A sand casting is a cast part, which is produced by pouring liquid metal a mold made of a mixture of silica sand with addition of clay, moisture and some other additives (green sand) packed around an impression cavity shaped by a pattern). After the molding sand mixture has been packed and compacted around it, the pattern is withdrawn and molten metal is poured into the mold cavity which remains. After the metal has solidified and cooled, the casting is separated from the sand mold. The sand castings are easily recognized due its sand-like texture imparted by the sand mold. As the accuracy of the casting is limited by the green sand making process,Special Casting and Machining,there is always some sand residues on the surface of the castings to be removed. It is usually done by shot blasting process, where the casting surface is exposed to a stream of steel or iron shots, blasting its surface until the skin of oxides, silicates and other compounds will be removed. The molding sand going back into the sand processing plant will be remoistured and new additives mixed in. This means that the molding sand is reusable after adjusting its composition, replacing the elements lost in the thermal casting process. The pattern itself may be reused to produce new sand molds. This manual sand molding process that has been known for many centuries opened in the fifties of the twentieth century possibilities of automating the casting production process.

Sand castings may also be produced with molds made of sand that is bonded with materials other than moist clay. Many chemicals and mixture have been designed for this use. When these chemicals are used, they are collectively called “air set” sand castings to distinguish these from “green sand” castings.

Investment Casting samples

Investment casting technology, soluble glass technology and process.

Investment casting we called here is American style silicon gel process(with green wax and better sand) with very good smooth surface, tight tolerance, suitable for small part making widely used for stainless steel. It’s different with Russian style investment casting actually called soluble glass process(with white wax and rough sand)with relative rough surface, bigger tolerance, suitable for large part making more than 1.00KGS especially for carbon steel, alloy steel, sometimes also for ductile iron and grey iron..

Our engineers designed mould by PRO/ENGINEER, SOLIDWORKS, UNIGRAPHICS and simulation analysis software to be sure the quality and high efficiency before tooling machining.

Benefits of Shell Mold Casting:

1. Shell molding process offers better surface finish.

2 Shell molding process offers better dimensional tolerances

3 Shell Molding Process offers higher throughput due to reduced cycle times.

A heated metal pattern is covered with a mixture of sand and thermoset plastic. This causes a skin of sand mixture to adhere to the pattern. This skin is removed from the pattern to form the “shell mold”. The two halves of the shell mold are secured together and the metal is poured in the shell to form the part. Once the metal solidifies, the shell is broken.

The materials that can be used with this process are cast irons, and aluminum and copper alloys. Typical parts made with this process are connecting rods, gear housings, lever arms etc.

· The basic process for these molds is,

1. Create two mating patterns of desired shape.

2. Coat the molds with a shell (sand and binders, such as a resin) until desired thickness and other properties are obtained.

3. Cure the molds and remove the patterns.

4. The mold halves are mated and held firm while metal is poured.

5. The final part(s) is removed.

Shell molding process offers better surface finish, better dimensional tolerances, and higher throughput due to reduced cycle times.

A fairly high capital investment is required, but high production rates can be achieved. The process overall is quite cost effective due to reduced machining and cleanup costs.

The materials that can be used with this process are cast irons, and aluminum and copper alloys. Typical parts made with this process are connecting rods, gear housings, lever arms etc.

Alloys of aluminium are used in Die casting more extensively than alloys of any other base metals.
Die casting is especially suited to production of large quantities of relatively small parts. The more important reasons for using light metal casting are low weight, mechanical strength, stiffness and electrical properties. Other applications are e.g. components for the power transmission line in the vehicle industry and electronics industry.

Typical applications of die cast aluminium alloys include:

* · Alloy 380.0 - Lawnmower housings, gear
* · Alloy A380.0 - Streetlamps housings, typewriter frames, dental equipment
* · Alloy 360.0 - Frying skillets, cover plates, instrument cases, parts requiring corrosion resistance.
* · Alloy 413.0 - Outboard motor parts such as pistons, connecting rods, and housings
* Alloy 518.1 - Escalator parts, conveyor components, aircraft and marine hardware and lit tings.

With die casting, it is possible to maintain close tolerances and produce good surface finishes. Die castings are made by injection of molten metal into metal molds under substantial pressure. Rapid injection and rapid solidification under high pressure combine to produce a dense, fine-grain surface structure, which results in excellent wear and fatigue properties. Our factory have Large spectrum of die casting machines (280T - 1600T),it can produce Variety of alloys available to meet in house production requirements and to provide quality custom-made die-casting parts for other industries
