In which industries are automotive stamping parts applied

        Automotive stamping parts are the core components of automobiles made through the "stamping process" (using molds to apply pressure to metal sheets, causing them to undergo plastic deformation or separation, forming specific shapes). Their application is not limited to the automotive manufacturing industry itself, but extends to multiple industries related to "metal structural components and functional components" due to their characteristics of "high precision, high consistency, low cost, and high strength". The following provides a detailed analysis of its specific application scenarios from two dimensions: core application areas (automotive manufacturing) and extended application areas:

1、 Core application area: Automotive manufacturing industry (covering the entire vehicle system)

       Automobiles are the carrier of stamped parts, and the proportion of stamped parts in a passenger car can reach 30% -40% (calculated by the number of parts), covering core systems such as the body, chassis, power, and electrical systems. They are the key support for the "lightweight, safety, and economy" of automobiles.

1. Vehicle body system: determines the appearance and safety of the car

       The body is an application scenario for stamping parts, and almost all body coverings and structural components are stamped. The core function is to "shape the body shape+withstand collision forces":

       Vehicle body covering parts: "shell type" accessories with visible appearance, requiring high precision (ensuring uniform gaps in the vehicle body) and high flatness (avoiding appearance defects), such as:

       External coverings: door panels, hood (engine hood), trunk lid (trunk lid), roof cover, fenders (fenders above the wheels);

       Inner covering parts: door inner panel, dashboard frame (metal frame supporting dashboard), seat rail fixing plate.

       Body structural components: "Load bearing" accessories hidden under the cover, requiring high strength (anti collision deformation), often made of high-strength steel stamping, such as:

       Frame type: front longitudinal beam (to withstand frontal collision force), rear longitudinal beam (to withstand rear collision force), threshold beam (load-bearing beam under the door), B-pillar (vertical support column in the middle of the door, to protect against side collisions);

       Connection type: body pillar connection plate, crossbeam (lateral support between roof and chassis).

2. Chassis system: ensuring the stability and handling of the vehicle during driving

       The stamping parts of the chassis system need to withstand a composite load of "road impact, vehicle weight, and power transmission", with the core requirement of "high strength+high rigidity". The main applications include:

       Driving system: wheel hub (some lightweight wheel hubs are stamped), suspension arm (metal arm connecting the wheel and the body, controlling the wheel movement trajectory), stabilizer bar bracket (fixing the stabilizer bar to reduce body roll);

       Steering system: steering knuckle (connecting steering gear and wheels, transmitting steering force), steering rod fixing plate;

       Braking system: brake pedal (metal pedal that transmits braking force), brake caliper bracket (fixed brake caliper, bearing frictional force during braking).

3. Power system: transmitting power and withstanding high temperature and high pressure

       The stamping parts of the power system need to be adapted to the high temperature (engine operating temperature can reach 90-120 ℃) and high pressure environment of the "engine and gearbox", requiring "high temperature resistance+sealing". The main applications include:

       Surrounding areas of the engine: engine oil pan (metal shell for storing engine oil to prevent oil leakage), cylinder head cover (covering the cylinder head to protect internal components), intake pipe flange (metal joint connecting the intake pipe to the engine to ensure airtightness);

       Surrounding parts of the gearbox: gearbox housing (some lightweight housings are stamped), clutch pressure plate (the core component that transmits engine power to the gearbox, requiring high strength and wear resistance).

4. Electrical and auxiliary systems: supporting the realization of automotive functions

       These types of stamping accessories are mostly "functional small parts" that require "high precision+adaptability" to ensure correct coordination with electronic components and auxiliary equipment:

       Electrical system: battery casing (protecting car batteries from collision damage), motor end cover (covering the motor, dustproof and waterproof), wire harness fixing bracket (fixing wires to avoid wear and tear);

       Auxiliary systems: air conditioning duct bracket (fixing air conditioning duct), wiper bracket (fixing wiper motor), fuel tank bracket (fixing car fuel tank).

2、 Extended application areas: Cross industry "universal metal structural components"

       Due to the mature manufacturing process (standardized molds), stable performance (metal materials can be selected as needed), and controllable cost (low unit price for mass production) of automotive stamping parts, their technology and product forms have been widely replicated in other industries that require "high-precision metal structural components", mainly including the following fields:

1. New energy industry: adapting to the demand for "lightweight+high safety"

       The demand for metal parts in the field of new energy (especially new energy vehicles and energy storage equipment) is highly compatible with the automotive industry, and the automotive stamping process can be directly reused

       New energy vehicles: In addition to the body and chassis stamping parts commonly used in traditional cars, it also includes a battery pack cover (a metal cover that protects the battery module, requiring lightweight and waterproof), a battery module bracket (a metal frame that fixes a single battery, requiring insulation and high strength);

       Energy storage equipment: shell of energy storage battery cabinet (stamped metal cabinet, dustproof and waterproof), battery bracket (metal part that fixes the energy storage battery and bears the weight of the battery), photovoltaic bracket connector (stamped part that connects the photovoltaic panel and bracket, wind resistant).

2. Home appliance industry: meeting the dual needs of "appearance and function"

       The metal accessories in the home appliance industry need to be "beautiful and durable", and the "high precision and high consistency" characteristics of automotive stamping can improve the quality of home appliance products. The main applications include:

       White goods: refrigerator shell (some refrigerators have metal stamped shells with better texture than plastic), washing machine inner cylinder flange (a metal part connecting the washing machine inner cylinder and the motor, capable of withstanding high-speed rotational force), air conditioning outer unit shell (stamped metal shell, resistant to wind and rain corrosion);

       Black household appliances: TV backboard (metal frame supporting display screen, lightweight+rigid), audio shell (metal stamped shell, enhancing sound quality resonance).

3. Construction Machinery Industry: Adapting to the Demand for "Heavy Load+Wear Resistance"

       Construction machinery (such as excavators, loaders, and cranes) need to withstand heavy loads (up to tens of tons per load) and strong impacts (soil resistance during excavation). The "high-strength steel process" of automotive stamping can meet their needs, and its main applications include:

       Structural components: excavator bucket teeth (stamped wear-resistant steel parts that withstand friction during excavation), loader cab frame (metal frame that protects the driver and resists collisions);

       Connecting components: Crane arm connecting plate (a metal part that connects the arm section and bears the lifting weight), engineering machinery wheel bracket.

4. Rail transit industry: meets the requirements of "high safety+standardization"

       The components of rail transit (subway, high-speed rail) must meet "mandatory safety standards (such as collision resistance and fire prevention)", and the "standardized production+high strength" characteristics of automotive stamping can be adapted. The main applications include:

       Car components: subway car shell (stamped aluminum alloy sheet, lightweight and corrosion-resistant), car seat frame (metal frame supporting the seat, requiring high strength and durability);

       System components: track connectors (stamped parts that connect steel rails to ensure smooth tracks), brake system brackets (similar to the principle of automotive braking systems, capable of withstanding braking forces).

5. Medical device industry: meeting the demand for "high precision+sterility"

       Some medical devices (especially surgical instruments) require "high-precision adaptation (such as the bite degree of surgical instruments)+easy disinfection (smooth metal surface without dead corners)", which can be achieved through the "precision mold process" of automotive stamping. The main applications include:

       Surgical instruments: surgical scissors blade (stamped and polished to ensure sharpness), hemostatic forceps holder (metal part supporting hemostatic forceps, requiring high strength and not easily deformed);

3、 Core advantages of cross industry application of automotive stamping parts

       The fact that automotive stamping parts can extend from the "automotive industry" to multiple fields is essentially due to their three irreplaceable advantages:

       Cost advantage: Automotive stamping adopts "batch mold production", and a set of molds can produce tens of thousands to hundreds of thousands of products, with a much lower single piece cost than "CNC machining (single piece customization)", suitable for the large-scale needs of various industries;

       Performance advantages: Metal materials (such as high-strength steel for automobiles, aluminum alloys for household appliances, and stainless steel for medical devices) can be selected according to industry needs, and hardness and toughness can be adjusted through the "stamping+heat treatment" process to meet the performance requirements of different scenarios;

       Precision advantage: The precision of automotive stamping molds can reach ± 0.01mm, which can meet the high requirements of "component adaptability" in industries such as new energy and medical devices (such as correct docking of battery pack accessories to avoid leakage).
