The cost of gravity die casting is relatively high.
The design and manufacturing process of gravity casting molds are complex, requiring high-precision design and high-quality raw materials, all of which lead to high costs. Specifically:
Design cost: The design work of gravity casting molds is very important. When designing, it is necessary to consider multiple factors such as the gate, riser position, weak points, size and mechanical properties of the mold. The design process takes a lot of time and effort, so the design cost is high.
Raw material cost: Gravity casting molds usually use steel as raw material, and the price of steel is relatively high. Steel of different qualities will affect the quality and weight of the mold, which in turn affects the cost. High-quality steel will increase the cost of the mold.
Production efficiency and quality requirements: The service life of gravity casting molds has a direct impact on production efficiency and cost. If the mold life is short and needs to be replaced frequently, it will increase time and cost. Therefore, gravity foundries have strict requirements on the quality and life of the mold.
Mold type selection: The procurement cost of metal molds is relatively high, and although the procurement cost of wooden molds is low, it will incur maintenance costs when they are not used for a long time or mass production.
Of course, gravity casting has corresponding suitable products. Only the following industries are suitable for gravity casting, and foundries also recommend gravity casting:
Automotive industry: used to manufacture key parts such as engine cylinder blocks, cylinder heads, gearbox housings, exhaust pipes, and wheel hubs.
Aerospace: used to prepare key parts such as large turbine blades and aircraft engine housings.
Machinery manufacturing: commonly used to manufacture parts for various mechanical equipment, such as machine tool beds, workbenches, turbines, automobile brakes, and automobile steering gears.
Electronics industry: used to manufacture housings, radiators, and other parts of some electronic equipment, such as computer cases and mobile phone radiators made of aluminum alloy.
Architectural field: used to manufacture aluminum alloy frames and accessories for building doors, windows, curtain walls, and other components, as well as various metal castings for architectural decoration, such as door handles, hinges, and decorative lines.
Hardware tools: such as handles, heads, and other parts of hardware tools such as various wrenches, pliers, and hammers.
Home appliance industry: aluminum housings of some home appliances, such as air conditioner outer casings and washing machine inner drums.
Energy industry: used to manufacture gas turbine blades and nuclear power equipment and more.
It should also be noted that gravity casting is not suitable for thin-walled parts, which is a feature of the process.
