Toilet Seat Vibration Welding

Closestool is necessary for a family, and intelligent closestool seat cover now is more and more welcomed for its comfortable toilet experience. The assembly closestool cover requests thermoplastic joint to toilet seat because of its safety standard.

I. Why it requests welding to toilet seat?
The heating system inside toilet for warming requests waterproof of assembly of toilet seat.
II. Material: A. ABS; B. PP.
III. Weld Methods: A. Hot Plate Welding; B. Vibration Welding.
IV. Critical requirement: A. Airtightness; B. Beautiful outlook welding result; C. Protection to surface.
V. Challenge of Welding: 
A. Toilet seat parts is in big size, big deformation exists in molded parts before welding;
B. None uniformed shrinkage of injection moulding bringing high difficult to reach good welding result in outlook, which requests high precision control in welding;

C. Material especially PP is more challenging than ABS;

D. High requirement for exterior apperance requests protection of sruface and no burr control during welding.

VI.    Suggested Welding Methods: Vibration Welding.
VII.Advantages of Vibration Welding to Toilet Comparing Hot Plate Welding: 

A. Can rectify the deformation of parts before jointing by high pressure force before welding which is difficult to be realized by hot plate welding melting;

B. Stability in qualified welding result;

C. Realize programmable welding process control in high precision;

D. High production effeciency (short welding cycle time);

E. Keep heating system inside closestooling from damage by heating tooling.

IX.Suggested Welding Equipment:
A. Machine: Linear Vibration Welder MSV-650LS (Machine Specification);
B. Linear Vibration Welding Tooling.
