Why Choose Tongrun International?

Putting ourselves in the shoes of our customers, we've come to learn that their expectations for a manufacturer in China are fairly simple. They want a company they can trust. They want a company with experience. Most importantly, they expect that their products will be manufactured to meet their cost, quality and time targets. Through our years of experience, we've learned how to take on our customer's requirements and to exceed their expectations through proactive communication and on-time delivery.

Do you offer production of prototypes or just high volume production runs?

Whether it is a low volume prototype or high volume production run, you can have Tongrun International assemble and test your product to meet your exacting requirements and demanding delivery schedules. Components used can be supplied from your consigned inventory or purchased directly by Tongrun International as a full turnkey service - or a mix of both. DFM (design for manufacturability) and DFT (design for testability) services are utilized to help you optimize the cost and increase yields to deliver defect-free products.

What type of Testing Services do you offer?

Tongrun International offers a full range of testing services - from developing the test programs to testing your product. In-house capabilities include first in, functional, pull, ingress and end-of-line. Selecting the optimal method for your project depends on your unit volume and other factors. Our trained engineering staff is available to help you make the best choice.

How will communication regarding my project be handled?

Cross-functional and cross-company communication is critical to the success of any project. Your project is assigned to a Project Manager who is the central point of contact for the team made up of your staff and ours. You are kept up-to-date about your project and related issues - no surprises. You can request customized reporting and program review formats that meet your specific requirements. Tongrun International is also very flexible in adapting to delivery schedule changes driven by fluctuations in your business.

What type of Industries does Tongrun International serve?

For the most part, Tongrun International is agnostic about which industries it serves. We see most products as a series of manufacturing processes. However, we have learned that experience in certain industries has allowed us to gain insight and knowledge into the specifics of certain products. Different industries require different sensitivities and can have specifications and certifications exclusive to them. We have experience with a diverse set of customers in severa different industries. These include military, computers & peripherals, medical, telecommunications, automotive, industrial and consumer. At Tongrun International, you will find the expertise and processes well suited to serve your specific industry requirements.

Is Tongrun International a financially stable company?

This is an important question. Once you've committed to a manufacturer, the last thing you need is to have them fail finanically, leaving your project high and dry. Tongrun International is a strong, financially stable company that is publicly listed on the Shanghai Stock Exchange. With year-after-year of continuous growth, prospects have never looked better.

Who are some of your current clients?

We have and are currently manufacturing for several leaders in their respective industries. Our clients' supply chain is often part of their intellectual property and, as such, we only reveal their identities on a case-by-case basis.

What does Tongrun International need in order to quote a job?

First and foremost, we need electronic files for the job we are to quote. We cannot quote unless we have them. These can be 3D or 2D files, as long as they contain information about the size and material weight of the project. We accept SolidWorks, Pro/E, AutoCAD and PDF files. We will also need material requirements and an estimated annual usage.

What jobs are suitable to do with Tongrun International?

We excel at manufacturing highly engineered products whether the volume is large or small. Some projects make sense to manufacture with Tongrun International and some don't. We will work with you to help make that determination together.

Does Tongrun International use certified materials?

We take pride in always using agreed upon, certified materials for production. We have global agreements with companies such as GE, DSM, Dupont, BASF and reputable local vendors which allow us to secure the right materials at a competitive rate. We can send material certifications for samples and production runs as required.

How do you protect my intellectual property?

We value our integrity and honor our confidentiality with our customers. We will not divulge any information that might compromise our customers' positions.

Do you have a minimum required volume?

We do not have a set minimum volume per sť. We evaluate each job on a case-by-case basis to determine if it is going to be cost effective for our company and your company. Many times, product volume will play a substantial role in making this determination.

What is your in-house engineering expertise?

Our large engineering staff has countless years of engineering experience. We utilize this experience to oversee design, manufacturing, validation and quality control. We can do 3D modeling, 2D drawings and simulation through Pro/E, AutoCAD, SolidWorks and UG.

What communication tools do you utilize?

Besides conventional communication tools such as phone, fax and e-mail, we also utilize FTP for large file transfers, online meeting services for presentations and conference call services for group meetings.

Will language be an issue?

All of our project managers and engineers will be able to communicate effectively in English through every step of your project.

How do I import the finished product?

Our logistics department will take care of all necessary governmental and commercial procedures on both sides. The whole process will be transparent to you. We'll be just like your vendor down the street.
