Prototek – Metal Prototyping Made Simple
Our metal prototyping services involve creating a model of a product in order to ensure correct measurements and functionality of the part designed. Our customers use prototypes to evaluate and update parts before mass production begins. Our metal prototyping services get used frequently across a wide range of industries. You can find metal components in automotive, aviation, construction, medical, aerospace, technical design and other sectors due to the extreme advantages of metal components when engineering. So, if you’re looking for a company to handle your metal prototyping, contact Prototek.
What is Metal Prototyping?
In case you are new to the process, a prototype is a mock-up or preliminary draft of a part intended for eventual mass production. Long before production begins, prototypes get developed to allow designers to examine and modify the component.
In metal prototyping and metal prototype fabrication, prototypes get created from various materials, depending on the manufacturing process. One of the most efficient and extensively used in metal prototype fabrication is sheet metal, but other metals can be leveraged in metal prototyping. You can build a prototype out of aluminum, steel, or other materials, but be sure to contact us to get a sense of what metals can be used for your specific metal prototyping needs.

Metal Prototype Design Considerations
In general, metal prototype fabrication refers to manipulating materials to manufacture a piece of metal for a final product. It entails the cutting, shaping and finishing of the select metal. Metal prototyping is a common procedure through many industries, including medical devices, computers, electronics and appliances. However, regardless of the industry or end product, there are several design considerations that need to be considered for any metal prototyping project. Here is a list of the design elements to keep in mind:
-
Bends
Bending is used to form a material to a specific shape or shapes through the application of force. It is one of the most common sheet metal design methods and may also be called press braking, flanging, die bending, folding or edging.
-
Wall Thickness
The thickness of the sheet metal will affect how it should be handled and the force needed to apply design methods.
-
Bend Relief
An incision cut along the sides of a proposed bend in sheet metal to prevent tearing and part deformation during the bending process. Bend relief lengths and widths vary between projects and depending on the metal used.
-
Slots and Holes
Holes and slots must be at least as wide in diameter as the material is thick. It’s also important to consider distance from the edge.
-
Tabs and Notches
Tabs and notches also come with distinct requirements for effective metal fabrication. Notches must be at least the thickness of the material or 0.04 in. (1.016mm), whichever is greater, and no more than 5 times the width of the material. Tabs must be at least 2 times the thickness of the material or 0.126 in. (3.200mm), whichever is greater, and no more than 5 times the width.
-
Hems
Hemming is a metalworking technique that involves rolling the edge of sheet metal over and onto itself, forming a two-layer field. There are two types of hems, open and closed. The tolerance of a hem is dependent upon the hem’s radius, material thickness and features near the hem.
-
Countersinks
Conical holes are cut into a manufactured item to allow a screw, nail or bolt to be inserted flush with the surface.
-
Offsets
Offsets are used to create Z-shaped profiles in sheet metal parts.
Metal prototyping is beneficial to ensure the safety and strength of the materials when used in a particular project. Moreover, getting the exact measurements are of great help, whether in rapid metal prototyping or custom metal prototyping, to ensure the fit, strength and lifespan of the end product.
