It is understood that the 3D printing unit of the 34 workshop of Xi’an Aerospace Engine Co., Ltd. (hereinafter referred to as “Xifa Company”) has undergone technological upgrading, which has greatly improved production efficiency, liberated productivity, improved product quality consistency, and achieved green casting.
The sand mold 3D printing unit is mainly responsible for the production of aluminum alloy casting sand molds for various types of engines. Compared with traditional manual modeling, sand mold 3D printing technology adopts digital moldless casting technology modeling, which realizes the upgrading of traditional foundry industry. The printing process is automated and unattended. Shorten the development cycle and reduce the R&D cost. Castings of any shape can be made, not limited by molds.
Driven by the mechanical CAD model, the sand mold 3D printing technology uses the three-dimensional inkjet printing technology to directly obtain the casting mold, which can realize integrated modeling, shorten the manufacturing cycle and reduce the manufacturing cost; convert the three-dimensional product into two-dimensional production, and can make any Shaped castings; while improving the dimensional accuracy of castings, reducing the weight of castings and ensuring dimensional consistency of castings.
After applying the industrial-grade foundry sand mold 3D printing system in the 34 workshop, the manual molding process is automated; the mold is processed by a completely closed digital moldless casting forming equipment, and a special dust removal auxiliary device is used to effectively prevent dust, waste gas and noise, and help green Casting.
