Photochemical Machining

Chemically Etched Parts: Great Lakes Engineering boasts over 20 years in photo chemical etching and metal etching technology.

In essence, this is the process of printing (photo-plotting) a pattern on a metal foil and immersing it in a precise combination of chemistry in order to eat through (etch the pattern into) the metal.

Many of the same products can be manufactured using different processes. Great Lakes Engineering has the experience to determine which process is appropriate for the application, tolerances, longevity, durability and cost.

Materials:

• Stainless Steel
• Steel Alloys
• Nickel
• Copper
• Copper Alloys
