WHY USE CELCO FOR YOUR ELECTROPOLISHING NEEDS?
Central Electropolishing Co., Inc is a highly regarded company in the field of electropolishing. CELCO has the knowledge, ability and staff to handle any size, shape or quantity of parts.

CELCO is a regulatory control company. Each job has a traveler, which traces the component from arrival to departure.

The first step is INSPECTION. CELCO inspects each part for damage, material compatibility and cleanliness. Every part is cleaned before the Electropolishing process is begun. CELCO has the necessary tooling and equipment to perform the Electropolishing process and the necessary equipment to measure the surface in micro inches/micro meters (RA). The micro inch measurement can be taken to the single digit level. CELCO has automated tooling for small parts, greatly reducing the cost to the customer.

We know that the only bridge between you and our Electropolishing service is an introduction and that can be accomplished by telephone, fax or email. CELCO will be there for you and your company if you only make the connection.


WHO SHOULD BE ELECTROPOLISHING?
When a design requires a metal finish that demands smoothness that cannot be obtained by standard mechanical polishing, electropolishing is the solution. When looking for a method that deburrs, Electropolishing can and does remove burrs during the electropolishing process. A surface can generally be improved to approximately one half the initial surface measurement. Some surfaces can be obtained by electropolishing, become non-particulating surfaces, i.e. so smooth, particles cannot be entrapped and adhere to the metal.

BENEFITS OF CHOOSING ELECTROPOLISHING

• Electropolishing removes iron from the surface of the component.

• Electropolishing enhances the precentage of chromium/nickel on the material surface and promotes a bright, deburred, corrosion resistant, passive surface.

• Electropolishing is the superior form of passivation for stainless steel and other alloys, as much as 3,000% greater than standard passivation, according to some studies.

• Electropolishing removes microscopic burrs as parts are electropolished.

• Electropolishing creates a smoother surface decreasing friction and drag .

• Electropolishing provides an easy economical choice, for large quantities of small parts.

• Electropolishing leaves a beautiful mirror like finish on most components.

• Electropolishing stress relieves the surface of components.

WHAT IS ELECTROPOLISHING?
Electropolishing is defined as the precisely controlled electrolytic removal of metal using an electro-chemical process. The metal component, composed of stainless steel or other alloys, is placed in an electrolyte solution and electric current is passed through the component. In essence it is the reverse of electroplating. During electroplating material is deposited onto the component; Electropolishing mechanically restructures the surface of the metal by expelling electrons from the exposed surface causing a smoothing reaction.

The process of Electropolishing is so refined that removal of material can be controlled within .0001” per surface. The electropolished surface has an enhancement of its micro-inch measurement; Electropolishing descales the surface, removing oxides and impurities and leaves a sterile, bright, passive finish.

HOW ELECTROPOLISHING WORKS:
The component to be Electropolished is connected to the positive or anodic terminal, and the negative or cathodic terminal is connected to the chosen conductor (rectifier). When the component is submerged into the electrolyte solution, a complete electrical circuit is formed. The current applied during this process is direct current (DC). The amount of material removed during the Electropolishing process is dependent on the amount of DC current applied and the amount time the component remains in the process.
