Die Casting: The Definitive Handbook For All Die Casting
Our web contains everything you need to know about die casting. Die casting is an important manufacturing technology used in lots of industries. Thre are many Companies that can make nearly all parts using different casting processes. On our web, you will learn how the die casting technology may help your business.
Die Casting Definition: What is Die Casting?
According to Wikipedia Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminum, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.
The History of Die Casting
Die casting equipment was invented in 1838 for the purpose of producing movable type for the printing industry.
It was during this time that a patent was awarded to Sturges in 1894. This was after the invention of a manually operated the machine that was used for the casting printing type.
After 20 years, the technology was mainly used for tin and lead.
This was before the technique was used for other metals such as aluminum and zinc in the 1920s. Since then, there are a number of technological advancements that have been witnessed in the industry.
This includes a number of metallurgical control measures that have improved the manufacturing and processing criteria.
The technological advancements focus on the following key aspects:
1. Increasing the die casting capacity, thus higher production/short production runs
2. Sophisticated die construction processes
3. An advanced casting capability with a number of metals such as steels and brass being included in the process.
Die Casting applications
Nowadays die casting has become popular in very many industries across the globe. These include automotive, recreational, medical, alternative energy, electrical and transportation, just to mention a few.
Because of its flexibility and reliability. It’s possible to attain different surface finishing requirements.
These include complex shapes, near-net-shape, very tight tolerances, and high strength.
Applications of brass die casting
The brass die casting parts are used in application that requires extreme operational characteristics.
There are many hardware parts are made by brass die casting. Home decor hardware,
cabinet hardware, brass cabinet handles, brass drawer handles. Bathroom hardware towel shelves, brass bathroom hooks.
The high-pressure die casting produces parts that are:
Have relatively high strength.
1. Corrosion resistance.
2. Heat resistance.
3. Reasonable electrical conductivity.
4. Pressure tight (up to 300 psi).
5. Easy to polish.
Ideally, brass materials can be used in very many industries such as aerospace, automotive, chemical processing, alternative and decorative industries, just to mention a few.
Applications of aluminum die casting
This is a common alloy used to die cast products. There are many furniture hardware made by aluminum die casting, aluminum die casting handles, aluminum die casting benches.
However, it is prone to cracking shrinking and cracking at elevated temperatures.
It can be alloyed with silicon or copper. This improves its hardness and fluidity.
Due to its low melting point, it is a perfect choice for hot chamber die casting.
Applications of zinc die casting
The zinc is easy to die cast. There are many home decor hardware products are made by zinc alloy die casting, such as cabinet zinc alloy die-casting handles and knobs, zinc alloy die casting bottles.
They can be mixed with other metal alloys to improve the chemical and physical properties.
Zinc has a low melting point, this makes it suitable for hot chamber die casting.
It used to die casting parts that should be sturdy, but with high precision.
These die casting parts are used in the manufacturing and processing industries.
Applications of stainless steel die casting
The stainless steel die casting is popular in very many industrial applications.
Automotive, manufacturing, production, energy production alternative energy, stainless die casting benches, stainless steel die casting handles,stainless steel die casting containers, stainless steel die casting toggle clamps, stainless steel die casting index plungers.
Furthermore, they are used to make metal die-casting tools. This is due to the superior physical and chemical properties.
The stainless steel is used to die cast medical equipment and instrument parts. It doesn’t rust thus, the components can guarantee optimal performance.
