  When it comes to heating and melting metal, there are a number of options. Businesses can use induction heating , convection heating, radiant heat, and open flames to get the results they are looking for. For many purposes, using an induction forge during the induction heating process comes with a number of advantages over the other methods. Here are a few reasons this is the best way to go: The consistency cannot be beat. Unlike with other heating processes and methods, when you use induction heat er , the consistency is much better. Torch heat and open flame heat are not nearly as consistent as using tools such as an induction forge and an induction coil. This kind of heating can produce remarkably consistent results time after time. You lose the variation or any guesswork you have with other methods. In today ’ s world where solid-state systems are used, by using this form of heat, you get results that are much more uniform. When working with advanced induction heating eq...

  The principle of straightening is the use of an external force such as pressure or heat to straighten a deformed sheet of metal into its correct shape. The  principle of straightening  is the use of an external force such as pressure or heat to straighten a deformed sheet of metal into its correct shape. To explain how the forming process works, we can first think of sheet metal as a collection of many parallel fibers. In normal circumstances, the fibers are placed in parallel in a sequence that strengthens the sheet metal and keeps it parallel. Here are two methods of straightening that may help to make the sheet metal flat again.   The first is a manual straightening method using a hammer. Suitable for the reshaping of small workpieces, it is the most convenient method that can be easily achieved by everyone using metal straightening tools and operational progress. You will need to apply some oil to the sheet metal hammer before it is hammered into the correct sh...

It is important to understand the difference between the gate valve and the globe valve when you need to choose valves. They are both popular valve types and even look similar, but they are used in completely different places. Basic knowledge of the globe valve The globe valve  can be used to start, stop and adjust the flow, and the name comes from the shape of the valve body. The tapered plug enters and exits in the fluid flow during operation. The flow rate depends on the distance between the plug and the valve seat. It is necessary for operators to be careful and not to turn the valve stem too far, as this will damage the valve seat.     It provides greater resistance to fluid flow and has a higher pressure drop even when the valve is fully opened. The bronze pressure regulator also has a great performance in the pressure-reducing process. Apart from that, the OEM brass  ball valve  also has a good flow regulation function.   Basic knowled...

  Each time the vehicle repair and maintenance, need to do a good job of preparation beforehand, in order to avoid some trouble generated.   (1) Dress code. When repairing a car, be sure to wear clean work clothes, must wear a work cap, wear safety shoes.   (2) Vehicle protection. Before the repair work, prepare the radiator grille cover, wing protection cover, seat surface protection, floor mats, steering wheel cover and gear lever cover and other items.     (3) Safe operation of lifting equipment. When two or more people work together, be sure to check each other's safety conditions. When working with the engine running, ensure that the workroom is ventilated to expel exhaust gases. Always wear safety equipment when servicing hot, high-pressure, rotating, moving or vibrating parts, and be careful not to injure yourself or others. When jacking up a vehicle, always use a safety base to support the specified area. When lifting a vehicle, use safety equipment. ...

Handheld inkjet printer Machine  is used to print lot numbers, manufacturing dates, expiration dates, MRP and other details that provide product details. Handheld inkjet printer working principle. Handheld coding, the nozzle technology belongs to the thermal bubble inkjet technology, the nozzles use semiconductor film technology, laser technology and high precision coating technology to form multiple nozzles with a diameter of approximately 50 microns. These nozzles are arranged in high density. Upon receipt of a heating signal, the ink is heated by an electric current to around 260°C in a very short time. The localised ink is heated to form bubbles that expand and the ink is ejected to form the text. Importance of Batch Coding. The batch/lot number or lot number should be placed on the product in accordance with national regulations. This number is important because it may be needed, especially if the product is recalled or the quality of the product in the batch is not satisfacto...

Steel coils refer to a finished steel product that’s manufactured out of slabs. Slabs are considered semi-finished steel materials made from ingots. Producing steel coils out of slabs can be done in different ways — hot rolling,  cold rolling , or electrolytic tinplate (EPT). Once all of the major production processes have been completed, the resulting rolled material can now be used in various industries for assembly or further fabrication. Knowing this, steel coil uses can vary depending on the industry, but some of its most popular and widely-known applications include pipe-manufacturing, structural steel members, electronic components, consumer goods, automotive parts, and many more. As mentioned before,  steel coil manufacturing  involves taking a slab and then placing them into a continuously rolling machine that reduces its thickness. The result is durable, high-grade, ductile, and high-strength steel sheets that are wound into coils. Read on to learn more abo...

  There are   different laser cleaning machines   with different power levels available. The choice of laser power depends on the material you want to clean and the amount of rust or dirt on the surface of the material.   In addition, when deciding on the  best laser cleaning machine  for your business, you have a choice of machine size, portability and price. When choosing a laser descaling machine look for the following.   Laser power Laser cleaners are typically available in 3 power categories. Although the exact specifications vary from machine to machine, the power categories will give you a general idea of the best machine for your requirements. As the power increases, the speed and amount of rust removal increases.   Low power cleaners Low power laser cleaners range from 20W to 100W laser power. This type of power is ideal for light rust removal where speed is not very important. It is also ideal if you have a relatively small setup and the...

  Basically, laser marking is a process that uses a concentrated beam of light to create a precise and permanent mark on a range of surfaces, including materials like steel, titanium, copper, ceramics, glass, plastic and wood.   Laser marking machines  can create marks such as serial numbers, bar codes and graphics. There are several things you should consider when choosing a laser marking machine.   Which materials do you want to mark? Seeing as a UV laser marking machine can mark more materials, it is often the preferred choice. But your choice of machine will largely be dependent on the exact materials you need to engrave. Here are the key materials you can use with each machine.   UV lasers can mark: · Some metals · Some stones · All plastics · All glass · All papers · All leathers · All woods · All ceramics ZJ-MKBX Laser Marking Machine Is a UV laser marker or a fibre laser marker more suited to your requirements? The two main  types of laser marking m...

Extrusion, as you know, is a process whose objective is to achieve the cooking of the mixture of raw materials and ingredients, giving it the shape of a croquette to facilitate its subsequent handling. In this article we will talk about  cold extrusion  specifically: what are its benefits for food and the advantages and disadvantages of the process. ​ What is cold extrusion? Cold extrusion is a process by which the temperature of the food does not increase and products of high density and humidity are obtained, such as cookies, muffins or sweets. The main difference is, as the name of this process indicates, in the temperature. Since in the "traditional" extrusion more than 100º C is needed to achieve the desired result. Currently, at an international level cold extrusion is used for the production of: • Candies • Supplements • Medicines Furthermore, the results can be obtained in different formats: • Cool • Damp • Half damp • Dry • Freeze-dried • Dehydrated   What is the...
