Metal fabrication includes cutting, welding, forming and machining sheets of metal, but the process doesn’t end there. Finishing operations, as the name implies, are the final step of fabrication and are vital to turning out a quality product. Rust and corrosion control, protection against heat/environmental damage and enhanced, branded aesthetics are all elements of metal fabrication finishing services.
Badger Sheet Metal Works’ (BSMW) industrial finishing experts have spent decades refining the treatment and painting of metal. With an extensive range of in-house finishing capabilities and reliable partners available, BSMW can handle the needs of any project. The following are all options available for your next project:
The process of removing the rough edges of a part is called deburring. When metal is cut or punched, the thin, sharp burrs created can be a potential safety risk or damage the integrity of finished components if not removed.
For example, if flakes of metal contaminate food, they pose a serious health risk. Parts used in critical assemblies, like industrial machines, can also create a hazard if components are defective.
BSMW eliminates this risk by using an ARKU 3000 deburring machine to give components a smooth, uniform texture. The ARKU deburrs the inner and outer profiles and the top and bottom surfaces of a part in a single pass, processing material up to 51-inches wide and any length.
Deburring produces a consistent finish, making a better adherent for paint and a much safer product to handle.
Parts made at BSMW for food packaging, bottling and water filtration are often run through the deburring process.
A part is polished after it is engineered, cut, formed and deburred.
An abrasive compound is applied using a belt, polishing any remaining microscopic burrs and buffing a part to a final finish. BSMW’s LYNX Timesaver can polish plate sheet to any grain finish desired. In one pass, the machine performs a three-step process with two sanding drums, a Scotch-Brite™ drum and a water filtration system that keeps the parts cool.
BSMW’s LYNX Timesaver is located in the shop’s stainless steel room, a clean environment that meets the stringent 3-A Sanitary Standards required by the food, dairy and pharmaceutical industries.
Parts specific to the bottling, architectural and packaging industries typically require polishing.
BSMW’s wet paint area, located at the end of the shop, is a project’s final stop before shipment.
A paint finish is a critical step in the sheet metal fabrication process, extending the service life of a part and enhancing its appearance.
Painting is a cost-effective alternative to finishing options like powder coating and is ideal for parts that cannot be heated or require custom color.
BSMW’s Wet Painting Process
The BSMW team begins the painting process with a clean surface cleared of any debris through a chemical phosphate wash. This pre-treats and de-greases the metal and removes loose particles, scale and oil. Aluminum requires a slightly different preparation, including a soap wash and chemical etching spray for maximum paint adhesion.
A rust-inhibiting primer is then applied, improving paint adhesion by sealing the porous surface of the metal. Several layers of paint are applied after the primer, and the part is finished with a protective coating. BSMW’s painters also perform a weekly crosshatch adhesion test to ensure paint won’t chip or flake.
BSMW paints both aluminum and steel and can match a customer’s sample of color, texture or mill thickness.
The curing time can be several days, depending on the paint.
BSMW’s in-house wet painting services:
- Anti-skid coating
- Zinc primer
BSMW Wet Painting booths
BSMW’s two 30 x 20 x 14-foot painting booths and two shifts of painting teams keep parts moving through the production process and prevent project bottlenecks. The spray rooms are enclosed with filtered air, keeping a high level of control over contaminants and allowing coatings to be applied at a very high standard.
A dedicated wash bay is used for material prep, and a 70 x 70-foot dry bay keeps products free of the smudges that can be caused by premature handling. The two painting booths also have baking capabilities.
Conveyor, industrial machine, cabinet, and electrical enclosure components are often painted at BSMW.
BSMW’s engineers and project managers will work with you to determine which paint best accommodates your sheet metal fabrication project and budget.
BSMW also offers zinc plating, electroless nickel, black oxide, cadmium, Teflon and various other finishes and coatings through carefully-vetted third party providers.
“Using the proper equipment to maximize efficiency and designating areas for our painting, stainless steel finishing and deburring processes ensures the customer gets a better price and product,” explained Kenny Coe, BSMW’s director of sales.
Are you invested in your parts?
If safety, performance and longevity are the goal, deburring, polishing and painting should be thought of as an investment instead of an expense.
Finishing operations have been a specialty at BSMW for more than twenty years, with its team taking pride in the workmanship that goes into every project. In addition to metal and surface finishing, BSMW offers a full range of sheet metal fabrication services. Its team can take your design and transform it into a fully-assembled and finished product. The ability to complete your project in house, taking it through each stage of the fabrication process, reduces production costs and keeps quality consistently high.
