How to realise that the lock you use is safe The largest door lock manufacturer is only serving what is a top priority for most people no matter where they are located in the world. The earliest reference to locks is in the Old Testament and locks were being used even by Egyptian pharaohs in their tombs. Security is something which has been always around maybe even when a man was still roaming around the African plains in groups. The latest in security is provided by floor spring suppliers which are best for glass doors as they are virtually invisible. Locks are manufactured as per grades from low to high security. The floor spring locks are on the higher side of the spectrum and are used on other wooden and metal doors. They are suitable for both outdoor and indoor uses and perfect for any kind of floor. A normal lock is usually a five tumbler lock made up of strong metals. The internal mechanisms are generally made up of die-cast zinc or brass and the outer casing and cam or tongue to secure the lock are made up of brass, steel, nickel or other durable alloys. The first step of any lock manufacturing process starts with understanding the need of the customer and designing a suitable lock for it. The designing of the locks is a time-consuming process. The next step is to make a key for the lock. This is made by cutting ridges on a blank key. Each key has five bumps that are cut at different levels. The levels are then given a number as per their height for each level that serves as the key combination. This is done as per a random list and each key is cut differently unless the customer needs a master key for his chosen set of locks. The internal mechanisms are manufactured next and the machinery is fit in a particular order. The parts themselves are cast, grooved, ridged, jewelled, polished before assembly into the lock. The tiny parts found in the interior of the locks are manufactured to respond to an exceedingly fine tolerance. Precision tools are employed at this stage to cut the metals as per the design to 0.001 of an inch. Further die casts produce other parts of the lock like the cylinder or plug, guard plates, washers, bolts, casings as per the approved design and further machined. Even a lowlevel lock has around thirty separate parts that require a variety of different tools and the whole process may sometimes take several weeks. Once all the parts are ready, the locks are assembled by hand. The worker adds a tiny spring sometimes sourced from floor spring suppliers and assembled with smaller tools. The plug is added as per the key combination and the other parts are attached with snaps or screws to build up the entire lock. A skilled worker may not have gone through any special training other than what they learn on the job and are definitely not professional locksmiths at any small or at the largest door lock manufacturer in India.
