Police Badges, Fire Fighter Badges, and Security Professional Badges

Serving the needs of professional police and fire agencies all over world, JIAN Badge continues to provide the highest quality police and fire badges available. Our unique fire and police badges designs, durability and outstanding appearance are unequaled in the industry. The widest range of services are provided for creating police and fire badges that cannot be ignored.
Each fire and police badges speaks for itself as it stands out from all the others and never goes unnoticed. All of our resources at JIAN Badge are aimed at creating the finest police and fire badges to be found anywhere regardless of price. Each police and fire badge must look and feel distinctly refined as more than a police and fire badge. police and fire badges are emblems of professionalism, authority, distinction and quality that represents the officer wearing the badge.
JIAN badge begins with solid design excellence drawing on the skills of designers, photographers, artists, engravers, and die makers. The distinctive excellence of every police and fire badge cannot just stand apart from the others but must 'stand alone' as the emblem of excellence and authority for the Police and Fire Department it represents.
Once the design is completed, we select the finest and most appropriate materials available to manufacture the newly designed police and fire badge. At JIAN Badge we make badges from solid metal materials of the finest quality available. Every stage of constructing the badge is closely monitored to insure quality and durability surpassing all others. The 'finished' police and fire badge is always the welcome result of a well laid out plan. Police and Fire Agencies no longer accept assembly line, 'fill in your name here' badges from Police and Fire supply stores. Thin hollow police and fire badges punched out of inferior materials and thinly plated to look like something they're not, is no longer acceptable to Police and Fire professionals. Punched letters filled with paint can't compare to fine jeweler's cloisonne we call 'hard fired enamel'.
As we dignify the badge, we dignify the Department that wears it. Once you see our quality, you'll see why we believe that badges can 'speak for themselves'. Words alone don't always express what we desire. It's better expressed by a police and fire badge of superior appearance that can be worn with pride. A police and fire badge truly distinct and set apart from all others exemplifying the true appearance of the Police and Fire professional will speak for itself.

Custom Metal Pins

Soft Enamel Pins(Custom Metal Pins)
Soft Enamel Pins are what we call a standard enamel pin. These are the most common of the enamel pins and are a more affordable option from Hard Enamel Pins. The pins are die struck and then polished, once polished we would fill in the open spaces with whatever color enamel your artwork requires. The metal outlines remain raised so you can feel the texture across your design. A stamped logo or small design on the back of your pin is an optional feature we offer.
Hard Enamel Pins(Custom Metal Pins)
Hard Enamel Pins are the highest quality pins available in today's market. They have great durability and a premium choice for corporations or small business's alike. Hard Enamel Pins are die struck then filled with enamel color to complete the design. Each color is separated by thin lines that define the design. Once the enamel is filled, they are heated to a high temperature and then polished creating a premium pin with smooth finish. If you want the metal lines that separate each color to remain raised, we would suggest a soft enamel pin. Hard Enamel pins have a premium finish but are also slightly more expensive than the standard Soft Enamel Pin. A stamped logo or small design on the back of your pin is an optional feature we offer.

Introduction of automatic recirculation valve

Automatic Recirculation Valves protect centrifugal pumps from damage that may occur during low-flow operations. Minimum flow protection is accomplished with an automatic, modulating bypass that assures smooth pump operation between the minimum and maximum flow point on the pump curve.
No external power source is required. These valves are self-contained and simplify the system design and installation. Sizes range from 1 inch to 24 inches, including ANSI Class 150 through 2500 lb. Valve internals are stainless steel with housing in carbon steel, stainless steel, or special machinable alloys.
The primary function of AUTOMATIC RECIRCULATION VALVES is to assure the Minimum continuous Flow (Qmin) required by the centrifugal pump during all operating conditions. Centrifugal pumps can be damaged due to cavitation and over-heating during ‘low flow’ and ‘no flow’ operations.
OPERATION OF AUTOMATIC RECIRCULATION VALVES
The valve combines the functions of:
Main Flow check valve disk that is flow sensitive and modulates with the process flow over the full pressure range. The Main Flow check valve disk is designed as a Non-Return Check Valve to prevent reverse flow from process.
Bypass valve head that controls the designed bypass flow (Qmin). The Bypass valve head modulates with the process demand flow to assure Qmin and to ‘shut off’ when the process demand is in excess of the required Qmin.
Throttle that internally provides pressure reduction for the bypass flow.
When the Main Flow check valve disk is on the valve seat, the Bypass valve head is 100% open.
In this position there is no flow to process and the open Bypass provides the Minimum continuous Flow (Qmin) to protect the pump from ‘low flow’ and ‘no flow’ damages.
As the process control valve begins to open – the Main Flow check valve disk will move and begin to allow flow to the process. The Bypass valve head will begin to close. In this modulating function (partial process flow and partial bypass flow) the Minimum continuous Flow is assured.
As the Main Flow check valve disk continues to open due to the increase in process demand the Bypass valve head will ‘shut off’ when the process demand is in excess of the Minimum continuous Flow. This allows all the pump energy to flow to the process demand.

5 Common Mistakes in Laser Engraving and How to Avoid Them

Whether you are an experienced engineer or a novice maker, learning the proper uses of design equipment to avoid pitfalls and mistakes takes time and experience.
From time to time, issues come up that leave designers wondering what they did wrong or how they could do something better. This is true in any field and laser engraving is no different.
Knowing how to avoid these mistakes so they don’t come up again is half the battle. Mistake 1: Engraving Fabric but the Laser Burns through the Material
The first step in avoiding burning fabric with a laser Cnc engraving machine is to understand what fabric can withstand the process and at what temperatures. Heartier fabrics such as denim, canvas and leather can withstand higher power settings during engraving. But when it comes to delicate fabrics, it is important to start on a high speed setting and a low power setting—maybe 5 percent to 10 percent. Then if the fabric can withstand it, increase the power from there until you get the results you are looking for.
When it comes to direct-to-garment engraving, it is helpful to lower the dots per inch (DPI) at which you engrave. The higher the DPI, the more material will be removed. Engraving at a lower DPI helps ensure the laser just slightly vaporizes the top layer and doesn’t burn entirely through the fabric. Most fabric engravings do fine at 150 to 300 DPI.
Mistake 2: Acrylic Doesn’t Produce a Frosty White Engraving
More than likely, this is caused by using the wrong acrylic in the application. Two types of acrylics are typically used in laser engraving and both are suitable for different applications.
Cast acrylic sheets and objects are made from a liquid acrylic that is poured into molds that then can be set into various shapes and sizes. This type of acrylic is ideal for engraving because it turns a frosty white color when engraved, making it suitable for awards and plaques. It can be cut with a laser, but it won’t give projects flame-polished edges.
The other type used in laser engraving is called extruded acrylic, which is formed into sheets by a machine. Extruded acrylic is generally less expensive than cast acrylic because it is formed through a higher-volume manufacturing technique. However, it does react very differently with the laser-engraving machine. This type of acrylic cuts cleanly and smoothly and produces a flame-polished edge; however, when engraved, it doesn’t produce that frosted look, but rather a clear engraving. So make sure you are using cast acrylic if you want a frosted white finish.
Mistake 3: Inconsistent Glass Engraving
Oftentimes, when a laser strikes glass it will fracture the surface but not engrave deeply or remove the material needed to engrave fully. The fractured glass surface will produce a frosted appearance, but can be rough and chipped depending on the type of glass that is being engraved. While the frosted look is desired, no one wants a rough surface or chipping.
In order to produce a smooth frosted finish, try incorporating one or several of the tips below:
• Use a lower resolution, about 300 DPI, which will produce a better result on glass as you separate the dots you are engraving.
• Change the black in your graphic to 80 percent black to improve the engraving quality.
• Sometimes, applying a thin, wet sheet of newspaper or a paper towel to the engraving area will help with heat dissipation and improve the engraving process. Just make sure there are no wrinkles in the paper after it is applied.
• Another way to dissipate heat is to apply a thin coat of liquid dish soap – either with your finger or a paper towel to the area you’re engraving.
• Finally, if there are shards of glass after engraving, polish the area with a non-scratch scour pad.
Mistake 4: Wood Engraving Produces Different Results on the Same Setting
Wood is one of the most laser-friendly materials available not only because it can be cut very easily, but also because it engraves very well.
However, different woods have different reactions when they are laser-engraved and produce different characteristics. Lighter woods, like cherry or maple, produce a nice contrast where the laser burns away the wood, while denser woods require more laser power to cut or engrave.
When laser engraving wood, grain density can change dramatically depending on the type. Cherry, alder, walnut and maple have fairly little veins of grain in them, while oak has medium to large veins. For example, if a large box was engraved into a piece of cherry and a piece of oak, the box engraved into the cherry would have a very uniform appearance, the area engraved or the background would be smooth with little variation in height. The oak on the other hand would vary greatly in height and have a very non-uniformed appearance.
Here are some tips when engraving with wood:
• Maple and alder are some of the the most popular woods for engraving, providing a rich contrast.
• Bare wood engraving produces smoke and debris during the process and can become embedded into the grain of the wood. To reduce this effect, always engrave from the bottom up – this helps draw any smoke away from the engraving.
• When engraving stained wood, excess smoke and debris can be wiped off the surface of the wood after engraving with a damp cloth.
Mistake 5: Laser Engraver Doesn’t Perform as Fast Anymore
Clean your machine! Much like other types of design equipment, a clean machine produces better results than one that is not properly maintained. But if a drop in performance happens quickly, checking and cleaning the optics may be the first step in correcting the problem.
You should inspecting the optics in the laser—the lenses and mirrors—weekly and cleaning as needed. If you’re cutting materials that produce more residue – like wood or acrylic – you may find your optics need to be cleaned more frequently. Typically, optics are clear gold in color and are bright and shiny. If they are cloudy or have smudges or debris, it’s time to clean them.
The mistakes listed above are common among makers and designers that use laser Cnc engraving machine, especially those just beginning to use the equipment. But as you can see they are easily avoidable if you have the knowledge to correct the mistake.
