In-house Die casting tooling
Molds are crucial for die casting, as they determine the part’s shape, tolerance, surface finish, and internal quality. As a China die casting mold maker, we have extensive experience in this area.
Over 10,000 molds manufactured
All die casting moulds made in-house
Mold life: 60000-100000 shots
Moreover, we also provide free mold maintenance services.

aluminum die casting factory
We use both high-pressure and low-pressure die casting processes to meet various aluminum part production needs:
HPDC (High Pressure Die Casting): Suitable for lightweight, thin-walled, complex, precision, and high-volume aluminum castings.
LPDC (Low Pressure Die Casting): Ideal for heavier, thick-walled, high mechanical performance, and medium-volume aluminum castings.

CNC machining service
If a die casting manufacturer lacks its own CNC machining workshop, it can be challenging to ensure delivery times and quality. But at Sanon Casting, you don’t have to worry about that.
We offer not only die casting but also precision CNC machining services for complex designs and demanding tolerances.
- Accuracy: 7μm
- Surface roughness: Ra0.8
- Full dimensional inspection records provided

Various surface treatments
In-house: Shot blasting for a consistent matte surface
Outsourced: Powder coating, painting, passivation, chrome plating, zinc plating, electrophoresis, anodizing, and more.
Surface treatments enhance corrosion resistance, surface hardness, or aesthetics of the parts. Tell us your requirements, and we’ll provide the perfect solution.

Testing and Packaging
Testing: Surface inspection, dimensional measurement, X-ray inspection, penetrant testing (PT), leakage or sealing test, mechanical property testing, chemical composition analysis, etc.
Packaging: Good packaging is essential for long-distance transportation, as it can prevent parts from being bumped or scratched during transit.

Quality control capability
Inspecting aluminum castings is a key step in ensuring their quality, performance, and reliability. It effectively prevents quality defects, reduces potential risks, and ensures that the castings’ performance and lifespan meet the expected requirements. We strictly adhere to the IATF 16949 quality management system, and as a result, we have greatly benefited, significantly improving customer satisfaction.

Surface Check
Surface and near-surface defects, such as cracks, porosity, shrinkage, cold shut, flow marks, and deformation, are inspected through visual or penetrant testing (PT) to confirm the best surface quality.Â

Dimensional Inspection
Using tools such as calipers, micrometers, and Coordinate Measuring Machines (CMM) to ensure dimensional accuracy meets design specifications and provide full dimensional inspection reports.

X-ray Inspection
X-ray imaging is used to check for internal defects like porosity, inclusions, and cracks within the casting, which is particularly crucial for high-standard products like auto parts, and electrical parts, etc.

Mechanical Property Testing
Tensile strength, yield strength, hardness, elongation, Young’s modulus testing, etc., help verify that the casting has sufficient strength to handle the operational loads without breaking, deforming, or failing.

Leakage or Sealing Test
For castings requiring air or fluid tightness, such as engine housings, valve bodies, and pump casings, leakage tests (e.g., Air/Water Pressure Testing or Helium Leak Testing) are performed to confirm there’s no leakage.

Chemical Composition Analysis
Spectrometers or energy-dispersive X-ray fluorescence analyzers are used to check the chemical composition of the casting material to ensure alloy composition standards are met.
Materials
aluminum die casting alloys & applications
There are different types of cast aluminum alloys because each type is specifically engineered to meet various performance, application, and manufacturing requirements.
For HPDC, the commonly used aluminum alloy is ADC12.
For LPDC, the preferred aluminum alloy is A356.2.
