VSP 405-14

The VSP 405-14 vibration welder was designed and manufactured using state-of-the-art technologies (3D CAD, CNC).
This technology is used for welding thermoplastic parts that have complex geometric shapes or when the material itself cannot be welded using traditional  technologies (ultrasound – hot plate).
The vibration is circular. Unlike conventional vibration welders, vibration is obtained through the   displacement of a specially shaped shaft. This is very important because it allows the client to make the necessary fixturings. The mechanical and electrical solutions available create optimal operating conditions with ample adjustment possibilities, making the welder ideal for most welding applications.

The welder has a highly robust structure. The base and column are painted steel. The motor that drives the central shaft is the brushless type. Movement of the transducer holder head is pneumatic, controlled by a proportional valve, and takes place on high-precision prismatic guides with excellent mechanical features.

One of the most important features of this welder is the cycle control system managed entirely by a MICROPROCESSOR.
It is possible to weld using the time function, and with the height function. In this case, the welding height is managed by optical ruler with centesimal resolution. Different thrust pressures can be set for each cycle phase, head descent, welding and compression.
The microprocessor can store 20 welding programs.
