What Is Aluminum Die Casting

What Is Aluminum Die Casting

Aluminum die casting is a versatile manufacturing process for producing engineered metal parts by forcing molten metal into a mold form due to high-pressure systems. china mold It’s a manufacturing process for producing precise, accurately smooth, and textured metal parts. The parts with the highly valued combination of lightweight and superior strength. The aluminum die-casting machines range from 18-0T to 2000T so that we can produce parts with a few grames to more than 40 pounds.

Even aluminum die casting parts can with different surface treatments, such as powder coating, plating, e-coating,chrome plating, and bright polishing, with a beautiful and protected outer layer.

Why choose aluminum die casting

Aluminum with advantages such as lighter weight, durable and so on, aluminum also is one of the most popular materials for producing functional parts and prototypes. It also offers impeccable corrosion resistance, thermal and electrical conductivity, and also maintains dimensional stability even in high temperatures and harsh environments.

Since this material with a high melting point, so aluminum die casting process is the best way to cast aluminum parts

In a detail of this metal casting process, high pressure is used to force molten metal into the mold cavity. So aluminum die casting requires to use of aluminum die casting mold, which with a mold cavity, or cavities, which is created using two hardened tool steel dies that are machined into a specific shape, are machined into a special shape.

Compared to CNC machining, aluminum die casting reduces the amount steps required for production and prototyping, resulting in lower manufacturing costs. It also ensures a high-quality surface finish and precise dimensional consistency.

This technique is especially advantageous in small and middle-size casting parts, it's widely used in industries such as automotive, lighting, medical and more.

Advantage of aluminum die casting

As a lightweight metal, the most popular reason for utilizing aluminum die casting is that it creates very lightweight parts without sacrificing strength. Aluminum die-cast parts also have more surface finishing options and can withstand higher operating temperatures than other non-ferrous materials. Aluminum die-cast parts are corrosion resistant, highly conductive, have good stiffness and strength-to-weight ratio. The aluminum dies casting process is based on rapid production that allows a high volume of die casting parts to be produced very quickly and more cost-effectively than alternative casting processes. Aluminum die casting has become the favored option for buyers worldwide.

Characteristics and Advantages of Aluminum Die Castings include:

·Have a good stiffness and strength-to-weight ratio

·Based on rapid production

·Allows a high volume of die casting parts to be produced very quickly

·Is more cost-effective than alternative casting processes

·Lightweight and Durable

·Good strength-to-weight Ratio

Customer Visit For Aluminum Die Cast Shift Fork

Customer Visit For Aluminum Die-Cast Shift Fork

Raw material quality is very important for the PDC shift fork. How about your normal material hardness? The normal die-casting aluminum alloy hardness only controls 78HB-85HB. china mold This is not enough. So looking at the quality raw material is critical for your project. The material of ADC14 and R14 is popular for casting aluminum shift fork. But whatever ADC14 or R14, normal hardness only around 80HB before treatment. Ask your local material supplier increasing hardness around 95HB-100HB. But how about their treatment technical and facility? Just as you know contradiction between hardness and fragility.

We will calculate parts weight and analyze project area for fit die casting machines, 280 cold chambers die casting machines are powerful enough for ordinal parts in the same project area and weight. We are one gear shift fork manufactory in china. Experiences told us this is a high risk for die casting aluminum shift fork when we produce by low power machine. We quite understand some pressure die casting companies thinking, they try to reducing energy emission, But for high-pressure casting shift fork is totally wrong. Ask your local aluminum die casting molds company to produce two-cavity mold, casting by 400T cold chamber die casting machine. Eliminate air and impurity is a necessary step during casting, so it will need two melting furnaces. Casting temperature control around 680 degrees.

Aluminum die cast with precision machining

Aluminum die cast with precision machining

Good machining fixture design will provide high efficiency and guarantee strict tolerances at the same time. How many pieces one machining fixture? We suggest putting six or eight parts when your parts size from 6CM-12CM. china mold Clamping by air cylinder is tight enough. Some die casting producers in china still clamping parts by screwing, this is low production efficiency. Products will deformation if screwing too tight, cutting knife will break when screwing bit loose. Perfect machining fixture designer will take into consideration many facts. For example how to make machining operator put in and take out much convenient. Which part on casting parts fit for clamping, many parts on casting body not fit for clamping, such as the thin wall, surface with casting die joint, surface with air vent, surface with protrudes ejector pin. Looking at the thick wall and flat part for clamping is the right choice. Many die casting tooling suppliers forget to indicate the draft angle for the machining workshop. it will make serious mistakes during machining fixture design. This is why the aluminum die casting mold manufactory should provide all detailed information on DFM.

Machining scrap wipe off by air gun should high frequency, any scrap remains on the fixture will damage parts surface, also will impact tolerances. Why some aluminum scrap stick on machining fixture so tight? Because cooling lubrication to sticky. To find the right cooling lubrication is more important than looking at a powerful air gun. Many die casting manufactory in china select the wrong cooling lubrication, some too sticky, some too watery.

Machines custom design to meet the especially machining requests. CNC machine customization is very popular in the custom pressure aluminum casting industry. Particularly for large quantity products machining. Discuss between aluminum injection molds team and machining department at soon when we get an inquiry from the customer. Ten years before the big project from the auto industry attached us but the price almost no any profit. We drilling hole by brother CNC drilling and milling recombination machining center. The brother CNC drilling and milling recombination machines have a good reputation for their fast production among the aluminum die casting factories. But the production capability still limited. 1.5cm diameter, depth 7.5 cost almost 2 minutes. Assemble line in customer factory was very anxious for our production capability. We purchased the custom-made deep hole drilling machines from Mitsubishi after an urgent meeting. 2 minutes drill 5 deep holes. The tolerances control much strict compare to the machining center. This is greatly enhanced production capability. Now the Mitsubishi deep hole machines have a very good reputation among the china aluminum die casting man.In addition, we can also provide customized Aluminum Die Cast Mold Accessories.

Aluminum die cast with powder coating

Aluminum die-cast with powder coating

Powder coating for aluminum parts not so difficult compare with chrome finishing aluminum die casting parts in many people's minds, this is right.china mold But why still need strict control for high-quality powder process. First, we need to select the right powder material, we suggest Dupont for your components finishing material because this material has excellent adhesiveness. We need to clear the powder coating chamber again before every batch powder coating, Although we have no dust powder line. Because every batch powder coating will have a different color. Any remaining color in the last batch will mix the new production line. This will seriously destroy new batch product quality. Particularly for aluminum PDC housing or large surface area like a die-casting aluminum light shell. many outdoor light fixture manufacturers knew how to use DuPont outdoor powder material for their corrosion-resistant light shell. Different aluminum die casting components with different sizes and structures, good hanging will prevent parts crash and scratch, good hanging will fit aluminum components bit tight and keep space one part to another part. For example, the die-cast TV mount and die-casting aluminum bracket will very easily scratch during powder coating, because many dies casting factories in china have no powder coating line in the house. Anyway, die casting manufactory should build their own no dust powder coating line for a super quality reputation.In addition, we can also provide customized Aluminum Die Cast Mold Accessories.
