Selection of stamping materials

Material selection of stamping parts:

The three most important steps in a stamping factory are shearing, punching / cutting and folding.

Stamping parts are sometimes used as metal pulling. The word comes from English platemetal. Generally, some metal sheets are pressed by hand or die to produce plastic deformation to form the desired shape and size, and more complex parts can be formed by welding or a small amount of mechanical processing, such as chimneys, tin furnaces and automobile shells commonly used in families. Stamping parts processing is called sheet metal processing. Specifically, for example, the use of plates to make chimneys, iron barrels, oil tanks, oil pots, ventilation pipes, large and small ends of elbows, Tianyuan places, funnel shapes, etc. the main processes are shearing, bending and edge buckle, bending forming, welding, riveting, etc., which requires certain geometric knowledge. Stamping parts are sheet metal parts, that is, parts that can be processed by stamping, bending, stretching and other means. A general definition is - parts with constant thickness in the processing process. The corresponding parts are casting parts, forging parts, machining parts, etc. for example, the iron shell outside the car is sheet metal, and some kitchen utensils made of stainless steel are also sheet metal.

Selection of materials

The materials commonly used in sheet metal processing include cold rolled plate (SPCC), hot rolled plate (SHCC), galvanized plate (SECC, SGCC), copper (Cu), brass, red copper, beryllium copper, aluminum plate (6061, 5052, 1010, 1060, 6063, hard aluminum, etc.), aluminum profile, stainless steel (mirror, wire drawing surface, fog surface). According to the different functions of products, different materials are selected, Generally, the use and cost of the product shall be considered.

1. Cold rolled sheet SPCC mainly uses electroplating and paint baking parts, with low cost, easy forming and material thickness ≤ 3.2mm.

2. Hot rolled plate SHCC, material t ≥ 3.0mm, is also electroplated and painted parts, with low cost but difficult to form, mainly flat parts.

3. Galvanized sheet SECC, SGCC. SECC electrolytic plate is divided into n material and P material. N material is mainly not subject to surface treatment and has high cost. P material is used for spraying parts.

4. Copper; It mainly uses conductive materials, and its surface treatment is nickel plating, chromium plating, or no treatment, with high cost.

5. Aluminum plate; Generally, surface chromate (j11-a) and oxidation (conductive oxidation and chemical oxidation) are used, with high cost, including silver plating and nickel plating.

6. Aluminum profile; Materials with complex cross-section structure are widely used in various plug-in boxes. The surface treatment is the same as that of aluminum plate.

7. Stainless steel; It is mainly used without any surface treatment and has high cost.
