What Chenggong makes
Chenggong sorts its catalogue into four groups: ultrasonic core components, liquid-treatment equipment, complete equipment and welding products. The company introduction names transducers and ultrasonic drive supplies, often called generators, as its key products. A buyer can come to Chenggong for a single part, for a full machine, or for both on one order.
The application pages split the joining work four ways: plastic, metal, nonwoven fabric and geogrid. Each one calls for different tooling and a different joint check. Treat the list as a map of the work Chenggong targets and open the conversation with the application that matches your part. For horns, boosters and joint design basics, see our guide to ultrasonic plastic welding.

Company background
Chenggong gives its location as Fuyang in Hangzhou, Zhejiang. The full company name is Hangzhou Chenggong Ultrasonic Equipment Co., Ltd., and that is the name to put on purchase documents. The website also makes statements about market share, patents and certifications.
A 2022 contract-credit enterprise list published by the Hangzhou market regulator names the company for a stated two-year period. It is a useful record of the company name over that time. Current status and machine documents are separate questions, listed under Confirm before ordering.
Replacing a transducer or generator
Replacing a transducer or generator in a machine you already run is a matching job. Send Chenggong the identities of the existing components, how they connect mechanically and electrically, and any manuals or drawings you hold. Say whether you are swapping a part inside a working machine or developing a new process. The two lead to different offers.
Describe the whole stack: the horn, the booster where there is one, the mounting, and the way the machine controls the ultrasonic cycle. Photographs help Chenggong recognise the connections. Add dimensions and the electrical interface so the engineers can match them. A nominal frequency or power label is too little to pick a part on its own. Ask what changes the swap needs and who signs off the assembled system once the new part is fitted.
Plastic, metal, nonwoven and geogrid briefs
Each joining application needs its own brief, even though the same family of ultrasonic hardware sits behind all of them.
Plastic: name the polymer, any fillers and the joint geometry. Metal: state the actual metal pair, whether you join sheet or wire, and whether the joint must carry current, hold a load, or both. Nonwoven: describe the fabric build, the layering and the finished seam you need. Geogrid: show the joint pattern, the material and the finished geometry.
With that brief in hand, ask Chenggong to propose the full tool and workpiece arrangement and to explain how the joints will be accepted. Settings, frequency and throughput from one application rarely carry over to another, so ask for figures worked out on your own part.
Tooling, controls and integration
For a complete machine, ask for the tool-contact geometry and the fixture that will hold your part. Get a clear list of what ships with the machine and what you must design or buy yourself. Ask how the generator and components connect to your line controls, and how the system reacts to an incomplete or abnormal cycle. A general drive-supply description says little about cycle monitoring, so ask which signals the controls actually record.
If the ultrasonic unit goes into another machine, define the mounting space, the service access and the signals passed between the two systems. Agree who commissions the assembled equipment and who keeps the accepted setup in order. Our welding automation overview covers this split of duties for integrated cells. The quoted components, tooling and controls should appear by name in the trial record. That way you can tell a tested package apart from a parts order with engineering still to do.
Trial on representative parts
Agree the physical or functional checks for the finished product before the trial begins. Build the sample set from real parts with their normal incoming variation, and log failed joints alongside good ones. On a component project, test the complete assembled system under your real workload. A bench reading tells you little about production.
Watch loading, joining and unloading, including the pauses and part changes your line will have. Keep the tooling and settings together with the accepted samples. Your technical team picks the strength, leak, electrical or other tests that matter for the product. Our guide to sample trials and acceptance sets out a full trial plan.
Quotes, spares and support
Ask for drawings or part identifiers good enough to reorder matching components and tools later. Find out whether a repair changes the accepted setup and how the process is checked afterwards. Request the manuals, the utility requirements and the operator training Chenggong proposes.
Terms differ for a single component, a complete machine and a custom integrated station, so ask for each to be priced on its own line. When you compare quotations from several ultrasonic makers, line up the same package: source, horn, fixture, controls, commissioning and spares. A sound order rests on a clearly listed package, documented compatibility and a good result on representative parts.
Confirm before ordering
Ask Chenggong to confirm these points in writing before you place the order.
Compatibility: any replacement transducer, generator or horn works with your existing stack and controls, and the changes it needs are listed.
Package: the exact source, tooling, fixture, controls and utilities included, and who commissions the assembled system.
Certificates: current documents covering the exact model and scope, if certification matters in your market. This includes the market-share, patent and certification statements on the website. Our guide to verifying welding equipment certificates explains what to check.
Commercial terms: delivery time, warranty, spare-parts stock and local service.
Company status: the 2022 Hangzhou list helps with the name history, so ask for current company papers for the contract.
End-product rules: for medical products, battery connections or civil-engineering materials, your own team sets the acceptance tests and carries out the regulatory review.

| Transducers and ultrasonic drive supplies [1] | Named as Chenggong's key products in the company introduction. | Send the existing stack, connections and control interface; ask for a written compatibility answer. |
| Ultrasonic core components [1] | A catalogue group of its own. | Say which machine the part goes into and who assembles and accepts the system. |
| Complete equipment and welding products [1] | Listed as catalogue groups alongside the components. | Ask what the machine includes: source, horn, fixture, controls and commissioning. |
| Plastic joining [1] | Has its own application section on the website. | Give the polymer, fillers and joint geometry, and the tests the joint must pass. |
| Metal joining [1] | Has its own application section on the website. | State the metal pair, sheet or wire layout, and the electrical or mechanical job of the joint. |
| Nonwoven joining [1] | Presented as a distinct application. | Describe the fabric build and layering, and ask for a trial seam to your finished spec. |
| Geogrid joining [1] | Presented as a distinct application. | Show the joint pattern, material and finished geometry; ask for a trial on a representative joint. |
| Liquid-treatment equipment [1] | A separate catalogue group from the joining machines. | Request its own specification sheet if you buy it with welding equipment. |
Buyer questions
What does Chenggong Ultrasonic make?
Ultrasonic transducers and drive supplies are its key products. It also lists core components, complete equipment, welding products and liquid-treatment equipment, with joining applications for plastic, metal, nonwoven and geogrid. [1]
Is a transducer a complete welding machine?
No. A working station also needs the generator, horn and booster, tooling, a fixture, controls and integration into your line. Ask Chenggong which of these the quote covers.
Can I order a replacement by its nominal frequency?
Frequency alone is too little. Send the full existing arrangement and ask Chenggong to document the mechanical, electrical and application fit of the part it offers.
What does the 2022 Hangzhou contract-credit list tell me?
It names the company in a 2022 list covering a two-year period, which helps with the company name history. For current legal status, certificates and machine acceptance, ask for current documents. [2]
Who sets the acceptance tests for my parts?
Your technical team. Choose the strength, leak, electrical or other tests for the finished product and run them on representative parts during the trial.
