ing refers to the use of clay bonded sand for casting, molding materials production is the process method has a long history, is also the most widely application scope.
With a long history dating back to thousands of years ago;
Its application scope, can be said that there is no place not all over the world.
Next, explain the dongguan foundry casting process for you.
Foundry is poured into the molten metal in the mould cavity, cooling and solidification and get products after production methods.
In automobile manufacturing process, there are a lot of parts is made of cast iron blank which accounts for about 60% by weight of the whole vehicle, such as cylinder block, transmission box, steering gear housing, rear axle shell, brake drum, all kinds of support, etc.
Usually USES the sand mold manufacturing cast iron pieces.
The raw material is given priority to with sand, the sand mold and binder, water, etc.
Sand mold material must have a certain bond strength, in order to be shaped into the required shape and can resist high temperature molten iron scouring and won't collapse.
In order to make the sand mold shape consistent with casting the shape of the cavity, must first be made from wood model, referred to as a wood pattern.
Hot molten iron after cooling will be smaller, therefore, the size of the block model needs to be in the casting according to the shrinkage rate increase, on the basis of the original size need machining surface corresponding thickening.
Hollow castings made from sand core, and the corresponding core block (
With wooden, can double cavity mould.
In manufacturing sand mold, want to consider how sand box up and down to remove the wooden separately, also consider the molten iron from where flow, how to fill the cavity in order to get high quality castings.
After sand mold is made, can casting, and the molten iron is poured into the sand mold cavity.
When pouring, hot metal temperature in 1250 ~ 1350 degrees, melting temperature is higher.
Then pass desanding, repair, and grinding process, such as to become a qualified casting.
