Linear Vibration Welding Process:

STEP 1

Manual load thermoplastic halves into vibration welding jigs and have them held steadily with no lose by fixtures;

 

 

STEP 2

Elevating table ascends to the top height and forces two thermoplastic halves together under pressure;

 

 

 

STEP 3

Vibration system starts, by the pulling energy from the electromagnets at two sides of the springs, the vibration springs oscillation forces upper jig reciprocating motion in definite frequency and amplitude, by which friction is cased at the contacting surface of two thermoplastic halves to generate heating energy, the heating energy melts the thermoplastic material at the welding line until it reach melting volume.

 

STEP 4

Once the thermoplastic melting volume (time or depth) reach the set value, system stops vibration, then the vibration springs returns to zero position and bring the upper fixture back to its original position, then the machine system keeps compressing two plastic together by fixtures under pressure until jointing area cools and becomes re-solidified.

 

STEP 5

When the melted material at vibration joining area becomes re-solidified, the upper fixture releases the plastic part, then the elevating table descends descends to the original height, and then releases the finally welded plastic parts. The vibration welding cycle is finished, then manual remove the finished parts from vibration welding machine.
