Tips on Maintaining Tooling Made for Die Casting
Tips on Maintaining Tooling Made for Die Casting. Die casting assemblies are recommended for large-scale metal working. Because pressure is applied on molten metals, which cool pretty quickly, may products can be processed in a short period of time. A company must be sure that its tooling made for die casting is in optimal conditions. This will help avoid malfunction of the assembly or factory defects like excessive porosity.
The die casting process involves two die molds: the cover die and the ejector die halves. Molten metal is injected through an opening in the cover die. Once the product has solidified, it will be released through the ejector die half. Always check if the ejector pins on the ejector die half are working. They are used to push the product out of the mold.
Fluid lines are also important tooling made for die casting. Waterlines supply the system with water as coolant and lubricant. This will increase the number of cycles per hour. The vents should also be clear, so that gasses can easily escape during casting. If gasses are trapped during the rapid casting process, there are risks of forming large air bubbles. This will cause porosity and tensile weakness on the final product.
Finally, be sure that you are equipped with trim die tooling made for die casting. This is particularly needed for aluminum processing assemblies. The trim die removes excess aluminum, which are imperfections from the casting process. It helps in producing a finer surface finish. The scrap aluminum can be recycled for future castings. Hence, it will save production costs.

Minimizing Porosity in Die Casting Parts
Minimizing Porosity in Die Casting Parts. Die casting is popular method for machining metal parts for vehicles and electronics. When this method is applied, tough and well-detailed products are produced. However, due to large capital costs of the dies, die castings are preferred only for large scale operations. One important issue in this industry is the tracking of porosity in die casting parts.
In order to understand the concept of porosity in metal working, one must first understand the basics of die casting. Hot or molten metal is forcefully injected into a cavity, at pressures from 10 to 175 mPa. The cavity is then applied with that pressure until the metal freezes or solidifies. The mold cavity is made by two contacting parts: the cover half and the ejection half.
The pressure of injecting the molten metal results in high processing speed. It also induces uniformity, inside and out, of the finished product. However, air in the injection tube mixes with the molten metal during this speedy process. The trapped air bubbles in the product are called porosity in die casting parts. This is often considered a factory defect. If the bubbles are large or interconnected, they can cause loss of tensile strength in the final product.
There are several factors that affect porosity in die casting parts. The manufacturer must be sure that the molten metal is free from impurities and that the molds are clean. The working temperature of the furnace must also match with the metal being processes. Other factors include shot speed, lubrication and amount of pressure.

Cold and Hot Chamber Casting for Motor Vehicle Die Cast Parts
Cold and Hot Chamber Casting for Motor Vehicle Die Cast Parts. Die Casting is an important process in the metal working industry. Do you that most of the parts of your car are motor vehicle die cast parts? Depending on the type of metal used for that automotive part, either cold chamber or hot chamber is casting to machine them. The products include sprockets, rods and gears. Basically, die casting is performed by injecting molten metal into a cavity. The cavity is the shape formed by two dies. Then, this is applied with pressures up to 175 MegaPascals until the metal solidifies. The effects are high yield strength and resistivity to multi-directional fatigue.
Naturally, customers want their automotive parts to be cheap, durable and with a high quality finish. These specifications are easily achieved through automated high pressure die casting. Most of the detailed aluminum parts are motor vehicle die cast parts. Traditionally, sand casting is used to shape car parts. However, sand casting is limited to one piece per mold. Usually, the sand mold is destroyed after one product solidifies. Hence, there are higher production times and costs.
Cold and hot chamber casting for automotive industry solve these problems. It resulted in higher production times and lower post-machining. Pressure die casting results into high yield and smooth finish, which requires little sanding or grinding. Cold processes work on high temperature melting metals, like aluminum and zinc. Hot chamber processes involve weaker metals that can be shaped into gears or one-piece gear trains. Motor vehicle die cast parts have high tensile strengths and are perfect for motors and transmission.

For Large Scale Industries: The Process of High Pressure Die Casting
For Large Scale Industries: The Process of High Pressure Die Casting. The process of high pressure die casting is popular among large scale production lines. It is considered as one of the most cost effective and fastest metal working process, when compared to forging, sand casting and other types of machining. Traditional die casting is also called high pressure die casting because the molten metal is forced into the mold cavity by using high pressure.
The mold cavity is formed by two halves. They are the cover die and the ejector die. The section where the two halves meet is called the parting line. During casting, molten metal is injected between the dies. The metal is allowed to flow through an opening in the cover die half. High pressure, between 10 to 175 mPa, is maintained until the molten metal solidifies. This process of high pressure die casting ensures uniform solidification of the final product. Hence, it produces uniform work pieces with high yield strength. There are two types of the method: cold chamber and hot chamber casting. The choice depends on the melting point of the metal. For example, zinc and aluminum alloys can only be processed in cold-chamber environments.
The process of high pressure die casting has many applications, ranging from the toy industry to automotive and computers. The technique also minimizes, if not totally eliminates, post-machining like sanding or grinding. Therefore, there are less post-production costs. However, this technique is only recommended for large scale businesses. The initial cost of construction of dies, due to painstaking details and strength, is relatively higher than other machining processes.

Metal vs. Plastic: Die Castings Used for Audio Speakers
Metal vs. Plastic: Die Castings Used for Audio Speakers. Examine your sub-woofer speaker closely. Can you tell if it is made from aluminum or plastic? Aluminum die castings used for audio speakers are a popular application of die-casting as a machining procedure. These types of speakers are very similar with plastic-built ones, and they have several advantages too.
Many speaker brands use plastic as frames and fixtures of their speakers. They are shaped through soft molding, where molten plastic takes the shape of the mold. Plastic is desired because it is cheaper and easy to manufacture compared with metals. The market patronizes plastic-built speakers because they are light and easy to carry around.
However, there is a recent problem with plastics in terms of toxicity and recyclability. Hence, die castings used for audio speakers have become more popular. Aluminum is widely used for speaker frames and internal fixtures. Plastics need several treatments for them to be tough. They need plasticizers and conditioners. Aluminum, on the other hand, is already tough and durable by itself. Especially because it undergoes cold-chamber die casting, aluminum speaker parts exhibit low brittleness and good elasticity. It fights on par even with the best treated plastics. Aluminum is also very light.
Aluminum die castings used for audio speakers are made from high pressure molding. The molten aluminum is injected to a pair of dies. Then, pressures of 10 to 175 mega Pascal are applied until the shaped metal solidifies. The resulting product is stiff and non-toxic, and it is easily recyclable. Just disassemble it and it can be processed again.
