The Only Bulk Manufacture of Fuxing High-Speed Railway Rake Discs Introduces CHN Leading Sand 3D Printing Intelligent Production Line

Introduction: Nowadays, more and more foundries are using 3D printing technology to manufacture sand moulds, and even introducing sand 3D printing equipment into their factories for the production of casting sand moulds and cores, replacing the traditional method of sand mould manufacturing.

On 25 September 2023, NJB was informed that Wenshanghaiwei Locomotive Parts Co., Ltd. introduced a set of sand 3D printing equipment this year. Wenshanghaiwei is a key parts manufacturer of China's high-speed railway Fuxing, and is currently the only batch manufacturer of brake discs for China's high-speed railway Fuxing, as well as a wholly-owned subsidiary of Boshen, a holding company of the Institute of Iron Science, which is a leader in the manufacture of Chinese high-speed railway brake discs.

According to NJBX, the WEN Shanghai Wei introduced sand 3D printer by Guangdong CHN Leading Intelligent Technology Co., Ltd. research and development and manufacturing, the use of 3DP technology, model L121006 high-speed version of the molding size of 1250mm × 1000mm × 600mm, the printing efficiency of 104-173L / H, printing efficiency year-on-year increase of more than 50%, it can be easy to achieve the complex structure of the , small and medium batch casting sand production. At present, the 3D printing equipment has completed the acceptance and put into the WEN Shanghai Wei Technology R & D Centre to use.

Before this, the R&D of casting process in Wenshanghaiwei was carried out by the method of traditional molds for R&D and testing samples, which not only had a long R&D time and high cost of molds, but also made the modelling operation of complex parts very difficult and the verification of process testing very passive. The introduction of CHN Leading sand 3D printer has effectively solved the problem of surface quality of cast steel parts; moreover, in the research and development of new products, the production of single or small batch products, process technology testing, the application of complex high-end casting products, it can effectively shorten the research and development cycle, greatly reduce the investment in various costs, and the results of the process experiments can be quickly responded to, with a very high value of the application of its advantages are very obvious.

Wenshanghaiwei introduced this sand 3D printing equipment printing speed is very fast, single layer printing time of 12 seconds / layer, a veritable industrial-grade high-speed printer, in the printing test brake disc sand core, Wenshanghaiwei company printed 5 brake disc casting sand core, the printing time of only 2 hours, well received by the user.

After printing, the loose sand around the prints is being cleaned up

The sand 3D printer developed and manufactured by CHN Leading adopts self-developed special binder for 3D printing, the advantages of which are less corrosive to the nozzle, longer service life of the nozzle, less odor and more environmentally friendly when printing and casting, and more suitable for casting steel or stainless steel parts; the sand material is open source, with silica sand, ceramic sand, etc., as the raw sand, and the user selects the corresponding raw sand according to the characteristics of the product; The sand 3D printer developed and manufactured by CHN Leading adopts linear motors, with higher printing precision and ±0.3mm full-size precision of the sand; the patented design of anti-fracture 3D printing ensures better printing quality. The sand 3D printer introduced by Wenshanghaiwei is a strategic project of the technology R&D Centre, which is located in the R&D and testing of new technology and new process, as well as small batch production.

In addition to developing and manufacturing brake discs for high-speed railways, Wenshanghaiwei Wei's products also include cylinder head assemblies for internal combustion locomotives and engineering machinery parts, all of which are produced by casting process. The introduction of sand 3D printer is also used to complete the internal combustion locomotive cylinder head assembly, engineering machinery parts of the R & D and small batch production.

Printed sand moulds for construction machinery parts and cast steel blanks for casting

It is reported that Wenshanghai is committed to building a high-end technology research and development center, and has invested 50 million this year to expand its technology research and development center. The introduction of Neutral Tripod's sand 3D printers, in addition to continuing to make efforts in the research and development of high-speed rail fittings technology to consolidate its position as a market leader, but also to expand the company's technological research and development capabilities in construction machinery fittings, to further expand the product line.
