Sheet metal mean is a synthetical cold working technology,Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate.It includes shearing, punching / cutting / compounding, folding, riveting, splicing, forming (such as car body) etc.Its remarkable feature is the same thickness of the same parts.


Sheet metal has the advantages of light-weight, high strength and electric conduction (can be used for electromagnetic shielding), low cost, mass production with good performance, widely used in electronics, communications, automotive, medical equipment and other industry, such as computer chassis, mobile phone, MP3, sheet metal is an indispensable part.


With more and more extensive application of sheet metal, sheet metal design has become a very important part in the process of product development, mechanical engineers must master the design techniques of metal parts, makes the design of sheet metal products not only satisfy the function and appearance requirements, but also can make the stamping die has simple manufacture and low cost.

Material behavior

Material size

stainless steel plate

SUS,STAINLESS STEEL

SUS304(18-8 stainless,nonmagnetic)

SUS301(Spring stainless steel, slightly magnetic)

SUS430(It's magnetic, it's easy to rust)


1, white metallic luster, the surface is not easy to rust, according to the surface state can be divided into: fog surface, bright surface, mirror surface, drawing surface etc. it is need to use PVC  to protect the surface


2, generally do not do surface process. Paint must be treated with special surface.

1, material thickness general tolerance + 0 - 0.08, e.g. the plate thickness 2.0mm, measured may be only 1.92mm.


2. Measuring material thickness shall be used micrometer . Do not use vernier caliper


Cold rolling steel

SPCC,CRS

/

1, iron gray luster, the surface is easy to scratch and rust, processing should pay attention to protection and quickly turn sequence.


2, suitable for electroplating (zinc plating-colorful , zinc plating-white,nickeling,tinning...) baking varnish and powder coating... Other workpiece


1, material thickness general tolerance + 0 - 0.08, e.g. the plate thickness 2.0mm, measured may be only 1.92mm.


2. Measuring material thickness shall be used micrometer . Do not use vernier caliper


3. After processed will be daub anti-rust oil or cover with tarpaulin to prevent workpiece rust.

A1050P,A5052H32P,AL6061T6,AL6063T5…

1.white metallic luster, the surface is easy to oxidation corrosion, it is need to use PVC  to protect the surface.


2.Surface treatment: sand blasting, brushing, polishing after anodic oxidation (not conductive, can be dyed a variety of colors); chromate oxidation (also known as conductive oxidation, there are two kinds of naturd color, gold yellow).


1. material thickness general tolerance + 0 - 0.08, e.g. the plate thickness 2.0mm, measured may be only 1.92mm.


2. Measuring material thickness shall be used micrometer . Do not use vernier caliper


3.must pay attention to the protection of aluminum processing, not to scratch the surface, bending to prevent cracks, bending block mark. If the material is too hard, it can be annealed or increase the lower die groove

Galvanized steel plate

SPGC

/

1, white metal luster, the surface has pattern, the surface is not easy to rust, but will produce white rust due to corrosion.


2, generally do not do surface treatment.


3, can not do electroplating (coated with colorful zinc, white zinc plating, nickel plating, tin plated...).


4, suitable for refrigeration, air conditioning, heavy electrical machinery, roof structures parts.

1. material thickness general tolerance + 0 - 0.08, e.g. the plate thickness 2.0mm, measured may be only 1.92mm.


2. Measuring material thickness shall be used micrometer . Do not use vernier caliper.


3.If the parts need bending, we must pay attention to whether the surface zinc layer fall off, and timely remove the lower mold Zinc powder

Hot rolling steel

SPHC、HRS 

/

1, black gray luster, the surface is not easy to scratch, but easy to rust spots, processing must pay attention to remove.


2, not suitable for electroplating (zinc plating-colorful , zinc plating-white,nickeling,tinning...).


3, suitable for baking varnish and powder coating and other structural parts.


1. material thickness general tolerance + 0 - 0.08, e.g. the plate thickness 2.0mm, measured may be only 1.92mm.


2. Measuring material thickness shall be used micrometer . Do not use vernier caliper


3. After processed will be daub anti-rust oil or cover with tarpaulin to prevent workpiece rust.


4.If the parts are to be electroplated, they must be sand blasting or brushing to remove the carbonized layer
