The general process of casting production is to make molds, melt raw materials, pour, cool, clean, and finishing to finish products. Many casting processes are derived from this process. This answer briefly summarizes this content. Kindly search for other content on the website to fully understand it.

The general process for making sand casting molds is to make two upper and lower sandboxes, make a casting pattern, mix sand and binder, fill it into the sandbox with the pattern and vibrate it, take out the pattern, put it in the sand core and close the box. The method or whether to remove the pattern needs to be determined according to the casting process. For example, the pattern of investment casting is taken out through high-temperature evaporation, while the pattern of lost foam casting does not need to be taken out. We will introduce it in more detail below.

Our foundry is equipped to offer a diverse range of high-quality casting processes. We specialize in sand casting, which allows us to create a wide variety of metal parts with complex geometries. Whether it's for small-scale prototypes or large-volume production runs, our sand casting process ensures consistent results.

We also excel in die casting. This process is ideal for producing precision parts with smooth surfaces and tight tolerances. Using state-of-the-art die-casting machines, we can handle different types of metals, particularly aluminum and zinc alloys, for applications in the automotive, electronics, and consumer goods industries.

In addition, we provide investment casting services. This is the go-to process when creating intricate and detailed components. Our investment casting team has extensive experience in producing parts for the aerospace, jewelry, and medical device industries, where precision and surface finish are of utmost importance. With our comprehensive range of casting processes, we can meet the unique needs of every customer, regardless of the project's size or complexity.

Castings and forgings are significantly different in production, materials, workpiece shape, internal structure, mechanical properties, applications, etc. Here only a relatively simple comparison is made between them. Kindly contact us if you have a workpiece and you are not sure which process is more suitable for production.

To ensure dimensional accuracy, proper mold design is essential. The mold should be designed with allowances for shrinkage, as most metals shrink as they cool and solidify. Using high-quality mold materials that can withstand the heat and pressure of the casting process without deforming is also crucial. In die-casting, the precision of the die itself plays a major role. Regular calibration and maintenance of the casting equipment, such as pouring systems and injection units in die-casting, are necessary to ensure consistent and accurate operation. Additionally, post-casting machining operations can be used to further refine the dimensions of the part to the required tolerances.

Aluminum is extremely popular. It has a low density, good corrosion resistance, and high thermal conductivity, making it suitable for a wide range of applications, from aircraft parts to cookware. Iron, especially cast iron, is another commonly cast metal. It has excellent castability and high compressive strength and is often used in engine blocks, pipes, and machinery parts. Copper and its alloys, such as brass and bronze, are also widely cast. They offer good electrical and thermal conductivity as well as attractive aesthetic properties, which is why they are used in electrical components, decorative items, and musical instruments.

Our mold fees are quoted individually according to the complexity of the product structure. Usually, they are charged once for the first order, and no further payment is required for subsequent orders, which also reduces the long-term procurement costs for customers. 

1. Castings' drawings (2D or 3D) If there are no drawings, samples can be provided

2. Material (if not on the drawing)

3. Quantity

4. Delivery terms

Our colleagues will give you a better quote after understanding your needs more deeply.

Sure. We have a variety of flexible payment and free methods for mold fees. Of course, there is a premise for this, which requires your purchase quantity to reach a certain value. Kindly contact us to learn more about how to waive mold fees.

We need to decide based on the complexity of the casting, the quantity you require, the quantity of a single delivery, and many other factors. For a specific delivery period, our sales manager will lead the service team to develop a solution that satisfies you based on your requirements.

T/T(For big orders, 30-90 days can be acceptable), L/C, for other methods please contact our sales manager.

You only need to give us the following information to get a simple quote:

Sure. The cost of mold production is fixed. As the order quantity increases, the proportion of mold cost in the overall product cost will become smaller and smaller. Our customers will place additional large-volume orders after receiving samples and confirming that they are qualified.

Yes. We provide one-stop services, including casting, CNC machining, heat treatment, surface treatment, such as painting, electroplating, sandblasting, etc. Customers no longer need to connect with multiple suppliers, saving time and management costs, and ensuring that delivery time is more controllable.

We have passed the ISO 9001 quality management system certification and are equipped with complete quality inspection equipment, which can carry out:

• Chemical composition analysis (spectrometer)

• Mechanical property test (tensile, impact)

• Dimensional inspection (CMM three-coordinate)

• Non-destructive testing (such as X-ray, magnetic particle inspection)

Each batch of goods can provide a corresponding test report, and if necessary, it also supports third-party certification.

The dimensional tolerance of our casting products can usually be controlled within the CT7-CT9 level, and the surface roughness can reach Ra 6.3-12.5μm (depending on the type of process, such as precision casting or sand casting). For critical size parts, we can also carry out machining to meet higher precision requirements.

The regular production cycle of our casting samples is 15 to 25 working days. The specific time needs to be comprehensively evaluated based on the complexity of the product structure:

Simple structures (such as basic geometric shapes, regular surfaces): Sample production can usually be completed in about 15 days.

Complex structures (such as special-shaped surfaces, multiple cavities, fine lines): The cycle needs to be extended, about 20 to 25 days, because additional adjustments to the mold parting line or additional process steps are required.

Yes, we support return, replenishment, and exchange services. Any products with quality defects will be dealt with in the best possible manner after being confirmed. We will actively deal with any of your questions. For more than 20 years, the feedback we have received from our customers on our products has been consistently positive.
