Because of their combination of properties, castability and cost effectiveness, gray and ductile iron are the dominant metals (based on weight) produced in metalcasting facilities today. When sourcing, designing and purchasing ductile and gray iron castings, a number of variables must be considered when choosing between the two. This comparison of gray and ductile iron will help designers and purchasers decide which alloy is suitable for a specific cast component. Gray iron is the preferred material when seeking low-cost, complex geometries with strength and high density. Gray iron can be used for a wide range of applications, from table legs and bases to large fountains and building facades. Gray iron is particularly good for applications in which vibration damping is required, such as engine blocks and frames for manufacturing equipment. For higher strength applications, ductile iron can be used. Ductile iron, because of its strength and ductility, often is specified in severe applic

CNC cylindrical grinders are also called CNC grinders or  CNC cylindrical grinding machines . They are essentially the grinding machines that are controlled by the CNC system. CNC stands for Computer Numerical Control which refers to an automated unit that controls the machining tools by a computer. A cylindrical grinder has its name from the grinding spindle that has a cylindrical figure; a machine as such performs grinding works by the rotary movement of the grinding tool which is driven by the spindle. The grinding work that is conducted by a CNC cylindrical grinder goes this way: the operation is pre-programmed on a computer and the CNC system gives a series of instructions to the grinder to carry out the very operation. The programming process is referred to as CAD which stands for Computer-Aided Design. The most popular CAD software to date is AutoCAD. Since the movement of the grinding tools as well as the work pieces is precisely controlled and executed, the end result of the o

Everyone has used corrugated boxes. But have you ever wondered how they are made? Does it need to be folded by hand or can it be done simply using a  carton forming machine ? You should know that corrugated boxes are made from trees. Below we will discuss the box manufacturing process step by step. Steps in Box Manufacturing 1. The tree While we ideally look for recycled cardboard for box production, at some point, a cardboard box begins life in the form of a tree. Typically, the trees used for box manufacturing are cork trees such as pine and fir. They are chosen because they have long fibers that help create a smooth surface for the cardboard and create the tension that adds strength. Many manufacturers will choose wood from sustainable and managed woodlands; this means that any trees that are cut down will be replaced to help maintain the ecosystem of the forest. Depending on the tree used, the paper and board created will have different colors. For example, silver birch will produc

Although printing on  cosmetics containers  and packages looks the same at first glance, there are actually various printing methods.   The following items are explained here. ● Silkscreen printing ● Pad printing ● Offset printing ● Hot-dry printing ● UV printing ● Inkjet printing ● Coating ● Vapor Deposition  ● Hot stamp printing ● Shrink  ● In-mold printing ● Adhesive labels *The methods employed differ depending on the container (material) manufacturer, finish, quality, etc.     1. Silkscreen printing (silk printing) A technique for printing by using a silkscreen made of nylon, Tetoron, or other synthetic fiber (silk used in the past) attached to a frame, filling the mesh of the silk with emulsion in areas not to be printed, and rubbing the paint with a squeegee while applying pressure. The printing process is repeated by printing one color and drying, and a printing plate for the number of colors is required. *Color compositing is not possible. The printed ink layer is thicker and

  Pruning and maintaining trees is an important part of their health and productivity. Having a tree pruner on hand is a smart way to keep your trees looking great. Because ladders can be dangerous, having a   telescopic tree pruner   allows you to trim branches of all heights from the safety of the ground.   Before you choose to  buy any telescopic tree pruner , you need to decide whether you want a manual or gas-powered pruner. Gas-powered telescopic tree pruner models are heavier and are suitable for bigger jobs, such as cutting larger branches. Manual telescopic tree pruners are used for smaller jobs and cutting thinner branches.   Manual pruning shears are more labor intensive than gas-powered pruning shears, but they are also cheaper, more environmentally friendly and lighter in weight. Most people will be happy with a manual model, but a commercial tree pruner or gardener may want to consider using a gas-powered model.   Telescopic Tree Pruner   If you are buying a manual telesc

    Different terms used for  arresters  are sometimes confusing even professional engineers and electricians use them interchangeably. Now let’s discuss all these arresters in details.   Table of Contents   What is a Surge Arrester? What is a Lightning Arrester? Main Differences between Surge Arrester and Lightning Arrester Should You Use Surge Arresters or Lightning Arresters?   Surge Arrester   1. The  surge arrester  will be installed nearer to the equipment to be protected and the transmission tower line enter in to the substation point. 2. It protects against high voltage transient (example: lightning strike on the transmission conductor) typically, it is indirect protection of lightning strikes. 3. It should be installed each phase of the circuit. i.e if you have 2 parallel switch yard then you should install 6 number of surge arrester (first run 3 phase and second run 3 phase) . Lightning arresters   1. The lighting arrester is doing the exact duty of surge arrester from outsid

What is a powder filling machine? Powder filling machines  are essential when filling a wide variety of free-flowing and non-free-flowing powder or granular products. Powder products that are not sticky, such as granulated sugar or table salt, are defined as free-flowing. They don't compress easily when extra pressure is applied, and they don't hold their shape even when manipulated. In contrast, non-free-flowing powdered products, such as milk powder and brown sugar, can be compressed and retain their shape when handled. There are many  types of powder filling machines , depending on the machine design and configuration for the level of automation for quantitative or volumetric filling. Some fillers can only handle free-flowing or non-free-flowing powders, but some cannot handle both. In addition, powder filling machines fill powder products into different types of packaging, including: Bags, Bag-in-boxes, Cans, Jars, Vials, Bottles... Advantages of powder filling machines If
