Product Description

Casting is one of the basic processes of modern equipment manufacturing. The casting process can be divided into three basic steps, namely casting metal preparation, mold preparation, and casting processing. Casting metal refers to the metal material used for casting castings in the production of castings. It is an alloy in which metal elements are the main components and other metals or non-metal elements are added. It is usually called casting alloy, which mainly includes cast iron, cast steel, and cast non-ferrous alloy. As a professional casting company, ECTN provides our clients with advanced metal casting services such as low and high-pressure aluminum casting, custom aluminum casting, custom brass casting, permanent mold aluminum casting and etc.

Die Casting
The product uses die-casting process to complete the blank, CNC machining and polishing treatment, suitable for auto parts.

Gravity Casting
The product is a casting product, which is used to fix the support of the driven shaft. The surface is not machined and has no holes and cracks.

Processable Materials for Casting
Stainless Steel
Carbon Steel
Alloy Steel
Zinc Alloy
Aluminium Alloy
Carbon Fibe
Spring Steel

Advantage of Casting
It Can Produce Parts With Complex Shapes, Especially Blanks With Complex Cavitie
Wide Adaptability, Metal Materials Commonly Used In Industry Can Be Cast, From A Few Grams To Hundreds Of Tons.
The Shape And Size Of The Casting Are Very Close To That Of The Parts, Reducing The Amount Of Cutting, Which Is Non-cutting.
It is Widely Used
40%70% of agricultural machinery and 70%80% of machine tools are castings.

Casting FAQs
Casting Cracks
1. Usually, the metal solidifies too fast at this place, resulting in casting defects joints;

2. Cracks caused by high temperatures.

The solution: Use low-strength investment materials, reduce the casting temperature of the metal as much as possible, and do not use alloys with low ductility and brittleness.

Easy To Crack When Die-casting Thin-walled Products
If this problem occurs, it may be due to material problems or poor mold opening or improper selection of process parameters. Try to control the proportion of waste not to exceed 30%. The mold retention time should not be too long, about 3s per mm of wall thickness, and ejection delay is not allowed. Long, generally 0.5-2s.

Metal Splashing During Die Casting
Reinstall the mold; increase the clamping force and adjust the die-casting machine to keep the movable and fixed mold mounting plates parallel to each other; add a support plate on the movable mold to increase the rigidity of the sleeve plate.

Why Can't The Inner Processing Of Aluminum Die-casting Hole Exceed 0.25mm
In order to be suitable for die casting, people add a lot of silicon to the aluminum alloy used for die casting. When the aluminum alloy condenses in the mold, the silicon will float on the surface to form a layer of silicon film that is very hard and wear-resistant. Some OEM designers use this feature to directly design the inner surface of the die casting hole as a bearing surface. This silicon surface layer is generally only 0.2 to 0.9 mm thick. With too much processing, the life of the bearing surface will be shortened.

Unclear Marking During Casting
1. The mark on the mold is not clear enough the reason for the mold;

2. The markings on the mold are not clear. You can analyze whether the particle size of the following molding sand is fine enough and whether the strength is high enough;

3. The refractoriness of the mold and coating is not enough.

4. Another factor that is easily overlooked is the casting location of the casting mark. When determining the casting position, try to keep the casting mark on the bottom or side to avoid being on the top surface.

About Us

We manufacture parts here in China covering different fields from a simple stamping to complicate CNC machining. We struggle with what to call ourselves since we are not a traditional machine shop, seller, or a metal parts service bureau. Regardless, once you work with ETCN, you will call us a trusted and professional partner. Currently, we have a CNC machining center, automatic lathe, grinding machine, meter lathe, milling machine, Drilling center, and stamping machine, etc. Our capabilities can include our own job of machining process such as stamping, lathe work, wire cutting, and so on, also extended process like deburring, assembly, shot and sandblasting, heat treatment, surface plating, and powder coating/painting. A raw process like hot/cold drawn, cast, and forging can be also integrated with long experience. We have the expertise to qualify our components before distribution ensuring the required quality to our customers. Our excellence of high quality low cost is what we are known for and is the key to our growing success for many years. We serve our customers with a high level of what the customers' concerning quality, delivery, and valued service.
