Goal Sure machining co.,ltd was founded in 2001, located aluminum die casting mold hometown Ningbo. Year 2007 company total investment 50million yuan, on 30 acre land build up 2000 square meters pressure die casting mold workshop, 3500 square meters pressure aluminum casting products workshop, 600 square meters aluminum die casting tools accessories workshop.
3D and 2D products drawing from customer, the step of mould flow simulation is necessary. To find any potential defects during casting. For example, some parts have A surface and B surface request. Particularly for nickel finishing die casting parts. No any air porosity allowances, many of parts will need secondly machining. Have air bulb occur after machining. Some parts will have very strict tolerances in same axle. This time JSCAST CAE software will offer great solution.in fact all aluminum die casting molds manufactory designer need advanced CAE software to help their job, not only the experiences. DFM for customer confirm, 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 property. The material pure standard also very important for die casting tooling. Any impurity contain in mold core will caused crack problem after thousands 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 mould workshop equipped with high speeding five axle machining center. EDM is widespread use in pressure die casting tools production. This EDM machines great advantage reduce machining cost and solved most complicate structure in HPDC dies, the disadvantage will get corrosion problem. So high standard EDM machines choose is critical. Remove oxidation material is necessary step after EDM machining. Aluminum injection tooling cavity polishing. Roughness of cavity also important for pressure die casting tooling injection times. Polishing direction should same direction with mold opening.
Different components have different technical request, tolerances request, mechanical property request, also with surface request. Like how about salt spray testing, many components will assemble with another metal parts together ,so how can we prevent any potential problem in assemble line when products delivery to customer factory. So reading drawing careful before quote will much better.
Our responsibility to let customer to know which kind aluminum alloy will most fit for their components character, different aluminum alloy have different mechanical property, some alloy have 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 standard, how can we solved cost for their project. This is benefit each other. Anyway the fine die casting solutions will get more inquiry.
Die-cast aluminum is a type of aluminum in which the metal is released from the mold cavity under high pressure. During the die casting process, the metal is hardened and produces the desired shape. Aluminum die-casting can use hot chamber process or cold chamber process.
Aluminum die-casting is considered a reusable non-consumable technology that can produce die-cast aluminum of different shapes, sizes and thicknesses. The die-casting process can produce various shapes with precision and attractiveness.
Aluminum die casting is now considered an industrial process used to manufacture aluminum for sale or as part of machinery or any other commercial or industrial production. This is currently the simplest process, because aluminum is melted in a designated mold to produce the required size, shape, and thickness. This process is crucial in creating metal parts with specified details and quality.
There are many reasons why aluminum is the most common non-ferrous metal found in the world. As a light metal, the most popular reason for using aluminum die casting is that it creates very light parts without sacrificing strength. Aluminum die castings also have more surface processing options and can withstand higher operating temperatures than other non-ferrous materials.

Chrome finishing aluminum die casting parts is much strict technical request, particularly for super quality stand, zinc alloy parts is much easy take chrome finishing after polishing. How can we produce so nice chrome finishing parts by casting aluminum material not casting by zinc alloy? Some our customer need their products light and same cosmetic surface like zinc alloy casting parts.
First step high pressure aluminum casting molds air vent size need increasing bit than normal practice. Let air have enough time escape from 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 supplier will mix recycle material during casting, this is obvious wrong. Any tiny impurity mix casting material is disaster during polishing and chrome coating, in fact even melting furnace need clearing well before casting. Many die cast supplier knew basic chrome plating process. Normal practices is one layer brass coating+ one layer nickel coating +one layer chrome coating. Professional aluminum die casting company will add another polishing step after one layer brass coating. in our chrome finishing die casting field we call water polishing. The polishing wheel should soft and lubrication by water during polishing.
Powder coating for aluminum parts not so difficult compare with chrome finishing aluminum die casting parts in many people mind, this is right. But why still need strict control for high quality powder process. First we need select right powder material, we suggest Dupont for your components finishing material, because this material have excellent adhesiveness.
We need clearing powder coating chamber again before every batch powder coating, Although we have no dust powder line. Because every batch powder coating will have different color. Any remain color in last batch will mix new production line. This will seriously destroy new batch products quality.
Particularly for aluminum pdc housing or large surface area like die casting aluminum light shell. many outdoor light fixtures manufactory knew how to use dupont outdoor powder material for their corrosion resistant light shell. different aluminum die casting components with different size and structure, 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 easy scratch during powder coating, because many die casting factory in china have no powder coating line in house. Anyway die casting manufactory should build their own no dust powder coating line For super quality reputation.
Good machining fixture design will provide high efficiency and guaranteed strict tolerances at same time. How many pieces on one machining fixture? We suggest put six or eight parts when your parts size from 6CM-12CM.
Clamping by air cylinder is tight enough. Some die casting producer in china still clamping parts by screwing, this is low production efficiency. Products will deformation if screwing to tight, cutting knife will broken 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 part on casting body not fit for clamping, such as thin wall, surface with casting die joint, surface with air vent, surface with protrude ejector pin. Looking thick wall and flat part for clamping is right chose. Many die casting tooling supplier forget indicate the draft angle for machining workshop. it will make seriously mistake during machining fixture design. quality reputation.

Company of LKM, ASSAB, UDDEHOLM, LK, BOHLER hade branch company not far away from us, this is great advantage for us to purchase high quality stand steel for our aluminum die casting molds, and high quality raw material for our custom die casting parts. The standard pressure die casting molds base from LK is precision and durable.
A Good die casting supplier and high pressure aluminum die casting technical man should knew, different aluminum alloy have different application. Because different chemical composition have different mechanical property. Select the right aluminum for your die casting solutions is important step for excellent products. Many die casting supplier in china neglect chemical composition in their jobs few years before.Material of A360 with same chemical composition with material JIS ADC3 and EN AB-43400, this kind material have good corrosion resistant and strength property, this kind material is good for cycle wheel, boat propeller. Material of ASTM A413 is same chemical composition with material JIS AD1 and EN AB-47100. The property of A413 fit leakage request products, is good for dental facility, instrument panel, auto dash board. Application for thin wall and complicate structure custom die casting components. Material of A380 with same chemical composition with ADC10 and EN AB-46200. This kind material is popularly used in aluminum tv mount manufactory, because this kind material have good crack and heat resistant capability.Accessories of die casting aluminum cookware also have excellent performances with this material. Now many aluminum alloy die casting company select A380 for their custom pressure casting project. Material of A380 is good application for gearbox housing, air cylinder header, auto engine base bracket, telecommunication housing. Material of ASTM A383 with same chemical composition with ADC12 and EN AB-46100. Many die cast company select ADC12 for their abrasion resistant request products. A...
A Experiences die casting mold factory will realized how important overflow and air vent location, normal overflow and air vent will located in parting line, is easy for air escape from die casting tooling. Why some die cast mold supplier will located air vent and overflow in thin area and thick area, because the thin or thick part will much easy contain impurity and gas. The rich experiences die casting mould company will knew how to prevent any defects when air vent separate with aluminum parts
