Cupro Hard Powder (001)

Additive values of consumption for hard sulphate copper plating bath.

Additive Values & Control Guidelines

The consumption values are dynamic and depend on the chosen hardness. For standard operations aiming for a hardness of 175 - 230 Vickers, the following values apply:
Operating ParameterSpecification Value / Standard
Bolster Up Additive200 - 250 ml per 1000 AH (Ampere Hours)
Preparation Rule40 g dry powder mix in 10 Litres DM (De-mineralized) water
Bath Operating Temp25°C to 40°C
Current Density20 - 40 Amp/dm²

Operational Note: Operational Note: Consumption values fluctuate based on the specific bath temperature and cylinder immersion levels. Regular, continuous dosing is highly recommended.

NF Micro-Pel (004)

Dry-coat cylinder lubricant engineered to prevent debris collection.

Key Advantages & Application Steps

Engineered formulation to optimize mechanical engraving performance and reduce score marks.

Key Lubricant Advantages

  • Stylus Protection: Dry coating prevents engraving debris from adhering to diamond styluses, shoes, or burr cutters.
  • Non-Flammable: Engineered formula ensures maximum safety during application, transit, and workshop storage.
  • Friction Reducer: Minimizes score marks, allowing the shoe slide to glide smoothly across cylinder copper surfaces.
  • Water Repellent: Provides soil retarding and water repellent finish layers.

Application Steps

  1. Thoroughly clean and dry the rotogravure cylinder surface.
  2. Apply a very thin, even layer of **NF Micro-PEL** to the rotating cylinder using a clean paper towel or soft cloth. Avoid heavy streaks.
  3. Buff off any visible excess lubricant with a clean, dry cloth.
  4. Wipe the cylinder several additional times. This buffs the cylinder to a glassy, dust-free surface ready for diamond engraving.
