The Wonders of Aluminum Automotive Parts

Filed under: Aluminum Casting Parts — Tags: , — admin @ 1:29 am

Aluminum vehicle parts are manufactured in the thousands each day; these are used in so many applications in various industries. Most of the features in vehicle parts are manufactured in bulk with the “net shape” concept so the manufacturers can save from waste materials costs and additional machining labor.

The mounting holes are also obviously included in the aluminum automotive part production to save on the costs. Most of the primary (tier one) vehicle parts manufacturers are operating with their own manufacturing plants. Even then, there are still cases where they source out their purchase for aluminum car parts from die casting companies.

Aluminum like 380 Aluminum die casting, which is also known as aluminum in other disciplines is a very abundant metallic chemical element with so many uses and applications in various industries these days. Aluminum is clearly identifiable with its silvery white color belonging to the boron family of elements.

There are clear advantages of aluminum vehicle parts over the use of steel in most of today’s industry applications. Such benefits have surged over the years, particularly in car manufacturing. Many have already initiated the replacing of steel as the primary base metal used in car frames, and in other significant parts as well. Aluminum was proven over time to be much stronger and obviously more cost-effective than metal.

Aluminum is also less likely to corrode compared to steel. It can be easily molded, which would probably explain why labor costs for aluminum die-cast parts is cheaper compared to other materials used. Aluminum however is more expensive; in fact, it is about five times more expensive than steel itself.

Such disadvantage of using the aluminum material in vehicle parts can be easily written off. It should be noted that more manufacturers these days are seeing the big difference, and are starting to experiment with the more expensive aluminum material mainly because it is considerably lighter than steel, and easy to shape up. This lightweight feature surely makes modern cars faster and much leaner, helping much to achieve worldwide fuel efficiency standards. This is so since lighter cars would naturally mean less fuel would be used. You can clearly see for yourself how a typically expensive material can make up for efficiency and flexibility in its applications in the long run.

All these are the direct result of various luxury car models rolling out of production these days utilizing aluminum car frames. Although such car types are evidently more expensive than their steel car counterparts, owners will be driving such cars with relief knowing they will be able to save on its efficiency features on the long term afforded by the use of aluminum car parts. Environmental advocates also welcome the idea because of such wonderful benefits, and the added plus that aluminum itself is very much recyclable, which means the material can be recycled and used for other useful purposes.

Aluminum car parts are clearly the future. No material these days presents so much uses that helps address most issues and concerns to improve productivity and progress in the society.

Three Common Causes of Die Casting Porosity

Filed under: Aluminum Casting Parts,Cast Parts — Tags: , — admin @ 1:19 am

Three Common Causes of Die Casting Porosity. Die casting porosity is an inevitable kind of defect that metal casting companies encounter. With mass production of metal casting parts, such defect is proven to be difficult to avoid even for big manufacturers.

What is die casting porosity? Die casting porosity is the formation of tiny pockets of void spaces within a metal casting part. These spaces contain gas which was normally formed after the metal casting part has cooled down.

If you wonder what causes this kind of defect, this article will give you three common causes of die casting porosity.

1. Aggressive Mixing.

During the process of mixing hardeners and casting resins, you must avoid inducing air into the mixture. You can use mixers from Jiffy Mixer line because it is said that their machines induce less air than other mixers. The most effective way to remove air due to the mixing process is to degas or de-air the mixture inside a vacuum chamber before you proceed to pouring.

2. Injection temperature

In die casting, injection is the process when the molten metal is pushed, using high pressure, into the die or mold. If the injection temperature is too high, chances are, the die casting part will form air bubble because the casting resin will boil.

3. Cooling rate

Air bubbles within the die casting parts are sometimes caused by non-uniform cooling rate. The cooling rate depends from the maximum wall thickness of the mold, the thermodynamic properties of the metal used and also the complexity of the mold itself.

Die Casting Porosity and Its Causes

Die Casting Porosity and Its Causes. Die Casting porosity is one of the most common defects in the die casting manufacturing industry. What is die casting porosity? Die Casting porosity is a type of die casting factory defect in which the die cast parts have tiny spaces which contains air within the metal – hence, the die cast parts become porous. The porosity of die casting parts could weaken the parts itself if the spaces or voids are very large.

To clearly understand the causes of the porosity one must know the basic of the die casting process. In a nutshell, die casting process involves molding molten metal by placing it inside a short cylinder, and then a great force is applied by a piston connected on the cylinder, pushing the molten metal so it would take the shape of the die cast die or die cast mold. During this process, the metal is forced along with the air inside of the cylinder to the die casting mold.

Die casting porosity could be contributed by many factors like the following:

• Die casting machine pressures.

• Temperature of the metal and the mold.

• The cleanliness of the materials used.

• Design of the die casting mold.

• Design of the die casting part.

• The shot speed of the die casting machine used.

• Die casting mold release or die casting spray

Die casting manufacturers use metals that are non-ferrous or metals that don’t contain iron. It is because iron content is the main reason for oxidation and rusting. Non-ferrous metals include magnesium, tin, lead, copper, zinc and aluminum.

Importance of Draft Angle in Die Casting Product Design

Filed under: Cast Parts — Tags: , — admin @ 1:10 am

Importance of Draft Angle in Die Casting Product Design. Die casting, in a nut shell, is a process that involves injecting molten metal into mold cavity at high velocity and high pressure. The metal will take the shape of its mold and then ejected when it’s cooled. One of the factors that sets die casting process like the zinc die casting process apart from other metal casting process is its ability to produce high detailed metal parts with high level of accuracy, repeatedly, in relatively short amount of time hence, it is an industry suited for mass production of metal parts.

One of the key factors that affect the final quality of the produced die casting parts is the design of the mold cavity that is used during the process. It is a tricky job to design molds for die casting parts, especially when they have specific mechanical and aesthetical requirements.

One of the most important and basic requirements of any mold design is the consideration of the draft angle. What is die casting draft angle and why is it important?

Draft angle, in a simple sense, is a slope incorporated on each walls of the die casting mold. Die casting parts will easily stick inside the die casting die or die casting mold if the draft angle incorporated on its side walls was not enough.

Die casting method involves high pressure injection process in which the pressure forces the molten metal on the surface wall of the mold. It creates an intimate contact between the cavities of the mold and the molten metal hence, making it difficult for the metal cast part, when cooled, to eject from the mold.

In the end, no matter how exquisite and well detailed a die casting mold is, if it is not properly incorporated with the proper degree of draft angle, the final product may not most likely be as what the customer has asked for.

Why Draft Angle in Die Casting is a must

Filed under: Cast Parts — Tags: , — admin @ 1:04 am

Why Draft Angle in Die Casting is a must. In the process of die casting, having the right draft angle incorporated in die casting molds is a very important thing. It is one of the factors that will affect the total quality of the die casting parts produced.

What is Die Casting Draft angle?

Did you ever notice that the sides of a cupcake pan are sloped in a certain angle towards the center of the pan? If you inspect the pan, the sides are not straight but rather slanted at a certain degree. With that as an example, draft angle in general sense, is an angle integrated into the wall of a mold, making the opening of the cavity a tad wider than its base.

Die Casting draft angle is the angle that is incorporated into the walls of the die casting mold allowing the die casting part to be easily ejected from the mold.

Is draft angle in die casting tooling really necessary?

The rationalization behind the need for draft angels on die casting molds lies from the very nature of the die casting process – injection molding process -and also, the inevitable issue of mold shrinkage.

Die casting manufacturing process for metal parts is done by forcing the molten metal into a mold cavity. These mold cavities are made with hardened tools that have been machined to the net shape of the die casting parts.

The injection of the molten metal into the mold cavities is a high-pressure process. The high pressure forces the molten metal into intimate contact with the walls inside of the mold cavities. The high-pressure packing of the surface of the mold’s cavities makes it hard to get the die casting part out of the mold. In short, the ejection process will be compromised.

With the above explanation, it is clear that draft angle is indeed a must.
