Aluminum, zinc alloy die casting

Aluminum, zinc alloy die casting technology introduction

Aluminum alloy and zinc alloy die casting, as one of the modern metal products manufacturing industry important process, widely used in the production of precision parts. Since its establishment in 2010, with more than 30 years of industry experience and technological precipitation, Dongguan Zhenjun Metal Products Co., Ltd. in-depth layout of the field of metal die-casting for domestic and foreign customers to provide high-quality, high-precision metal structural parts, especially in the aluminum, zinc alloy die-casting has accumulated a wealth of practical experience and professional solutions.

What is Die Casting? --Overview of process principles

Die casting is a process method that uses high pressure to press molten metal into a precision metal mold (i.e. die casting die). The process has the characteristics of fast molding speed, high dimensional accuracy, good surface finish and mass production. Aluminum alloy and zinc alloy because of its good fluidity, mechanical properties and corrosion resistance, become the mainstream material of die-casting industry.
The die casting process is roughly divided into four stages: mold closure, liquid metal injection, holding pressure cooling, open the mold to take parts. The whole process is usually completed in a few seconds, greatly improving production efficiency and effectively reduce labor costs.

Aluminum alloy die-casting - lightweight and high-strength structural material selection

Aluminum alloy has the advantages of low density, good thermal conductivity, strong corrosion resistance, recyclability, etc. It is the material of choice in aerospace, automotive lightweighting, 3C electronics and other fields.

Aluminum alloy die castings have high strength and good structural integrity, and are suitable for structural parts subject to certain loads. Typical products include: automotive engine housings, transmission housings, laptop brackets, photographic tripod connectors, and so on. Through appropriate post-processing (e.g., sandblasting, electroplating, CNC finishing, etc.), aluminum alloy die castings are not only structurally stable, but can also achieve excellent appearance and texture.
Zhenjun adopts advanced vacuum die-casting and semi-solid forming technology in the field of aluminum alloy die-casting, which effectively controls defects such as porosity and shrinkage, and ensures that the products meet international standards in terms of strength, precision and stability, and satisfy customers’ dual requirements for functionality and aesthetics.

zinc alloy die casting - precision and meticulous ideal process

materials

Compared with aluminum alloy, zinc alloy has a lower melting point (about 400 ℃), higher fluidity and filler, so it is very suitable for the production of complex structure, thin-walled precision products. Zinc alloy die casting high dimensional accuracy, almost no follow-up processing can be directly assembled and used.

Zinc alloy die casting is commonly used in the manufacture of: digital camera parts, cell phone bracket, home appliance knob, medical instrument shell, small motor parts, jewelry accessories and so on. Especially in the manufacture of appearance parts, zinc alloy shows excellent polishability and plating adhesion ability, can easily realize bright chrome, nickel, paint and other surface effects, enhance product grade.

In Zenith’s die-casting workshop, zinc alloy die-casting adopts high-precision automatic die-casting machine combined with temperature control system to ensure that each finished product has consistent dimensional stability and excellent detail performance, which is widely recognized by customers of home appliances, 3C accessories and consumer electronics.

the importance of die-casting mold design

Die casting mold is the core of the whole die casting process. Reasonable mold structure design can not only improve the production efficiency and extend the life of the mold, but also reduce the scrap rate and ensure the quality of die castings. Zhenjun has an experienced mold design team, combined with modern CAD/CAE system and moldflow analysis technology (Moldflow), pre-analysis of the product structure, optimize the design of the runner, to avoid dead ends, shrinkage holes and other problems.

The selection of mold steel, mold temperature control, parting line design, exhaust system arrangement, etc. are all carefully considered to ensure that the mold can produce high-quality die castings in a long-term and stable manner.

post-processing and surface treatment - a key link to enhance product competitiveness

Finished die-cast products often also need to go through deburring, drilling and tapping, sandblasting, anodizing, plating, painting, CNC finishing and other post-processing processes to meet the customer’s individual needs in terms of structural assembly and aesthetics. Especially in the field of high-end consumer electronics and precision medical devices, the appearance and feel of the products put forward a very high standard.

Zenith is equipped with a complete post-processing line, which can quickly customize process solutions to meet different customer needs, ensuring delivery and giving higher added value to the products at the same time.

Environmental protection and sustainability in aluminum and zinc die casting

In today’s carbon-neutral context, the recyclable nature of aluminum and zinc alloys makes them increasingly important in the environmental protection industry. Waste materials in the die casting process can be melted and utilized repeatedly, significantly reducing the waste of raw materials. Zenith always adheres to the concept of green manufacturing and introduces energy-saving furnaces and exhaust gas recovery systems to reduce carbon emissions and realize clean production and sustainable development.

Customization and Global Supply Chain Collaboration

With the rise of the trend of “personalized customization”, customers have put forward higher requirements on the structure, function and appearance of die castings. Zhenjun in the early stage of product design that is in-depth communication with customers, from material recommendation, structure optimization, sampling verification to mass production delivery, all provide one-stop service, to ensure that each customized parts are adapted to the actual application needs.
In addition, the company has established an efficient and stable supply chain system, the products are exported to Southeast Asia, Europe and the United States, the Middle East and other regions, and has gained wide recognition in the international market.

Aluminum, zinc alloy die casting is not only one of the important basic technology of manufacturing industry, but also an important support to promote high-end equipment, consumer electronics, intelligent manufacturing continuous innovation. Dongguan City, the real Jun Metal Products Co., Ltd. with many years of deep experience and innovative spirit, and continue to provide various industries with high quality, high efficiency, environmental protection of the metal die-casting solutions, to help customers in the global market to win the first opportunity.
