Product Description
Custom Metal Casting Services
Metal casting is the process of pouring molten metal into a cavity mold and then cooling it to form a solidified part. Depending on the method you choose, metal casting can achieve very high production rates with little to no secondary operations.Custom Casting Considerations
Factors to consider for casting services include:
Part Quantity/Production Batch Size
Tooling affects the time and cost of a production run. Each casting method has its own advantages and disadvantages, so choosing the best type of casting process is difficult
Determining the size of your production run can help you find the right foundry. Shops often specialize in high-volume or low-volume production projects
Casting Materials
The type of material selected for a casting project depends on the project requirements
Common materials for metal castings include aluminum, steel, stainless steel, copper, zinc, magnesium, nickel, and various alloys
Die Casting
Die casting is a four-step process that involves forcing molten metal into a mold cavity under high pressure, resulting in a precise and highly repeatable casting method.
Investment Casting
Investment casting is one of the oldest known methods of forming metals. In this process, a mold is formed around a wax pattern, which is burned off as the molten metal is poured in.
Permanent Mold Casting
Permanent mold casting uses reusable graphite molds and is ideal for making high-precision parts. Because graphite molds can withstand indefinite use, accurate castings can be produced over and over again.
Sand Mold Casting
There are several types of sand casting, including green sand casting, dry sand casting, dry sand casting, and self-hardening sand casting. Each method has different advantages.

Common casting materials are:
Stainless steel
Used in aerospace, defense, and other applications where corrosion-free parts are required. Has high tensile strength and excellent aesthetic value. Other applications include food storage, medical equipment, and plumbing components.
Carbon steel
Carbon steel produces wear-resistant precision parts. Low cost and easy to machine. Can be heat treated to increase its ductility. Used in mining, and industrial industries.
Aluminum
Lightweight and excellent corrosion resistance. Has high electrical and thermal conductivity. Recyclable. Common aluminum investment castings include automotive castings, radiators, valves, medical devices, and more.
Nickel alloys
Universally used materials. Has excellent corrosion resistance and can withstand high temperatures. Ideal for demanding applications such as oil, gas, medical, aerospace, and defense industries.
Copper alloys
Have similar strength and a variety of mechanical properties to steel. High ductility and corrosion resistance. Common applications include gears, pumps, bearings, plumbing fixtures, and more.
1. How to get a quote?
Detailed drawings (PDF/STEP/IGS/DWG...), including quality, delivery date, materials, quality, quantity, surface treatment and other information.2. Can I get a quotation without drawings?
Can your engineering team draw for my creativity? Of course, we are also glad to receive your samples, pictures or detailed size drafts for accurate quotation.
3. Can you provide samples before mass production?
Of course, the sample fee is necessary. If possible, it will be returned during mass production.
4. What is the delivery date?
Generally, the sample lasts for 1-2 weeks and the batch production lasts for 3-4 weeks.
5. How do you control quality?
(1) Material Inspection - Check material surfaces and approximate dimensions.
(2) First inspection of production - ensure
critical dimensions in mass production.
(3) Sampling inspection - check the quality before delivery to the warehouse.
(4) Preshipment inspection - 100% inspection by QC assistant before shipment.
6. After sales service team
If you have any problems after receiving the product, you can provide feedback through voice call, video conference, email,etc.Our team will provide you with solutions.
