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.

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.

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

Testimonials

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

Polyethylene


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.

Semi-Precious Stone Earrings–A Fresh Alternative

Color in jewelry enhances a wardrobe, but if you don’t want to wear costume jewelry–or if you cannot wear it due to metal sensitivities–consider fashion jewelry.  And not just fashion jewelry–handmade fashion jewelry with natural elements.

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.

Zinc Die Casting

Zinc Die Casting

We have been in the foundry business since 3 generations and are proud to keep this going. Our chairman Dr. Dinesh Patel founded the company Dr. Dinesh and Ramesh Eng. Pvt. Ltd. in Ahmedabad. The company covers a space of 10,000 sq. yards (comparable to cricket field) which is only 40% utilized giving us an undue advantage for growth. We have had several metal castings (Cast Iron, Stainless Steel, Aluminum) catering to International and Domestic Companies like Ingersoll Rand, ABB, TVS and many others. However, since a decade we have shifted our focus primarily on Aluminum Castings producing from 0.5 kg to 100 kg in permanent mold. We have been adding new processes such as 

a) GDC (Gravity Die Casting)
Gravity Die Casting is the process of pouring liquid metal using Earth’s Gravity and hence it’s name. This method started on our end based on our customer’s demand leading us to develop a very difficult casting weighing almost 70 Kg in Permanent Mold for a German Company. Very few foundries can design this size of casting much less make it export quality. We are proud to say that soon we designed another such casting thereby establishing our niche in higher weight category giving an undue advantage for people with quality requirements in heavy castings. 

b) Tilt Pour
In order to satisfy the demands of our customers from around the world as well as in the domestic market we developed the Tilt Pour technology providing, engineering as well as aesthetic parts. Due to our in house building of the machine we have significant control over machine. This helps to significantly improve the quality and speed of casting manufacturing as the functioning of the machine can be customized over several parameters. Final result – better lead times and consistent quality. 

c) LPDC (Low Pressure Die Casting). 
Our goal is to keep on adding newer technologies and keeping in line with this principle we added the LPDC technology to our belt. Often when X-ray quality castings, dynamic movement (high r.p.m) is a requirement or some other quality standards dictate the usage of LPDC. 

In terms of our production capacity we have 
Production Capacity: 2000 tons per year 
Melting Furnances: 2
Holding Furnance: 5

Plastic Chair Mould

Plastic Chair Mould

Plastic Chair Mould is needed every where on the world, but how ti purchase a good quality plastic chair mould from China mold companies  is not easy thing, normally all of  China Mold Makers can make Chair mould, but you need ti need to very carefully  to select your supplier,Please ask below questions to the mould company to see if they are good or not.

Quality points we need to take careful during Chair Mould Making

1, Can you tell your chair mould running cycle time?
If the cooling water temperature is from 8 to 12 centigrade degree, if the chair weight from 1700g to 2400g, the cycle time should be 35s to 50s. If the machine plastic melt and injection is with accumulators. Please check how they make the cooling channel? If the cooling channel is extra in and out? If the cooling channel is one according with the chair shape?
2, How you guarantee your chair mould run shorts?
The guarantee for a mould runs 1 million shorts without any flashes? Because if you accept to cut the flash by your workers, I think you can use this mould for 10 millions shorts. So you need to check the steel hardness, and in the mould if there is any parting area were welded. Normally the steel hardness should be HRC33.

3, How you make the parting line finishing is good, if there is any sharp edges?
Sharp edge on the chair is dangerous, in order to avoid the sharp edge, we have to do many points during the chair mould manufacturing.
– Chair mould parting design is correct or not.
– The chair mould cavity and core thickness is enough or not.
– How you make the CNC milling the cavity and core? Normally, we need 3 stages finishing. From rough milling to steel hardened, after hardening, take the 2nd stage milling, we call it half precise milling, normally we leave 0.3mm, Then make the steel stress releasing, after this we do final precise milling. When in this time, the machining operation is very important.

1). we have to use cooling on the milling area. 2). we have to be sure that each cutting, the depth will not bigger then 0.08mm. All these are because of the steel will be deformed when milling and after the hardening. The deforming will cause the cavity and core’s fitting are not accurate, there will be a lot of hand works on it. By hand works on the parting area, you can never work out a perfect parting line.
4, the wall thickness is even or not.
Hand working on the parting line also be one of the reasons for wall thickness is not even. Of course, most of the reason is from the plastic chair 3D design and poor polishing on the cavities and cores. So when we start a plastic chair design, we have to consider the wall thickness. Some time, we need to make some area a little thicker to be sure that the chair is strong enough. But we have to consider seriously when it is need. because the uneven thickness will caused the injection not balanced and also will caused the cooling time not even. This will affect the injection speed slow down and also will cause the shrinkage marks. If the CNC milling is too rough, you can never get a chair with thickness even.
5, how about the stackable?
When the chair plastic designs are doing, we have to check its stack ability. And you also need to consider the deform possibility of the chair molding.
6, how you can make the Plastic chair mould with less weight but strong enough?
When starting makes the plastic chair design, we have to consider the weight and the strength. You can make the bottom area be strong enough by add more ribs. But how about the leg, backrest and armrest area? For this reason, you need to calculate or analyze the force of each area…in order to make a light chair strong, you can choose a very low MFI PP material. But in this way, you need to make the mould very strong and also you need to be sure the injection filling are available, as because you are using a material with MFI 4 or Max. 6.
7, How to make the air venting on the chair mould backrest?
For some chair backrest design is very complex, there is a lot of material jointing line, and some air cannot venting out when material filling and flowing. For this reason, you need to analyze by mold-flow maybe, and there are a lot of area need air venting built in the chair mould.
8, how to keep your chair mould finishing long lasting?
In order to make your chair mould cavity and core will not be rust by the plastic material, you need to be sure that the steel are high chrome and also the hardness are bigger then HRC33. If you will use some recycled material for injection, you need your chair mould be hard chrome plated. Otherwise, you need to make the polishing from time to time.

HYX  is the leading plastic chair mould manufacturer in china, we has developed more than 300 sets chair moulds during these years. We are also professional in PC transparent chair mould gas injection. If you need a high speed, long time and nice finishing chair mould, please come to us. We are sure you will be satisfied.
