Product Description

1. Products Description:

Precision Investment Casting Modified Car Parts/Truck Parts/Forklift PartsInvestment casting is an ancient manufacturing process that has been used for centuries to create complex, high-precision metal parts. The process begins with the creation of a wax model, which is then covered with a ceramic slurry to form a shell.Once the shell has hardened, the wax is melted and the molten metal is poured into the cavity. Once the metal has solidified, the ceramic shell is removed using a vibrating hammer and the resulting part is calibrated, among other things using our unique multi-dimensional straightening technique.Investment casting also produces less waste than traditional methods such as sand casting or die casting, making it more cost effective and environmentally friendly.

2. Production Process
-Mold designAccording to customers' drawing, our engineer will finish the mold design.And then make the mould according to the design. -Wax injectionThe wax is being injected by the machine. Wax design of the desired castings is produced by injection molding. -Assembly treeThe patterns are attached to a central wax stick, to form a casting cluster or assembly tree.-Shell makingThe shell is built by immersing the assembly in a liquid ceramic slurry and then into a bed of extremely fine sand. Up to 6 layers may be applied in this manner. The shell will be dry in each layer making.-DewaxingOnce the ceramic is dry, then heating. The wax will be melted out. The melted wax will be flow out from the shell.-CastingIn the conventional process, the shell is filled with molten metal by gravity pouring. As the metal cools, the parts and gates, sprue, and pouring cup become solid casting.-Knock-outWhen the metal has cooled and solidified, the ceramic shell will be broken off by vibration or a knock-out machine.-Cut offThe parts are cut away from the central spruce using a high-speed friction saw.-GrindingAfter the casting was cut off. The casting pouring part will be ground carefully.-Inspection and post treatmentThe casting will be inspected by the inspector as per the drawing and quality request. If there are unqualified parts. It will be repaired and inspected again.-Finished castingAfter surface finishing operations, the metal castings become identical to the original wax pattern.-MachiningThe casting blank will be machined by CNC according to customers' drawings-TestingThe finished parts will be tested by the professional inspection engineer. -Packing The qualified parts will be packed according to customers' request.3.

7.FAQ

1. Are you a manufacturer or a trading company? Do you have your own factory?

We have a casting factory and a machinery factory, and also we have cooperative plants to provide other services, such as plating and coating.

2.What material can you do?

We make investment casting with carbon steel ,alloy steel, stainless steel and other material.

3. Can you make casting according to our drawing?

Yes, we can make investment casting parts according to your drawing, 2D or 3D. If the 3D model can be supplied, the development of the tooling can be more efficient. But without 3D, based on 2D drawing we can still make the samples properly approved.

4. Can you make casting based on our samples?

Yes, we can make measurement based on your samples to make drawings for tooling making.

5.How many days will samples be finished?
A:Generally, the mould and sample will be finished within one month.

6. What's your quality control device in house?

We can do many tests to control the quality in all directions. Such as dimension inspection,chemical composition analysis (spectrum analysis),mechanical property testing,X-Ray inspection,dye penetrant inspection,magnetic powder inspection,metallographic inspections and so on
