★Deep drawing stamping:
Sensorgehäuse
Deep drawing stamping is a special stamping method. The principle is to apply external force to sheets, strips, pipes and profiles by means of presses and dies to cause plastic deformation or separation, so as to obtain workpieces of the required shape and size ( Stamping). However, deep drawing stamping is quite different from common continuous stamping and single-action stamping.
The first is the mold. The mold consists of a punch and a die. One station has a pair of molds, generally up to 18 stations. When designing the mold, it is usually considered to use all the stations, which makes the molding of the product more stable at each step. , the product comes out with better effect;
The second is the material belt. The deep drawing process is conveyed without material belt. The product exists alone in the mold and is conveyed between stations by the built-in manipulator, which can be reversed at will, which allows us to form relatively complex shape features. Such as: thread, side hole, side groove, reverse stretching of end face, etc., can produce various products.
Compared with machined parts, casting parts, molded parts and ordinary stamping parts, it has obvious advantages such as saving material cost, reducing waste, reducing assembly cost and time, etc. By improving the appearance and structure of the product to meet the requirements and retain its own strength, effectively The use of raw materials to minimize the waste rate.
★Application analysis of deep drawing of different materials
Ultra Deep Drawing Press Processing
1. Low carbon steel drawing and stamping
a. Material properties:
Excellent formability (depending on material grade), high strength, light weight, better cost performance than other stretched materials, dimensionally stable forming, low corrosion resistance, requires post-processing protection such as electroplating. Commonly used in various parts and components in automobile manufacturing, especially high-strength structural parts.
b. Influence on the drawing and stamping process:
Rich material procurement resources
Low tonnage machines will do (depending on material grade)
Good dimensional stability after molding
Especially suitable for welding
There are different coatings in the raw material category, which can save subsequent surface treatment, such as electroplating
The molded product has a certain shelf life, which depends on its own corrosion resistance
c. Our commonly used low carbon steel materials:
1008 low carbon steel HSLA Grade 50 low carbon steel
1010 low carbon steel HSLA Grade 80 low carbon steel
DC03 / DC04 B340LA / B410LA
SPCC / SPCD / SPCE
2. Stainless steel drawing and stamping
a. Material properties:
High strength, light weight, high corrosion resistance, suitable for heat treatment, good wear resistance and does not require plating protection.
Commonly used in fuel supply systems, braking systems, emission systems, oxygen sensors and decorative parts in automobile manufacturing.
b. Influence on the drawing and stamping process:
Requires a large tonnage machine compared to other materials
Greater wear on the die during stretching
Materials are expensive
The size after molding has good stability ( /-0.02mm)
The material hardens quickly and is resilient when stretched
It is difficult to form the material during stretching, and it is difficult to control the wall thickness of the product. Experienced mold adjustment workers are required.
c. Our commonly used stainless steel materials:
304(L) stainless steel
305 stainless steel
310 stainless steel
316 stainless steel

430 stainless steel
Stainless Tube
3. Aluminum alloy drawing and stamping
A. Material properties:
Light weight (about 1/3 of mild steel), high strength, non-magnetic, non-rusting, suitable for heat treatment, and can be anodized to prevent corrosion.
Commonly used in automobile manufacturing and other industries in cooling devices, energy storage devices (such as batteries), beverage containers and pharmaceutical industries.
b. Influence on the drawing and stamping process:
Compared to other materials, low tonnage machines can
Greater wear on the die during stretching
The size after molding has good stability ( /-0.04mm)
Material is easy to form and has low resilience
The material does not harden easily when stretched
Aluminum alloy stretching is achievable for forming with inconsistent wall thicknesses
