What are the problems and regulations in the design of lost foam castings?

If you are engaged in the production level of the foundry industry, you should not be unfamiliar with casting parts. High-quality Ductile Iron Lost Foam Investment Casting Screw Nut are very important parts in the foundry industry and have been used by us all the time. Its design materials are easily available, generally various shape-memory alloys. Today, let’s take a look at the design problems and regulations of high-quality aluminum alloy die-casting parts, let’s find out together!

The design of castings generally belongs to the design of the box. The first thing to consider in the design of the box is the placement of the parts in the box and their relationship with the external parts of the box. For example, the shape of the box is defined according to the two specified contour lines of the CNC lathe. and specifications, in addition to the following issues should be considered:

1. Meet the requirements of compressive strength and bending stiffness. For box parts with a very high load, achieving compressive strength is a key issue; but for most boxes, the primary criterion for evaluating performance is bending stiffness, because the bending stiffness of the box not only affects the routine work of transmission system parts , And the lost foam casting manufacturer also affects the precision of the component work. The model selection of Kuaiyiyou automation technology for castings is included in Baidu.

2. Heat dissipation performance and thermal deformation problems. The friction and heat of the parts in the box will change the viscosity of the grease, which will affect its lubricating performance; the temperature rise will cause thermal deformation of the box, especially the thermal deformation and internal stress of the uncoordinated distribution of temperature, which will have a negative impact on the accuracy and compressive strength of the box. Greater hazard.

3. Product structure design is effective. For example, the distribution of support points, the layout of the ribs, the design of the perforated part, the buckle structure, etc. are all conducive to improving the strength and bending stiffness of the box.
