  • CNC Precision Machining
    Precision CNC Machining Factory CNC Precision machining is the process of cutting metal parts to make them fit the end user’s applications and functions. Much of modern machining process are carried out by computer numerical control, CNC, in which computers are used to control the movement and opera
  • How to distinguish the quality of shaft coupling?
    The quality of the coupling is fundamental, and the image of the coupling is also important.The image mainly refers to the shape of the coupling, which is the bare state, such as surface roughness, surface treatment (painted state, blackened state or electroplated state)
  • The role of shaft coupling
    Shaft couplings are mechanical parts that are mainly used to connect two rotating shafts in mechanical transmission to achieve the transmission of torque or rotation angle; they can also be used for equipment protection of safety devices.
  • What are the ways to fix the coupling?
    1. Fastening bolt type: This is a traditional fixing method with low cost. However, this will directly contact the bolt with the shaft, which may cause damage to the shaft or difficulty in disassembly.2. Clamping type: This type uses the power of countersunk head bolts to shrink the slit and tightly
  • Shaft coupling development trend analysis
    Shaft couplings are increasingly used in precision machines controlled by servo systems such as machine tools and semiconductor manufacturing machinery. In these fields, unlike general manufacturing machinery, the coupling must require that its output has a high followability relative to the input.
  • Densen Group's first badminton competition in 2020 was a complete success
    Densen Group, as China top investment casting company, held a badminton competition. In this competition, we harvested sweat and happiness. Throuth the covid-19 virus,we know the importance of health.After keeping health,we can work harder in the future to bring customers more effective Interests.

  • The lightweight material of the shaft coupling-carbon fiber
    Carbon fiber is a fibrous carbon material. It is the most commonly used and most important reinforcement of advanced composite materials. It has high specific strength, high specific modulus, high temperature resistance, fatigue resistance, creep resistance, and low thermal expansion coefficient.
  • Types of Molds for Aluminum Casting
    There are many types of molds for aluminum casting that are used in casting molten aluminum into different shapes and forms. Some molds are temporary, and others are permanent and can be used repeatedly. These same types of molds are also used for many different metals and alloys besides aluminum.Sa
