What kind of steel is the mold used for casting aluminum, and what is the best mold steel for alumin

In China, 3cr2w8v is commonly used for die-casting molds.

The temperature of the cast aluminum mold is high, and if you use ordinary materials, it will not take long for the surface of the mold cavity to crack. Only the use of heat-resistant steel 3Cr2W8V can ensure the finish of the mold surface for a long time.

The mold used for casting aluminum is 3cr2w8v die-casting mold steel.

135-2435-1833 plate round steel 3cr2w8v3cr2w8v domestic die steel.

Standard: GB T 1299-1985

Characteristics and scope of application: Hot work die steel is a commonly used die-casting die steel, which has high strength and hardness, good cold and heat fatigue resistance, and good hardenability, but its toughness and plasticity are poor. It is suitable for making punches and dies that are not subject to impact load under high temperature and high stress, such as die-casting molds, hot extrusion dies, precision forging dies, non-ferrous metal forming dies, etc.

Dear, hello, I am happy to answer for you, what is the best die steel for aluminum stamping die Answer: D2 die steel is the best for aluminum stamping die. 1. Aluminum is easy to stick to the mold and will strain the mold.

It is necessary to choose the mold steel model with good wear resistance, such as: D2, die steel with high wear resistance, micro-deformation cold work die steel, air hardened tool steel, high carbon content, high chromium content, heat treatment hardness up to steel can be used to manufacture cold work die steel with large cross-section, complex shape, high impact force and high wear resistance, such as silicon steel sheet punching die, cold cutting scissors, trimming die, etc. 3. DC53 special steel belongs to cold work die steel.

DC53 special steel is a new type of cold work die steel that improves SKD11, and its technical specifications are contained in the Japanese Industrial Standard (JIS) G4404. It overcomes the weakness of SKD11 in high temperature tempering hardness and toughness, and will fully replace SKD11 in the field of general and precision molds. The working part --- alloy tool steel, such as:

CRWMN, CR12, CR12MOV, SKD11, D2 non-working part--- carbon steel, such as: 45, A3

May I ask you, how much is the temperature appropriate before production? How much is appropriate to maintain in production?

The selection of aluminum alloy die-casting mold materials should be based on the size of the mold, the complexity of the structure, the requirements of the service life of the mold, and the cost of the mold. Aluminum alloy die-casting mold material selection, generally there are 4 kinds of material selection schemes.

Summary. The mold core is made of hot work die steel. The domestic grades are 3Cr2W8V, 4Cr5Mosiv, and the imported grades are H11 and H; SKD61, DAC, DH-31, W302 and so on.

What material is used for general aluminum alloy die-casting molds.

The mold core is made of hot work die steel. The domestic grades are 3Cr2W8V, 4Cr5Mosiv, and the imported grades are H11 and H; SKD61, DAC, DH-31, W302 and so on.

The thickness of my product is 50 mm, the length is 100 mm, and the width is also 100 mm, so what material is used for the cavity to ensure that 20,000 molds will not crack.

With H13 material, hundreds of mold cavities have cracked at all corners.

Spring port film. Die casting molds for such thick products can be used with spring steel will not crack.

No. It is not the plane that cracks, but the cracks at the bottom of the corners of the product.

Each corner is less than 2,000 molds, and all cracks are made with spring steel to ensure that they will not crack.

The pouring mold belongs to the high-temperature heat-resistant abrasive tool, which is commonly used to make high-temperature heat-resistant abrasive tool steel, and the traditional steel type for making the casting mold in this type of steel is semi-high-speed steel, and the specific grade is 3Cr2W8V. In addition to this, there are H13, H11, Y10, HM-3, etc.

Sand casting: Sand casting has a wide range of adaptability, small parts, large parts, simple parts, complex parts, single pieces, large quantities can be used. Sand molds are more refractory than metal molds, so materials with higher melting points, such as copper alloys and ferrous metals, are also used in this process.

The mold used for sand casting is generally made of wood, commonly known as wood mold. In order to improve the dimensional accuracy, it is also common to use aluminum alloy molds or resin molds with a long service life. Although it has improved, it is still much cheaper than molds for metal mold casting, and the advantages are particularly prominent in the production of small batches and large parts.

Summary. Generally, cold work die steel can be used, which mainly depends on the workload and speed and frequency of the mold.

Aluminum parts are prone to high temperatures, so the hardness of the punch is required to be above 60°, at least SKD11 material or above, and it is best not to use D2 or even worse punches.

You asked the best, according to the aluminum is easy to stick to the mold, the adhesive layer, or the object will damage the mold with the movement of the die, so you should choose the mold steel with high hardness and better wear resistance, DC53, Caldie or higher grade materials.

What material is selected for the convex and concave die of aluminum plate forming die?

What material is selected for the convex and concave mold of 1mm thick aluminum plate forming die?

The general cold stamping die structure can be used to achieve the purpose, and the die can be designed to be lower than the middle D60mm part. 05mm, the upper die adopts an elastic pressing plate, and the cutting edge of the punch is inverted. When working, the elastic pressing plate first presses the workpiece, and the punch is pressed down to form.

This ensures the flatness of the workpiece.
