Yes you can! Small modular anodizing systems for machine shops are becoming more available and affordable.

The foot print of a system like this is generally under 15-20′ long x 8′ wide.

Is Machine Shop Anodizing Right for My Company?

Determining if anodizing is practical for you is easy if you do your homework and consult a true expert. Why are you considering doing your own anodizing? Are you having problems with outsource costs, availability, delivery or quality? Many times these problems can be solved by working with vendors. Making the decision to anodize in your shop demands that you learn about anodizing and how it will affect your company.

Machine Shop Anodizing, is it Difficult to Learn?

Anodizing is one of easiest finishing processes to learn. If the initial equipment is designed correctly the process itself becomes fairly routine. There are a few proprietary chemicals and process formulas that you will have to learn about. Chemicals are available in most States and Cities. If you are planning on color anodizing (Type 2) you will need to add dye and sealing tanks, so the line length will increase as will the cost of the equipment. As with all metal finishing operations cleaning the parts properly is a must. A series of pre-clean, de-oxidizers and proper rinsing are also essential.

Machine Shop Anodizing – Environmental & Waste Problems?

Anodizing Water Pollution – Anodizing involves chemicals and rinsing.  These processes are regulated by both Federal and State laws.  Typically rinse water can be recycled or sent to the sewer if local regulations are met.  The key to success is waste minimization, good housekeeping and properly designed anodizing equipment.

Anodizing Air pollution – Adequate ventilation is necessary. Most quality systems have ventilation hoods built in. You will need to exhaust the fumes outside of your building. This means you will need a corrosion resistant exhaust fan and ducting. Type 1-A anodizing emits chromic fumes and most government agencies will require a fume scrubber, but Types 2 & 3 may not.
