Graphite is a commonly used material in plastic injection moulding due to its excellent thermal and electrical conductivity, high temperature resistance, and good wear resistance. Here are some standard graphite components used in plastic moulds:

Graphite cores: Graphite cores are used to create internal cavities in plastic parts. They are typically made from high-density fine-grain graphite, which provides good dimensional stability and excellent machinability.

Graphite ejector pins: Ejector pins are used to remove the finished plastic part from the mould. Graphite ejector pins are preferred due to their high temperature resistance and excellent wear resistance.

Graphite bushings: Graphite bushings are used to guide the ejector pins and prevent them from damaging the mould. They are typically made from a combination of graphite and metal, which provides good strength and durability.

Graphite heating elements: Graphite heating elements are used to heat the mould and maintain a consistent temperature during the injection moulding process. They are typically made from high-purity graphite, which provides excellent thermal conductivity and resistance to thermal shock.

Graphite cooling channels: Graphite cooling channels are used to circulate water or other coolants through the mould to cool the plastic and reduce cycle time. They are typically made from high-density graphite, which provides good thermal conductivity and resistance to corrosion.

Overall, the use of graphite components in plastic moulds can improve the performance and efficiency of the injection moulding process, leading to higher quality parts and reduced manufacturing costs.

Standard components for sliding materials include bushings, bearings, and other types of sliding components. These components are designed to be used in various types of machinery, such as automotive engines, industrial equipment, and medical devices.

The specific characteristics of oilless metal sliding materials can vary depending on the specific application and the materials used. However, some general benefits of these materials include:

Self-lubrication: Oilless metal sliding materials are designed to operate without the need for external lubrication, reducing the need for maintenance and the risk of contamination from lubricants.

Low friction: The solid lubricants in oilless metal sliding materials reduce friction and wear, resulting in longer service life and improved efficiency.

Corrosion resistance: Many oilless metal sliding materials are resistant to corrosion and can withstand harsh environments.

High load capacity: Oilless metal sliding materials are often designed to withstand high loads and can be used in applications where conventional lubricated bearings would fail.

Graphite bearings are commonly used in press die applications due to their self-lubricating properties, high temperature resistance, and ability to withstand heavy loads. In press die applications, where metal parts are being stamped or formed, the high loads and repetitive motion can cause rapid wear and tear on traditional metal bearings, making graphite bearings a more reliable and durable option.

Standard components for press die applications can include guide pins, bushings, and other bearings that support the die and help to guide it through the stamping process. Graphite bearings can be used in a variety of these components to reduce friction and wear and increase service life.

One key advantage of graphite bearings in press die applications is their ability to operate without added lubrication. The graphite in the bearing material provides a natural lubricating effect, reducing the need for external lubricants that can contaminate the stamped parts.

Graphite bearings also have excellent thermal properties, allowing them to maintain their strength and performance at high temperatures. This is important in press die applications, where the heat generated by the stamping process can cause traditional bearings to fail or degrade over time.

In addition to their self-lubricating and thermal properties, graphite bearings have a low coefficient of friction, which reduces the amount of force required to move the die and minimizes wear and tear on the bearing surfaces.

Overall, the use of graphite bearings in press die applications can result in improved efficiency, reduced maintenance, and increased service life of the press die components.

Independent production of raw materials: select high quality raw materials, bushings production, prevent defective products from the source to ensure oilles bearing bushings quality.

Strictly check the production process: monitor the production process, test and control the material composition in front of the furnace, and test the sliding bearings behind the furnace regularly to ensure that the material composition meets the needs of customers.

Regular national testing of finished products: regularly entrust national testing institutions to test material components and mechanical properties, and provide testing report.
