Q Sheet metal parts applications

A The following are some common examples of sheet metal part processing:
Chassis and cabinets: Used to accommodate electronic equipment, servers, etc., with good protection and heat dissipation functions.
For example, the computer main chassis is realized with precise dimensions and holes through sheet metal processing to adapt to the installation of internal components.
Ventilation ducts: Widely used in air conditioning and ventilation systems.
Like the ventilation ducts in factories, they are made into specific shapes and sizes through sheet metal bending, splicing and other processes.
Electrical appliance shells: Such as the shells of refrigerators and washing machines.
Take the refrigerator shell as an example, it forms a complex shape and structure through sheet metal stamping, stretching and other processes.
Automobile body parts: Including car doors, engine covers, trunk lids, etc.
Car doors go through multiple processes such as sheet metal cutting, stamping and welding to meet the requirements of strength and appearance.
Metal shelves: Used for warehouse storage and display of goods.
Warehouse shelves ensure load-bearing capacity and stability through sheet metal processing.
Elevator car shells: Provide passengers with a safe and beautiful environment.
The shell of the elevator car is carefully designed and fabricated by sheet metal to meet the dual requirements of strength and decoration.
For example, when making ventilation ducts, sheet metal plates need to be cut and bent according to the actual space and air volume requirements, and connected into duct shapes through welding or riveting. For automotive body parts, in order to achieve lightweight and high strength, high-strength steel plates will be used and combined with advanced stamping and mold technology to complete the processing.

Q CNC lathe parts applications

A The following are some common processing examples of CNC lathe parts:
Automotive transmission shaft: This is a key component in the automotive transmission system, which requires high-precision outer circle, inner hole and thread processing to ensure precise matching and smooth transmission with other components.
Motor shaft: Used in motors, it usually requires strict dimensional accuracy and surface finish to ensure the stable operation and high efficiency of the motor.
Medical device parts: For example, handles and connectors of surgical instruments, etc., have very high requirements for accuracy and hygiene standards.
Aerospace components: Such as some components of aircraft landing gear, shaft parts inside the engine, etc., need to work under extreme conditions, so there are extremely high requirements for materials and processing accuracy.
Mandrels and guide pillars in molds: They play the role of guidance and support in mold manufacturing, and the accuracy directly affects the quality and service life of the mold.
Precision ball screws: Used in the transmission system of equipment such as CNC machine tools, it requires high-precision thread and cylindrical surface processing.
Connectors and plugs in electronic devices: To ensure good electrical connection performance, they usually have complex shapes and strict size requirements.
For example, when processing an automotive transmission shaft, the outer circle of the shaft needs to be turned by a CNC lathe first, and then the inner hole and thread are processed. During the processing, the cutting parameters and the selection of tools must be strictly controlled to ensure that the straightness, roundness and surface roughness of the shaft meet the design requirements. Another example is that for parts in the aerospace field, due to the particularity of their working environment, materials that are resistant to high temperatures and high strength may be used, and special heat treatment and surface treatment are also required after processing to improve the performance and reliability of the parts.

Q What are the factors affecting the precision of die-cast parts?

A

The following are some factors affecting the precision of die-cast parts:
Mold design and manufacturing:
The rationality of the mold structure directly affects the dimensional and shape precision of the castings. For example, the design of the parting surface of the mold, the layout of the runner and the overflow system, etc.
The manufacturing precision of the mold, such as dimensional tolerance and surface roughness, will be transferred to the die-cast parts.
Die-casting process parameters:
Control of die-casting pressure and speed. Insufficient pressure or improper speed may lead to insufficient filling of the molten metal, resulting in dimensional deviation.
Pouring temperature and mold temperature. Both too high and too low temperatures will affect the fluidity and solidification process of the molten metal, thereby affecting the precision.
Die-casting materials:
The composition and properties of the alloy will affect the shrinkage rate of the castings, and then affect the dimensional precision.
The purity of the raw materials may also cause defects such as pores and inclusions in the castings, affecting the surface quality and precision.
Die-casting equipment:
The clamping force of the equipment. If the clamping force is insufficient, the mold may expand during the die-casting process, resulting in dimensional deviation.
The stability and accuracy of the equipment, such as the precision of the injection system, etc.
Demolding slope:
Too large or too small demolding slope will affect the dimensional and shape precision of the castings.
Post-processing technology:
Post-processing operations such as deburring, polishing, and cutting. If not handled properly, it may change the size and shape of the castings.
Shrinkage and deformation:

Q Advantages of the CNC machining

A Advantages of the CNC machining process for hardware parts:
High precision: It can achieve very high machining precision, usually reaching the micron level, thereby meeting application scenarios with extremely high requirements for part precision.
For example, in the aerospace field, the machining precision of some key components directly affects the performance and safety of aircraft.
High repeatability: As long as the program and parameters are set correctly, the machined parts have a high degree of consistency and repeatability.
For batch production of hardware parts of the same specification, it can ensure the stable quality of each part.
Complex shape processing ability: It can easily process various complex geometric shapes, including curved surfaces, special-shaped structures, etc.
Complex components inside automotive engines, for example, are often manufactured using the CNC machining process.
High production efficiency: The degree of automation is high, and a large number of processing tasks can be completed in a short time.
Especially in large-scale production, it can significantly improve production efficiency and reduce production costs.
Disadvantages of the CNC machining process for hardware parts:
High equipment cost: The purchase and maintenance costs of CNC machining equipment are high.
For some small enterprises or manufacturers with limited funds, it may cause greater economic pressure.
High programming technical requirements: Professional programmers are required to write the processing program, and the technical level of the operators is required to be high.
Wrong programming may lead to processing errors, resulting in material waste and increased time costs.
Tool cost: High-quality tools need to be used during the processing, and the cost of these tools is relatively high and needs to be replaced regularly.
Especially when processing materials with higher hardness, the wear of the tools will be faster.
Not suitable for small batch production: For small batch and single-piece production, the cost allocation is relatively high and may not be as economical as traditional processing methods.
