Steel Investment Casting

Product Description

Our company employs a lot of practical experience and experienced designers. Under their guidance, our workers can make top-level things. We can assure you that if there is any problem, our company will be happy to send engineers to repair and replace the damaged castings for free. We are able to supply 50,000 pieces per month for castings for trains and railways.

The manufacturer must first create a master or wax pattern. This form is an exact replica of the part to be produced, and in some cases it is the original prototype that can be hand carved, machined, or produced by injection molding. All defects must be removed from this model before performing all other steps to ensure that it is an exact replica of the required part. The master mold is then mounted on a wax stick called a gate using a heated metal tool. In some cases, several such patterns can be attached to a runner to form a cluster called a tree. Once the mold is in place, the investment mold is applied. The ceramic slurry must be applied to the entire wax pattern. This is accomplished by repeatedly immersing the gate or tree into a finely reduced melt until the desired thickness is reached, or by fixing the gate in the flask and pouring the mold around it.

The investment is then dried and hardened in an oven or oven, which also causes the initial wax form to melt and flow out leaving the desired mold. Additional heat is required to remove all residue and moisture. This also preheats the mold, allowing the incoming molten metal to coat more uniformly before cooling in the mold. After pouring the metal into the mold, it is cooled, and the hardened investment shell is removed by a medium jet vibration, hammer or solvent to reveal a seamless final product.
