28Khz Customized Assemble Ultrasonic PP Welding horn design automotion spot welding

Introduction:

Examples of PP plastic ultrasonic welding horn application: PP filter bag welding , PP plastic box welding , PP folder ultrasonic welding ;

PP plastic generally refers to polypropylene, which is a thermoplastic resin made by the polymerization of propylene. It is divided into isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene according to the arrangement of methyl groups.

Parameter:

Ultrasonic welding: Welding horn vibrating with ultrasonic frequency, friction and heat generation under predetermined time and pressure, so that the plastic joints are fused with each other, which is firm, convenient and fast.

PP is semi-crystalline and different from ABS. According to the analysis of the two materials, the welding effect of the two materials is also different. The higher the density of the plastic material (hard), the higher the welding strength of the lower density (higher toughness).

PP plastic-material performance: small density, strength stiffness, hardness and heat resistance are better than low pressure polyethylene, can be used at about 100 degrees. Has good electrical properties and high frequency insulation is not affected by humidity, but becomes brittle at low temperatures , Not resistant to mold and easy to age. Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts.

1.Crystal, low hygroscopicity, prone to melt rupture, easy to decompose after long-term contact with hot metal.

2.Good fluidity, but the shrinkage range and shrinkage value are large, and it is easy to cause shrinkage. Dent, deformation.

3.Fast cooling speed, the pouring system and cooling system should slowly dissipate heat, and pay attention to control the molding temperature. The direction of the material temperature is low and the direction is obvious. It is especially obvious at low temperature and high pressure. When the mold temperature is lower than 50 degrees, the plastic parts are not smooth and easy to produce Poor welding, leaving marks, warp deformation easily occurs above 90 degrees

Information required for quoting and designing an ultrasonic welding horn
If you are in need of a quote for an ultrasonic welding horn for a new application, here are a few key pieces of information that will be required by an ultrasonic horn manufacturer in order to provide you with an accurate quotation for the ultrasonic tooling:

• What's the dimension of the horn you need? if you have no dimension , tell us the welding area.
• Material - what's the horn material you prefer? Titanium alloy, alumium alloy, or steel?
• Quantity - How many parts do you anticipate producing (monthly, annually, life time, etc)?
• Frequency - What is the operating frequency of the ultrasonic welder that the ultrasonic horn will be used on (15 kHz, 20 kHz, 35 kHz, 40 kHz, etc)?
• Welder Information - What is the make and model of the welder that the ultrasonic horn will be used with (Herrmann, Branson, Dukane, etc)?
• Stud Size - What stud size is required to connect the ultrasonic horn to your booster (3/8-24, 1/2-20, M8x1.25, M10x1.5, M12x1.25, etc)?
• Depending upon the complexity of the application, more information may be required by the ultrasonic horn manufacturer but supplying the above information is a great place to start.
