Therefore, before participating in the exhibition, ordinary enterprises will make prototypes in advance for the rainy day. Those enterprises need to be prepared when...

2019-06- 11 11: 53 Generally, the product research and development industry is made by a prototype factory or a prototype factory, the role of the prototype model is to do experiments, test how the sales volume is in the market, or win the big customers at the exhibition. The experiment mainly depends on whether the internal structure is reasonable, but the latter two functions are especially important...

2017-09- 05 16: 14 What is the transcript? many people are asking what is the number of copies, what is the role of the number of copies, and where to use it? The following is introduced by the extension model with more than ten years of experience in making prototypes: copying is usually called copying design, reverse engineering or reverse design. As the name implies, copying is to copy...

2019-05- 10 09: 11 after the drawing of a new medical equipment product is completed, the enterprise will process the medical prototype model for verification, making a prototype to detect the design defects of the product is a very critical link. If a good medical prototype factory is not found to make a prototype verification product and directly open the mold production, if there are some problems...

2017-03- 20: 57 since the prototype industry is an industry with a relatively low threshold, many prototype factories are mainly small workshops and few professional prototype factories are available. However, since most prototypes are used for participation, such prototypes are more strict in appearance processing. Once the prototypes are not well done, they will affect the effect of participation...

2019-01- 24 08:03 In the first two months, wang Gong, an engineer doing electronic products in Zhejiang, consulted the extension model when looking for the Zhejiang prototype factory on the internet. There is a newly developed product that needs to be a prototype to see the effect, in order to test whether there are any deficiencies in the design of the product, it needs to be improved. after...

The Assyrians fell like wild wolves, and his companions sparkled in purple and gold; The luster of their spears is like the stars of the sea, when the blue waves roll at night in the deep Galilee.
