The main users of early commercially produced safes were banks, insurance companies, government archives and commercial organizations. Safes made of cast iron, riveted and mortise and tenon technology to complete the box and the door to add cast iron ribs (door or manufactured separately) to increase the strength of the appearance of the safe and locks and leashes appear to be strong outside, locks and mechanisms are relatively simple, so the safes at the time was nothing more than a number of seemingly sturdy iron box, the door thickness is generally 1/2 inch (12 mm).
The process of making a safe is very similar to the process of making a dress in a tailor's store, first of all, let's take a look at the flow chart of the production of safes:
Steel plate material ---> sheet metal forming ---> welding processing ---> surface treatment ---> assembly ---> general inspection ---> packing ---->. Inventory
From the above table we may not be too clear understanding of the production process of the safe, the following we detailed to understand the significance of each process, so that we have a deep comprehension of the production process of the safe:
Steel plate material: as we all know, the raw material of the safe is made of steel plate. Our first process is to purchase over a large sheet of steel through the shearing machine, cut into a piece of small plates we need, in order to facilitate the next step of the process, which is like making clothes, first of all, is to cut the large cloth into collars, cuffs, and other needs of the small square.
Sheet forming: the small plate through a variety of punching machines, molds, bending machines and other machinery and equipment, processing the safe required by a variety of components, such as: the door plate, the back of the box, the bottom plate, a variety of institutions. As, for example, making clothes cut small squares of cloth into a variety of collars, cuffs and other preliminary shapes.
Welding process: the molding of a variety of sheets through the technology of welding, a variety of accessories that have been molded around a box with a door. Through such a process, basically has set up the preliminary framework of the safe. Similar to making clothes, all kinds of molding of small materials through the sewing machine to sew up, forming the basic molding of the clothes.
Surface treatment: through a variety of processes to refine the blank of the safe, and finally the entire process of spraying the surface of the safe. As the welded safe is relatively rough, we have to grind, slag, because the surface of the safe and rust spots, oil, so we have to phosphating treatment to achieve the purpose of de-oiling and de-rusting, due to the rough surface of the safe blank, so in the surface like making furniture to scrape putty gray, and polished smooth, and finally high-temperature electrostatic spraying treatment, the surface of the formation of the paint. This process is similar to the sewn clothes ironed flat, cut off the excess stitching the same reason.
Assembly: assembly is the composition of a variety of safe locks and accessories and other elements of the combination process, so that the formation of a complete safe can be used. If the locks with an electronic combination lock is called electronic safe; if the locks with mechanical locks called mechanical safe; if the fingerprint locks called fingerprint safe. Assembly of more accessories, including casters, locks (door locks, emergency locks, combination locks), operating panels, institutions (including bolts, handles, etc.), back cover, mounted accessories (drawers, flannel, stickers, manuals, partitions, etc.). Just as the final assembly procedures such as making clothes that need to be pinned on the buttons, marking on the clothes and so on.
General Inspection: General Inspection is to check the quality of the safe process, the production of the safe is in line with the requirements of the company's initial design, whether there is a variety of missing accessories, paint is in line with standard requirements, the use of flexible, anti-theft performance is up to standard, and so on. This process is very important, if the problem of the safe is not checked out, it will flow into the market causing losses, customer complaints and so on. The total inspection here is the last full-project inspection, in fact, the safe in the production process of each process needs to be inspected, which is called process inspection, outsourcing processing parts also need to be inspected, which is called outsourcing inspection. In short, the total inspection is one of the important means of quality control.
Packaging and warehousing: this process is the last process of the production of safes, the inspection of qualified safes for packaging, so that it meets the needs of transportation, storage, etc., this link is also a very important process, a lot of safes in the market paint bruises, damage to the accessories of the factors are often due to the packaging, transportation, caused by the irrational. Therefore, even at the end of the sales terminal should be on the transportation of products, loading and unloading special care, the choice of the warehouse should give full consideration to ventilation, dry, leakage of rain and other circumstances, so as to avoid moisture, damage to the product.
