Pressure die casting is the most widely used and the most efficient precision parts manufacturing technology. It adapts to the trends of product, like complexity, precision, light weight, energy saving and green environmental protection, in modern manufacturing. And such kind of technology is widely used in automobiles, home appliances, aviation, machinery, etc. There are 3 main die casting materials: aluminum alloy, zinc alloy and magnesium alloy.
From a global perspective, the die casting industry is a fully competitive industry. The quantity of die-casting companies in west countries is relatively small but the size of one single enterprise is large. It has strong advantage in terms of capital, technology and customer resources. Such as RYOBI Co., Ltd. in Japan, DGS company in Swiss, Kasma in Canada, Magna in Canada, George Fischer in Switzerland and so on. They have leading advantage of high-technology and high-quality for high requirement market, like automobiles and aviation. It is much ahead of most Chinese die-casting manufacturers in terms of technology and production scale.
However, China also have advantageous position in terms of market demand, raw material supply, labor resources, industrial chain support and cost. The global die casting production trend is shifting to Asia, especially mainland China and this trend continues. In recent years, China's die casting industry has maintained a steady growth of more than 10% each year.
In the past 20 years, the expansion of the market scale and the entry of outstanding international companies have promoted the improvement of the technical level and management level of domestic die casting manufacturers and further promoted the development of China die casting industry. China has formed the Yangtze River Delta, Pearl River Delta, Southwest Region and other die-casting industrial clusters. Among these industrial clusters, the Yangtze River Delta industrial cluster is the most prominent and it has formed various types of die-casting materials, various die-casting factories in various market segments, covering from batch automotive applications to low volume high mix demand, from simple requirements to precision die-casting requirements and have supporting industry chain nearby (e.g.surface treatment, heat treatment …).

Design, Prototyping, NPI and Validation
Using a variety of methods, most die casting suppliers act in partnership with our customers to optimize the products for manufacture. Effective collaborative design and innovative prototyping enables customers to successfully launch new products into the market.
Product engineering- Suppliers can develop die-casting tooling independently and all die-casting tools used are designed and customized according to the requirements of the customers. All the R&D personnel have professional background and have accumulated rich experience and summarized a set of advanced and efficient design concept through the long term cooperation with global well-known large multinational auto parts suppliers. In addition, the R&D personnel actively carry out simulation analysis on the flow of liquid aluminum and such impact factors by utilizing advanced technologies like computer aided design (CAD). Accordingly, mould and tooling design is optimized and improved and high-quality tooling can be trial-produced and manufactured.
Software for design and prototyping consists: Mold Flow; Solidworks; Simulation Analysis; CAD;
Mold Worksho
In house mold team adheres to scientific, rigorous and logical innovation concept through learning, digesting and absorbing advanced design theories and practices both at home and from abroad; keeps abreast of the industry's advanced technology; forms its unique advantage in the research and development of magnesium, aluminum and zinc (Zamak 3&5) alloy die casting tooling. With the core competitiveness of innovative independent intellectual property rights, the trial production and production of high quality tooling are realized and the mold team shares technology and experience with their customers.
- Mold team uses internationally mainstream 2D and 3D copyrighted software.
- Flow channel analysis uses German MAGMA casting simulation analysis software, including solution flow analysis, solidification analysis, mold temperature analysis, thermal stress analysis and die life analysis.
- Die-casting products have been consistently recognized by domestic and foreign partners. Mold manufacturing uses advanced imported equipment, such as five-axis machining centers, horizontal machining centers, large-scale high-speed machining centers, slow-moving wire cutters and electric sparks so as to make mold reliable and accurate.
Melting workshop
Over the years of accumulation and development, most die casting companies have core technology, including energy saving melting, automatic melting line, concentrate melting - heat preservation system and capability to produce different standard materials.
