Features of Aluminium Die Casting machining
Aluminium casting molding can make very complex parts, it retains high precision and good dimensional stability.
it has more cost-effective than aluminium machining. If your parts need mass production and high rates of production, Aluminium casting solution should be suitable.
Aluminium casting parts need having even wall thickness of wall from 0.5mm-5mm, neven thickness will tend to cause some issues.
Good aluminium casting part comes from good mold, high quality casting mold is expensive.
Aluminium casting molding can get better surface. you can get cosmetic surface by post surface treatment
Aluminium casting parts is 5-20 times more expensive than plastic injection molding.
The life of Aluminium casting mold have just 30,000-60,000 shots(The mold will have unsightly network cracks raised as thermal fatigue of the mold surface).
How to design a good aluminium casting part, you should consider its function, performance, appearance, precision and cost......
and follow some guidelines before starting project:
1: Select suitalbe Al material. You should clearly know properties of material according to parts application designed, such as corrosion resistance, strength-to-weight-ratio, conductivity.
Then select correct aluminium material. there are some generic material, A380, A360,413.
2: Appearance Requirement: End customers always have an appeal for aesthetic-looking products, so that will hold much significance an external aluminium casting part
has a good apprearance. A good finishing also can provide additional protection for extreme weather conditions.
3: Assembly demand. Usually an aluminium casting component need to be assembled with other components with different joining ways.Fastening,Threading, insert molding......
You must provide detail assembly information to our engineers, because assemby mean that some features of an aluminium casting compoent has to match other part, the assembling features will need
some extra performance for accuracy, smoothness of the surface,strength......
4: Consider aluiminium casting molding tolerance, post machining, so you should save some allowance in your part design. Aluminium casting parts tolerance comes from 2 factors, one factor is
uneven shinkage, when the casted parts is ejected from mold, the parts will shrink, the shrinkage is about 1.0055, but it isn't very even, the shrinkage tolerance is about 0.0005-0.001. the other factor is machining tolerance of mold,
it is about 0.05 MM.
5: Caculate cost of parts and timeline. The cost of an aluminium casting part is composed of 3 main parts. The first part is weight, it account for 30%-40% of cost. The second part is post machining,it account for 40% of cost.
The third part is surface treatment, it accout for 20-30% of cost. If the weight of your part is 0.2KG, the total cost is about $5-9 per piece.The timeline is composed of 2 main parts. The first part is making mold and confiming samples,
it usually needs 40-70 days. The second part is production, it usually needs 15-40 days. If you need a quotation for your aluminium parts, could you please contact us as sales@viewmold.com you can get our feedback in 24 hours.
6_1: Wall thickness design, Engineers should adopt uniform wall as even as possible. Uneven wall will cause more casting defects and poor casting quality, designer shoud avoid it.
Thicker wall will cause more cooling time and more shrinkage, if it is too thick, the part will occur some small holes on the area, the thick wall
also add weight of part . Thinner wall will cause short shot for unfilled defect. Recommended scope of wall thickness is 0.5MM-6MM, the best scope is 1.5 MM- 3MM. Before our design team start designing mold, our engineers will check
degree of uniformity of wall of part with advanced softer. Once we find thickness issue, our projecter will communite it with our customer and avoid potential risk.
6_2: Design draft. The draft is very important design feature for an aluminum casting part, draft mean retavie surface tapering to the moving direction of mold, it also is perpendicular to the parting line of the mold. draft design
is necessary,if there is no draft on part design, it will cause more defects, if when opening mold or eject the part, no draft surface will be damaged, if the damage is very serious, no draft surface feature will stick on the mold. The draft angle is as big as
possible, recommended minimum angle is 0.5 degree.
6_3: Fillets & Radii, Fillets and Radii design can improve remarkably strength of part, any size fillets is acceptable, there is no recommended size, but fillets and radii feature should maintain wall thickness even.
6_4: Ribs
6_5: Insert
6_6: Thread Forming
6_7: Undercut
6_8: Hole and Window
6_9: Slot & Groove design
6_10: Pressure Tightness
6_11: Boss
6_12: Text
6: Lightweight Design
6: keep sharp edges to a minimum.
