Development of die-casting parts for engine suspension brackets

In the field of automobile manufacturing, the engine suspension bracket is an important component connecting the engine and the body. It not only bears the weight of the engine, but also transmits the force and torque acting on the engine. With the development trend of lightweight automobiles, traditional ductile iron materials are gradually replaced by lighter aluminum alloys. Qinghe Zhelin Auto Parts Co., Ltd. (hereinafter referred to as "zlautoparts"), as a professional manufacturer of automobile chassis rubber parts and engine brackets, keeps up with industry trends and is committed to developing lighter, stronger and more durable engine suspension bracket die-casting parts.

1. Material selection and process innovation
zlautoparts used Al-10Si-Mn-Mg aluminum alloy materials when developing die-casting parts for engine suspension brackets. This material can produce high-quality castings under vacuum die-casting conditions of 91~96kPa through metamorphic treatment during the smelting process. The subsequent T5 heat treatment further improves the mechanical properties of the material and ensures fatigue life.

2. Application of Finite Element Analysis
During the design and development process, zlautoparts used finite element analysis (FEA) technology to optimize the design of die-casting molds. Through CAE technology, zlautoparts can accurately determine the pouring system and reasonably layout the pouring system and overflow system, thereby avoiding casting defects, shortening the development cycle, and reducing development costs.

3. Mold design and manufacturing
The die-casting mold designed by zlautoparts uses advanced mold materials and manufacturing processes to ensure the durability of the mold and the accuracy of the casting. The mold design includes multiple precision components such as the upper core-pulling cylinder, the travel switch fixing plate, and the upper core-pulling cylinder bracket to ensure the precise operation of the mold.

4. Quality control and testing
zlautoparts conducts strict quality control and testing on the engine suspension bracket. The castings are strictly inspected before and after cleaning to ensure that the diameter of a single pore defect inside is less than 2mm and the porosity of any section is less than 5%. In addition, zlautoparts also conducts fatigue strength tests on the castings to ensure that their fatigue strength under certain load conditions meets the technical requirements.

5. Industry experience and technical strength
zlautoparts has rich industry experience and strong technical strength. The company is not only able to develop and produce according to the samples provided by customers, but also can provide one-stop service from design to manufacturing. The product categories of zlautoparts cover 10 major series, including suspension bushings, engine foot rubber brackets, opening rubber, shock absorber top rubber, tie rod assembly, etc., serving multiple car brands.

6. Market positioning and customer service
zlautoparts has a clear market positioning and focuses on providing high-quality chassis rubber parts and engine brackets for automakers and repair shops. The company's sales network is spread all over the world, and its products are exported to many countries and regions. zlautoparts provides not only products, but also considerate services and solutions to meet the diverse needs of customers.

In summary, Qinghe Zhelin Auto Parts Co., Ltd. has demonstrated its technical strength and market competitiveness in the development of engine suspension bracket die castings. By adopting advanced materials, processes and quality control, zlautoparts has successfully provided the automotive industry with lighter, stronger and more durable engine suspension bracket solutions.
