Friction press is a type of screw press driven by friction, also known as a double disc friction press. The production of press machines in metal forging workshops utilizes the contact transmission between flywheels and friction discs, and works based on the principle of relative motion between screws and nuts. Due to its versatility in use, as well as the advantages of simple structure, installation, operation, and auxiliary equipment, and low cost, it is widely used in stamping workshops, forging workshops, and die forging workshops in industries such as mechanical manufacturing, automobiles, tractors, and aviation, and can also be used for punching. Friction press is also a building materials machinery widely used in the dry pressing production of ceramic tiles, ceramic tiles, and refractory products.

    Copper sleeve, also known as copper bearing, requires lubrication of the bearing with oil. It is made of various copper alloys for lubricating mechanical parts. It is an important component of various large and heavy machinery. The main materials are 1 ZCuSn6Zn6Pb3,ZCuSn5Zn5Pb5, Can be used to manufacture wear-resistant parts such as bushings, gears, worm gears, etc. that work under moderate loads and speeds. 2. ZCuSn10P1 is a typical tin phosphorus bronze with high hardness and wear resistance. It can be used to manufacture parts that work under heavy loads, high speeds, and high temperatures, and are subjected to strong friction, such as connecting rod copper sleeves, gears, worm gears, etc. 3 ZCuAl9Mn2,ZCuAl9Fe4, Aluminum bronze has high strength, high density, and stable chemical properties. Commonly used in valve bodies, worm gears, nuts, pipe fittings, etc. 4. ZCuZn25Al6Fe3Mn3 high-strength aluminum brass has the highest strength among special brass. It has high strength, high hardness, high wear resistance, moderate plasticity, and good corrosion resistance. Therefore, it is used for casting high load wear-resistant weights on heavy machinery
