Place of Origin:
China
Brand Name:
Tieke
Breif introduction:
Welded frame is the core part of welded frame bogie.
Tieke was direct factory belong to Chinese railways. The main technicians and workers have over 10 years working experiences in manufacturing railway wagons, and bogies. Our welders are qualified with professional welding certification. Tieke has accumulated rich experiences in manufacturing high quality welding frame for welding bogies, wagon car body and other welding structural product.
To ensure superior quality welded bogie frame, we take mainly two measures: one is to make reasonable production process and another is to adopt reasonable process methods and measures to ensure the key processes affecting quality
Features of reasonable production process:
Separate the guide frame machining process: leave some machining work after heat treatment to eliminate the influence of frame welding deformation, assembly deformation and heat treatment deformation, which ensuring the accuracy of the frame, reducing the manufacturing process difficulty and improving the qualification rate of frame production. |
Adding inspection and adjust process after each group’s assembly and welding. This could solve the deformation of each component, improve the next step’s assembly accuracy, and reduce the welding difficulty. |
Ensure the product qualification ratio |
Welded frame production process:
Key processes quality control
Control of components assembly accuracy |
Control of welding deformation and accuracy of frame in the process of final assembly. |
Adopt anti-deformation technology to control the accuracy of the frame, according to the deformation law. |
Control of frame deformation during and after heat treatment. |
3. Heat treatment conditions:
Heat treatment requirements for stress relief: the frame is heated to 550-570 ℃ with the furnace and kept in for 3h.

FAQ:
Q1: Are you a trading company or a factory?
A: We are directly a factory and we manufacture and export railway wagon bogies directly.
Q2: Do you have design ability to provide customized railway bogies?
A: Yes, we have professional technical team and we are familiar with international railway standards like UIC, AAR, EN and we are able to provide railway equipment according to customer requirements.
Q3: Chinese railway gauge is 1435mm, but our country’s is 1000mm gauge, will this be a problem for you?
A: Of course not, we are able to design railway wagon bogies of different gauges like 1435mm, 1000mm, 1067mm, 1520mm or other required railway gauges.
Q4: Why should I choose you, compared with your competitors?
A: Tieke Railway was transformed from wagons factory belong to Chinese Railway in 2016 and the company have over 10 years’ experiences in manufacturing railway wagons and bogies; Now as Tieke Railway is a private company and adopt modern market management strategies, our services are flexible and more considerate and our cost is more controllable.
Q5: What should I provide to get a quotation from you?
A: You could send your inquiry with detail drawings, product photos, detail technical parameters or requirement description. A complete requirement input is very important for us to provide an accurate quotation to you.
