'laboratory use'

Ultrasonic hand held welding systems for manual assembly operations, such as spot welding, staking and inserting. The instrument's small size makes it ideal for small series applications and laboratory use. A further operation is spot welding and staking of large parts which require a large degree of mobility of the welding equipment.

Ultrasonic welding (USW) is a welding technique that uses ultrasonic vibrations of high frequency to weld the two pieces together. It is most commonly used to weld thermoplastic materials and dissimilar materials. A high frequency (15 kHz to 40 kHz) ultrasonic vibration is used to join two plastic pieces together. The high-frequency vibration generates heat energy at the interface of the two pieces and melts the material. The melted materials fused with each other to form a strong weld on cooling and solidification. The typical frequency used is 15, 20, 30, 35 or 40 kHz.

We offer a wide range of vibration welding machines for small and large interior and exterior automotive parts as well as a variety of industrial parts. A vibration welder with a high efficiency single phase output amplifier ensures precise and high-quality welding. During the welding process, linear scale is used for precise lift table and melt control. Auto tuning time of 4 seconds, user-friendly touch panel and communication, real-time resonance frequency tracing, auto fixture recognition sensor, and specialized software have all been used. With superior welding strength and quality they are suitable for the automotive, home appliance and plastic appliances industries.

In order to fuse thermoplastic components with rotationally symmetric joints, the spin welding process uses heat generated by rotational friction at the joint line. The spin welding machine applies pressure axially while rotating one part against its stationary counterpart, and the resulting friction generates heat that melts the two pieces together.

Hot plate welding is a type of thermal welding used to join thermoplastics. To melt the two surfaces to be joined, a heated tool is placed against them. The heat source is then removed, and the surfaces are pressed together.

Heat Staking is a joining technology used to join two or more parts, at least one of which is made of plastic. The process uses heat and force to melt and deform the plastic material over a set period of time. The heated plunger with a defined profile cavity descends on the plastic stud. To achieve the desired profile, force is applied to the stud. It is used to join dissimilar materials and large parts, such as car door trims, air ducts, and the instrument panel in a car.
