Die Casting Production Process
1.Order Receip

After the customer places an order, our engineers will discuss the mold structure and technical solutions with the buyer. We will work hard to avoid unnecessary errors in the mold, and provide our customers with the highest quality products.

2.Mold Design

When designing the mold, you should pay attention to make the structure of the mold and parts reasonable. The mold affects the shape, configuration, quality and stability of the product during the die casting process. Reasonable mold design is easy to manufacture and it can increase efficiency and production time.

3.Mold Flow Simulation

Professional mold flow analysis can pre-discover defects that may exist in the mold, saving the cost of trial and mold modification. For example, the optimization of the pouring scheme helps to determine the hot runner entry point and confirm whether there is “shrinkage”. Mold flow analysis can also combine the position of the wire, reduce warpage, improve cooling efficiency, shorten molding cycle, etc.

4.Mold Design Modification

Our company's professionals evaluate the mold design and make recommendations for modifications before finalizing and manufacturing. We will first confirm the manufacturability of a particular design and improve the mold if needed. Take advantage of a variety of foundry metals and processes to create products that meet the ultimate requirements.

5.Mold Production

Ningbo Ryan Machinery possesses 12 die casting machines, ranging from 180 ton to 800 tons. We have 37 horizontal and vertical machining centers, 35 turning centers. Various inspection equipment and software. We've also integrated in-process leak testing, and utilize vision systems for in-process inspection.

6.Mold Trial

Mold testing is the process of optimizing the new mold to be effectively manufactured.We will perform mold tests based on the information provided by the customer to ensure that the correct parameters are set on the injection molding machine, such as mold temperature, injection pressure, cooling time, holding pressure and holding time.

7.Mold Modification

If the mold is found to be further optimized before the final die casting, we will proceed with the mold modification step. Our mold shop is fully equipped to make most molds. Provide customers with a variety of customized molds.

8.Die Casting

The molten metal is pressed under pressure into a firmly locked metal mold cavity. It is then held by a powerful press until the metal solidifies. After the metal has set, the casting is taken out. Close the mold and lock it again for the next cycle.


Die casting trim dies cut or shear extra aluminum from die cast parts. When the trimming mold is forced down, excess metal in the part is cut away to provide a clean edge to the part.

10.Precision Machining

Ningbo Ryan Machinery Co., Ltd has in-house CNC machining shop to provide customer precision machining service after aluminum die casting and zinc die casting. Till 2019, Ryan has over 60 sets of cnc turning machines and four- axis cnc machine centers.


Cleaning is a different process performed to remove sand, scale and excess metal from the casting. Remove burnt sand and scales. Remove excess metal fins, wires, parting fins and gates. And finally test and check to see if there are any defects.


We will place the finished castings in a standard wooden box. Ensure that the product is not damaged. We can also provide customized packaging services according to the special requirements of our customers.
