What is Material Engineering?

I believe that most of the people out there have not heard of this field, materials engineering. Surely you've heard of the traditional fields of engineering such as mechanical, electric, electronic, civil and chemical. So what exactly is this type of engineering all about?

It is not a new field in engineering at all. Historically, the study on materials is not as extensive as it is now. Not to be confused with materials science however, both fields strive to discover more knowledge of the existing materials around us.

Materials science mostly focuses on the basic study of materials, which includes basic mathematical formulae and also the foundation physics of materials. Materials engineering on the other hand concentrates on the development of new materials for industrial and user applications.

Take this basic example to illustrate the focus of this type of engineering. We've seen the rise of LCD TVs in the recent years. In the next few years, LED TVs would most probably dominate the market for slim TVs. Previously, the colours which could be emitted by an LED were limited to red and yellow.

The development of newer materials to produce different colours completes the red, green and blue spectrum. Before this, blue LEDs were almost non-existent. With these new materials for LEDs, electric and electronics engineers are then able to put everything together to produce the LCD TV we now have.

The field of materials engineering is very wide. In order to achieve further technological breakthroughs, material engineers are now looking towards customizing materials from the inside out, in nano scale.

Material Handling Systems - Different Types and Applications

Material handling systems are created in order to provide quicker automation services for several enterprises. They are essential parts for the material handling process. The systems will bring much comfort and ease on the part of the client especially those concerning how to automate company facilities. At times, if the client is lucky enough, the materials handling team will take care of the installation of the desired machinery for the business.

The system actually involves a set of services that clients will favor for their existing businesses. It involves system design and integration, factory automation, warehousing solutions and factory upgrade. Automatic guided vehicles, automated storage and retrieval systems and order fulfillment systems are common types of material handling systems. Below is an explanation of each of these types and the applications where it is utilized.

Automates storage and retrieval systems

This system minimizes labor and utilization of floor space while vertical space is maximized. This is considered one of the contributors to the success of businesses worldwide. It is very efficient in reducing human intervention as it improves the company's performance and accuracy.

Applications for this type of material handling system are varied. The manufacturing process makes use of modern applications to increase efficiency in production, work-in-process storage and just-in-time delivery services. For archival and security applications, the system serves well by providing vaults where valued material may be sourced out for future consumption. In the world of electronics, it is capable of handling operation without the need for manual intervention. Other areas where this system is used are in production of food and beverages and conventional warehousing.

Automated guided vehicles

Automated guided vehicles are types of material handling systems growing popularly in several industries. It includes counterbalance and unit load vehicles as well as specialty style vehicles. Robotic transporters are employed to do the entire job and are based on Windows applications. The most common applications for AGV are aerospace, automotive, mail processing, manufacturing, plastics and warehousing industries.
Other types of systems for the material handling process

Aside from the above-mentioned types of material handling systems, there are other kinds included in the list. Order fulfillment systems are used in order to handle concerns of clients when it comes to the ordering process. This may either be operator-assisted or fully automated. Another is the sorting system which is a crucial portion of the distribution system. This is essential in order to work with timetables and produce high quality goods for industries relying upon these systems. Conveyors, logistics software, and palletizing or depalletizing are also examples of systems for the material handling process.
