Green Sand molds casting
Green sand casting is a widely used metal sand casting process that uses wet, unbaked sand to make cavities and cores. The main advantage of green sand casting is that the foundry sand can be used many times after filtration, and after mixing with other clays or special minerals (such as: SiO2, kaolinite and montmorillonite), it can effectively improve the casting effect and surface finish requirements.
Supro MFG Sand Casting foundry is good at setting the gate and runner distribution system of green sand molds reasonably, so that the metal solution can be fully filled in the mold cavity until it solidifies, and the sand casting parts can maintain high quality and stability, and increase the economic competitiveness of the parts. .
resin Sand molds casting
This is a higher cost sand casting process, also known as shell molds casting. Relying on the resin-containing foundry sand, under the heating of the steel mold (the steel mold will incur higher investment costs), the resin will wrap the sand grains and become hard, resulting in a sand shell with a complex structure, and the inside is the molding mold of the product. cavity, the molten metal solution solidifies and cools in the sand shell, which can achieve very precise sand casting parts with fewer defects and sand holes, and the surface presents a very fine and uniform texture, which is widely used in auto parts, pipe joints, flanges, Sand casting of pumps, valves and other demanding iron and steel parts is now a very popular casting method in the foundry industry.
Supro Sand foundry has full pre-coated resin sand casting production line, more than 70% of orders for sand casting parts use this casting process. Choose Supro MFG and you won’t be disappointed.

Advantages of sand casting parts
Sand castings offer design flexibility
If your product is in the early stages of development and design, sand casting can offer great flexibility. Changes can be made to accommodate any minor changes in the design, so minor changes are very cheap.
At Supro MFG, we usually choose to use wooden casting molds for product development and casting testing process, which can not only reduce the investment of expensive molds, but also complete the mold manufacturing in a period of time.
Sand mold casting can design a variety of spliced mold shapes, and create casting parts for different application scenarios through different matching.
Moreover, the choice of materials is also variable. After reasonable selection of foundry sand and calculation of shrinkage, various metal alloys can be used to create the complex casting details you need.
In addition, the casting must have a draft perpendicular to the parting line, which cannot be avoided.
Dimensional Control and Consistency
Sand casting can produce a wide variety of different parts ranging in weight from less than an ounce to thousands of pounds. In Supro sand casting foundry, we generally control the size error within the range of ±0.5mm-1mm. According to the design and size requirements of the castings, we will reasonably set the most ideal mold plan, and keep it during batch casting. Stable consistency.
Surface finish for aesthetic vision
The surface finish of sand casting parts is mainly determined by factors such as foundry sand and mold, Supro MFG noticed that sand casting parts with uniform texture are required by many customers, we choose high quality foundry sand, as well as polished aluminum or steel The mold performs cavity molding. Sand cast parts have an aesthetically pleasing surface finish, and through secondary surface treatments, more functional applications can be enhanced such as: mechanical polishing, shot peening, painting, spraying, powder coating, electroplating (chrome, tin, etc.), Acid etched, anodized, galvanized and various other unique polyamide durable coatings.
Cost-effective sand casting parts
Compared with other casting processes, the casting process of sand casting parts is simpler, with fewer steps and lower mold costs. It is suitable for a variety of metal materials, and can quickly create complex casting structures and save expensive machining costs. The process can be applied to simple shapes as well as fairly complex castings, and can be used for all metals such as aluminum, cast iron, ductile iron, copper alloys (brass, copper and bronze), steel alloys, stainless steel alloys, and other complex metals.
