Design Features

  • Flaws in the base material, such as pores, gas inclusions and laminations etc., are generally visible after chromium-plating and require additional rework in our plant
  • The steel should be as fine-grained as possible
  • Castings with a high recycling share may result in problems (pores)
  • Avoid sharp edges (radii)
  • Indentations: depth max. diameter
  • Partial chromium-plating may, under certain circumstances, be more expensive than full chromium-plating (masking work)
  • In the case of full chromium-plating, establish whether everything really does need to be chromium-plated (e.g. small bores)
  • Select the plating thickness in accordance with requirements
  • Avoid unnecessary tolerance specifications

Note

  • Surface roughness is never improved by chromium-plating (without mechanical finishing)
  • Supply the workpiece protected against damage (plastic, wooden crate or acid-free cardboard carton etc.)
  • The workpiece should be lightly oiled (e.g. oiled paper)
  • Never use substances containing silicone
  • Neatly clean after preparation, i.e. there should be no metallic or loose residue or in the material
  • Always enclose a drawing if possible
  • Specify the material precisely and any pretreatment performed (e.g. gas-nitrided or ionitrided etc.)
