Die Cast Process

Die casting is a process in which molten metal is forced into steel molds under high pressure or poured. The molds widely known as tools or dies as well are created using steel and are particularly designed for each project.And incorporates, in each part or component created, accuracy and repeatability. There are two primary types of die casting machines, hot chamber machines for alloys with low melting temperatures for example zinc and cold chamber machines for alloys with high melting temperatures, specifically aluminum. Meanwhile, with both machines, after the molten metal is injected into the dies, it rapidly cools and solidifies into the final component or part referred to as the casting.

Investment Casting Parts

Precision investment casting metal, utilizes lost wax casting process and produces near-net-shape parts. These metal parts oftentimes require little to no additional machining. Surface finish is also, much better than what is achievable through most other processes. Furthermore, the strength and durability of prototype or production cast metal parts makes them ideal for high wear applications. We ship high quality investment casted parts that provide outstanding benefits that are significantly reliable.

Investment Cast Process

Pattern configuration, lost wax casting pattern is created by injecting molten wax into an alloy die. Single molds or tree — like accuracy investment casting molds can be created for a large-scale high-volume run. The metal casting outer shell is built up through dipping the tree — like construction into ceramic slurry and then immediately coated with sand several times drying between each coat building layers. Inner cavity of investment cast is then dewaxed using high pressure and steam to force the wax out of the cavities and leaves the hollow tree — like construction of ceramic shell. Ceramic cavity is heated and cured, to prevent heat shock or ceramic shell from cracking once the liquid metal is poured into the ceramic tree — like construction shell. After the cast metal has cooled enough to handle, ceramic shell is removed from the tree and its components or parts by using a high impulse vibratory shaking. The components or parts are secondary machined if necessary, depending on the expectations of the components or parts and customer requirements.
