Washing Systems Engineered for Metal Surface Preparation & FInishing

When it comes to metal preparation washers, not all parts washers are created equal. When you want the best possible results from a metal preparation parts washer—one that will produce consistent results and keep your employees safe—you need Better Engineering’s industrial metal preparation parts washer. 

Metal Preparation & Surface Finishing

Industrial metal preparation and surface finishing are metal finishing processes used in aerospace, automotive, general manufacturing, appliances, medical devices, and semiconductor. Surface finishing is commonly used to alter a part’s property to improve appearance, strength, corrosion resistance, or other application-dependent characteristics. Industrial parts washers for metal preparation and surface finishing are utilized upstream or downstream from mechanical processes like painting, passivation, peening, abrasive blasting, grinding and polishing. 

Metal Surface Preparation

Ensuring that metal parts are properly cleaned before painting or surface coating can improve paint adhesion and corrosion resistance. The most critical element of a phosphating washer is the ability to remove oils and grease from upstream processes like grinding or welding. Better Engineering industrial parts cleaning systems are designed to sequence through various stages such as wash/phosphate, rinse, seal, and dry, or any combination of the abovementioned stages. The industrial wash systems most commonly used before painting are turntable washers, conveyor washers, and monorail washers. 

The passivation process uses citric or nitric acid to remove iron compounds from the surface of stainless steel, giving stainless steel corrosion-resistant properties. Better Engineering is the leading manufacturer of automated passivation equipment and agitated immersion passivation systems for industries like a medical devices, aerospace, and space. The industrial parts washers most frequently used for the passivation process are turntable washers, conveyor washers, and monorail washers.

Abrasive blasting is a metal finishing process in which different media types are used to shape, smooth, or clean a part’s surface. These metal finishing systems leave remnants of media after the abrasive blasting process. BE manufactures a wide array of industrial parts washers to remove all media types, so your parts are ready to move on to the following process.
