PROGRAMMABLE MOTION FOR PRECISION ULTRASONIC ASSEMBLY
Dizo Sonics servo ultrasonic welding machines combine programmable press motion with a tuned ultrasonic system for plastic assemblies that benefit from controlled approach speed, trigger position, weld collapse and final-position monitoring. 20 and 35 kHz reference configurations cover a range of precision and power requirements.
Servo actuation does not automatically create a good weld; it makes the mechanical motion more programmable and measurable. Material compatibility, molded-part variation, energy-director design, horn contact and fixture support remain decisive. The machine is configured only after the joint and acceptance plan are reviewed.
The reference values below come from Dizo Sonics legacy DZ-F configurations and are presented as selection guidance. Final frequency, power, servo capacity, sensing, controller functions and machine envelope are defined in the project quotation and validation plan.

|
Multi-variant production |

Ultrasonic welding converts electrical energy into high-frequency mechanical vibration and delivers it through a tuned acoustic stack. Under controlled force, localized heating develops at the designed joint or stake feature, followed by a short hold stage while the polymer solidifies. The process is fast and uses no adhesive, but repeatability depends on resin grade, molded-part consistency, joint design, horn contact, fixture support and a validated process window.

|
Material or design factor |
Application guidance |
|
ABS, PC/ABS, PC, PS |
Common ultrasonic candidates when joint geometry and cosmetics are suitable. |
|
PP, PE and other semi-crystalline resins |
Feasibility depends strongly on near/far-field distance, stiffness, joint design and fillers. |
|
PA and filled engineering resins |
Moisture, reinforcement level and horn wear must be reviewed during trials. |
|

Often challenging; test the exact grade, thickness and support condition. |
|
Dissimilar materials |
Do not approve from generic resin names; validate chemical compatibility and melt behavior. |
Always confirm weldability with the exact production resin grade, additives, fillers, color, moisture condition and molded-part geometry. Generic resin-family names are not approval evidence.

Question |
Answer |
|
What does the servo axis control? |
It controls the press motion profile and position. The exact trigger, force and collapse functions depend on the selected sensing and controller package. |
|
Does servo control eliminate the need for trials? |
No. Trials remain essential because ultrasonic weldability depends on the resin, molded parts, joint, horn and fixture. |
|
Which model is suitable for my part? |
35 kHz often suits smaller precision features while 20 kHz supports larger tools and higher power, but final selection requires an acoustic and application review. |
|
Can process data be exported? |
Yes, when the required fields, format, storage period and interface are included in the project scope. |
|
What information is required for an application review? |
Please send part 3D data and drawings, exact resin grades, joint or stake details, production-equivalent samples if available, CTQ and test requirements, takt, annual volume, variant mix, utilities and plant standards. |
|
Can Dizo Sonics test our real parts before quotation? |
Yes. An application review and representative-part trials are recommended when feasibility, tooling concept or cycle assumptions need evidence. Trial scope, sample quantity and test method are agreed before testing. |
|
How is the final cycle time confirmed? |
The committed cycle is based on trials and a complete sequence study including loading, clamping, joining, cooling, inspection, data handling and unloading. Published reference cycles are not universal guarantees. |
|
Which plastic materials can be processed? |
Suitability is approved at exact-grade level. Resin chemistry, fillers, moisture, additives, color, recycled content, molded-part variation and joint design can all change the process window. |
|
What documents are supplied with the machine? |
The project handover package can include the approved specification and layout, electrical and pneumatic documentation, manuals, maintenance plan, spare-parts list, parameter backup, inspection records and FAT documents according to the contract. |
|
Do you support FAT, installation and SAT? |
Yes. FAT and SAT activities are defined in the project plan. Installation, training and on-site support depend on destination, responsibility split and the commercial scope. |
