Types of Pre-coated Resin Sand Castings
Pre-coated Resin Sand Castings for Valves
Pre - coated resin castings in sand are high - quality castings that are utilized in a variety of valve application. The castings have a high dimensional accuracy, a high surface finish, as well as good mechanical properties that are important in ensuring that valves work efficiently in a variety of industrial environments.
Pre-coated Resin Sand Castings for Heavy Machinery
Pre-coated castings with high-grade silicon sand are usually preferred. Shape, form, as well as chemical quality, is preferred in case of the sand. In manufacturing parts that are machinery-intensive, high-roundness sand is preferred because it is more flowing in nature, which fills more thoroughly in complex mould.

(1) It has suitable strength performance. It can meet the requirements for high-strength shell core sand, medium-strength hot-box sand, and low-strength non-ferrous alloy sand.
(2) Excellent fluidity, good moldability of the sand core and clear outline, which can produce the most complex sand cores, such as water jacket sand cores such as cylinder heads and machine bodies.
(3) The surface quality of the sand core is good, compact and not loose. Even if less or no coating is applied, better surface quality of castings can be obtained. The dimensional accuracy of castings can reach CT7-CT8, and the surface roughness Ra can reach 6.3-12.5μm.
(4) Good collapsibility, which is conducive to casting cleaning and improving product performance.
(5) The sand core is not easy to absorb moisture, and the strength of long-term storage is not easy to decrease, which is conducive to storage, transportation and use.
Pre-coated Resin Sand Castings Procedures
1- Design and Make Patterns.
The pre-coated resin sand needs to be heated in the patterns, so metal patterns are the necessary tooling to make shell molding casting
2- Make Pre-coated Sand Mold
After installing the metal patterns on the molding machine, the pre-coated resin sand will be shot into the patterns, and after heating, the resin coating will be molten, then the sand molds become solid sand shell and cores.
3- Melt the Cast Metal
Using induction furnaces, the materials would be melted into liquid, then the chemical compositions of the liquid iron should be analyzed to match the required numbers and percents.
4- Pouring Molten Metal
When the melted iron meet the requirements, then they will be poured into the shell molds. Based on different characters of the casting design, the shell molds will be buried into green sand or stacked up by layers.
5- Shot Blasting, Grinding and Cleaning
After the cooling and solidification of the castings, the risers, gates or additional iron should be cut off and removed. Then the iron castings will be cleaned by sand peening equipment or shot blasting machines. After grinding the gating head and parting lines, the finished casting parts would come, waiting for the further processes if needed.
