Why You Need Two Way Radios.

Two-way radios were in use long before the smartphones were introduced. However, just because there are cell phones now doesn’t mean they have been rendered obsolete. In job site, mobile phones are often used in communication because they are multi-functional and even convenient. Nonetheless, the two-way radios are still the best option when you are at a job site. When an emergency or disaster occurs, cell service network also goes. Because the two-way radios do not depend on that, they will still be working during that time. During disaster management, a lot of people can be saved if the message to be conveyed reaches many people all at once. When it comes to these radios, you will be able to reach everyone who is in the surrounding. In the case of mobile phones, you will have to call each person individually. Additionally, if you just convey the message to a single person to pass it to other people, he might forget or some things might be distorted in the communication.

The two-way radios are very durable and they do not weight a lot. In the event that they have to be taken to rough environments, you can comfortably use them unlike mobile phones which require you to buy a casing not to mention the fact that they do not get damaged because of falls. In the manufacture of the radios, the specifications are military standard not to forget IP specifications and that is why they can survive even in the harshest circumstances. The battery life is also long with some lasting for up to 24 hours. With a fully charged radio, you can be in the field all day long and you will be able to communicate with everyone who has a radio as well.

These are some of the cost-effective phones you will ever find. There are some mobile phones which cost even one thousand dollars and above and those will drain the firm’s budget if you ought to get them. With two way radios, you will not be paying for calling minutes, service contracts of even monthly fees. In addition, there is no need to buy one radio for every member of your team because one is enough for the entire department.The communication is always clear.

About the company Idboss Fake ID, fake ID production technology, a notice to press.

Idboss started business 10 years ago in 1996, producing laminated fake id’s. The business has expanded as the cards are novelty id cards, rather than illegal fake ID cards or replica ID cards.

Idboss was started as EYIC – the European Youth Identity Card, in 1996. The cards produced by EYIC were laminated paper cards, progressing to transparent laminated cards in 1998. The move to advertising in UK men’s lifestyle titles such as Loaded, FHM, Front, Viz, Bizarre and also women’s lifestyle magazines such as More, 19 Magazine and many more.

Around 1996-1998 the Fake ID business was characterised by companies selling fake ID cards in kit form via mail order advertisements. Idboss recognised the need to introduce advanced technology and the drive to improve began with the introduction of a fully bespoke fake ID card service. Before this, customers had to add their own photo and details via a painstaking method of letraset transfers. Idboss Fake ID did away with all that and introduced PVC Fake ID cards.

Customers simply sent in their details and photo, and Idboss did the rest, scanning in the photographs and creating customised Fake ID for each customer.

Other technical innovations include :

Idboss were the first to sell fake ID online
Idboss were the first to sell transparent fake ID
Idboss were the first to sell holographic fake ID

And most importantly,

Idboss created fake ID cards on plastic card for the first time ever.

In 2000, Idboss was launched as a standalone website, with a range of 20 cards.

technology of fake id card production

At present there are more than 30 companies producing fake ID in the UK, ranging from small bedroom-based operations to reliable, large scale enterprises such as Idboss. A complete directory of these websites is available at fake id uk.

Idboss fake id have the highest level of technical knowledge when it comes to making fake ID cards.

Every year, a team of qualified designers re-vamp every card from scratch, so that the cards do not become over-familiar. Design features such as rainbow printing, interweave design, void pantographs, see-through registers, magnetic character recognition ink, intaglio printing and watermarking all add to the effectiveness of the cards.

All cards are designed by a contract team of experienced anti-counterfeit, brand protection experts, and it is this level of expertise that shines through on every card we sell.

A quick glance at the cards of competitiors to Idboss shows that the level of design standards applied by Idboss is second to none, an advantage that adds to the effectiveness of the fake ids.

advanced card manufacturing

Idbosshave been producing high quality fake id for the last ten years, and it is this experience that has resulted in a highly efficient fake id production system.

Each week day, forms are received at the London office. Forms are scanned, and data is entered into the secure temporary database.

Each form is processed in Photoshop manipulation software, photo and signature are separated into distinct files. These images correspond to each customer serial code, which is unique to their order. Photographs are touched up by Photoshop professionals.

Idboss offer several image treatment options, such as close-cropped photographs, transparent ghosted images, and transparent signatures, that appear to “float” over the artwork of the card, a security feature common to passports and driving licences. Orders are dispatched in a carrier, which is a plain white DL envelope with a return address. If your card is undelivered, it is simply returned with no need for anyone to look inside it.

The carrier is 250gsm cardboard which prevents anyone guessing at the contents of the envelope. There are no indications on the envelope that your letter is from Idboss. Every envelope is sealed with tape to prevent tampering.

Idboss cards have it all, superior card designs, excellent card production principles, but to top it all we have the best range of security features to give our fake id cards that extra advantage. Among our card range you can find the following high value security features Embedded Smart Chips (Siemens SLE4443) Working, encoded magnetic stripes Drape-relief printing Void Pantograph anti-copy features Custom holographic overlays.

Most fake id companies offer holographic overlays, however these are usually generic ones available to anyone off the street.

This has severely decreased the value of using such overlays, so much so that they may sometimes even point a card out as fake. Go with the company who has invested the most time into research and design of their fake id cards, sourcing quality and unique holographics, you won’t be disappointed.

a notice to the press


It is important for members of the press to make the distinction between novelty ID and
fake IDs cards.Idboss offer novelty ID cards, which are made up designs, completely fictional and unrelated to any official identity document in circulation.

A search of the internet for fake id will reveal a great deal of articles about illegal fake id vendors, forgers and even people who supply false and stolen identities, GCSE papers and even Utility Bills.

Although 99% of these sites are scams, to even offer such fraudulent documents is highly irresponsible and a practise which Idboss condemn it in the strongest possible terms.

All cards produced by Idboss are novelties – you could not board a plane, rent a car, cross borders or do anything with them that could be remotely illegal.

We discourage the attempted use of our cards for the purposes of misrepresentation, both here and in the documentation supplied with our delivered fake id products.

Any attempt by journalists to characterise our products as false, illegal documentation of use to criminals or terrorists is disingenuous and misleading at best.

Blown Film Extrusion Introduction

Blown Film Extrusion Introduction
Blown film extrusion is a technology that is the most common method to make plastic films, especially for the packaging industry. The process involves extruding a tube of molten polymer through a die and inflating to several times its initial diameter to form a thin film bubble. This bubble is then collapsed and used as a lay-flat film or can be made into bags. Usually polyethylene is used with this process, and other materials can be used as blends with these polymers. A diagram of a polyethylene chain is shown in Figure 1 to the right.
Background Theory on Polymers

In the cooling step of blown film extrusion, the amorphous, transparent melt crystallizes to form a translucent, hazy, or opaque film. The point where opacity begins in the bubble is known as the frost line. 
Fig 1: Model of polytheylene chain frompolyethylene Wikipedia article.The frost line height is controlled by several parameters: the air flow, film speed, and temperature difference between the film and the surroundings. Properties of the film, such as tensile strength, flexural strength, toughness, and optical properties, drastically change depending on the orientation of the molecules. As the transverse or hoop direction properties increase, the machine or longitudinal direction properties decrease. For instance, if all the molecules were aligned in the machine direction, it would be easy to tear the film in that direction, and very difficult in the transverse direction.

The Film Blowing machine Process

Fig 2: Schematic of set-up from User:J.Chiang.

Typically, blown film extrusion is carried out vertically upwards, however horizontal and downward extrusion processes are now becoming more common. Figure 2 shows a schematic of the set-up for blown film extrusion. This procedure consists of four main steps: The polymer material starts in a pellet form, which are successively compacted and melted to form a continuous, viscous liquid. This molten plastic is then forced, or extruded, through an annular die. Air is injected through a hole in the center of the die, and the pressure causes the extruded melt to expand into a bubble. The air entering the bubble replaces air leaving it, so that even and constant pressure is maintained to ensure uniform thickness of the film. The bubble is pulled continually upwards from the die and a cooling ring blows air onto the film. The film can also be cooled from the inside using internal bubble cooling. This reduces the temperature inside the bubble, while maintaining the bubble diameter. After solidification at the frost line, the film moves into a set of nip rollers which collapse the bubble and flatten it into two flat film layers. The puller rolls pull the film onto windup rollers. The film passes through idler rolls during this process to ensure that there is uniform tension in the film. Between the nip rollers and the windup rollers, the film may pass through a treatment centre, depending on the application. During this stage, the film may be slit to form one or two films, or surface treated. Advantages Blown film generally has a better balance of mechanical properties than cast or extruded films because it is drawn in both the transverse and machine directions. Mechanical properties of the thin film include tensile and flexural strength, and toughness. The nearly uniform properties in both directions allow for maximum toughness in the film.
Blown film extrusion can be used to make one large film, two smaller ones, or tubes that can be made into bags. Also, one die can make many different widths and sizes without significant trimming. This high level of flexibility in the process leads to less scrap material and higher productivity. Blown films also require lower melting temperatures than cast extrusion. Measured at the die opening, the temperature of cast film is about 220 C, where as the temperature of blown film is about 135 C. Furthermore, the cost of the equipment is approximately 50% of a cast line.

Blown Film Extrusion Disadvantages Blown film has a less effective cooling process than flat film. Flat film cooling is done by means of chill rolls or water, which have significantly higher specific heat capacities than the air that is used in the blown film cooling process. The higher specific heat capacity allows the substance to absorb more heat with less change in the substance temperature. Compared to cast film, blown film has a more complicated and less accurate method to control film thickness; cast film has a thickness variation of 1 to 2% versus the 3 to 4% for blown film. The resins used for casting typically have a lower melt flow index, which is the amount of polymer that can be forced through a standard die in 10 minutes according to a standard procedure. The melt flow index for cast film is about 5.0 g/10 min where as for blown film it is about 1.0 g/10 min. Consequently, the production rates for cast film are higher: cast film lines can reach production rates of up to 300m/min where as blown film lines are usually less than half this value. And finally, cast film has better optical properties, including transparency, haze, and gloss.

Common Problems Air entrapment between film layers and rollers – this may cause film scratching or wrinkling, or processing problems when winding up the film due to reduced friction. Possible solutions to this is using a vacuum to remove entrapped air or by using winding rolls with a diamond shaped groove in the rubber cover to increase surface area and decrease amount of entrapped air in the film. Large output fluctuations from the die – this causes thickness variations, and can be prevented by keeping the extruder clean and by using more consistently shaped pellets in the extruder. Melt fractures – these appear as roughness or wavy lines on the film surface, and can be eliminated by lowering the viscosity of the polymer melt. This can be done by increasing the melting temperature or by adding an internal lubricant to the material composition. Thickness variations in the film – this can be avoided by centering the die in the extrusion line before every run, adjusting the air speed of the cooling system, or by using heated die lips. Die lines on the surface of the film – this defect reduces the aesthetic appeal of the film, reduces optical properties, and weakens mechanical properties such as tear strength. This can usually be avoided by routinely cleaning the inner surfaces of the die and by refinishing scratched or roughened flow surfaces. Gels – these defects are small, hard globules encapsulated in the film or stuck on the film surface and reduce the aesthetic appeal of the film and cause stress concentration points which may result in premature failure. These are caused by overheating to the point of polymer degradation in the die, and can therefore be avoided by cleaning the inner surfaces of the die on a regular basis. Optimization of the Process Coextrusion One way to improve the line efficiency of blown film extrusion is to implement coextrusion. This is the process of extruding two or more materials simultaneously through a single die. The orifices in the die are arranged such that the layers merge together before cooling. This process saves time because it extrudes two or more layers at the same time, and it provides a method with fewer steps to produce multilayer films. The production rate for a coextruded multilayer film of three layers is about 65m/min, and the production rate for a single layer of blown film is about 130m/min. Thus, in order to produce 10 000m of a three layer multilayer film, it would take almost 4 hours using a single layer blown film process, and only 2 and a half hours using the coextrusion process. Furthermore, the film produced from the single layer process would require an extra step to glue the layers together using some sort of adhesive. Coextrusion is the least expensive means of producing layered films and the coextrusion system is capable of quick changeovers to minimize production line down time.

Minimizing the Melt Temperature
The efficiency of blown film extrusion can be improved by minimizing the temperature of the polymer melt. Reduction of the melt temperature causes the melt to require less heating in the extruder. Normal extrusion conditions have a melting temperature at about 190 C despite the fact that the temperature of the melt only needs to be about 135 C. However, it is not always practical to decrease the melting temperature by that much. By decreasing the melt temperature 2 to 20 C, the motor load can be decreased by about 1 to 10%. Furthermore, reduction of the melt temperature causes less need for cooling, so there is a reduced use of the cooling system. Moreover, removing heat from the bubble is usually the rate-limiting factor in this extrusion process, so by having less heat in the polymer to remove, the rate of the process can be increased, thus yielding higher productivity. A way to maintain the melt temperature at a minimum is to choose an extruder that is matched to the specific processing conditions, such as the material of the melt, pressure, and throughput.

Heated Extrusion Die Lips
Typically, solutions to melt fractures involve decreasing the output or increasing the melt temperature to decrease the shear stress in the extruder. Both of these methods are not ideal because they both reduce the efficiency of the blown film line. Heated extrusion die lips can solve this problem. This targeted heating method allows for film extruders to be run at higher production rates with narrower die gaps while eliminating melt fractures. Direct heat is applied to the surface of the polymer melt as it exits the die so that viscosity is reduced. Therefore, melt fractures, which are caused when trying to extrude too much of the polymer at one time, will no longer act as a limiting factor to increasing the production rate. Furthermore, heated die lips use less energy than increasing the melting temperature because only the surface of the melt is heated and not the bulk of the liquid. Another benefit of using heated die lips is that thickness variations can be controlled by adding heat to certain areas along the die circumference to make the film at that position thinner. This would ensure that no excess material is used.
Determine how much energy each of these processes can save per given volume of material.
