Buff Polishing

Polishing and buffing are two different processes although they may sound similar. Both the processes enable a smooth finishing to the surfaces of a part or product. Plastic polishing encompasses lending optical clarity and transparency to the plastic object. This not only improves the aesthetics but also the object’s physical properties. In buffing, an abrasive material is used which superficially cleans and evens out uneven parts on a surface, and helps remove minor dents and scratches. Ehren Haus offers various plastic polishing methods such as flame, buff, and hand polishing.

Our Buff Polishing Capabilities

We perform buff polishing with the help of a buff wheel. It can be done on almost all types of plastics. Here are our capabilities.

Types of Plastics

We offer buff polishing for several plastics such as acrylic, polycarbonate, polyethylene, PVC, nylon, HDPE, composite plastics, and even alloys. We accept your designs. Send your files in CAD, IGS, or DXF formats.

Electropolishing

In this method, a chemical electrolyte and current are together used to refine the finishing of a part or product. It removes surface flaws and mitigates the induced stress.

Buffing Compounds

We use good quality buffing compounds and in appropriate quantities. We typically use this process after machining your part to give it the required finish.

Buff Methods

To achieve the right finish, we use two buffing methods- cut motion and color motion. Cut motion helps achieve a uniform finish which is low to medium bright. In this method, the workpiece is moved in the opposite direction of the wheel. In the color motion method, medium pressure is applied which enables a glossy or shiny finish to the workpiece surface.

Value Added Services

Apart from polishing, we offer coating and engraving services as well. Our buff polished edges are soft and have a clean cut. Along with buff polishing, we use sand polishing and a hydrogen/oxygen flame for the edges. The finishing or the level of shine depends upon your application requirements. We offer a mirror-like shine, lustrous shine, matte finish, or a satin or glossy finish.

Abrasive Flow Machining

In this process, we pass an abrasive grain mixture through the internal openings in the part. It enables us to shape and polish the part well without disturbing the geometry. We begin with low-grit abrasives and proceed towards the high-grit ones. We ensure to select the right abrasive which prevents further damage to the part surface. In gritting, the abrasive used is just loosely tied to the buff wheel and not fitted. This makes it easy for us to remove or replace the abrasive when required.
