Frequently Asked Questions
What questions should I be asking a sheet metal prototyping company?
What is your current capacity?
What is your turn time?
Can you provide an NDA?
Do you quote from a solid model or drawings?
When can I expect my quote?
What materials do you work with?
What are your standard tolerances?
Do you install inserts?
Do you do tig welding?
Do you do any finishing?
Do you provide silk screening and assembly services?
Do you do design work or reverse engineering?
What are your standard radii?
What are some common reasons companies reject sheet metal prototypes?
Length or width issues
Thickness (too thin, too thick)
Material type
Tight tolerances
Special tooling or forming that requires tools or skills
The company does not have certifications to meet the requirements of the part
Machine limitations
What makes Prototek different is our ability to handle the most complex jobs – having the capability to quote most any prototyping project across processes and finishes.
How fast can Prototek respond to a quote?
In most cases, we will get back to you within 24 hrs. If all information required is not provided, we will contact you. If you require a quote much faster, please contact us and speak to one of our skilled team members.
What types of metals can be used for sheet metal forming?
Cold rolled steel, hot rolled steel, aluminum, stainless, copper, brass, beryllium, titanium, galvanized
What are common sheet metal material thickness ranges?
.005, .006, .010, .017, .020, .023, .025, .030, .032, .036, .040, .042, .048, .050, .059, .060, .063, .074, .075, .080, .090, .100, .104, .105, .134, .135, .160, .179, .188, .190, .239, .250, .312, .375, .437, .500, .625
What are minimum and maximum dimensions in inches?
We will discuss your dimension needs directly with you.
What are tolerances?
Tolerance is a limit or limits of a physical dimension, measured value, or physical property of a material or manufactured object.
What is air bending vs coining?
Air bending is a method where the material is forced into a V-die opening requiring less bend force and tonnage. You can use smaller tooling and the angle of the tool is less important. Air bending requires a little more attention as the angles will not be as consistent and require forming to a more acute angle due to spring back.
Prototek uses a press brake tool for air bending, coining, and bottoming. We can also work with designs needing three-point bending, folding, wiping, rotary bending, roll bending, elastomer bending and joggle bending.
Coining involves using enough tonnage to conform the material to the exact angle of the punch and die. Coining is used more in production where a lot of parts will be manufactured and need to hold exact tolerances and precise angle of your tooling.
What is plating?
Plating provides many benefits to products made from metal and other materials. Plating is a manufacturing process in which a thin layer of metal coats a substrate. This can be achieved through electroplating which requires an electric current or through electroless plating which is in an autocatalytic chemical process.
What is stitch welding?
Stitch welding or intermittent welding involves initiating a weld, typically indicated on a drawing, terminating the weld, and then starting again along with the joint a specified distance from the previous weld. Stitch welding can be used when air or liquid tightness (Seal) is not a requirement when structural integrity is not a concern or to control heat.
What is Prototek’s finishing process?
Prototek utilizes a multi-step process of anodizing & finishing which includes cleaning, treatment, anodizing, coloring, sealing, and numerous quality rinses in between each phase. We focus on controlling the pH, temperature, concentration, frequency, and duration. Our technicians maintain multiple controls in the tank to ensure a consistent, quality coating. As industrial craftsmen, these processes and quality phases are the art and science we take pride in delivering high-quality parts to our partners.
Prototek offers:
Powder-coating
Painting
Silk-screening
Laser engraving
Chem-film
Anodizing
Bead blasting
Tumbling
What is the range of part thickness Prototek works with?
Prototek can manufacture sheet metal parts ranging in thickness from .0.010 inches to .25 inches.
