Porosity in Die Casting Parts
Porosity in die casting parts. Die casting porosity is an unwanted result brought about by poor handling and method. It would be unclear until you know the meaning of die casting. Die casting is a technique or process of pushing an ample amount of molten material such as metal, plastic or resin into a container then pushing it with great force in a mold until it cools down and takes its form. Usually, metals used for die casting are non-Ferrous metals, or those containing no Iron, because Iron promotes oxygenation and rusting of the metal. The most ordinary metals used are magnesium, copper, zinc, lead and aluminum. Porosity in die casting parts is the presence of large bubbles of air inside the molded material, which makes it easier to break up. Porous die casted materials are commonly regarded to as something with low class and low quality.
Is there a way to reduce the occurrences of porosity in die casting parts? Fortunately, there are a few simple ways to be able to reduce and even eliminate the chances of having porous results in die casting. First of all, you need to conduct check-ups on your machines on a regular basis. Crevices and chinks on the surfaces of your molds allow air to seep through the machine, causing air bubbles within the plastic and metals. You can easily fix this problem by sealing it up with a sealant and cleaning it. Another thing you need to consider is to replace your molten materials with ones which have higher quality. The less cohesive and pure your metals and resins are, the more likely will it cause air bubbles inside.
Manufacturing Aluminum Hardware Handles
Manufacturing Aluminum Hardware Handles. When it comes to manufacturing, one of the best metals to use in certain parts and products is aluminum. This metal is ideal because it is relatively easy to acquire, hence it is cheap. Companies can mine them almost everywhere. Not only is aluminum cheap, its characteristics are of high quality. This metal is comparable to steel when it comes to strength and durability. In terms of weight, aluminum is also significantly lighter than steel as well. This is why it is used in making hardware handles.
Aluminum Hardware Handles are designed so that it can take high amounts of punishment. It is used to be pulled, pushed, turned and takes much abuse in order to open doors and other entry ways. In using Aluminum Hardware Handles, manufacturers can be sure that it will last longer compared to other materials because of its characteristics. And by using die casting, they can also produce them faster and with better consistency.
The manufacturing process known as die casting uses heat and pressure to make the parts or products, in this case, Aluminum Hardware Handles. The process starts with the raw aluminum, it is then subjected to an intense amount of heat in order to melt it. The liquefied metal is then injected into molds where its cavities give its shape. Using pressure of up to 30,000 PSI, the liquid metal is forced into every nook and cranny of the mold. After the mold cools down, the resulting Aluminum Handles have accurate dimensions, consistent and with great surface quality.
Manufacturing Returning From China to California
CP Lab Safety was worried about escalating product costs. So it decided to move its manufacturing overseas — to California.
After more than seven years of using a contract manufacturer in China’s Guangdong province, the Novato company this spring shifted production of its Eco Funnel and some 80 other products in its portfolio to Wright Engineered Plastics in Santa Rosa.
It was a no-brainer for CP Lab Safety CEO Kelly Farhangi: “In the U.S., you can manufacture on a cost comparable to China.”
Companies are “reshoring” manufacturing — even to California and the Bay Area — for reasons that vary as widely as the types of goods returning to American factory floors.
Four Northern California companies in the past five months have reshored products from China to Wright Engineered Plastics, said President and CEO Barbara Roberts. Their reasons range from costs to vicinity to market and from quality to finance.
Chinese manufacturers, for example, won’t ship until a product is completely paid for, Roberts said, and then transportation could add another 30 days or more.
“That’s a double-whammy,” she said.
This is not your granddaddy’s smoke-belching, middle-class-securing manufacturing, but domestic manufacturing advocates say it represents an opportunity for jobs in a down economy.
“At the end of the day, everything else being equal, it’s always best to manufacture near your markets,” said Ken DeWoskin, a senior adviser at Deloitte in China. “But everything being equal has a lot of questions.”
Those swirl around a host of global economic factors like labor quality, cost and overall productivity as well as an unfolding regionalism — shaped by free-trade agreements and common currencies — that puts more emphasis on the proximity of supply chains.
“With the U.S., Mexico, into Central America and South America, you can integrate supply chains even more and at the expense of China-U.S. trade,” DeWoskin said.
Even then, whether it makes sense to reshore manufacturing depends on the product, he said. The supply chain for consumer electronics, for example, is well established in China.
It may make sense, however, to get components from other markets and site final assembly closer to a company’s market, DeWoskin said.
That’s precisely what Tesla Motors looked at when the San Carlos electric car maker opted to ship assembly of its battery packs from a pilot plant in Thailand to California. Those nearly 7,000 lithium-ion cells continue to be made in Japan and Korea, but it didn’t make sense for the assembled packs to sit on a ship for 10 to 15 days, said Diarmuid O’Connell, Tesla’s vice president of business development.
“Is it more expensive in some respects — in real estate and labor — to assemble battery packs in the U.S. compared to some other overseas markets? Yes,” O’Connell said.
But moving assembly close to Tesla’s R&D operations “makes a lot of sense,” O’Connell said, as the company continues to develop and make changes in its technology.
That plays into the thinking of much smaller companies, like Farhangi’s CP Lab Safety, as well. Although it continues to make the molds for its products in China, where Farhangi said there are significant engineering cost savings, the company can make production changes quickly by using a domestic manufacturer.
Whether more companies reshore manufacturing in California — as opposed to another state, Mexico or South America — is largely in the hands of policy makers, said Gino DeCaro of the California Manufacturers & Technology Association.
“California needs to show a deep understanding of manufacturing. We need an analysis of what policies will do to the manufacturing community in the state,” DeCaro said. “That would be a big signal to companies that have looked to California in the past and seen uncertainty.”
Why manufacture in China?
* Shipping costs are at a three- to four-year low.
* Integration of supply chain, especially for products like consumer electronics.
* Labor costs remain cheaper than in the United States.
Why manufacture in the Americas?
* Closer to American markets.
* Integration of supply chain, potentially for things like auto assembly.
* Ease of making changes to orders.
* Time. Products don’t sit on boats for weeks or months.
* Cash use. Chinese manufacturers can require full payment before shipment.
* Strength of currency. As the dollar weakens, the underlying cost advantage of China may dissipate.

What is Magnesium?
What is Magnesium? It is usually depicted as a metal, second only to steel and aluminum in popularity. Aside from that, people don’t know much more about it, even though it has so many uses. So, what is magnesium?
Magnesium, with the chemical symbol Mg, is the ninth most abundant element in the universe by mass, and eleventh within the human body. Its many applications include making components for electronic devices, photoengraving plates for printing, paper manufacturing, and fireproofing wood. Ever heard of mag wheels? Those shiny high-grade car wheels which guys usually drool over in auto shops? They’re not called that because they’re always featured in car magazines – their name comes from what they’re made out of, which is magnesium.
One of the current major uses of the element is in die casting. Because of its light weight, magnesium is one of the most commonly used metals for this purpose, as compared to zinc and aluminum.
A lot of compounds can be made with magnesium, and these compounds, along with magnesium in its purest form, are used over a wide variety of industries. What is magnesium? It is a very important and useful element – it’s not just a third place metal behind steel and aluminum.

Aluminum Manufacturing in Die Casting
Aluminum is widely used in die casting because of the properties that it possesses. Aluminum is useful even in everyday life because that is why die casting companies produce die cast parts made from this alloy. Aluminum alloy is lightweight and has good corrosion resistance. It can also take high temperatures so the things that need to be heat resistant are usually made of aluminum alloy. The things that also need high corrosion resistance and electrical conductivity are made of aluminum. Due to its high dimensional stability, aluminum alloy is used to make thin walls and complex shapes.
Aluminum part types can depend on the combination of alloying elements such as silicon and copper. Zinc can also be used as alloying element to aluminum. The combination of the properties of the different alloys allows the production of high quality products. Silicon increases melt fluidity that is why complex parts such as connector housings and thin walls are made of aluminum with silicon. When copper is used as the alloying element, the part has increased hardness and decreased ductility.
Aluminum part types can be differentiated on the amount of alloying element present. Aluminum types are Alloy A380, A360, A369, A390, A413, and A518. They are series of aluminum alloys so expect to see alloy types with decimals. The Alloy A380 is the most common aluminum alloy used in die casting. Lawnmower housings and gears are usually made of AA 380. Escalator parts and conveyor parts are usually made of Alloy 518. Parts that need high corrosion resistance are made of Alloy A360.
Parts differ in the content of alloying element that makes the aluminum part types. They also cater to the different needs of the consumers and the producers as well. These are the most common Aluminum Alloy Types.
