Marking Stencils Stencil is a cut-out form for an alphabets, numbers, symbols and illustrations. Embossing and Marking Stencils provide quality of work and save plenty of time. Stencils are available in a wide variety of materials and fabrication methods. Stainless steel and plastic are the most commonly used materials. Thickness ranges from a few millimeters to 0.040 depending on the components to be placed. Marking Stencil Material Stencil material can be a critical variable in the stencil printing process. The dynamics of deposition and release are quite different between metal and plastic stencils. Plastic Stencils Plastic stencils have several advantages over metal stencils. Plastic stencils are easy to clean and store. There is no rust problem with plastic. Plastic stencil weighs less than metal stencils. Typically plastic stencils are much thicker than metal stencils and small apertures may require more aggressive cleaning such as high pressure spray or ultrasonic methods. Plastic is more durable and flexible material. Mylar is a special type of plastic usually used in making plastic stencils. It has one side shinning and other side dull to create difference between stenciling side and underside. The plastic stencil has disadvantages, as well. Since the apertures in the plastic stencil are drilled, only round shapes are possible. Also, since plastic stencil technology is new, they are not as widely available as are stainless steel stencils and may be more expensive. Finally, the plastic stencil may be harmed by metal squeegee blades and, therefore, only polyurethane or special blades (provided by the stencil manufacturer) are advised. Plastic stencils have been recommended when the application requires a wide range of dot heights in a single print pass. Metal Stencils Metal stencils are available at comparatively low prices. There is a complete freedom of aperture geometry. Metal stencils are recommended when only small dots are needed.
