Guobiao Ultrasonic

Guobiao's website puts ultrasonic drivers and automatic-control technology at the centre of the business. On the welding side it names three applications: nonwoven fabric, paper cups and automotive parts. The same site sells liquid treatment, extraction, dispersion and measurement products, which use ultrasound for very different jobs. So read Guobiao as a drive and control specialist that builds welding solutions around a task, and ask for a configuration matched to your part.

The exact company name, Hangzhou Guobiao Ultrasonic Equipment Co., Ltd., appears on a Zhejiang government list of high-tech enterprise filings from 2021. That entry helps you match the seller's name on a quotation. The site also mentions a development team, quality work and links with universities. For the purchase itself, judge the machine you are offered on its own documents and on a trial with your parts.

Each of Guobiao's welding applications needs a different brief. For a nonwoven seam, send the fabric construction, number of layers, web width and the seam pattern you want. For paper cups, send the coated board you actually use and a drawing of the side seam or bottom joint. For an automotive part, give the polymer grade, any metal inserts and the locating features on the moulding.

Then say what the joint has to do in service and which marks or deformation are acceptable on the finished part. Describe how much your incoming material varies and how parts will be loaded. Ask Guobiao to explain the welding method and the way the horn contacts the part for your exact job. A homepage application name gives you a starting point. A generator power quoted for a liquid treatment product belongs to that product, so request figures for the welding set you will buy.

If you want a Guobiao drive supply to fit an existing machine, send the identity of the transducer and horn you already run, the connectors and your control documents. Ask for a written answer on compatibility that lists any changes needed. Frequency and power on a label describe only part of the match, so the full arrangement should be reviewed against your application.

List the signals that must pass between the generator and your machine, who wires them, and what should happen if a cycle is cut short. If you need data logging or automatic rejection of bad parts, ask for a description of those functions on the quoted model and a sample record. Guobiao's control background makes these useful questions to raise early. Agree who commissions the assembled system and signs it off.

The joint is only one step in the cell. For roll goods such as nonwoven or cup stock, describe feeding, alignment, tension and support, and what happens to the material next. For discrete moulded parts, define how they are located, clamped and released. Ask Guobiao which of these stages the quote covers and which stay with you, because a good hand-made weld says little about an automatic line.

During a trial, watch start-up, stops and a material change, and count rejected parts and handling losses as well as good output. Judge the results with the same material and the same inspection method each time. If your product needs a leak test, a seam strength test or another functional check, set it with your product team before the trial and run it on the samples.

Ask for a trial report that names the generator, transducer, horn, fixture or feed system and the settings used. Add the condition of the incoming material and describe the full operation you watched. Keep the good samples and notes on the rejected ones. That record lets you check the delivered machine against the trial, and later judge a replacement horn or component against the same baseline.

Find out which settings operators may change and how approved settings are stored and locked. If one machine will weld several variants, include a real changeover in the trial and inspect the first good part after it. Your own engineers set the physical and functional requirements for the finished product, and they should confirm the offered configuration meets them.

Guobiao's liquid processing, extraction, dispersion and measurement products are separate lines. If you also need one of them, write a separate enquiry. A treatment probe has its own ratings, and a sound-intensity meter measures the field, so neither tells you whether a weld is good. Keep the welding enquiry focused on the joining task, the tooling and the acceptance test for your part.

Before you place an order, get Guobiao to state, in writing and for the exact configuration, the model and part numbers of generator, transducer and horn; utility needs; manuals; and the identifiers you will need to buy matching spare horns and components later. Ask who repairs the system, what training is included and how a replaced part is rechecked.

Price, delivery time, stock, certificates and local service should all appear on the quotation itself. The 2021 filing list helps you identify the company. The machine you buy is judged on current documents for that model and on a trial with your parts.
