About Die Casting Process

Die casting is a widespread non-expendable technique in which metal are forced into the mold cavity under high pressure. Die casting mold that are known as dies can be used repeatedly to produce castings in a variety of sizes, shapes and wall thickness. The mold cavities are designed with intricate designs that enables in producing complex shapes with accuracy, surface finish and attractiveness..

History of Die Casting

In the early days of die casting only low-pressure injection method was used, but today high-pressure casting techniques like squeeze casting and semi-solid die casting methods are use to cast more than 4500 pounds per square inch. Initially, only tin and lead were die caste, but now magnesium, copper and other alloys are also to cast using this highly popular process.

Die Casting Process

In this process molten metal or other materials are forced, under high pressure into the cavities of the steel mold. Dies are two part molds that are made of alloy tool steel - The fixer die half and the ejector die half. The die or mold is fabricated with the impression of the component that is to cast. There are four types of dies:

Single cavity to produce one component
Multiple cavity to produce a number of identical parts
Unit die to produce different parts at one time
Combinations die to produce several different parts for an assembly

The molten metal is injected into the die under high pressure and high speed, which helps in producing a casting that is smooth and precise as the original mold. The pressure is maintained on the mold until the hot metal solidifies. When the metal is hardened, the die is opened to reMove the casting.

There are several variations on the basic process that can be used to produce castings for specific applications. These include:

Squeeze casting - A method by which molten alloy is cast without turbulence and gas entrapment at high pressure to yield high quality, dense, heat treatable components.

Semi-solid molding - A procedure where semi-solid metal billets are cast to provide dense, heat treatable castings with low porosity.

Alloys used

Aluminum, copper, lead, zinc and tin based alloys are predominantly used in die-casting.

Automation

In modern day, sophisticated die casting machines are used that ensures consistent quality control. Every machined die-casting differs in the method in which molten meal is poured into the die. Automations are used to lubricate dies, pour the metal into the chamber, etc. Two processes called the hot chamber and the cold chamber methods are used for die casting.

Applications

Die casting is most suitable for casting medium sized parts with complex details. Die-casting is the largest casting technique that is used to manufacture consumer, commercial and industrial products like automobiles, Toys, parts of sink faucet, connector housing, gears, etc. Most die castings are done from non-ferrous metals like aluminum, magnesium, etc.

Advantages

Economical process that can be used for a wide range of complex application
Parts have longer service life, dimensional accuracy and close tolerance
Post machining can be totally eliminated
A process that can be fully automated
Mold can be use repeatedly.

Disadvantages

Casting weight must be between 30 grams.

Generalized Audit Software (GAS)

GAS consists of a series of computer program routines that can read computer files, select desired information, perform repetitive calculations, and print reports in an Auditor-specified format. Generalized Audit Software enables Auditors to have direct access to computerized records and to deal effectively with large quantities of data. Since GAS can quickly scan, test, and summarize all the data in a computer file, many procedures that ordinarily would be performed on a sample basis can be extended to the entire population. In addition, the use of GAS typically leads to a better understanding of automated systems and computer-based operations. It can make auditing more interesting and challenging and is an excellent way of introducing Auditors to evidence collection process and electronic data file integrity checking within an IT Environment.

Generalized Audit Software can accomplish the following audit tasks:

1. Examine records for quality, completeness, consistency, and correctness (review bank demand deposit files for unusually large deposits and withdrawals)

2. Verify calculations and make computations (re-compute interest, Bank COT, etc. and verify payroll Net pay, Deductions, etc.)

3. Compare data on separate files (compare current and prior-period inventory files for obsolete and slow-moving items)

4. Select and print audit samples (accounts receivable confirmations, customer refunds over a certain amount).

5. Summarize and re-sequence data (re-sequence inventory items by location to facilitate physical observations).

6. Compare data obtained through other audit procedures with company records (compare creditor statements with accounts payable files).

Some advanced GAS can include a wide variety of audit functions. They enable even novice-Auditors to perform professional jobs. Apart from the wide range of audit functions and the ease of use, the advanced GAS are now able to access, analyze and report on a range of different files saved in heterogeneous hardware and software platforms which are distributed through either an enterprise Intranet facilities or other means, including the global computer networks. Two common names in these features are ACL and IDEA.

GAS provides the distinct advantage over conventional programming languages of being relatively easy to learn and use. Most GAS systems require only about one week of training, and proficiency may be attained after several weeks of use. Furthermore, GAS specification coding, typically requires a fraction of the coding entries needed for conventional programming languages. This permits faster coding and reduces the likelihood of errors.

The Advantages of eLearning

The Advantages of eLearning

In the 21st century, people have to learn more than ever before. Especially for global organizations, live classroom-based training is becoming too costly and cumbersome. Even if employees had the time to attend all the courses and seminars and to read all the books and reports they should to remain up-to-date in their area of work, the cost of such learning would be prohibitive. The need to transform how organizations learn points to a more modern, efficient, and flexible alternative: eLearning. The mission of corporate eLearning is to Supply the workforce with an up-to-date and cost-effective program that yields motivated, skilled, and loyal knowledge workers.

Anywhere, anytime, anyone.

The Internet can offer the logical solution for a company's education and training objectives. Approximately 80% of the professional workforce already uses computers on the job. Technical obstacles, such as access, standards, infrastructure, and bandwidth, will not be an issue in a few years. The growth of the World Wide Web, high-capacity corporate networks, and high-speed desktop computers will make learning available to people 24 hours a day, seven days a week around the globe. This will enable businesses to distribute training and critical information to multiple locations easily and conveniently. Employees can then access training when it is convenient for them, at home or in the office.

Substantial cost savings due to elimination of travel expenses.

When delivered through technology based solutions, training is less expensive per end user due to scalable distribution and the elimination of high salaries for trainers and consultants. The biggest benefit of eLearning, however, is that it eliminates the expense and inconvenience of getting the instructor and students in the same place. According to Training Magazine, corporations save between 50-70% when replacing instructor-led training with electronic content delivery. Opting for eLearning also means that courses can be pared into shorter sessions and spread out over several days or weeks so that the business would not lose an employee for entire days at a time. Workers can also improve productivity and use their own time more efficiently, as they no longer need to travel or fight rush-hour traffic to get to a class.

Just-in-time access to timely information.

Web-based products allow instructors to update lessons and materials across the entire network instantly. This keeps content fresh and consistent and gives students immediate access to the most current data. Information can be retrieved just before it is required, rather than being learned once in a classroom and subsequently forgotten. Training Magazine reported that technology-based training has proven to have a 50-60% better consistency of learning than traditional classroom learning (c-learning).

Higher retention of content through personalized learning.

Technology-based solutions allow more room for individual differences in learning styles. They also provide a high level of simulation that can be tailored to the learner's level of proficiency. With 24 x 7 access, people can learn at their own pace and review course material as often as needed. Since they can customize the learning material to their own needs, students have more control over their learning process and can better understand the material, leading to a 60% faster learning curve, compared to instructor-led training. The delivery of content in smaller units, called "chunks," contributes further to a more lasting learning effect. Whereas the average content retention rate for an instructor-led class is only 58%, the more intensive eLearning experience enhances the retention rate by 25 - 60%.1 Higher retention of the material puts a higher value on every dollar spent on training.

Improved collaboration and interactivity among students.

In times when small instructor-led classes tend to be the exception, electronic learning solutions can offer more collaboration and interaction with experts and peers as well as a higher success rate than the live alternative. Teaching and communication techniques which create an interactive online environment include case studies, story-telling, demonstrations, role-playing, simulations, streamed videos, online references, personalized coaching and mentoring, discussion groups, project teams, chat rooms, e-mail, bulletin boards, tips, tutorials, FAQs, and wizards.

Distance education can be more stimulating and encourage more critical reasoning than a traditional large instructor-led class because it allows the kind of interaction that takes place most fully in small group settings. Studies have shown that students who take online courses are typically drawn into the subject matter of the class more deeply than in a traditional course because of the discussions they get involved in.2 This engagement is further facilitated by the fact that instructors do not monopolize attention in an online environment. Another study found that online students had more peer contact with others in the class, enjoyed it more, spent more time on class work, understood the material better, and performed, on average, 20% better than students who were taught in the traditional classroom.

Online training is less intimidating than instructor-led courses.

Students taking an online course enter a risk-free environment in which they can try new things and make mistakes without exposing themselves. This characteristic is particularly valuable when trying to learn soft skills, such as leadership and decision making. A good learning program shows the consequences of students' actions and here/why they went wrong. After a failure, students can go back and try again. This type of learning experience eliminates the embarrassment of failure in front of a group.

With all of these advantages of taking classes online, it is hard to imagine why anyone would opt to sit in a lecture to learn new information. There are online classes available free on a multitude of topics, just start surfing, find one to your liking, and start learning!
