3D printing sand mold technology of Zhengheng Power provides new solutions for green casting

In the wave of innovation and breakthrough in the manufacturing industry, the 3D printing equipment of Zhengheng Power is officially put on line and put into production!
3D printing sand technology in general terms is to design a three-dimensional model with the help of professional 3D modeling software, based on the use of castings, performance and other requirements. After the model is converted to STL and other applicable formats for 3D printing, it is directly inputted into the printer to realize intelligent production.

Advantages of 3D printing sand mold technology
Flexible design and manufacturing: In the past, traditional sand casting often faced many challenges when faced with the demand for casting of complex shapes, 3D printing sand can easily handle this type of complex sand by virtue of the digital model, and in the face of small quantities, customized casting orders, it does not require molds, according to the customer’s specifications, modeling and performance of the special requirements of the market to respond quickly to the diversified needs of the market.

Efficient cost reduction and efficiency: relative to the traditional sand casting time is long, 3D printing sand directly according to the digital model printing, modify the design in the computer operation after reprinting on the line, greatly shortening the product development and production cycle. Meanwhile, in terms of precision, dimensional accuracy can be controlled within ± 0.3mm, compared with the traditional process, do not need to invest in mold costs, saving time to make molds for 2 months (L4 cylinder block as an example). Secondly, due to on-demand printing, the material utilization rate of more than 90%, high degree of printing automation, manpower costs reduced by more than 60%, effectively cut production costs and improve economic efficiency.

Significant green environmental protection: traditional casting mold manufacturing produces a large amount of waste, high disposal costs and environmental pollution. In the production of 3D printed sand molds, the useless sand can be recycled, with very little waste, and the printing does not require a large number of chemical binders, reducing the emission of harmful gases.

The application of 3D printed sand mold is suitable for light weight, high performance and customization in various industries, and at the same time, it can realize rapid trial production and optimization, avoiding the difficulty of traditional technology to take into account the complex internal cooling structure and external aerodynamic shape.
The on-line of 3D printing technology of Zhengheng Power not only injects new vitality for its own development, but also hopes to provide more customers with better quality products, play an important role in more fields and create greater value.
