자동차 다이캐스팅이란?
In its simplest terms, automotive die casting is a manufacturing process where molten metal is introduced into a die to create a part that solidifies in a fraction of a second. As the process unfolds, the metal comes in, the part is formed, and then it is processed down the line. It is high-speed, high-precision, and incredibly efficient for mass production.
There are two main types of this process:
Pressure Die Casting (PDC): Where molten metal is injected under high pressure into a steel mold. According to the North American Die Casting Association (NADCA), this remains the fastest way to produce complex non-ferrous metal parts.
중력 다이 캐스팅: Where molten metal flows into the mold due to gravity. This is often used for parts where the mechanical properties of a slower solidification are preferred.

Choosing the Right Alloy for Automobile Die Castings
When a new customer comes to us, we look at tolerances, part size, and various features to pinpoint the right alloy. Here at The Die Casting, we have the ability to cast all three main alloy types, ensuring that we match the material to the specific application:
- 알루미늄: This is sort of the go-to. It provides the best overall value of properties and economics. It has excellent thermal conductivity properties to get the heat out of electronics.
- 마그네슘: If it’s something that is going to be in a very weight-sensitive application and you need very, very light weight, we suggest magnesium. It offers an incredible strength-to-weight ratio and is excellent for headlamp ballasts.
- 아연: A heavy alloy, about two and a half times heavier than aluminum. However, you can do thinner walls and less draft, and the tool life is much, much better in zinc.
High-pressure die castings have ever-increasing use in automotive manufacturing processes and technology. With the increasing amount of electronics and passenger cars and trucks, there is a much greater need for mechanical type systems that can dissipate heat, add structural integrity, and other factors that make high-pressure die castings a very popular product and components for the automotive sector. This guide explores the secrets of the trade, explaining why automotive die casting is a major leap over traditional methods.
Automotive Aluminum Die Casting in the Era of Electric Cars
The future of the car industry will be pure battery electric vehicles. In this new era, automotive 알루미늄 다이캐스팅 is essential because the powertrain looks completely different. In the vast majority of electric vehicles, there is only one gear, so the gearbox is much smaller and less complicated.
However, we have some new parts that come with e-mobility. The inverter on top contains a lot of electronic components and needs to be completely pressure tight. We cannot accept any leakage; while oil leakage in an internal combustion engine is not nice, water leakage can kill the motor of an electric car once it’s filled with water. Therefore, automotive aluminum die casting must meet the highest standards of structural integrity.

Die Casting Manufacturing
Install a aluminum die casting tooling on the die-casting machine, and spray lubricant to the cavtiy and core side (release agent) to control the mold temperature and facilitate demolding. We have aluminum die casting machines from 120 to 1250 tonnages
Casting Runner Trimming
The main methods for removing gates (runner) from die castings include in-mold cutting, stamping tooling with a dedicated edge trimming machine, sawing, or robotic cutting. Depending on the complexity and material of the casting, automated mechanical stamping is the mainstream choice to ensure efficiency and surface quality.
Die Casting Deburring
Manual or robotic methods, along with grinding wheels and files, are used to perform fine polishing on specific or complex areas. Sometimes, robots are used to hold the cutting tool or grip the workpiece to automatically remove complex burrs from the surface and openings.
Die Casting CNC Machining
After cleaning, the die-cast parts are fixed on the fixture of a CNC machine tool. According to the programming code, they are milled, drilled, tapped or turned to produce high-precision holes, threads or planes, solving the complex features that die casting cannot directly form, at CNM Casting, we always adapt to new technologies in this sector to introduce these advancements to our clients.
Die Casting Surface Finish
The surface treatment process for die-cast parts mainly includes: pretreatment (degreasing, rust removal, grinding/polishing/sandblasting), pretreatment cleaning, and core surface treatment (such as anodizing, powder coating, spraying, electrophoresis, electroplating, and passivation). The purpose is to remove casting defects, increase surface hardness, improve corrosion resistance, and enhance aesthetics.
Final Inspection and Packing
After die casting, the process includes gate and flash removal, preliminary cleaning, visual and dimensional inspection, surface treatment, finished product marking and traceability, cleaning, final inspection, protective packaging, and warehousing. The focus is on ensuring surface quality and dimensional accuracy meet requirements, and preventing bumps and scratches during transportation to achieve high-quality, traceable product delivery.
Producing Complex Automotive Die Casting Parts
Automotive die casting parts run from “head to tail” in a modern vehicle. Because everything you do to reduce weight helps fuel economy and reduces emissions, these components are vital.
Power Electronics and EV Housing
Electric vehicle electronics generate heat, and you want to get that heat out. We use automotive aluminum die casting for:
- TCM Modules: Transmission control modules for shift-by-wire systems.
- EV Enclosures: Large housings that need to be a leak-free product to prevent water intrusion.
- EMI/RFI Shielding: Die castings inherently protect electronics from interference compared to plastics.
Structural and Mechanical Die Casting Automotive Parts
- Shock Towers: High-pressure castings that replace sheet metal assembly and welding, increasing rigidity.
- Motor Housings: Which stay a big portion of the die casting business as we switch to electric mobility.
- Battery Boxes: Large parts that are now being cast as a single piece to ensure they stay watertight.
Investment Casting and Automobile Die Castings
When die casting automotive parts require very high dimensional accuracy or represent a small and intricate design, we may look at Investment Casting, also known as the Lost Wax Method.
Manufacturing Excellence: Cold Chamber vs. Hot Chamber
In automotive die casting, the way metal is introduced into the die is critical to the quality of the final part.
핫 챔버 다이 캐스팅
Used for zinc and magnesium, the injection systems are actually physically inside the molten metal. A plunger comes down, extracts a given amount of material, and pushes it into the die. It’s a very fast process, sometimes it looks like popcorn coming out because it cycles so quickly.
콜드 챔버 다이 캐스팅
Typically for aluminum, the metal is in a separate furnace. A ladle picks up a predetermined amount of liquid and puts it into the shot sleeve. This prevents the molten aluminum from attacking the plunger mechanisms.
Value-Added Processes: Beyond the Casting
At thediecasting.com, we love doing engineering and technical experience work. We look at the overall application to see if we can combine parts into a single die cast part to reduce costs.
- In-house CNC Machining: We have the ability to handle a very wide range of machining, from simple drill/tap stations to complex 5-axis work.
- Leak Testing: For parts that need to be leak-free, we set up pressure decay leak testing. We inject the part with air and measure the amount escaping to confirm we ship a leak-free part.
- 표면 처리: We apply various surface treatments and different finishes, from vibratory deburring to high-level corrosion protection.
Sourcing from Automotive Die Casting Manufacturers in China
For global manufacturers, sourcing from automotive die casting manufacturers in China provides a significant advantage. At CNM Casting, we take pride in the fact that we help you get your “most bang for the buck” with a die casting. Our China-based facility allows us to be highly competitive on part price because we prioritize engineering efficiency.
Modern automobile die castings in China utilize AI-driven vacuum die casting. A vacuum is applied to remove air, which reduces porosity and improves strength and surface quality. This allows us to offer suggestions that might help save the customer money by doing features “as cast” rather than through secondary machining.
