Aluminum Casting and Precision Machining Service Capability
We organize our aluminum casting and machining services into four key areas based on our customers’ core needs, covering every step from raw materials to finished products.
Aluminum Casting Core Processes
Based on your product design, production volume, and performance requirements, Matech recommends the most suitable casting solution for your needs -rely on our extensive experience in casting processes and manufacturing capabilities.
Matech's gravity casting production lines specialize in manufacturing medium to large-sized aluminum components with relatively complex geometries. We utilize high-precision metal molds and optimized gating systems to ensure smooth filling of molten metal and produce dense castings with minimal porosity. Based on our deep process expertise, we precisely control cooling rates to minimize shrinkage defects, providing a reliable blank foundation for structural components such as automotive engine mounts and gearbox housings.
Typical applications: gearbox housings, large brackets

In the realm of low-pressure casting, Matech achieves precise control over mold-filling pressure and holding duration, facilitating the smooth, upward flow of molten metal into the mold cavity. This process yields castings with a dense microstructure and superior mechanical properties. Compared to traditional gravity casting, this technique significantly minimizes internal porosity and enhances product yield, establishing it as the optimal solution for high-performance structural components.
Typical applications: cylinder heads, high-performance structural parts

Frequently Asked Questions
1
What casting processes does Matech offer for aluminum castings?
Based on part geometrical structure, performance requirements, and production volume, we flexibly apply gravity casting, low-pressure casting, and high-pressure casting(die casting). Gravity casting is suitable for medium-to-large structural components. Low-pressure casting offers high density and excellent pressure tightness, making it ideal for parts demanding superior internal integrity, mechanical properties, and surface finish. Die casting provides high efficiency and is well-suited for large-volume production of thin-walled, complex parts. To recommend the most appropriate process, we require the customer to provide product drawings and technical specifications for analysis and consultation.
2
What machining accuracy can be achieved for aluminum castings?
Our facility is equipped with high-precision CNC machining centers, capable of achieving dimensional tolerances of ±0.005 mm. Concentricity and positional tolerances can be controlled within 0.01–0.05 mm. Critical mating surfaces can be ground or polished to a surface roughness of Ra 0.4–0.8 μm. All geometric dimensions can be inspected using CMM (coordinate measuring machine), and inspection reports are available upon request.
3
How do you control porosity, shrinkage cavities, and other defects in aluminum castings?
We optimize the gating system using casting simulation software. Low-pressure casting significantly reduces porosity, while die casting controls solidification through precision tooling. Finished castings can be subjected to X-ray or penetrant testing as required.
4
Can aluminum castings replace steel castings to reduce equipment weight?
Partial replacement is possible. For applications with low strength and rigidity requirements — such as housings, end caps, brackets, heat sinks, and non-load-bearing structural components — aluminum castings offer significant weight reduction. However, replacement is highly risky in environments involving high loads, high impact, high wear, or elevated temperatures.
5
What is the minimum order quantity? Do you support single-piece customization?
Yes. Single-piece prototype can be realized either by direct CNC machining from solid stock or via 3D printing. For production runs, the minimum order quantity is negotiable depending on the casting process selected. We offer flexible services to support product development and prototyping stages.
6
What surface treatment options are available for aluminum castings?
We offer a range of surface treatments, including electrophoretic coating (ED-coating), painting, electroless nickel plating, sandblasting, brushing, and powder coating. Recommendations can be made based on your product's application and service environment.
7
How about the production cost of low-pressure casting?
The production cost of low-pressure casting is "moderate to favorable", with the core being "moderate initial equipment investment and low comprehensive unit cost". It is particularly suitable for the production of medium and small-batch, high-precision castings, with a cost-performance ratio higher than die casting and superior to gravity casting (in complex part scenarios).
8
What is the difference between heat treatment and surface treatment in aluminium alloy casting?
Heat treatment is “bone-building”: solution & ageing (T6), or stress-relief anneal, re-arranges the microstructure to raise UTS/YS and stabilise dimensions. Surface finishing is “wardrobe”: done at ≤200 °C after machining, it deposits a corrosion-barrier, decorative or functional film.
9
What are the advantages of gravity casting?
Metal die = fast cooling: 15 % higher UTS/YS than sand-cast counterpart, denser microstructure. As-cast accuracy: CT 6–8, Ra 6.3–12.5 µm; Cpk-stable in long runs.
No sand: clean shop, easy robot pour, 70 % yield.
Tooling lifetime: 80–150 k shots; total part cost bottoms out at 1 k–50 k pcs/yr.

10
What are the types and specifications of die-casting machines?
Die casting machines have two main types: cold chamber die casting machines and hot chamber die casting machines.
In hot chamber machines, the injection chamber and plunger are immersed in the molten metal. In cold chamber machines, the injection chamber is separate from the holding furnace.
Die casting machines are available in various specifications, such as 200T, 400T, 650T, 900T, 1000T, and 1250T.

What is the principle of die-casting?
① The principle of die casting technology is a casting method in which liquid or semi-solid metal is filled into the cavity of a metal mold with a fixed shape and size at high speed under relatively high pressure, and then solidified into a casting.
② Die casting is a manufacturing process used to fabricate metal parts. how it works in simple words like:
Melt: Metal is melted until it's liquid.
Inject: This liquid metal is then forcefully injected into a pre-shaped, steel mold (called a "die") under high pressure.
Cooling & Solidification: The metal quickly cools down and hardens inside the mold, taking its shape.
Eject: Open the molds, and the finished metal part is pushed out.
It's a fast and efficient way to make large numbers of identical, complex metal parts with good detail.
