Ultrasonic Welding Sample Testing Service

Validate your parts before selecting ultrasonic welding equipment.

TIMEAST evaluates ultrasonic plastic welding feasibility using your actual parts, drawings and performance requirements. Testing helps determine whether ultrasonic welding is suitable, identify potential joint or tooling issues, and recommend an appropriate machine configuration before you invest in production equipment.

Request Sample Testing

If testing can be completed with existing tooling, the sample welding test and basic feasibility evaluation are free. 

If a dedicated horn or fixture is required, the tooling cost will be quoted for your approval before fabrication.

What We Evaluate

The evaluation scope is based on your part design and production requirements. It may include:

• Plastic material compatibility

• Joint design and welding-area suitability

• Weld strength, appearance and consistency

• Sealing or leakage risk, where applicable

• Suitable ultrasonic frequency and power range

• Servo or pneumatic machine selection

• Horn contact and fixture-support requirements

• Risks such as flash, marking, deformation or part damage

• Preliminary cycle time and automation feasibility

What You Need to Provide

Please send the following information before shipping physical samples:

• Photos of the assembled and unassembled parts

• 2D drawings or 3D files, if available

• Exact plastic material grade, including fillers or additives when known

• Required weld strength, sealing performance and appearance standard

• Test pressure, holding time or permitted leak rate, if sealing is required

• Target production volume and cycle time

• Photos or videos of any current welding defects

• Available sample quantity and whether samples need to be returned

Clear acceptance criteria help us evaluate the result correctly. If no specific standard is provided, 

the test can indicate basic welding feasibility but cannot confirm final production acceptance.

How Sample Testing Works

Step 1: Application Review

Send part photos, drawings, material information and performance requirements. We first review material 

compatibility, joint design and the likely welding method.

Step 2: Sample and Tooling Confirmation

We confirm the sample quantity, shipping details, return requirements and whether existing tooling can be used.

If testing requires a custom horn or fixture, tooling charges may apply. After your approval, 3–4 working days 

are normally required to prepare the tooling, depending on complexity.

Step 3: Welding Trials

We select a suitable ultrasonic welding system and adjust the relevant parameters. Multiple samples may be tested 

when strength, sealing, appearance or repeatability needs to be compared.

Step 4: Results and Recommendation

We summarize the test findings, preliminary parameter range, tooling requirements,observed risks and recommended

equipment configuration. Photos or videos can be provided as part of the agreed evaluation.

What You Receive

After sample testing, we provide practical information to help you evaluate the welding process and select 

suitable equipment. Depending on the agreed test scope, you may receive:

• Welding feasibility assessment

• Recommended ultrasonic frequency and power range

• Recommended servo or pneumatic welding system

• Preliminary welding parameters

• Horn and fixture recommendations

• Photos or videos of the welding trials

• Identified risks and recommended next steps

Example of an ultrasonic welding sample test result. Actual evaluation results depend on part design, material and performance requirements.

The test result will indicate whether the application is suitable for ultrasonic welding, requires further design or tooling optimization, or is not recommended for ultrasonic welding.

Sample testing is a preliminary feasibility evaluation. Final production validation may require additional trials under 

actual manufacturing conditions.

Pricing and Sample Shipping

Welding Test Evaluation

If testing can be completed with existing tooling, the sample welding test and basic feasibility evaluation are free.

Custom Horn and Fixture Costs

Some products require a dedicated ultrasonic horn or fixture for accurate testing. Any tooling cost will be evaluated

and quoted for your approval before fabrication.

Shipping and Sample Handling

Please contact TIMEAST before sending samples. We will confirm the delivery address, required quantity, 

test scope and return requirements.

Some samples may be welded, pulled, pressure-tested or otherwise damaged or consumed during evaluation. 

If samples must be returned, please tell us before shipment so the arrangements can be confirmed in advance.

Customer drawings, samples and project information are used for technical evaluation and will not be published 

without customer approval. If a formal confidentiality agreement is required, please confirm it before sending 

files or samples.

Why Test With TIMEAST?

• Testing based on actual customer parts and requirements

• Access to servo and pneumatic ultrasonic welding systems

• In-house support for custom ultrasonic horns and fixtures

• Equipment and automation recommendations based on test findings

Frequently Asked Questions

Is ultrasonic welding sample testing free?

The welding test and basic feasibility evaluation are free when existing tooling can be used. 

If a dedicated horn or fixture is required, the tooling cost will be evaluated and quoted for 

your approval before fabrication.

How many samples should I send?

The quantity depends on the part structure and required evaluation. Send photos and drawings first, 

and we will confirm the sample quantity before shipment.

How long does testing take?

The schedule is confirmed after reviewing the application, samples and tooling requirements. 

If custom tooling is required, preparation normally takes 3–4 working days after approval, 

depending on complexity.

Does a successful test guarantee mass-production results?

No. Sample testing provides a preliminary feasibility assessment and equipment recommendation. 

Final production approval may require repeated trials and validation under actual manufacturing conditions.

Request Sample Testing

Send us your part photos, material information, drawings and performance requirements. We will review

 the application and confirm the required samples, testing scope and any tooling cost before you ship the parts.
