Common Sheet Metal Applications
Sheet metal prototyping services cases
Material selection
Common sheet metal materials include carbon steel, stainless steel sheets，aluminum, bronze vs brass, bronze, titanium and galvanized steel, galvanized aluminum nickel alloy, Inconel 625i, etc.
The type and thickness of the material directly affect the processing method and the performance of the final product.
Aluminum and Copper
Aluminum 1100-H14: 1100 series aluminum is one of the purest aluminum series, with good electrical and thermal conductivity, but relatively low strength. H14 means hardened to a certain hardness after cold working. Commonly used for deep drawing processing and decorative applications.

Stainless steel and cold rolled steel Hot rolled steel
Stainless steel: such as 304, 316, etc., have good corrosion resistance and are often used in food processing equipment, medical equipment and chemical equipment.

Diversity of surface treatment
Sheet metal parts can undergo a variety of surface treatments, such as spraying, sandblasting, grinding, pickling, phosphating, electroplating (galvanizing, aluminum plating, tin plating, nickel plating, chrome metal plating), spraying, painting, anodizing, etc., which can improve the corrosion resistance and wear resistance of the product, while improving the appearance texture.

 |
Sand Blasting | Sandblasting is the process of using abrasive particles ejected at high pressure and at high speed to remove the oxide layer, rust or old coating on the surface, making the rough surface smooth and improving the adhesion of subsequent coatings. |
|
 |
Powder Coating | Powder Coating is an electrostatic spraying technology that charges the powder coating and adsorbs it on the surface of the object. After high-temperature baking, the powder melts and fixes on the object. |
|
 |
Electroplating | Electroplating is a process that uses the principle of electrolysis to plate a thin layer of other metals or alloys on the metal surface, such as nickel, chromium (chroming), zinc (Galvanizing), silver, rose gold, etc. |
|
 |
Bead blasting | Bead blasting is a surface treatment process, a type of sandblasting. It uses high pressure to propel small beads (usually spherical particles made of glass, ceramic or metal) against the surface of a material to clean or change its surface texture. |

Sheet Metal Processing Design Wizard
The design phase needs to consider the functionality, aesthetics, and manufacturing feasibility of the product.
Material Selection
Choose the appropriate material thickness. The material thickness for sheet metal processing usually ranges from 0.1mm to 12mm. Consider the strength, hardness, ductility, and surface treatment requirements of the material.
Part Size
Make sure the designed part size is suitable for the capabilities of the sheet metal processing equipment. Consider the inner fillet radius and minimum bend radius of the material.
Bending and Folding
The bending radius should be at least twice the material thickness to avoid cracks. The folding angle is usually between 90° and 180°, avoiding sharp bends. Consider the minimum and maximum size limits of the folding.
Precision and tolerance
Determine the appropriate machining precision and tolerance based on application requirements. Avoid overly strict tolerance requirements, which may increase costs.
Hole and Slot:
The distance from the hole to the edge should be at least twice the hole diameter to avoid material tearing. The width of the slot should consider the tool size of the processing equipment.
Connection and Assembly
Design structures that are easy to assemble and disassemble, such as using welding, riveting, or metal fasteners. Consider the fit clearance between parts.
Sheet Metal FAQ
Sheet metal processing is a process that involves processing thin metal sheets into specific shapes and sizes through cutting, forming, folding, welding and assembly. The following are some common problems and solutions in sheet metal processing
What should I do if the material may rebound due to elastic recovery after bending?
The squareness deviation caused by rebound can be reduced by two-stage bending, tapping, cutting V-grooves or adding reinforcement ribs.
When bending the plate after opening a hole, if the hole is close to the root of the bend, the hole may be deformed when bending the plate. How to solve it?
Ensure that there is enough distance between the hole and the root of the bend, or open the hole after bending the plate to avoid deformation.
When processing threaded holes on thin plates, it may not be possible to ensure the effective depth of the threaded hole. How to deal with it?
For thin plates, inner edge flanging can be used to ensure the effective depth of the thread hole.
Are you looking for a metal fabrication company near me that specializes in sheet metal fabrication services?
We are a metal and plastic manufacturing shop located in Dongguan, a renowned manufacturing city in China. Although we may not be geographically close to you, we can offer quick turnaround, with sheet metal parts in just 3 days, and delivery to you via internaton express in 3-4 days.
Do I need laser cutting, water jet cutting or plasma cutting?
The choice of laser cutting, water jet cutting or plasma cutting depends mainly on your specific needs, including the type of material to be cut, the thickness of the material, the cutting accuracy requirements, cost-effectiveness, and sensitivity to heat effects. Laser cutting has high precision and high speed, and is suitable for fine cutting of thin metal and non-metallic materials, but not for cutting thick metal and non-conductive materials. Water jet cutting is a cold cutting process with no heat-affected zone. It is suitable for high-precision cutting of various materials including thick metal, composite materials and brittle materials, but the cutting speed is relatively slow. The high cutting speed of plasma cutting is suitable for cutting medium and thick metals. It is cost-effective, but it may produce heat-affected zones and large cutting gaps. We know which projects require which equipment, so you don't need to specify a specific cutting machine or discuss it with us.
Is it more expensive to use multiple sheet metal forming processes?
Using multiple sheet metal forming processes may increase costs, but these costs can be effectively managed through reasonable process selection and cost control measures. Usually, the cost of parts cut, bent and stamped is higher than that of parts cut only with laser cutting machines. However, most sheet metal parts require a combination of multiple forming processes, which is inevitable.
Is there a minimum order quantity?
We do not have a minimum order quantity. You can order a one-off prototype or over 1,000 units.
