Our Electropolishing Process

1

Part Evaluation

Alloy grade, geometry, heat treat condition, and finish specifications assessed by our experts.

2

Cleaning & Prep

Oils, oxides, and machining contaminants removed. Custom racking for optimal current distribution.

3

Electropolishing

Proprietary electrolyte dissolves surface peaks uniformly. A clean, passive oxide layer forms simultaneously.

4

Rinse & Dry

Thorough multi-stage rinse and controlled drying to preserve the electropolished surface quality.

5

QC & Delivery

Inspected per specification, documented, packed and shipped promptly.

Note: If there is a question regarding our capabilities, please email a print for review to sales@ableelectropolishing.com.

What information do you require in order to receive a quotation?

We need a copy of the drawing, service needed, lot and annual quantities, process specification and packaging requirements.

What is your standard lead-time?

Standard delivery is 3 to 5 working days after receipt of order. Next day and same day services are offered at an additional cost. Please contact our sales department for further details.

What is the difference between passivation and electropolishing?

Passivation is a chemical process designed to remove free iron and other contaminants from the part surface. Electropolishing is an electro-chemical process that removes surface metal which improves micro finish, provides deburring and adds to the aesthetics of your part.
