Pull-tight Seal

picture info	Pull-tight Seal {{notable, date=October 2016 A pull-tight seal (or pull-up seal) is a disposable tamper-evident seal which restricts access to closed objects for those who do not have access. The tightening seal is needed in cases where the use of more sophisticated security measures are impossible or impractical. The seal is not established for the physical protection of the object which is sealed, but for indicating attempts to interfere. Layers of security The tightening seal (Pull-up type) uses multiple layers of security: an individual number; an individual logo; protection for the latching mechanism against direct access; the ability to control of a condition of the locking mechanism (collet); a material of collet production; labeling method (pad printing or laser marking). Any attempt to circumvent one of these protections must be visible easily and immediately. Access control The seal gives users the opportunity to provide access control to objects such as warehouses, veh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Tamper-evident Technology Tamper-evident describes a device or process that makes unauthorized access to the protected object easily detected. Seals, markings, or other techniques may be tamper indicating. Tampering Tampering involves the deliberate altering or adulteration of information, a product, a package, or system. Solutions may involve all phases of product production, distribution, logistics, sale, and use. No single solution can be considered as "tamper proof". Often multiple levels of security need to be addressed to reduce the risk of tampering. Some considerations might include: Identify who a potential tamperer might be and what level of knowledge, materials, tools, etc. might they have. Identify all feasible methods of unauthorized access into a product, package, or system. In addition to the primary means of entry, also consider secondary or "back door" methods. Control or limit access to products or systems of interest. Improve the tamper resistance by making tampering more difficult ...

picture info	Collet A collet is a segmented sleeve, band or ''collar''. One of the two radial surfaces of a collet is usually tapered (i.e a truncated cone) and the other is cylindrical. The term ''collet'' commonly refers to a type of chuck that uses collets to hold either a workpiece or a tool (such as a drill) but has other mechanical applications. An external collet is a sleeve with a cylindrical inner surface and a conical outer surface. The collet can be squeezed against a matching taper such that its inner surface contracts to a slightly smaller diameter, squeezing the tool or workpiece to hold it securely. Most often the collet is made of spring steel, with one or more kerf cuts along its length to allow it to expand and contract. This type of collet holds the external surface of the tool or workpiece being clamped. This is the most usual type of collet chuck. An external collet clamps against the internal surface or bore of a hollow cylinder. The collet's taper is internal and the ...

picture info	Pad Printing Pad printing (also called tampography) is a printing process that can transfer a 2-D image onto a 3-D object (e.g. a ceramic pottery). This is accomplished using an indirect offset (gravure) printing process that involves an image being transferred from the cliché via a silicone pad onto a substrate. Pad printing is used for printing on otherwise difficult to print on products in many industries including medical, automotive, promotional, apparel, and electronic objects, as well as appliances, sports equipment and toys. It can also be used to deposit functional materials such as conductive inks, adhesives, dyes and lubricants. Physical changes within the ink film both on the cliché and on the pad allow it to leave the etched image area in favor of adhering to the pad, and to subsequently release from the pad in favor of adhering to the substrate. The unique properties of the silicone pad enable it to pick the image up from a flat plane and transfer it to a variety of surfa ...

picture info	Laser Engraving Laser engraving is the practice of using lasers to engrave an object. Laser marking, on the other hand, is a broader category of methods to leave marks on an object, which in some cases, also includes color change due to chemical/molecular alteration, charring, foaming, melting, ablation, and more. The technique does not involve the use of inks, nor does it involve tool bits which contact the engraving surface and wear out, giving it an advantage over alternative engraving or marking technologies where inks or bit heads have to be replaced regularly. The impact of laser marking has been more pronounced for specially designed "laserable" materials and also for some paints. These include laser-sensitive polymers and novel metal alloys. The term laser marking is also used as a generic term covering a broad spectrum of surfacing techniques including printing, hot-branding and laser bonding. The machines for laser engraving and laser marking are the same, so that the two terms are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Bank Reserves Bank reserves are a commercial bank's cash holdings physically held by the bank, and deposits held in the bank's account with the central bank. Under the fractional-reserve banking system used in most countries, central banks typically set minimum reserve requirements that require commercial banks under its purview to hold cash or deposits at the central bank equivalent to at least a prescribed percentage of their liabilities, such as customer deposits. Such sums are usually termed required reserves, and any funds above the required amount are called excess reserves. These reserves are prescribed to ensure that, in the normal events, there is sufficient liquidity in the banking system to provide funds to bank customers wishing to withdraw cash. Even when there are no reserve requirements, banks often as a matter of prudent management hold reserves in case of unexpected events, such as unusually large net withdrawals by customers (such as before Christmas) or bank runs.

picture info	Zip Tie A cable tie (also known as a hose tie, zip tie, or tie wrap) is a type of fastener for holding items together, primarily electrical cables and wires. Because of their low cost, ease of use, and binding strength, cable ties are ubiquitous, finding use in a wide range of other applications. Cable ties were first manufactured by Thomas & Betts under the brand name . The common cable tie, normally made of nylon, has a flexible tape section with teeth that engage with a pawl in the head to form a ratchet so that as the free end of the tape section is pulled the cable tie tightens and does not come undone. Some ties include a tab that can be depressed to release the ratchet so that the tie can be loosened or removed, and possibly reused. Stainless steel versions, some coated with a rugged plastic, cater for exterior applications and hazardous environments. Design and use The most common cable tie consists of a flexible nylon tape with an integrated gear rack, and on one end a rat ...
