Project Name: New Austria Group Production Line

Mechanical model, as its name implies, is about the reduction of the proportion of machinery in real equipment, such as 1:10, 1:20 and so on. If the proportion permits, the production line model can simulate the working principle and demonstration of the real equipment. The mechanical model has the advantages of equal scale scaling, height simulation, suitable transportation and suitable exhibition. It is more and more favored by large machinery manufacturing companies. Through its unique development and special design, it continuously gives the model higher external expressive force and visual impulse. Strike force. It has special equipment and equipment for making ship models. This is an important means to solve the difficulty of production and to ensure the level of work technology. From a certain point of view, exquisite and delicate works are the expression of the ability of craftsmanship and tools.
