pressing at angles | Dies develop uneven wear — future presses go crooked |
| Rust storage | Pitted faces mark crystal surfaces permanently |
Maintenance Routine
- Wipe after every use: removes compound residue and moisture
- Light oil film before storage — prevents rust in humid climates
- Inspect contact faces: hold under light at an angle; any visible scratches mean the die will mark your next crystal
- Sand lightly if scratched: fine grit (1500+) wet sanding restores flatness on steel dies
When to Replace
Deep pitting or bent die walls cannot be repaired economically — replacement die sets cost less than one ruined sapphire crystal.

Frequently Asked Questions
Plastic dies need oil too?
No — plastic dies just need cleaning and scratch inspection. Oil attracts dust on plastic surfaces.
