Graphite Mould

Feature:

1. Thermal stability: According to the quench acute thermal using conditions of graphite crucible, we will specially design the production procedure, so as to ensure the reliability of product quality.

2. Corrosion resistance: Even and fine basic design will delay the erosion of crucible.

3. Impact resistance: Graphite crucible can bear high thermal impact, so any process can be carried out.

4. Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially its index of acid resistance., and will prolong the service life of graphite crucible.

5. High heat Conduction: High content of fixed carbon ensures the good heat conduction, shorten the time of dissolution, and remarkably reduce the energy consumption.

6. Control of metal pollution: The component of material under strict control will ensure that graphite crucible will not pollute the metals when dissolving.

7. Quality stability: The process technology of forming under high pressure and quality guarantee system will fully ensure the stability of quality

Q:Do the hot bending toughened film with graphite mould. How do you deal with the pressure on the surface?
The easiest way to make coins naturally produce an oxide layer is to put clean, fat free coins into 10% of two sulfite solution for 10 to 20 seconds. Rinse off and dry with a soft cloth. Even after soaking two sulfite solution before copper will be issued a delightful bronze luster, and generally will not be corroded.
Q:What are the electrodes on the die?
Because the melting point of copper is 1083oC, and the melting point of graphite will appear in 3400oC. Graphite electrode can bear more machine setting conditions. These settings calculate the rate of metal removal and the amount of graphite loss. If the electrode material needs to be strictly controlled, the graphite electrode can be placed in a non - wear state (loss less than 1%) during rough machining. But the copper electrode is not used. Graphite electrode is easy to process. Graphite milling speed than other metal processing fast 3-4 times, and does not require additional manual processing.
Q:Why use graphite material for 3D curved glass mould?
Excellent thermal conductivity and conductivityLow coefficient of linear expansion, good thermal stability and thermal shock resistanceChemical resistance is difficult to react with most metals
Q:Why should graphite column be used as solid lubricant in mould guide sleeve?
Graphite can be used as a solid lubricant, but most of them use ordinary oils as lubricants. Graphite is used here as a lubricant. The possible reason is to prevent the oil from polluting the products.
Q:How to make the graphite mould and how to form the graphite mould?
Graphitized productsSuch products include graphitized electrodes, graphitized anodes, graphitized blocks, high-purity, high-strength, high-density graphite, etc..These products are made of petroleum coke or asphalt coke as the main raw material. At last, they are treated at high temperature over 200 degrees Celsius to convert amorphous carbon into graphite. Its characteristics, C > 99%, gray powder 0.5%, conductive and electrothermal good, good corrosion resistance; production process complex and long cycle, generally 40~60 days.
Q:Where can I sell graphite mould?
Mold is widely used in industrial production of basic process equipment, mold industry is the basic industry of the national economy. In modern industrial production, stamping, forging, die casting, extrusion, plastic injection or other processing methods widely used in product parts, and forming mold of supporting the blank forming product in accordance with the requirements of the parts. A variety of tools and products used in our daily life and production, to the machine base body shell, the first embryo to a small screws, buttons and various household appliances, all have a close relationship with the mold. The shape of the mold determines the shape of these products, and the quality and accuracy of the die determine the quality of these products. In recent years the rapid development of mold industry, graphite materials, new technology and the increasing of the impact of the mold factory mold market, becoming the first choice of graphite mold making materials with good physical and chemical properties.
Q:Plastic mold: several commonly used die repair method
Mold plays a very important role in modern industry, and its quality decides the quality of product directly. To improve the precision and service life of mould, shorten the mould manufacturing cycle, many enterprises urgently need to solve technical problems, but in tooling process often collapse angle, deformation, wear, or even broken failure form. Therefore, the repair of the mold is also necessary. There are many ways to repair dies, such as EDM, argon arc welding, laser overlaying and brush plating. The argon arc welding repair uses the arc which is continuously sent between the welding wire and the workpiece as the heat source, and is welded by the gas protection arc ejected by the welding torch nozzle. At present, argon arc welding is a common method and can be applied to most major metals, including carbon steel and alloy steel. Metal inert gas welding for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloy, due to low prices, is widely used in mold repair welding, but the disadvantages of the welding heat affected area, solder joints, the precision mold repair has been gradually replaced laser welding repair. Brush plating brush plating technology is the use of a special DC power supply equipment, power supply electrode plating, brush plating anode as the anode; power supply is connected with the workpiece, as the cathode. The brush plating pen is usually made of high purity fine graphite block as anode material
Q:How many times can a graphite hot bending die be used at most?
Depends on the factors of service life of the largest bending die to do Katie carbon mold use materials, such as graphite materials made by Gao Chungao density bending mould, as long as the use of attention and maintenance, the general use of a few years is no problem, the second is to work well not rough.
Q:What can graphite be used to make dry batteries?
The use and properties of the material are closely linked. Because the graphite soapy, can reduce the friction between the material, can be used as a lubricant, and the high temperature resistance for high temperature lubricant. Have good conductivity can be used as electrode.
Q:We mainly do brass processing, using graphite mold life is too short, please advise
The longer service life of die material made of, but the price is higher.
We engaged in producing carbon and relevant carbon products and crystalline flake graphite. We are faithful and powerful with strength in technology and quality. Meanwhile, we can offer you the most reasonable price and the fast delivery. Welcome to have a visit to our company, or send your kind enquiries.
