The application and common problems of stamping metal parts.

Stamping is a forming processing method that relies on presses and dies to apply external force to plates, strips, pipes and profiles to produce plastic

deformation or separation to obtain workpieces of desired shape and size, including punching, bending, drawing, forming, finishing and other processes.

What are the common precision hardware stamping parts?

1、Automotive parts: It mainly contains automobile structural parts, automobile functional parts, automobile lathe parts, automobile relays, etc.

2、Electronic parts: mainly contains connecting devices, connectors, brush parts, electrical terminals, elastic parts, etc.

3、Home appliance parts: mainly contains large appliance parts, such as color tube electronic gun parts, and small home appliance parts, all kinds of

structural and functional parts, etc.

4、IC integrated circuit lead frame: mainly contains discrete device lead frame and integrated circuit lead frame, etc.

5、 motor cores: mainly contains single-phase series-excited motor cores, single-phase household motor cores, single-phase shaded-pole motor cores,

permanent magnet DC motor cores, industrial motor cores, plastic stator cores, etc

6、Electrical core: mainly contains E transformer core, EI transformer core, I transformer core, and other transformer cores, etc.

7、Heat exchanger fins: mainly including industrial heat exchanger fins, household heat exchanger fins, automotive heat exchanger fins, etc.

8、Other parts: mainly including instrument parts, IT parts, acoustic and camera parts, modern office parts, and daily hardware, etc.

The common problems of hardware stamping processing include: deformation and burr of precision stamping parts; crack, warpage, surface abrasion and

corner deformation of bending parts; flange wrinkling, wall wrinkling, wall damage and pulling crack of deep-drawn parts; flanging cracks and uneven

expansion etc.

Maxswall specialized on metal parts processing with more than 30 years experiences.We have worked out a complete solution regards to the common problems

caused in the production.  Such as :

• Mold design should have reasonable convex and concave die clearance value, fillet radius and processing accuracy.

• When designing the bending die, take effective measures to reduce the rebound and subtract the amount of rebound from the die; design reasonable

rounded corners to prevent bending cracks.

• Use crimping ring to prevent wrinkling when drawing deep, and the pressure should be moderate; reduce the resistance of drawing deep with proper

lubrication to prevent the die from sticking or making the workpiece pull through.

• Use professional stamping oil that meets the requirements of the process.

We Maxswall are mainly engaged in screen printing, hardware stamping, structure assembly, etc., and constantly improve the surrounding supporting processes to

provide you with one-stop production services for electronic products' nameplate, LOGO,membrane switch, metal parts,sheetmetal parts and so on.
