HULK Metal Lost Foam Casting Foundry

We will develop a complete production solution from the very beginning and strive to complete customer orders faster at less cost. The solution content will include delivery time, method, price, product production process, packaging, etc.

We will use the following process to pre-make samples and conduct all-round testing. We will send samples for you to test and then start mass production of your order after approval.

Because the order quantity is large, the lead time will be longer. However, we will allocate production resources to effectively shorten the lead time of orders by reasonably arranging order processes such as raw material procurement, Model production, Mold production, metal smelting, pouring, cooling, heat treatment, and other processes.

There are two ways to make the model used in lost foam casting: cutting ready-made foam plastic and using foam particles to foam the model in the mold. Appropriate model-making needs to be selected according to the specific requirements of the casting.

Spray a specific thickness of refractory material on the model. The coating can protect the foam model to prevent metal from penetrating the sand or adhering to the sand and can also reduce the surface roughness of the casting.

Place the special sandbox on a three-dimensional vibrating table, pour in the bottom sand, shake, and spread it evenly. Finally, put in the model coated with refractory material, continue filling with sand, and vibrate. Attach the membrane so that it is under negative pressure.

The metal smelting process is very complicated and will not be described in detail here. If you have castings that need manufacturing, kindly contact our sales managers. They will give you a complete solution.

Lost foam casting can also be divided into pressure, vacuum low pressure, vibration, and other casting processes. The pouring speed and process vary greatly depending on the process.

The cooled castings undergo sand shakeout and other cleaning processes before being polished, machined, and physically and chemically surface treated as required. This gives you the finished product.

Design exquisite packaging according to needs and provide a variety of packaging materials to give customers more options. Strictly managed warehouses can better preserve goods.

We have a freight consultation center that can help customers screen freight and logistics companies. Find better shipping options for faster delivery. After-sales service ensures the quality and quantity of goods and provides other free value-added services.
