# Fusion Plating — Chrome Plating Process Pack
|
|
|
|
Part of the **Fusion Plating** product family by Nexa Systems Inc.
|
|
|
|
Data-only add-on for the `fusion_plating` core module. Seeds chrome-plating
|
|
process types and their bath chemistry parameter schemas.
|
|
|
|
## What it ships
|
|
|
|
### Process types
|
|
| Code | Name | Chemistry |
|
|
|---|---|---|
|
|
| `CR_HARD_HEX` | Hard Chrome — Hexavalent (Cr(VI)) | Cr(VI) |
|
|
| `CR_DEC_HEX` | Decorative Chrome — Hexavalent (Cr(VI)) | Cr(VI) |
|
|
| `CR_HARD_TRI` | Hard Chrome — Trivalent (Cr(III)) | Cr(III) |
|
|
| `CR_DEC_TRI` | Decorative Chrome — Trivalent (Cr(III)) | Cr(III) |
|
|
| `CR_STRIKE` | Chrome Strike | Cr(VI) |
|
|
|
|
Hex-chrome variants are colour-tagged red, trivalent variants green, and
|
|
the strike grey. All five live under the core's **Plating** category.
|
|
|
|
### Bath parameters
|
|
CrO3, trivalent Cr, H2SO4, CrO3:H2SO4 ratio, bath temperature, current
|
|
density, iron/copper contamination, mist suppressant level, and voltage.
|
|
|
|
## Hazard awareness
|
|
|
|
Hexavalent chromium is a **confirmed human carcinogen** (IARC Group 1,
|
|
NTP Known Human Carcinogen, Ontario Reg. 833 designated substance). The
|
|
`hazard_notes` field on every hex-chrome record flags:
|
|
|
|
- Ontario Reg. 833 ceiling limit 0.05 mg/m³ as Cr(VI)
|
|
- Mandatory mist suppression and medical surveillance
|
|
- Toronto Ch. 681 sewer limits (Cr(VI) 2 mg/L, total Cr 4 mg/L)
|
|
- NPRI Part 1B reporting, CEPA Schedule 1 listing
|
|
- No storm sewer discharge (storm limit 0.0008 mg/L Cr(VI))
|
|
- Industry transition toward trivalent chrome where part specs allow
|
|
|
|
Trivalent variants carry a lighter hazard note but still fall under the
|
|
Toronto total-chromium discharge limits.
|
|
|
|
## Install
|
|
|
|
Requires: `fusion_plating` (core).
|
|
|
|
```bash
|
|
docker exec odoo-dev-app odoo -d fusion-dev -i fusion_plating_process_chrome --stop-after-init
|
|
```
|
|
|
|
All records load with `noupdate="1"`, so shop overrides survive upgrades.
