Aluminum is to choose the metal parts manufacturing vehicles light weight, aviation and transportation industries. Casting liquid aluminum alloy in metal mould of system like gravity, low pressure and high pressure die casting is a kind of economic way to make difficult shape, this need minimum processing. Australia’s auto industry provides a large local die casting parts, including business, manufacturing, piston and cylinder engine index of condition all can, etc.

In the car market demand, the production of aluminum die casting parts great opportunity and challenge, hope the Australian business become a global player. Through a partnership, nissan and ford, casting development and production of the new and the latest technology, our partners benefit product. In these skills created the IP, has the edge of commercialization.

Increase the production of high pressure die casting time reduced to the cycle of 30%. Cycle time has been reduced by 20% or more, in some parts of the two industry partners plants. The project includes recognition place may decrease, cycle, and do very practical results show research. It must include the workshop participants to implement the changes needed in the system. These lanes are generally a day for real change and production and the cooperation between the workshop participants become possible to achieve goals.

The project has already seen in the third year of the true spirit of research and industry partnerships, through the latest research results in the innovation has been completed the scene and practice help and support of ford and nissan’s employees. Once the test of the test of change during have been incorporated in the production system to reduce cost reduce the benefits of each part is made. One example is to reduce the time in nissan in a gearbox side cover in the double cavity mould has after months of the success of the results, at the beginning of the cycle time 75 seconds to 60 seconds. Although research in ford in the replacement of a housing casting, already successful implementation of the cycle time from 90 seconds invested 74 seconds.

In the future time cycle will try to reduce the other parts, etc.

Automatic failure detection in aluminum casting:

This includes developing a system to detect the surface and child surface defects.

A fully automatic failure detection machine vision was casting production process and prototype in the local factory extended in online test. This is the third year of the program, it puts forward the good result. The results, the design and development of the corresponding algorithm, in 2 nd years has been put to the test. Through the prototype actor team have a working system design and development casting vision. This can be the difference between good and defective parts.

The prototype system has been implemented ability test hole hole this complex casting jam. Weaning process have also prepared will test out in tears and cold of the castings of structural pan ford.

Nissan in their work the cover of the pump casting molded in vision online fault detection process. The process can be in image and found some types of defects in the surface of the part. The project had shown that, in the application of machine vision for aluminum die casting error can be converted into project stage to a working prototype success. The next step is to put the concept multilevel single grade process can more complex shapes and surface. The results will be the future commercialization a strong contender.

Die Casting/Zinc Die Casting

The casting is one of the oldest program do metal. Many products are formed using this method. This is to share knowledge gap.

The casting is four types: sand casting, permanent mold casting, casting, die casting plaster. All these types of castings have their own advantages and disadvantages. According to the properties of the product, casting is selected. Reward

Sand casting, sand casting is the oldest of the top of the casting. The method USES the cast since 1950. The quality of a material of products used in casting sand depends on. Given a successful end products processing. Usually iron, steel, copper, brass, aluminum, magnesium alloy often include lead, zinc, tin use.

Permanent mold casting: permanent mold casting with two piece mold. The mould in together, molten metal mould. This is the wool stoma hot metal is to let its cooling and module are separated. Many products are metal extruding, all be ground or manual flash. Tin, lead and zinc general molding with this method.

Gypsum plaster cast casting: one of the most simple method. Whether it is used for low melting point metal Coper, zinc, aluminum like. This is the most simple process, because mould can make easily under the condition of the brake program.

Die casting: die casting is introduced by the molten metal into the mold in high or low pressure. Only through the low pressure casting earlier but now high pressure die casting is widely used. Mould design well for complex products and amazing accuracy and successfully completed. They is made from high quality steel steel with high melting point. These mold can be repeated use of thousands of times. Casting a hollow, produces only a single component, many of the same parts produced cavity repeat, mold production unit and the combination of different parts of the death of produce different……. Usually zinc, copper, aluminum, magnesium, lead and tin alloy wax to die casting.

We can use the die casting the product, the product is pore-free allow gases through them, and they will be strong. Two types of machine is used for die casting. Cold stands for it-and hot-it die casting.

Hot-it used for high-metal die-casting fluidity. First the molten metal is collected use goose neck and then shot into the mold. Metal The advantage of the method is cycle/minutes are increased. But the shortcoming is high melting point iron and aluminum metal pick-sup particles.

Cold room die casting is used where hot-it can’t use. In the process of molten metal to transfer to the syringe is then injected into the mold metal. High melting point metal can use this process and died only weakness is hot-than it slow process.

Aluminium Die Casting/Zine Die Casting

Sand casting is a process, it is used for manufacturing or the production of large components and equipment by brass, aluminum, iron and copper. Metal melting, then gently first poured into a mold, it consists of sand.

On the beach chamber is the following method. The ideal mode is by the wood or resin any shape, the caster to part the result of the sand. In rare cases, this model can be made of metal. This model is placed in a hole in the sand. Cavity is usually live in a bottle is box like. This model and crowded into wet sand. The shape of the model in the sand reserves in the box. A person do for sand will also create a mouth reservoir, called take extra molten metal can flow. The second is the upper part of the mould for sand casting in the same way.

Mold is usually composed of two parts. The upper is known as the bottom of the mould processing and was known as the resistance. Line, the space above and below, known as the boundary. Sand and core part of things, print fill in the handle. In pouring process and the core is close to the parting line. The upper part of the pattern is joined to the resistance and frosting. These methods, help to sand compact, known as mechanics and vibration method. The following the have a separation process, involving young processing and resistance. Model is also removed with utmost care.

The main idea is to remove the pattern did not cause any damage to the cavity. After molten metal poured in cup pouring material. This is a part of the process, pouring, which provide a molten metal mould cavity. Pouring process has a vertical section, it is combined with pouring cup, this is called the materials. The runners are part of the fence and the level of multiple joints connected.

Have to lengthen the casting process, vents. The spout do the job offer a line of gas, are being built, the air, the migration to the atmosphere. Cavity size is by a is slightly bigger than a piece of ideal to make metal contract for metal cooling temperature solidification, there is normal.

When they have a chance metal solidification and cooling, mould open and remove metal parts. If there is a successful sand casting, the new part should be closely replicas of the model. There may be little line defect must be removed with a file or grinder.
