Professional Benchtop Black Oxide 

Mini Finishing Systems

Bringing your metal finishing in-house shouldn't mean compromising on safety or quality. The Tru Temp process is the industry standard for reliable, high-performance black oxide that fits right into your tool room or prototyping shop. Stop waiting 5–10 days for outside vendors to return your parts. With a Tru Temp kit, you can go from raw steel to a finished, black and corrosion-resistant part in under an hour.

Birchwood Technologies’ Mini Black Oxide Systems are ideal for testing or small scale production. DIY industrial blackening system enable same day finishing of small production parts. Pilot the Birchwood system and easily scale into our BT40 or BT100 full production systems.

The systems available include:

1. Tru Temp 2nd Gen - Mid-Temperature black for iron and steel
2. Tru Temp Stainless - Mid-Temperature black for stainless alloys

Traditional black oxide requires a dangerous 285-295F operating temperature. Birchwood's patented Tru Temp operates at just 200-210F , significantly reducing the risk of boil-overs and caustic fumes while lowering energy costs.

Includes enough chemistry to fill system twice plus replenishment, tanks, heaters, thermometers, and a process basket—no hidden extras needed.
