Precision Auto Parts: 5 Things To Know

Precision auto parts application in many automobile industries, as we know the brands Volkswagen, Honda, Chevrolet, Hyundai, etc. Each car has hundreds of thousands of precision parts, when find the precision auto parts for your car project, what is considered it?
Here are five ways to start.

1: What Are Materials Appropriate For Precision Auto Parts?

As we all know metal and plastic for CNC machining, but for the precision auto parts usually use metal.
The 5 series and 6 series aluminum materials used in precision auto parts processing, like 5 series, 5754、5182、 5023, 6 series 6061、6063、6016.
Aluminum alloy is the most abundant green metal in the earth’s crust. It is light and has high specific strength, and also is easy to shape, has good energy absorption and corrosion resistance, and has great recycling value. Therefore, it is regarded as one of the ideal materials for lightweight automobiles. Aluminum alloy was initially used in automobiles as heat exchanger component materials and then used in automobile wheels, engine cylinder pistons, cylinder blocks, and other components. A large number of aluminum alloy sheets are used for covering precision parts in automobile manufacturing.
Automotive connectors play an important role in car industries. These small connectors can pass power and signals between different systems, allowing various electronic devices to function properly. However, automotive connectors require properties such as high temperature resistance and pressure resistance. So, what kind of plastic is used in automotive connectors? In terms of production materials, the plastic raw materials commonly used in connectors mainly include PBT, 66, 6T, 9T, LCP, etc.

2: How To Design Precision Auto Parts 3D Drawings?

It’s about design drawings, every person thinks complex, in reality, yes, but we are a precision auto parts manufacturer, we had engineers focus on helping customers design drawings, he graduated in mechanical engineering, and is very familiar with designing 3D drawings, it will help you save time and cost for the project. When designing drawings, we also consider the parts design reasonable, and give you some advice.

3: What Is The Tolerance Of Precision Auto Parts?

Why do we consider precision when producing precision auto parts? the precision tolerance will influence the car’s operation. The precision is differentiated as fine f, medium m, rough c, and coarsest v. Fine f is roughly equivalent to IT12, medium m is roughly equivalent to IT14, rough c is roughly equivalent to IT15~IT16, and coarsest is no IT level comparison, these 4 tolerance levels are without your mark tolerances, It is GB standard tolerance. If you have a tolerance request, you can mark it in the drawings, like DIN ISO 2768, JIS2238, and BS5352. Different countries use different tolerance standards. We are a precision parts factory, and our parts always obey fine f, and the tolerance can be reached to ±0.01mm, if you have a special demand, please discuss it with us.

4: Why Consider Performance For Precision Auto Parts?

Auto parts are high precision, that require very high precision during processing, especially the engine part is the core component of the car. During the process of precision milling, grinding, and turning, if the engine part fails to meet the machining accuracy requirements may cause the parts seriously damaged or scrapped, resulting in huge cost losses. Therefore, the accuracy of the part determines the accuracy standard for auto parts processing.
Since there are so many types of precision auto parts, Let’s give some examples: crimp pin, shrapnel, lead frame, wire connector, selectively plated lead frame, selectively plated terminals, terminals, contacts, connectors, transfer lead frame.

5: How To Assemble Precision Auto Parts?

Assemble precision auto parts considering whole a project design, as we mentioned before, when we design 3D drawings, the precision auto parts dimensions need reasonable, because the parts are connected one by one, it is not a whole, so our engineers will calculate dimensions, it is successfully assembled parts
