Process
The first step in creating high precision castings is the manufacturing of the tool which upon wax injection will produce a replica part that is to be manufactured.The next step in our Investment Casting process is wax injection. The tool is injected with a specially formulated wax product and a designed replica of the part is achieved.
Our wax department is equipped with a variety of wax injection machines ranging from 12 ton to 50 ton presses including two 25 ton automatic units.
Upon completion of injection the wax patterns are transfered to our assembly area where they will be assembled and attached to the parts trees. Shown below are a few of our wax assembly stations where wax patterns are carefully cleaned and inspected by highly trained operators.
Next, the parts are taken through our dipping process where coats of ceremic material are applied using a fully automatic process. The robot performs flawlessly no matter how many times the process must be repeated. The parts are loaded back onto a conveyer system where they dry and harden.
Our conveyer system is capable of handling 400 molds at all times.
After drying, the invested ceremic shells are taken to our autoclave dewaxing system which quickly removes the wax pattern material from the ceremic molds. Then the molds are placed in the oven and pre-heated to temperatures above 1800 degrees Fahrenheit prior to accepting the liquid metal.
Prior to pouring a complete chemical analysis is preformed.
Next, while the molds are still hot out of the oven, steel is poured into the molds.
The parts then undergo a cooling process and then each part is removed from the parts tree.
Each part is put through a 100% inspection process prior to shipping.
Shown here is a pallet of completed castings to be accepted by the customer.
