Aluminum Die Casting

Aluminum Die Casting Description:
Aluminum Die Casting, Die casting is similar to Permanent mold castings except that the metal is injected into the mold under high pressure of 10-210Mpa (1,450-30,500) psi . This results in a more uniform part, generally good surface finish and good dimensional accuracy, as good as 0.2 % of casting dimension. For many parts, post-machining can be totally eliminated, or very light machining may be required to bring dimensions to size. die casting,aluminum casting can be done using a cold chamber or hot chamber process.

Plastic injection molding industry


As a result of developments in molding machines and mold making machinery, there will be a trend to create both larger and smaller sized plastic mold.overmolding. 2k molds.

Molding machine producers are making larger machines to accommodate product designs that were not possible before because of

Overview of the Industry 5

molding-machine overall size restrictions. Products for example, automotive fenders and wraparound bumpers will certainly be made on machines that are the size of small houses. The much more this is done, the much more it will push makers to construct bigger and bigger machines. Obviously, each injection molding machine needs to have a plastic mould. So the injection mold will be developed larger and larger to accommodate product size needs.

On the other hand, innovations in materials and developing systems have resulted in the manufacturing of small parts that previously were not candidates for injection molding. Products such as small electrical connections and very small medical valves are now being developed. The tolerance needs and small dimension of these kinds of units require very precise, sophisticated molding machines; these are being developed now in sizes that will suit on the top of an ordinary desk. The molding machine tool suppliers are aiming to construct even small machines as the need boosts. So, the mold for these kinds of molding machines are also smaller and smaller. There are plastic molds now that can suit the palm of a human hand, and the trend is toward even smaller molds to fit near future goods demands.

Lead Times

Lead time is defined as the total amount of time demanded to obtain a product, from order to end up item. Simply put, the time scale for a plastic mold extends from the time a purchase order is gotten by the China mold maker to the moment the mold is delivered to the company purchasing the injection mold. A typical lead time today varies from twelve to 16 weeks for an average mold. (This does not include time to correct the injection mold issues or try it out in a manufacturing environment.).

A lead time of twelve to 16 weeks may not look like much to individuals who have been in business a while. As a matter of fact, it is a great renovation over what dominated before. In earlier days, the lead time may have been 33 weeks or much longer. Nonetheless, in today’s competitive surrounding, lead times are important because they dictate when an item can get to its market. The earlier the product could be presented, the faster it can begin bringing in gains, and the faster the business can begin spending those revenues in new product project.

There are numerous ways to minimize lead times, and many are being certainly pursued today. Particular of these promise to bring lead times down to unheard-of numbers:.

Computer-generated data. Computer systems allow China injection mold maker and product designers to work closely all together even though they are in different towns, states, or countries. As computers become faster and more powerful, and as computer programs become more versatile, product designs can be generated and checked faster, and the same data may be.

6 Plastic Injection Molding.

used to produce the mold. Indeed, these kinds of factors may be carried out as parallel efforts so the mold can possibly be launched before the item design is even ended up.

injection mold materials. The typical method has been to use state-of-the-art mold steels to create the cavity and core of the injection mold. However, new metal alloys and upgrades to present alloys are allowing the injection mold to be constructed faster and weigh less. One material that will be used largely is aluminum. Aluminum is now used mainly for ptoto molds, but advancements in the material alloys and approval by moldmakers has made it feasible to use aluminum alloy in numerous production injection mold cases. Beryllium copper material, brass, soft steels, and even plastics like epoxies are being utilized an increasing number of in an effort to reduce lead times for creating molds and thus get products into the marketplace faster.

Making use of these aluminum alloys and new computer tools and programs can drastically lower lead times. Sometimes, lead times have been decreased from the ordinary 12 to 16 weeks to just ten days. And the technology will soon be readily available to carry it down to only a few hours.


Advances in plastic resin have been profound. In 1995, there were approximately 18,000 different materials available for injection molding. These are increasing at an average rate of 750 per year. Most of available materials are alloys or blends of previously developed materials, and a part developer will possibly be able to select from them a material that provides specifically the right properties for a specific need. Again, computer systems enter into play since the designer can not possibly read through the property values of all those materials in a practical amount of time. The computer can do it in a few secs and will list the plastics that meet regardless of what standards the designer requires. Then the part designer can decide from just a few resin rather than 18,000. But even if a precise material match does not exist, the designer will be able to call on a compounder to put together a resin that does exactly fit the requirements. Obviously, that adds an additional material to the list of 18,000, and that’s how the list progressed in the first place.


Recycling will keep on be a major issue in the future, as it is today. Consumer approval of products made from recycled plastic material will enhance, making it more profitable for firms to develop such items. Technological advances will make it easy to separate discarded plastic products so they may be properly recycled. Advances in machinery and material.

Overview of the Industry 7.

ingredients will allow mingled plastics (that can not be separated) to be used in products such as parking lot bumpers, picnic tables/benches, and water-sport products such as boating docks. Some of these products are available today, but with future advances, they can be sold at more competitive prices, and their availability and use will grow. Products will be designed with recycling in mind so they may be easily dismantled and identified for material content.

Aluminum die casting and its importance in Aerospace Industry

Aluminum die casting items are of remarkable use in different industry sectors and more so in the aerospace engineering where precision and top standard items are of greatest significance. These items are used in building both little as well as the big components in the aviation industry. Additional, die casting aluminum is used both in the pivotal military sector as well as commercial. The reason for this is easy – they are cost-friendly solutions and provide amazing outcomes.

Apart from being cost-effective, the parts made from die casting aluminum are additionally prepared to endure extreme weather situations and increased damages. Another vital reason for using aluminum products in aircraft is that the meal is comparatively affordable than other metals that are die casted. Additional,  aluminum has the potential to get with other metals in order to provide durability and much flexible.

With aluminum casted products, you do not have to compromise on the standard yet can them at much affordable production cost. Further, all the standards that have been set for using metal components, aluminum relax the need to the utmost. Hence, they are certified secure for use in planes, affordable and have all the qualities that are needed for flying crafts. So casting aluminum is on the boost like never before. Further, the top thing about an aluminum die cast part is that its weight is favorable for the aircraft works.

So, how actually is casting Aluminum done and what are the processes involved? Well, the reply is simple. Aluminum alloy is first forced into top-grade steel at high speed and force at high temperatures. This outcome in superior standard products that are very light and thin-walled perfect for use as aircraft components.

 It is to be mentioned here that Aluminum die casting is a hard technique. Only a truly experienced and top standard team of engineers can make sure that the parts come with top volumes or with excellent tolerances and surface finish. Actually, this type of force casting is far more famous than gravity die casting or sand casting. This is because the need for machining is this type of weather for Zinc or aluminum casting is extremely low due to the close casting tolerances. Though the tooling cost in casting Aluminum or rather any metal is considerably higher than the other 2 types yet, the mechanical properties achieved thus are far excellent in terms of functionality.

Engineering service contracts can cover a wide array of support from custom design projects and, no matter which option you choose, Ashland provides hardware and technical support designed to fit your needs.

Flow Modeling Process  for sand casting china company and aluminum die casting parts

The Arena-flow™ software models both phases (sand and air) of the core-making process. Capabilities include:

  • Three-dimensional multi-phase computations
  • Highly accurate simulation of both air and sand particle flows
  • Analysis of the airfield on a grid
  • Discrete analysis of 250,000 to 1,000,000 sand particles
  • Interfacial drag coupling of air and sand particles
  • Proper wall restitution to ensure accurate particle deflections off of tooling surfaces
  • Computational consideration for sand reaching “close pack” maximum achievable density

Postprocessing Capabilities 

The analysis tools found within the software allow the user to analyze the entire core-blowing machine and process through:

  • On-screen rotation, zoom, and slicing
  • Analysis of core-making variables such as particle volume fraction, core density, and pressure
  • Analysis of additional variables including particle velocity, air velocity, and vent/blow tube performance
  • The display of user-specified parameters
  • Querying of process data
  • Automatic animations

Arena-flow gives you the capability to understand the entire core-making process, including what happens in the sand magazine, blow plate, blow tubes, and core cavity. Arena-flow also allows you to capture and analyze data relating to the performance of various parts of the process including individual vents and blow tubes.

Tested and Proven 

Arena-flow™ technology was developed by Arena-flow, LLC of Albuquerque, N.M. along with General Motors, NASA, the Department of Energy and Auburn University.

Experiments conducted by General Motors using a production core blowing machine for cylinder block water jackets have been used to validate the software. Computations from Arena-flow simulations corresponded closely with measured pressure response at locations throughout the core box, blow plate and sand magazine, including “spikes” in regions where blow tube “fill in” occurs. Time-to-fill was also predicted accurately by the software.

Since the work conducted over two years ago by General Motors, Arena-flow has been validated in over twenty different core-making applications in Europe, Asia, and North America. Utilization of the software is no longer limited to foundry core-making operations. Several equipment manufacturers have utilized Arena-flow to understand and optimize the capabilities of the core-making equipment that they currently produce. Multiple simulations have shown that tooling design and process optimization cannot be conducted without an intimate understanding of the equipment involved. Arena-flow models the entire core-making “machine.”

Ashland is the exclusive worldwide sales, marketing and service supplier for Arena-flow in the sand casting industry. Arena-flow and Ashland have partnered to continue research efforts and software code enhancements with respect to gassing, purging and resin-related characteristics which have a significant impact on the core-making process. Several areas of continued research include:

  • Material Variables
  • Process Variables
  • Equipment Variables


Arena-flow has been recognized by the American Foundry Society as having “the greatest long-range significance to the metal casting industry.”

“Arena-flow approached GM early in the development of the software, and we helped fund it. We understand the value of better core box designs and higher quality cores. In working with Arena-flow, we were able to achieve a 30% reduction in the development time required to design an end core for an upgraded V-8 engine. I recommend it.”

Plyethylene Plastic Material


The Polyethylene market continues its trek higher into unchartered territory. Fundamentals supporting the market include: tight resin supply, solid domestic/export demand, and rising feedstock costs fueled by soaring energy prices. Current Polyethylene prices reflect a full implementation of the September $.05/lb and most of the October $.06/lb price increases, spot prices have now risen about $.20/lb since the spring.

Looking ahead, producers will likely continue to step up resin prices on future spot offerings as they work to enable the next $.05/lb increase recently nominated for December. Resin prices are already damagingly high and processors will resist another increase, but they are not negotiating from a position of strength. While the export market was largely responsible for pushing resin prices higher during the summer, it is new found domestic demand that is sustaining prices during the peak fall buying season.

Domestic resin buyers have generally been limiting their resin purchases and inventories hoping for price relief ahead. Polyethylene producers have also been cautious about building resin inventories at price levels above $.40/lb, these are historically high prices and neither want to get caught with expensive resin if they market were to fall.

By keeping production much in line with forecasted resin orders, producers have been able to keep the market snugly supplied without a lot of surplus resin to sell. Subsequently, the low inventory levels throughout the supply chain have created an environment where it is difficult for processors to hold out and resist producers’ price increases.

At the moment, the spot market is not flush with resin, but it can be purchased – at a price. Railcars of even low quality C&A; grades are now selling in the low to mid 50s. Railcars of good wide spec injection grade Polyethylene are mostly in the mid 50s+. Railcars of LLDPE Butene/Hexene/Octene are selling in the mid to high 50s and good LDPE clarity and EVA film grades are quoted into the 60s.

While the contract market has moved in chunks of $.05-.06/lb at a time, the spot market has moved higher in a more orderly fashion, generally rising about 1/2 cent per week. Since this trend began in the spring, when spot offers have been purchased they have been replaced with slightly higher priced offers. We expect this pattern of pricing to continue in the immediate future.

There is margin and capacity at the producer level, so it is possible to see some producers look to take advantage of the profitable production economics to achieve a market share shift. They could do this by making extra resin to sell to their competitors’ customers at discounted (but still profitable) prices. However, we have seen the producers remain very disciplined, enjoying their profits without risking the chance to disrupt the market.

During the summer, Natural Gas prices were falling and Crude Oil prices were rising which created great foreign resin demand because US feedstock costs and resin prices were much lower than their foreign competitors. Now that both oil and gas have rallied sharply everyone’s feedstock costs and resin are expensive.

Natural gas prices have nearly doubled in the last 2 months, reaching levels above $9.00m/Btu for front month November delivery, while the January contract has already traded well above $10.00 m/Btu, but prices have recently come off by as much as $2.00 mBtu. Crude oil is also off substantially from its $55/barrel level, but still at historically high prices.

These cost pressures have ethylene monomer on the rise again with traders anticipating $.40/lb offers for this important feedstock. Polyethylene producers are not ready to watch ethylene price increases erode the fantastic resin margins achieved this summer. Unless this trend of rising energy prices reverses sharply and prices really fall off, expect more Polyethylene price increases backed by the higher feedstock cost argument.

Aluminum die casting design

1.    There are a variety of casting methods to produce aluminum die casting and magnesium alloy casting, because of the low melting point of aluminum and magnesium alloy. So in the design of their structures, you should consider which kind of casting method to cast this casting at first, in order to consider the relative structural manufacturability.
2.    The aluminum alloy and magnesium alloy casting should try to use thin wall structure, and strive to the balance of wall thickness. This is helpful to prevent shrinkage cavity shrinking and improve the strength of the metal castings. But you can also thicken some part for the unbalance of wall thickness to set feeding aluminum and magnesium alloy casting. This can help filling shrinkage to guarantee the quality.
3.    The aluminum and the magnesium alloy is easy for oxidation and suction. The density is small, so as to make the static pressure of the metal fluid is small and be difficult to exhaust. Therefore, aluminum and magnesium alloy casting is easy to generate hole and oxidation slag, reduce the mechanical properties and gas tightness. So designing the casting structure should avoid big plane, and the transition should be gentle, and avoid causing the turbulence of metal liquid.
4.    Because of the low melting point of the aluminum and the magnesium alloy, to those castings that have some certain gas tightness requirements, you should avoid using core support to fixed core when design.
5.    The compression strength of magnesium alloy is higher than its tensile strength. So you should adopt asymmetrical section and box to undertake the compressive stress.
6.    Pay attention to adopting the method of double metal die casting and potting casting to solve the problems in the structural design of the aluminum alloy and magnesium alloy.
7.    The corrosion resistant of magnesium alloy is poor. Often use surface treatment to improve the corrosion resistance of magnesium alloy castings.
