     PRODUCTIVITY: 500 balls/minute (1000 half balls/minute)- is the
         Biggest problem
     Diameter: 25 mm
     INJECTION TECHNOLOGY: Compression molding machine
         (1.000 pcs/hour)
     MATERIAL: Polipropilene High Density
     2. WELDING TECHNOLOGY
        -ultrasonic
•      - by friction
•      - direct contact
•     -indirect contact (laser or infrared)

 EVACUATION
   Imbinarea cu ultrasunete a bilelor deo-roll
Materialul de bază al asamblării îl
constituie reperele de material
plastic polipropilenă (PP). sub
forma reperelor disticte A si B

Tehnologia de sudare cu
ultrasunete impune o configuratie
specifica in zona de sudare                               A                    B


Conditii de acceptare tehnologie       Figura 4. : Repere semisfere ce urmează a fi
de sudare:                                         sudate cu ultrasunete
                                            Repere specializate distincte A, B
-sudura etansa;
-refulare material in interior si in
exterior produs sudat cu
repetabilitate;

Îmbinarea cu radiatii infrarosii a materialelor plastice,
   consta
in incalzirea pieselor de sudat cu ajutorul radiatiilor infrarosii
emise de lampa cu halogen, focalizata cu ajutorul unui
   sistem de
lentile sau oglinzi / reflectoare in zona de imbinat
    Sudarea cu radiatii in infrarosu se poate aplica la sudarea
   prin suprapunere sau cap lacap
                                                                            1
