Custom Aluminum die cast mold service
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 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.
Perfect mold design is important for mold injection times and superior quality casting components.
Prevent molten aluminum alloy directly erosion corrosion mold cavity. Over 70% crack problem caused by part of mold over heating
The injection speed and filling velocity control well when casting gate located in thick part
For excellent air venting, the parting line better located the end of casting system
Let air have time escape from mold cavity before moving die and fixed die closed
Good parting line design should think about how to reduce deburr cost
For strict concentricity casting parts, the products same axle should locate in one cavity whatever female cavity or male cavity. Meet precision request at same time highest possible reduce secondly machining cost.
