Shallow draw is a type of stamping process, usually referring to a processing method with a small degree of material deformation or a shallow forming depth,
especially common in the shallow drawing process. The following is a detailed analysis:
1. Basic concept
Definition: Shallow draw is mainly used for forming processes with small deformation, such as shallow drawing, and the ratio of workpiece height to diameter (or side length) is usually less than 0.5. Compared with deep drawing, it requires less material flow and a simpler process.
Core process: Apply pressure to the sheet through the mold to cause plastic deformation to form shallow concave parts (such as disc-shaped and cover-like parts).
2. Process characteristics
Low deformation: The material extension requirement is low, and it is not easy to crack or wrinkle.
Single forming: Usually no multiple stretching is required, and one stamping can be completed.
Simple mold: The mold structure is shallow, the cost is low and the manufacturing cycle is short.
High efficiency: Suitable for mass production, such as tableware, electronic housing, etc.
3. Application scenarios
Typical products: shallow containers (dinner plates, lampshades), metal covers, automotive interior parts, etc.
Material applicability: low carbon steel, aluminum alloy, copper alloy and other medium ductility plates.
4. Difference from deep drawing
Deformation depth: shallow drawing workpieces are shallow (height-to-diameter ratio <0.5), while deep drawing requires multiple stretching (height-to-diameter ratio >0.5).
Process complexity: deep drawing requires anti-wrinkle pressing plate and multiple annealing, while shallow drawing simplifies the process.
Cost: Shallow drawing has lower die and maintenance costs.
5. Terminology
Shallow drawing is not a strictly standard term, but more of a common name in the industry, and may be confused with “shallow drawing”. The specific definition needs to be combined with the context or corporate standards.
Of course, shallow drawing is widely used in the manufacture of shallow structural parts with its advantages of high efficiency and low cost. In addition, in sheet metal processing, the sheet metal factory will generally communicate with the customer in advance and explain what kind of metal parts require what kind of sheet metal process, because this involves processing costs. Finally, if you need to customize large quantities of sheet metal stampings, you can choose Mulan Group, because Mulan Group is a professional Chinese sheet metal stamping manufacturer that can provide complete sheet metal processes for metal products, with a quick turnover, ensuring that you can get strong business support.
