Close Tolerance CNC Machining for Casting and Custom Parts
What is CNC Machining?
Kingrun Technology offers Computer Numerical Control (CNC) machine shop services to complement our die casting services. Having this secondary option ensures that our clients receive the product that meets their requirements, We utilize custom CNC machining for finishing or fine-tuning aluminum die cast parts.
While some die cast parts require only simple finishing processes, such as drilling or metal removal, others need high-precision, post machining to achieve the part’s required tolerance or improve its surface appearance. With several CNC machines, Kingrun performs in-house machining of our die cast parts, making us the convenient single-source solution for all your aluminum die casting needs.
Aluminum die casting combined with CNC machining offers a comprehensive manufacturing solution for producing high-precision, complex aluminum parts. Die casting creates the initial shape, while CNC machining provides tight tolerances, surface finishing, and features that casting cannot achieve. This combination is ideal for automotive, aerospace, telecommunications and electronics industries requiring durable, lightweight components.
Key Aspects of Aluminum Die Casting + CNC
Production Cycle: Involves mold design/tooling, high-pressure molten metal injection, and post-cast CNC machining for final accuracy.
Advantages: High volume production with great surface finish, high strength, and dimensional accuracy.
Applications: Automotive body& covers, vehicle housings, electronic housings,and industrial equipment.
Key Casting Materials: Typically uses aluminum alloys like
● ASTM Standard A380, A383, A360,A356.
● JIS Standard ADC12,ADC10 etc.
● EN Standard ENAC-43400,ENAC-44300,ENAC-46000.

CNC Process
The CNC machining process is fairly straightforward. The first step is engineers designing the CAD model of the part(s) you need for your project. The second step is machinist turning this CAD drawing into the CNC software. Once the CNC machine has the design you will need to prepare the machine and the final step would be executing the machine operation. An additional step would be to inspect the completed part for any errors. CNC Machining can be broken into various types, mainly including:
CNC Milling
CNC milling rapidly rotates a cutting tool against a stationary workpiece. The process of subtractive machining technology then works by the material being removed from the blank workpiece by cutting tools and drills. These drills and tools rotate at high speed. Their purpose is to remove material from the workpiece using instructions originating from the CAD design in the early stages of development.
CNC Turning
The workpiece is kept in position on the spindle while rotating at high speed, while the cutting tool or central drill traces the inner/outer perimeter of the part, forming the geometry. The tool does not rotate with CNC Turning and instead moves along polar directions radially and lengthwise.
Almost all materials can be CNC machined; the most common material we can do includes:
Metals - Aluminum(Aluminium)alloy: AL6061, AL7075, AL6082, AL5083,steel alloy, stainless steel and brass, copper
Our capability of CNC machining
● Possesses 130 sets of 3-axis, 4-axis and 5-axis CNC machines.
● CNC lathes, milling, drilling and taps, etc. fully installed.
● Equipped with a processing center that automatically handles small batches and large batches.
● The standard tolerance of components is +/- 0.05mm, and tighter tolerances can be specified, but pricing and delivery may be affected.
Kingrun’s assembly department has expanded into leak testing in high level through helium test machines, and helicoil insertion,laser marking. We also purchase some components and do manual assembly when required. This allows the parts to be shipped to the customers ready for use.
Kingrun’s Quality Assurance shop ensures that the product being shipped meets every customer’s standards for low or high volume CNC machining production. We have a coordinate measuring machine which can handle in-process checks to first piece layouts, PPAPs and Quarterly statistics.
For all your die casting machining needs, Kingrun offers a comprehensive, quality solution.
