Ultrasonic plastic welding machine mould

Ultrasonic plastic welding machine mould is an important tool for the application of ultrasonic welding technology in the field of plastic processing. The following is a detailed analysis of the ultrasonic plastic welding machine mould:

First, the mould type and material

Ultrasonic plastic welding machine mould according to different application requirements and welding objects, can be made of a variety of materials. Common materials include:

Aluminium alloy: such as 7075, 2024, 6061 and other models, with good hardness, thermal conductivity and toughness, suitable for different requirements of the welding scene. Among them, 7075 aluminium alloy has high hardness and is commonly used in vibration systems and HORN manufacturing; 2024 aluminium alloy has good toughness and strong thermal conductivity and is commonly used for general fusion welding of plastic products; 6061 aluminium alloy is suitable for bottom mould manufacturing or lower output HORN.

Titanium alloy: very high toughness, good thermal conductivity, high hardness, but the cost is more expensive, usually used for continuous vibration timing or the performance requirements of very high occasions.

Other materials: such as SCM8, 45C medium carbon steel, SS41 iron, epoxy resin, PUT resin and Bakelite, etc. Each of these materials has its own characteristics and is suitable for different welding needs and material types.

Second, the characteristics of the mould

Customised design: Ultrasonic plastic welding machine moulds usually need to be customised according to the shape, size and welding requirements of specific products to ensure welding effect and product quality.

Efficient welding: Using the heat and pressure generated by ultrasonic vibration, the plastic material in the contact surface quickly melts and fuses to achieve efficient and fast welding process.

Environmental protection and energy saving: no need to use glue and other adhesives, which reduces the pollution to the environment and saves production cost at the same time.

Third, the mould parameters

Amplitude parameters: Amplitude is one of the key parameters in the ultrasonic welding process, which determines the vibration amplitude of the welded end face and welding effect. Different materials have different amplitude requirements, need to be adjusted according to the specific material and welding requirements.

Frequency parameters: ultrasonic welding machine frequency is also an important factor affecting the welding effect. Common frequency 15K, 20K, 28K, etc., different frequencies for different materials and welding scenes.

Fourth, the application scene

Ultrasonic plastic welding machine moulds are widely used in plastic packaging, auto parts, electronic products, medical equipment and other industries. For example, in the plastic packaging industry, ultrasonic welding machine moulds can be used to make all kinds of plastic boxes, plastic bottle caps sealing welding; in the auto parts industry, it can be used for automotive interior parts, lamps and other plastic parts welding processing.

V. Maintenance and upkeep

In order to maintain the good performance and prolong the service life of the ultrasonic plastic welding machine mould, it is necessary to carry out regular maintenance and repair. This includes cleaning the mould surface, check the mould wear and tear, adjust the amplitude and frequency parameters.

To sum up, ultrasonic plastic welding machine mould is an indispensable and important tool in ultrasonic welding technology. Through customised design, efficient welding, environmental protection and energy saving features and advantages, it provides efficient and reliable welding solutions for the plastic processing industry.
