Types of Auto Parts Processing

Transmission Housing Part

The transmission housing is a typical housing part on the car. Traditionally, it uses a combination machine tool or a special machine tool, but now it is mostly made of flexible machining centers.

Converter Housing Part

The main function of the converter housing is to achieve a flexible connection between the engine and the transmission and drive the oil pump. This function makes the power transmission smoother and prevents the transmission system from overloading and the engine from stalling.

Clutch Housing Part

The machining process of the automobile clutch housing is a complex and delicate process involving multiple steps and strict technical requirements.

Valve Body Part

The processing of the valve part of automotive parts involves multiple steps, including raw material preparation, cutting, rough machining, heat treatment, finishing, cleaning, assembly, surface treatment, etc.

Engine Cylinder Block

The cylinder body is strictly called the cylinder block - the crankcase! Because the upper part is one or several cylinders, the lower part is the crankcase supporting the crankshaft!

Automobile Subframe Part

The role of the auxiliary frame is to block vibration and noise and reduce its direct entry into the carriage, so most of them appear in luxury cars and off-road vehicles, and some cars also install the auxiliary frame for the engine.

Advantages of Auto Parts Processing

Precision Machining
This technique includes methods such as turning, milling, and drilling, which allow manufacturers to create intricate designs and tight tolerances essential for auto parts.

Advanced Tooling
Utilizing high-quality cutting tools ensures durable and efficient machining processes. The right tooling can significantly enhance the performance of CNC machinery.

Automation Integration

Incorporating robotics and automated systems into CNC operations streamlines processes further. Robots can assist in loading and unloading materials, enhancing productivity without compromising safety.

Quality Control Systems

Implementing real-time monitoring systems allows for immediate detection of deviations from desired specifications, ensuring that each part meets quality standards before it leaves the production line.

Additive Manufacturing

This innovative approach allows for the creation of complex geometries that traditional methods struggle with. CNC-compatible 3D printing can produce prototypes and custom parts rapidly.

Custom Auto Parts Surface Finishing Techniques

Surface finishing techniques for custom auto parts are essential to enhance aesthetics, protect against corrosion, and improve the overall quality of the custom car parts.The choice of surface finishing technique depends on factors such as the material of the part, its intended use, durability requirements, and desired appearance.
Here are some common surface finishing techniques used for custom auto parts.

Painting:
●Spray Painting: Applying paint using a spray gun to achieve a smooth and even finish.
●Powder Coating: Electrostatically applying dry powder to the part, which is then cured under heat for a durable finish.
●Automotive Clear Coat: A clear, protective layer applied over paint to provide gloss and protection.

Polishing and Buffing:
●Buffing: Using abrasive compounds and rotary buffers to remove imperfections and achieve a high-gloss shine on metal or painted surfaces.
●Chrome Plating: Applying a layer of chromium to metal custom car parts for a shiny, corrosion-resistant finish.

Anodizing:
The electrochemical process enhances the corrosion resistance and appearance of aluminum car parts by creating a protective oxide layer.

Ceramic Coating:
Applying a ceramic layer that provides long-lasting protection against UV rays, chemicals, and contaminants while enhancing gloss.

Hydrographics (Water Transfer Printing):
Immersing custom car parts in a water tank with a printed film, transferring the design to the part's surface for a customized appearance.

Vinyl Wrapping:
Applying vinyl sheets with various colors, patterns, or textures to completely cover a part's surface.

Brushing and Sanding:
Creating brushed or textured finishes on metals by sanding or using abrasive pads for a distinctive appearance.

Bead Blasting:
Using fine abrasive particles propelled by compressed air to clean, texture, or matte-finish surfaces.

Clear Film Protection (Paint Protection Film - PPF):
Applying transparent, self-healing film to protect painted surfaces from scratches, stone chips, and UV damage.

Electroplating:
Depositing a layer of metal (e.g., chrome, nickel) onto the part's surface to enhance aesthetics and provide corrosion resistance.

E-coating (Electrophoretic Deposition):
Submerging custom car parts in an electrically charged bath to apply a protective coating, especially for corrosion resistance.

Sandblasting:
Using abrasive materials like sand to clean, roughen, or prepare surfaces for painting or coating.

Metal Brushing:
Creating a brushed or satin finish on metals by brushing the surface with abrasive materials.

Tumbling and Vibratory Finishing:
Placing custom car parts in a rotating drum or vibrating container with abrasives and chemicals to smooth or deburr surfaces.

Enamel and Ceramic Paints:
Applying specialized enamel or ceramic paints for high-temperature parts like exhaust components.

FAQ

Q: What is the purpose of auto parts?

A: These parts play a crucial role in ensuring the smooth operation and performance of vehicles, making them an essential aspect of the automotive industry. The primary purpose of spare parts is to restore a vehicle to its optimal functionality and extend its lifespan.

Q: What are the automotive component standards?

A: For a component to be automotive qualified, manufacturers have to meet specific industry standards throughout the manufacturing and testing process. Three key standards are IATF 16949, AEC-Q100 and AEC-Q200: IATF 16949.

Q: How are automotive parts manufactured?

A: A blank piece of sheet metal is the starting point for many car parts. This metal is then reshaped, stamped, cut, and molded into the part needed. Presses are used to shape metal into curves. The right amount of pressure is needed or the metal won't retain the desired shape.

Q: Can you CNC car parts?

A: It is possible to produce simple or single-sided automotive parts using different CNC machines. However, more complex parts, such as cylinder heads and engine blocks, usually require expensive five-axis machining centers.

Q: Can you make custom plastic car parts?

A: Custom plastic components can be manufactured in a variety of ways and from a range of different materials. Generally speaking, custom plastic components are made through either injection molding, blow molding, rotational casting, extrusion or thermoforming.
