Understanding Optical Fiber

is a cable Technology that uses yarn (fiber) glass or plastic) transmit data. Fiber optic cables consist of a bunch of glass yarns, each of which is capable of transmitting modulation messages to light waves. Glass fibers typically have a diameter of about 120 micrometers with those used to transmit light signals from one place to another up to 50km distance without using a repeater. Wave signals may be coding of voice communications or computer data.

Fiber optic communication depends on the principle of light on the glass medium It can carry more information and distances than electrical signals carried by copper or coaxial media. The purity of glass fibers coupled with advanced electronic systems enables fibers to primarily transmit digital light signals beyond 100 km without a reinforcement device. Fiber optics is an ideal transmission medium with minimal transmission loss, low noise and high bandwidth potential.

The Working Principle of Optical Fiber 

Fiber optic structure consists of several arrangement that is Cladding, Core, and Buffer Coating. Core or core is a thin glass fiber into a light-running medium, so light delivery can be done. Cladding is the outer layer that protects the nucleus and reflects back the light that radiates out back into the core. While Buffer Coating is a plastic sheath that aims to protect the fiber from damage resulting from cable curves and external disturbances such as moisture.

The working principle of Fiber

optics depends on the principle of the number of internal reflections. Reflection of light or refraction based on the angle that attacks the surface. This principle centers on the workings of optical fibers Limiting the angle at which light waves are sent makes it possible to controlefficiently until the test. Light waves are covered with a core of optical fibers, in the same way that the radio signal frequency is covered with a coaxial cable. The light wave is directed to the fiber end by reflected in the core. Fiber optic cables are usually applied to telecommunication network infrastructure such as telephone networks and computer networks.

Types of Fiber Optic Cables There are two types of Fiber Optic Cables:

Multimode optical fiber cables are the type used for commercial purposes. Larger cores of single-mode fiber allow hundreds of light modes scattered over the fibers simultaneously. In addition multimode diameter has a larger core fiber (0.0025 inch diameter or 62.5 micron) and serves to transmit infrared laser light (wavelength 850-1300 nm) 

Single mode optical fiber cable has a smaller core (diameter 0.00035 inch or 9 micron) and serves to transmit infrared laser light (wavelength 1300-1550 nm) which allows only one mode to diffuse light through the core at a time. Single mode fibers are developed to maintain the integrity of spatial data and the spectra of each optical signal over a longer distance

Basic Steps Of Injection

advertisement


Injection molding is a popular manufacturing method for many reasons. It has proven especially valuable to those in the consumer product development sector, since plastics are a primary component of many consumer products, and injection molding is one of the best ways to manufacture plastics. Let’s take a quick look at the three major phases of the injection molding process, and then discuss the advantages and disadvantages of the process.

Injection Molding Process, Basic Step 1: Product Design 

Design is one of the most important facets of the production process because it’s the earliest opportunity to prevent expensive mistakes later on. (Of course, determining whether you have a good idea in the first place is also important, but more on that here.) There are many objectives to design for: function, aesthetics, manufacturability, assembly, etc. The right design is one that accomplishes the required objectives to a satisfactory level, but it may take a lot of creativity to get there. Product design is most often accomplished with computer aided design (CAD) software, like SolidWorks. (Click here for nine pro tips on how to best use SolidWorks in design and engineering.) Proficiency with CAD software is vital because it allows for quicker iterations and more accurate prototyping if necessary.M

Design and engineering for injection molding 

Some specific ways to avoid costly mistakes during the product design process are to plan for uniform wall thickness whenever possible, and to gradually transition from one thickness to another when changes in thickness are not avoidable. It is also important to avoid building stress into the design, such as corners that are 90 degrees or less. (Read more about Injection Molding Defects here.) 

A skilled team of design engineers will be able to brainstorm, design, and improve upon a variety of solutions to meet the particular complexities of a specific project. The design team at Creative Mechanisms has combined decades of experience creating elegant solutions to complex problems. Meet some of our team here, here, or here, or visit our Customer Testimonials page to see what previous and current clients have to say about our product design capabilities. We think you’ll be impressed.

Injection Molding Process, Basic Step 2: Mold Design 

After a looks-like, feels-like design has been tested and slated for further production, the mold (or die) needs to be designed for injection mold manufacturing. Molds are commonly made from these types of metals: 

Hardened steel: Typically the most expensive material to use for a mold, and generally the longest-lasting (which can drive down price per unit). This makes hardened steel a good material choice for products where multiple hundreds of thousands are to be produced. Prehardened steel: Does not last as many cycles as hardened steel, and is less expensive to create. Aluminum: Most commonly used for single cavity "Prototype Tooling" when a relatively low number of parts are needed for testing. Once the injection molded parts from this tool are tested and approved, then a multi cavity steel production tool is produced. It is possible to get many thousands of parts from an aluminum tool but typically it is used for lower quantities. 

Beryllium-Copper alloy: Typically used in areas of the mold that need fast heat removal or where shear heat is concentrated. 

Creating Prototypes In Injection Molding MaterialJust as with overall product design, mold design is another opportunity to prevent defects during the injection molding process. We have previously written blogs on the Top 10 Injection Molding Defects and Avoiding Mistakes in Injection Molding, but here are some examples of how poor mold design can be a costly mistake: 

Not designing the proper draft: This refers to the angle at which the finished product is ejected from the mold. An insufficient draft can lead to ejection problems, costing significant time and money. Improperly placed or sized gates: Gates are the openings in a mold through which thermoset or thermoplastic material is injected. Each will leave a vestige (scar), which can create aesthetic or functional problems if not properly placed. 

The number of parts (cycles) required, as well as the material they will be made of will help drive decision-making as to how and with what materials to create the mold.

Injection Molding Process, Basic Step 3: The Manufacturing Process 

When a product has been properly designed, approved, and die cast, it’s time to start the actual manufacturing! Here are the basics of the injection molding process… 

Thermoset or thermoplastic material in granular form is fed through a hopper into a heating barrel. (Learn more about the differences between plastics in our PLASTICS course.) The plastic is heated to a predetermined temperature and driven by a large screw through the gate(s) and into the mold. Once the mold is filled, the screw will remain in place to apply appropriate pressure for the duration of a predetermined cooling time. Upon reaching this point, the screw is withdrawn, the mold opened, and the part ejected. Gates will either shear off automatically or be manually removed. This cycle will repeat over and over, and can be used to create hundreds of thousands of parts in a relatively short amount of time.

Life Insurance

advertisement
Life insurance is designed to provide financial security for relatives of the deceased, most commonly spouses and children. If you support someone with your income or your time and they won’t be able to provide that support for themselves without you, then you need life insurance.

Life Insurance Introduction: Who Needs It? While it is possible to purchase life insurance for a child, it is generally unnecessary. Life insurance is supposed to make sure that anyone who depends on the insured for income or day-to-day support will be financially provided for when the insured dies. Children are rarely responsible for this level of support. Companies sell life insurance for children under the premise that parents will need it to pay for burial expenses if their child dies prematurely, that it’s a good way to save for a child’s future and that it’s a good idea to insure your child now in case they become uninsurable later due to a serious childhood illness. 

Many people don’t realize how important life insurance is; they are more concerned with saving and investing for retirement than they are with making sure they have enough life insurance coverage. (Source: http://www.foxbusiness.com/features/2017/03/16/americans-shun-life-insur...) While a retirement nest egg will certainly help your family, it will likely provide nowhere near the amount of financial support that an insurance policy could. Plus, early retirement account withdrawals may be subject to penalties and taxes, whereas life insurance proceeds are tax free.

But families can set aside money in savings to pay for burial expenses or plan to use their emergency fund to cover such a worst-case scenario, and there are better ways to save for a child’s future, such as custodial accounts and 529 plans. And the odds of becoming completely uninsurable before the age of 18 are slim. (For more on life insurance for kids, see The Pros of an Endowment Life Insurance Policy.)

Young adults often do not need life insurance because no one depends on them, either. However, the argument for purchasing life insurance as a young adult becomes more compelling if that individual plans to get married and/or have children. The younger and healthier you are when you buy life insurance, the less expensive it is. (For related reading, see How Age Affects Life Insurance.)

Further, some young adults may find that it makes sense to buy life insurance so there will be money to pay off their private student loans if they have a cosigner such as a parent who would struggle to pay the bill if it became their responsibility. Private student lenders do not necessarily discharge loans in these situations, though federal student lenders do; the only financial liability for the loan after death is that the deceased’s estate will be responsible for taxes on the amount of debt that was forgiven.

Cloud computing

Cloud computing is changing the way IT is delivered to businesses and how businesses can now leverage the technologies to be very nimble and agile, yet large. Cloud is a technology that maintains data and applications by making use of the internet and central remote servers. Cloud computing enables users to run their necessary applications without actually installing the software or hardware. The consumers can access their necessary files at any remote computer having internet access. This technology is handy as it facilitates efficient computing by a central storage, memory, process and bandwidth.

Cloud computing can be broken down into three components:

• "Application"

• "Storage"

• "Connectivity."

Each segment serves a different purpose and offers different products for businesses and individuals around the world.

Cloud computing has two primary deployment models. They are:

Community cloud - In this concept of Cloud, several organizations from a specific community with common concerns share infrastructure between themselves. They could be managed either internally or by a third-party and the hosting could be internal or external. The costs have are distributed among fewer users.

Public cloud - This concept of Cloud is established when several organizations having similar requirements and seeking to share infrastructure are concerned. This definitely is more viable in terms of monetary benefit, as the resources (storage, workstations) utilized and shared in the community are used by a huge number of consumers.

The advantages of Cloud Computing offering in IT services include the following:

1. Transformation into on demand IT-as-a-service

2. Greater business agility, on-demand provisioning

3. Self-provisioning & deployment of applications

4. Significant savings in total cost of operations through right sizing and operational efficiency

5. Dynamic capacity on demand to reduce time to market

6. Strategically align the business on long-term opportunities while optimizing on operations

The transition to Cloud however, is accompanied by a number of data security issues that need to be looked into. Most organizations use relational databases to store the most sensitive data, hence the need of data security while moving to Cloud becomes all the more important and imperative. So, as the consumers work on migrating applications to Cloud, they need to be careful about three main attributes involving data security.

User access privileges: Any sensitive data that is processed outside the enterprise is prone to an elemental risk. As the services are outsourced, they kind of discount the physical, logical and personnel regulations which the IT departments could exercise over the in-house programs.

Server Elasticity: One of the key perks of Cloud computing is flexibility. So, keeping apart the fact about users having knowledge of the exact location of where their data is hosted, the servers hosting the concerned data can be provisioned and de-provisioned regularly to mirror the current requirement capacity. This evolving topology can be a challenge for the technologies banked on today and could be very hard for the management to constantly update configurations fitting to every such change.

Regulatory Compliance: Data integrity and data security are but the ultimate responsibilities of the organizations even if it is held by a service provider. The whole system of educating the auditors, demonstrating that their data is safe and secure even when there is no physical control over systems, is challenging. They need to provide them with the quintessential visibility into all activity.

Controlling access and monitoring of cloud administrators is a cutting point to make sure that sensitive data is secure. While the users may want to maintain background checks of their own privileged users and may also enforce significant physical monitoring, even if this be done by their cloud provider - it is a process which is not their own. Therefore that would mean compromising some element of power or control. These individuals may have almost unlimited access to the infrastructure, something they require in order to maintain and check the performance and availability of the cloud resources for all customers.
