Our Advantages of Die Casting Machining

When it comes to machining, different metals require different processes.

Zinc Die Casting Machining

There is usually very little machining required on our precision zinc die castings because of the accuracy we obtain. The machining characteristics of zinc and zinc alloys are excellent and a wide range of machining processes can generally be used.

· Drilling—we can achieve better, more economical drilling under a wide range of operating conditions.

· Tapping—zinc die casting alloys are readily tapped and form excellent thread and hole quality. Threads can be cut or formed with and without lubricants and can be easily tapped using fluteless taps to produce a rolled thread. Fluteless tapping is carried out at higher speeds than cutting taps, and lubrication is essential

· Reaming—our precision zinc die casting process is so precise that holes are cored to the required size for reaming. This means we avoid drilling operations requiring the manufacturing of expensive jigs

Magnesium Die Casting Machining

Magnesium die casting alloys’ close-packed hexagonal structure makes them well-suited for the machining process.

· Good results are obtained when magnesium alloys are machined with tools designed for machining aluminum. But because of the low resistance to cutting and the relatively low heat capacity of magnesium, we use tools with smooth faces, sharp cutting edges, large relief angles, small rake angles, few blades (milling tools), and a geometry that ensures good chip flow during machining

· Traditionally, magnesium alloys were machined without using cutting fluids. However, we have found using cutting fluids reduces fire risk, eliminates material build-up on the tool, removes chips easily, and, most importantly, prolongs the life of the tool

Aluminum Die Casting Machining

The most widely used die casting alloy, Aluminum Alloy 380, is very good for machining purposes.

· High-speed steel tools are generally used for machining aluminum

· Spiral-flute reamers are preferable to straight-flute reamers when working with aluminum

· It is not necessary to use high clamping forces when machining aluminum. By using moderate clamping forces we avoid the dimensional variations that occur as a result of distortion

Types of Alloys Used in Pressure Die-Castings

Die casting is a manufacturing process for producing accurately dimensioned, sharply defined, smooth or textured-surface metal parts. It is accomplished by forcing molten metal under high pressure into reusable metal dies. The process is often described as the shortest distance between raw material and finished product.

“gravity die casting” refers to castings made in metal molds under a gravity head. It is known as permanent mold casting in the U.S.A. and Canada. What we call “die casting” here is known as “pressure die casting” in Europe.

Aluminum Pressure Die-Castings

Aluminum is commonly employed in pressure die-casting, but is prone to cracking or shrinking at high temperatures, so it is often alloyed with copper or silicon. Combining aluminum with these metals greatly increases its hardiness and fluidity. Since it has high dimensional stability, aluminum is used to create components with thin walls and complex shapes. Due to its corrosion resistance, aluminum is also beneficial in components that will face exposure to thermal or electrical energy.

Aluminum castings are lightweight and able to withstand the highest operating temperatures of all die cast alloys.

Aluminum Alloy Characteristics:

· High operating temperatures

· Outstanding corrosion resistance

· Lightweight

· Very good strength and hardness

· Full recyclability

Aluminum’s strength, corrosion resistance, and heat dissipating properties offer mechanical designers significant advantages. And our proprietary Thin Wall Aluminum Technology has made aluminum die casting an option for even more applications.

Advantages of Aluminum Die Casting：

One of the most significant benefits of aluminum die casting is that it creates lighter parts—with more surface finishing options than other die cast alloys. Aluminum can also withstand the highest operating temperatures of all the die cast alloys. Moreover, cast aluminum is versatile, corrosion resistant; it retains high dimensional stability with thin walls and can be used in almost any industry.

Aluminum Die Casting Applications:

· Aluminum castings improve automotive fuel efficiency by contributing to weight saving requirements

· Aluminum is used in a broad range of networking and infrastructure equipment in the telecom and computing industries because RF filter boxes and housings require heat dissipation

· In handheld devices, aluminum castings provide EMI/RFI shielding, rigidity, and durability with minimal weight

· Because of aluminum’s excellent electrical performance and shielding properties, even in high-temperature environments, die cast aluminum is ideal for electronic connectors and housings

Zinc Pressure Die-Castings

Zinc pressure die casting is a relatively easy process as it maintains high strength at room temperature, but can be alloyed with aluminum to further improve these qualities. Zinc has a lower melting point than aluminum and is suitable for hot-chamber casting. It is also valuable in the manufacture of products that require high precision and sturdiness, such as connectors and gears.

Zinc alloy characteristics:
