Sheet Metal Manufacturing Process?

Sheet metal processing is the process of cold processing metal sheets to obtain the needed parts with the same thickness. Shearing, bending, riveting, welding, splicing molding, and other processes are all part of the whole process. To acquire the desired shape and size, the sheet material is bent by hand or die stamping, and complex pieces are created through further welding and machining. Because the entire process is complex, it is vital to pay close attention to the details in order to maintain process uniformity.

What are the uses of sheet metal processing?

Sheet metal is a kind of steel product processing technology belonging to the cold working process, which belongs to the steel processing industry. According to the international definition of sheet metal, sheet metal is a relatively complete cold working process for metal sheets. Board, splicing and other processes are finally formed.

The main uses of sheet metal processing products: sheet metal processing applications have universal uses. Sheet metal processing is used to manufacture precision parts for electronic appliances, assist in the field of communications, and produce car shells and bodies for automobile manufacturing processes. It is also used in the manufacture of medical devices. In short, sheet metal processing has a very wide range of uses, which brings a lot of convenience to our production and life.

Reasons for choosing us?

The main processes of sheet metal processing include cutting and blanking, CNC bending, punching and shearing, stamping, rounding, riveting, welding and other methods. It can also be said to be the working principle and operation method of various equipment. All sheet metal processing processes are based on careful design and specification of product drawings by sheet metal engineers before operation. The main process terms are: blanking, riveting, bending, cutting, blanking, punching, riveting, pulling mother, pulling riveting, riveting, chamfering, forming, punching convex hull, punching and tearing, punching, expanding Hole, punching, chamfering, back thread, drawing hole, tapping, leveling, drilling, countersinking, leveling, welding, spraying, assembling, etc.

What are the process characteristics of sheet metal processing?

Sheet metal is thinner than steel, so it is lighter in mass. Sheet metal processing adopts cold working technology, so it has a relatively large strength and is very hard. In addition, sheet metal and steel can pass current and have good electrical conductivity. And in terms of price, it has a good cost performance compared to other steel processing methods.

Why is laser cutting recommended as the way to cut sheet metal?

1.High precision:

The laser cutting incision is narrow and the section is more smooth. There is no burr which is often seen around fillets and mechanical feeding openings.And the cutting deformation is small.

2.Fast speed:

The power of fiber optic device affects the cutting speed. Increasing the power of fiber optic device can increase the cutting speed.

3.High Efficiency:

Laser cutting is non-contact processing. There is no mechanical blanking impact, so it will not produce cutting tool wear phenomenon. Cutting is one-time processing, there is no follow-up work.

4.High flexibility:

Combined with CAD technology, we can cut plates of any shape and size without cutting tools and abrasives, which is suitable for complex parts especially.

5.Free from various hardness of materials:

Steel plate, stainless steel, aluminum alloy plate, hard alloy, no matter what kind of hardness, can be laser cut without deformation.

6.Manufacturing standards for sheet cutting:

1.Thickness tolerances are independent of cutting tolerances, as they rely on the raw stock material's tolerance range.
2.Edge to edge tolerances is +/- 0.005” nominal on the top face of the plate/sheet.
3.Some cut materials may show a small halo discoloration from backsplash or overspray near the cut edges.

7.Sheet metal manufacturing standard:

1.Forming and bending: +/- 0.020"
2.Bend to hole or feature: +/- 0.010"
3.Linear dimensions excluding locations to bends: +/- 0.005"
4.Angularity: +/- 2 degrees
5.Surface roughness (blank material): Ra 125 uin max
6.Sharp edges will be broken and deburred by default. Critical edges that must be left sharp should be noted and specified on a print.

FAQs on sheet metal processing :

What files can MIC-ZG use for laser cutting?

MIC-ZG can accept DXF, STEP, STP, SLDPRT, IPT, and SAT files for laser cutting services. These files should be flat profiles extruded to the appropriate thickness or gauge of the intended material.

What is the Maximum Part Size MIC-ZG can Cut?

MIC-ZG has access to platforms up to 10' x 30' for laser cutting and waterjet cutting. However, many sheet stock sizes commonly cap out at 48” x 96” (4' x 8') or smaller. Additional lead time may be required for larger format cuts due to material sourcing and shipping.

What is the Smallest Part Size MIC-ZG can Cut?

MIC-ZG can cut features down to about 0.25” x 0.25” depending on complexity. Parts below the size of a nickel may require specialized workholding. It is recommended that parts under 2” x 2” may need to be tabbed to a sheet or bridged on as a strip to prevent falling between machine slats. Holes and cutouts should be larger than the material thickness or 0.050”, whichever is greater.

Can MIC-ZG Cut Both Outside and Inside Features?

Yes! Sheet cutting, such as laser cutting services, can cut the outline of a part and any top-down through features such as holes, design patterns, grate features, etc. These features should be provided all in one file.
Sheet cutting cannot do partial-depth features like blind bosses, counterbores, undercuts, or side holes. This would require CNC machining services.

What is Kerf?

Kerf refers to the material that is burnt or cut away during laser cutting. Kerf is the gap thickness created by the laser and is usually around 0.008” with a +/- 0.004” tolerance depending on the process and material thickness.
MIC-ZG's typical part tolerance is +/- 0.005” for laser cutting cutting; this includes compensation for kerf. Small holes, thin gaps, and relief cuts may be slightly larger than dimensioned if their design is close to the kerf thickness.

What is the Material Grain?

Extruded materials such as metals and some plastics will have a grain direction. This is presented by linear features which are generated as the material is created. Hardwood and wood veneer will also have a grain direction based on the growth.
Parts are weaker or may crack more easily along their grain. If grain direction is important to a part's function or cosmetics, please identify that using an attached technical drawing or notes. Otherwise, MIC-ZG's suppliers will use their best practices when cutting the parts.

What do Edges Look Like after Sheet Cutting?

Laser beams have a slight cone shape and will show a small taper from the top cut to the bottom face of a material. This is more exaggerated over thicker parts.
Laser cutting will be vertical striations on a cut surface. This is different from a CNC milled or CNC routed edge which will appear smoother.
By default, part edges are deburred but there may be a small visible bump or notch on the external edges as well as internal cuts where the laser beam initiated the cut of that feature.
