Precision machining VS gravity casting process

Most aluminum gravity cast parts should be post machined to obtain much precise features. However most of such machining can't be referred as precision machining for example drilling, tapping, simple turning and milling. The precision machining so called here are those done by precision machines such as machining center , cnc machine and assisted by precision lab equipments like projector, and cnc. Precision machining can be most expensive one of all the manufacturing processes.

Aluminum gravity casting process can achieve comparatively complicated geometrical features, furthermore the gravity cast stock always have better mechanical property than those made by aluminum sand casting and high pressure die casting, therefore aluminum gravity die casting process is for providing raw stock for post precision machining. Reciprocally precision machining can get an aluminum casting to be much precise, with increasing added value. Generally speaking, precision machining is a key important process for an aluminum gravity casting foundry.

To be a professional aluminium gravity casting foundry, we have introduced a complete line of aluminium gravity casting machines,and post machining machines such as machining center, CNC lathes, and other necessary machines. Along with training and organizing an active and functional manufacturing team, we focus on introduction of advanced automatic machines to reduce labor intensiveness,improve production capacity and quality steadiness, so as to create added value for our customers.

Featured advantage of aluminum gravity casting over precision machining

Generally speaking, precision machining is the most expensive manufacturing process. Precision machining from a profile stock such aluminum plate to a complicated aluminum part can be even more expensive than machining from an aluminum casting stock. That is the featured advantage of an aluminum gravity casting. The gravity casting process can achiever a part's geometrical features much precise than aluminum sand casting process. It can save lots of machining for the unmating feature or less critical features.

Besides, precision machining always takes much more time to get a finish part than aluminum gravity casting process does. Precision machining is a material removing process, but it can only remove few material at one cutting which as we called is feeding. In order to achieve better surface quality , the feeding value should be under a limited range. However gravity casting process can obtain the finish part at one shooting or pouring. After solidification, the casting is finished. Without slight cutting and trimming ,the aluminum gravity cast product can be used as a finish part readily.
