Custom Aluminum Die Cast Components Service

Custom Aluminum Die Cast Components Service

Different components have different technical requests, tolerances requests, mechanical property requests, also with surface requests. Like how about salt spray testing, many components will assemble with other metal parts together, so how can we prevent any potential problem in assemble line when products delivered to the customer factory. china mold So reading drawing carefully before a quote will much better.

Our responsibility to let the customer know which kind of aluminum alloy will most fit for their components character, different aluminum alloy have different mechanical property, some alloy has good corrosion-resistant, some alloy strength than another one, some alloy fit for auto components, some alloy will have good cosmetic surface after finishing, particularly for chrome finishing aluminum die casting parts. Which production process will make components superior to standard, how can we solve cost for their project? This benefits each other. Anyway, the fine die casting solutions will get more inquiry.

Structure of sofa leg is quite simple for most high-pressure aluminum injection factory, does all of the aluminum die casting factory has impact simulation, just suppose 100kg person jump to the sofa. Impact at least 500kg. so your sofa leg impact resistant capability at least 800kg. how can we make die casting sofa leg strength and durable?no recycle material allowances, of course, strong aluminum injection tools are necessary. But we still need care when we order the sofa leg from a poor facility aluminum alloy dies casting company. die casting chair leg manufactory will reduce cost by small size machine to casting big sofa leg, how can they prevent deformation problem? just leave sofa leg in mold cavity more one minute, even no any air porosity problem when testing by x-ray. But actually, this is a very high risk for purchasers.

The aging problem will very serious when sofa legs get too much heat from the mold cavity, all die-cast manufactory knew how to prevent overheating problems during casting.In addition, we can also provide customized aluminum die cast mold service.

Custom Aluminum die cast mold service

3D and 2D products drawing from the customer, the step of mold flow simulation is necessary. To find any potential defects during casting. china mold For example, some parts have A surface and B surface requests. Particularly for nickel finishing die casting parts. No air porosity allowances, many parts will need second machining. Have air bulbs occur after machining. Some parts will have very strict tolerances in the same axle. This time JSCAST CAE software will offer a great solution. In fact, aluminum die casting mould manufactory designers need advanced CAE software to help their job, not only the experiences. DFM for customer confirmation, the step of raw material quality checking is very important, particularly the mold core material checking. Now material of H13, SKD61, 8407, 1.2344, DH-31 widespread use in Ningbo die casting mold manufactory. We not only checking the chemical composition and mechanical properties. The material pure standard is also very important for die casting tooling. Any impurity contains in the mold core will cause a crack problem after thousands of injection times, rough grinding, milling, and rough CNC machining before heat treatment. After heat treatment will take precision grinding and precision machining. In our pressure die casting mold workshop equipped with a high speeding five-axle machining center. EDM is widespread use in pressure dies casting tools production. This EDM machine's great advantage reduces machining cost and solved most complicated structure in HPDC dies, the disadvantage will get corrosion problem. So high standard EDM machines choose is critical. Remove oxidation material is a necessary step after EDM machining. Aluminum injection tooling cavity polishing. The roughness of the cavity also important for pressure die casting tooling injection times. The polishing direction should the same direction as mold opening.

Perfect mold design is important for mold injection times and superior quality casting components.

1 prevent molten aluminum alloy directly erosion-corrosion mold cavity. Over 70% of the crack problem caused by part mold overheating.

2 the injection speed and filling velocity control well when the casting gate located in the thick part.

3 for excellent air venting, the parting line better located at the end of the casting system.

4 let air have time escape from mold cavity before moving die and fixed die closed.

5 good parting line design should think about how to reduce deburr cost.

6 for strict concentricity casting parts, the products the same axle should locate in one cavity whatever female cavity or male cavity. Meet precision requests at the same time highest possible reduce second machining cost. 
In addition, we can also provide customized Aluminum Die Cast Mold Accessories.

Aluminum die cast with chrome finishing

Aluminum die-cast with chrome finishing

Chrome finishing aluminum die casting parts is much strict technical request, particularly for the super quality stand, zinc alloy parts are much easy to take chrome finishing after polishing. china mold How can we produce so nice chrome finishing parts by casting aluminum material not casting by zinc alloy? Some of our customers need their products light and same cosmetic surface like zinc alloy casting parts. The first step high-pressure aluminum casting molds air vent size need increasing bit than normal practice. Let air have enough time to escape from the aluminum injection mold. possible to select brass contain rate high aluminum alloy, we suggest aluminum alloy material like ADC10. ADC11, ADC12, A380, B390, 392, for your chrome finishing parts. Many aluminum die casting suppliers will mix recycle material during casting, this is obviously wrong. Any tiny impurity mix casting material is a disaster during polishing and chrome coating, in fact, even melting furnaces need clearing well before casting. Many die cast suppliers knew the basic chrome plating process. Normal practices are one layer brass coating+ one layer nickel coating +one layer chrome coating. Professional aluminum dies casting company will add another polishing step after one layer of brass coating. in our chrome finishing die casting field we call water polishing. The polishing wheel should soft and lubricated by water during polishing.In addition, we can also provide customized Aluminum Die Cast Mold Accessories.

How To Solve Casting Defects And Suggestion Tips

How To Solve Casting Defects And Suggestion Tips

1 cold flow

Increasing casting temperature, reduce filling time, add gate size, improve air venting condition. china mold Find the right aluminum alloy, silicon contains over 10% aluminum alloy will have good liquidity.

2 sinks

Different aluminum alloys have different shrinkage rates, find minimum shrinkage rate aluminum alloy for your casting products. Alloy aluminum shrinks less than pure aluminum, we suggest ADC14. The material of ADC14 Si contains 16%-18% Cu contains 4%-5%. And the same time reduces casting temperature and mold temperature.

3 blisters

Many blisters problems caused by ejector parts from the cavity, not the right time. To early ejector, parts will have not enough time solidification, keep products in mold cavity more few seconds.

Reduce mold temperature and check the mold temperature is equably or not, and prevent part mold overheating.

4 laminations

Poor mold rigidity, a problem caused by mold plate shake during casting, the pressure die casting mold base very important for die casting products quality, professional die-cast mold maker will seriously to handle every step in the quality die-cast not use QT550 or QT600 for your die casting mold base, most china die-cast mold makers will purchase S50c material for their aluminum die casting mold.

5 warping

First, we need to recheck the ejector pin to locate is the right place. Any deflect ejector will make casting parts a bending problem. Check stack-up products is the right way. Particularly for large and thin walls products. Like the die-casting aluminum light shell, the normal light shell was thin walls die casting parts.

6 shrink porosity

Reduce casting temperature, and looking the low melting point aluminum alloy, increasing injection pressure. Many aluminum dies casting manufactory casting big parts by small size cold chamber die casting machines. Before batch production Please Calculated part weight and analyze the project area.

7 cracks

Cracks problem caused by many cause. Check the mold first, check aluminum alloy chemical composition if mold has no any problem, any chemical ratio imbalance will make cracks problem, so control smelting furnace temperature stable is critical. At the same time increasing mold temperature.

8 gas porosity

Increasing air vent size, add filling time, let air have enough time to escape from the mold cavity. Recheck your lubricant spray is right or possible too much spraying.

Built up no dust powder coating line

Our company built up no dust powder coating line for our own die casting products this week. The outside processing powder coating is hard to control quality. china mold Not only the scratch problem, the most seriously is stick much tiny scrap on aluminum die casting components. We realized that the external fabrication plant not only powder coating for aluminum die casting parts, they also powder coating for stamping parts, sand casting parts, casting zinc parts, extrusion parts so on. Material from steel, zinc, bronze, iron, aluminum. Because different material need different treatment before coating, temperature in heat chamber for aluminum die casting powder coating better control 210 degree and 220 degree. Defects like orange peel, adhesion failure, bleeding always involve environment and temperature. Most pressure aluminum injection supplier knew environment is so important for powder coating quality control.


Air bulb in most case caused by casting, it will need check your aluminum injection mould quality, such as air vent design is right? Ask your local die casting mold supplier to check mold again. The die cast mold repair for free is common practices in Ningbo die casting industry.In addition, we can also provide customized Aluminum Die Cast Mold Accessories.
