Stamping process and brief introduction in the production of home appliance shells

As an important part of home appliances, home appliance shells carry multiple functions of protecting internal components, improving product appearance and enhancing structural strength. As the home appliance market continues to increase its requirements for product quality and design, stamping technology plays a key role in the production of home appliance shells. Stamping technology can not only improve production efficiency, but also ensure the high quality and stability of the shell. This article will briefly introduce 20 common stamping processes and their applications in the production of home appliance shells, which we will discuss separately in subsequent articles.

1. Cutting

Applied products: washing machine shells, refrigerator inner and outer panels

Introduction: Cutting metal sheets through punching machines and dies to obtain raw sheets of the required shape. Suitable for cutting large sheets into sizes and shapes suitable for further processing.

2. Bending

Applied products: air conditioner shells, microwave oven shells

Introduction: Bend the metal sheet at a specified position to form the edge or folded edge of the shell. Used to create home appliance shells with angles or curves.

3. Deep Drawing

Applied products: refrigerator door panels, washing machine drums

Introduction: The flat metal is stretched into a deep concave shape through a die, which is suitable for the production of complex three-dimensional shells, such as cylinders or deep concave panels.

4. Punching

Applied products: air conditioner radiator shell, home appliance chassis vents

Introduction: Punching holes in metal sheets, often used to make functional openings such as vents and heat dissipation holes.

5. Blanking

Applied products: induction cooker panels, washing machine control panels

Introduction: Punching metal sheets into predetermined edges or openings. Mainly used to make the initial shape of parts and components to facilitate subsequent processing.

6. Forming

Applied products: oven shell, refrigerator insulation board

Introduction: The metal sheet is formed into complex geometric shapes, such as bending or folding, through a die to meet the design requirements of the shell.

7. Curling

Applied products: air conditioner housing edge, oven door frame

Introduction: Curling the edge of the metal sheet is usually used to strengthen the edge of the housing, avoid sharp edges and improve structural strength.

8. Pressing

Applied products: microwave housing, washing machine chassis

Introduction: Using high pressure to press the metal sheet into the required shape, suitable for mass-produced parts such as chassis and housing.

9. Cold Stamping

Applied products: home appliance housing bracket, refrigerator liner

Introduction: Stamping the metal sheet at room temperature, suitable for high-precision, high-strength home appliance housing parts, maintaining the original performance of the material.

10. Hot Stamping

Applied products: high-strength home appliance housing, oven door panel

Introduction: Stamping in a heated state to improve the plasticity of the metal, suitable for manufacturing housing parts with high strength requirements.

11. Stamping Welding

Applied products: Air conditioner shell seams, refrigerator frames

Introduction: Connect metal parts by combining stamping and welding to enhance the structural strength and durability of the shell.

12. Die Forging

Applied products: Metal brackets for home appliances, internal structural parts of microwave ovens

Introduction: Forging after heating the metal through a die to improve the strength and durability of the metal, suitable for the production of structural parts.

13. Compound Forming

Applied products: Complex-shaped home appliance shells, smart home appliance shells

Introduction: Combine multiple forming processes to achieve the production of complex shapes. Applicable to multifunctional and diversified home appliance shells.

14. Inlaying

Applied products: High-end home appliance panels, design decorative shells

Introduction: Inlay other materials or decorative elements in the metal shell to enhance the appearance and functionality, such as inlaying decorative strips or control panels.

15. Laser Cutting

Applied products: precision control panels, home appliance housing decoration parts

Introduction: Using laser technology to cut metal sheets can achieve high-precision cutting and complex shape processing.

16. Roll Forming

Applied products: home appliance housing frame, washing machine side panel

Introduction: The metal sheet is processed into a specific cross-sectional shape through a continuous mold, which is often used to manufacture long or frame-type home appliance housing parts.

17. Surface Treatment

Applied products: sprayed microwave housing, electroplated refrigerator door panel

Introduction: The stamped housing is surface treated, such as spraying, plating, etc., to improve the corrosion resistance and aesthetics of the housing.

18. Joining

Applied products: air conditioner housing splicing, refrigerator partition

Introduction: Multiple metal parts are connected together through the stamping process to form a complete housing structure to ensure its stability and strength.

19. Electrophoretic Coating

Applied products: Washing machine shell, oven liner

Introduction: The electrophoretic coating process is used to coat the metal shell to provide a uniform protective layer and improve corrosion resistance and wear resistance.

20. Prototype Molding

Applied products: New home appliance shell samples, shell testing in the product development stage

Introduction: The mold samples made in the product development stage are used to test and verify the design to ensure that the final product meets the design requirements and performance standards.

These processes cover all aspects of the production of home appliance shells. Through different stamping technologies and processing methods, different needs and design requirements for the shell can be achieved.
