On April 26, SDWQ Light Alloy Material Technology Group invested in the construction of automotive lightweight parts R & D, production base project held a ceremony. The project is mainly dedicated to the development and production of lightweight application products in highway transportation, rail transportation, communications, military and other industries, and further promotes the transformation and upgrading of the local aluminum industry through the rapid development of high quality.
The new project realizes the supply of all-aluminum body through the development of three-dimensional bending technology, low-deformation high-strength welding technology, high-reliability cold chain technology, frame structure optimization simulation technology, etc., and fully develops the lightweight aluminum alloy material market for transportation. Mass-produced vehicles are manufactured using split and assembly. The pilot test base will be built into the world's leading aluminum lightweight material research and development center, striving to become the largest and most advanced lightweight comprehensive base in China. It has the largest domestic production scale, the most complete equipment models, and the most advanced technological capabilities. The cost advantage is the most obvious. The liquid (semi-solid) die forging (squeeze casting) high-end aluminum alloy structural parts lightweight product development and manufacturing base with world advanced competitiveness.
Base construction Lightweight pilot test base project, lightweight aluminum profile project, lightweight full-body assembly project and lightweight extruded structural parts project, with a total construction area of 102,300 square meters, purchase and installation of automated hydraulic stamping lines and automated connections Equipment (six-axis robot) and other major equipment 155 sets (sets), reaching an annual output of 250,000 stamping parts, 50,000 sets of body-in-white assembly, 50,000 sets of profile parts, 100 sets of extruded liquid molds, lightweight extrusion The scale of compacted structural parts is 3.75 million pieces.
The total investment of the project is 1.736 billion yuan. The project plans to invest 907 million yuan in 2020. As of April 24, 2020, it has accumulatively completed an investment of 146 million yuan, 16.1% of the annual plan.
The core technology of the lightweight extruded structural parts project, the liquid die forging (squeeze casting) process has many advantages such as high product performance, wide application of materials, and strong process expansion. It is an important means to achieve high-strength aluminum-based lightweight. This technology was included in the key development direction as a key technology for solving aluminum alloy chassis structural parts in the road map of automotive technology development announced in 2016. It was also included in the national "manufacturing basic technology and key components" focus in 2019 Special support is given to support 5G communication base station structural parts. At present, Huawei / ZTE has listed squeeze casting as the designated process for 5G base station structural parts.
Relying on the advantages of SDWQ Group's existing aluminum resources, the lightweight full-body assembly project utilizes SZAJ all-aluminum lightweight design technology, mature body and parts products, and aims to develop core technologies for the development of lightweight parts and complete vehicle preparation for automobiles. Automated connection devices (six-axis robots), CMT arc welding robots, SPR robots, FDS robots, glue coating robots, body assembly main welding conveyor lines, etc., strive to create the world's leading automotive lightweight design, parts production and R & D , Prototype manufacturing center.
