Brass Precision Lost Wax Investment Casting Parts
Metal: Brass, Copper, Bronze Process: Lost Wax Investment Casting + Precision CNC Machining Weight: 5.80 kg Application: Flange
Brass Precision Silica Sol Lost Wax Investment Casting Parts from China company with CNC Precision Machining.
Brass Lost Wax Investment Casting Parts with CNC Precision Machining.
Copper and copper-based alloys can be formed into highly complex parts, making them ideal for the investment casting process. Constant cost fluctuations can make these materials very price sensitive, making waste very costly, especially when considering CNC machining and/or forging as a manufacturing process to produce your production part. Pure copper is not usually cast.
The process is suitable for repeatable production of net shape components from a variety of different metals and high performance alloys. Although generally used for small castings, this process has been used to produce complete aircraft door frames, with steel castings of up to 500 kgs and aluminium castings of up to 50 kgs. Compared to other casting processes such as die casting or sand casting, it can be an expensive process. However, the components that can be produced using investment casting can incorporate intricate contours, and in most cases the components are cast near net shape, so require little or no rework once cast.
Silica sol casting process is the main steel investment casting process of RMC investment casting foundry. We have been developing new technology of adhesive material to achieve much more economical and effective adhesive material to build the slurry shell. It is a overwhelming trend that Silica sol casting process replaces the rough inferior water glass process, especially for stainless steel casting and alloy steel casting. Besides the innovated molding material, the silica sol casting process has also being innovated to much steadier and less heat expanding.
