Top 10 Factors Affecting the Quality of Injection Molds

图片
    Mold manufacturing  is a complex process, from design, processing, assembly, commissioning, and other steps, to the final real use, in the whole life cycle, there are 10 main factors that affect the quality of the mold as follows.   1. Mold steel Steel is the decisive factor of mold quality, and choosing reasonable steel is the most important. The criteria for choosing steel are   ①The requirements of injection materials different plastics to use different steel, such as the requirements of high polish, corrosion resistance, etc..   ②Price steel properties can be good, not the more expensive the better; taking into account the cost factors of the mold, mold steel should be used and mold life corresponding to the material, to avoid unnecessary waste; general P20 material life of about 300,000; 2738 material in 500,000 no problem, H13/2344 usually in 800,000-1,000,000 or more, can be selected according to the situation.   ③Surface treatment The surface treatment of the mold is also v

Is Ammonium Sulfate A Good Fertilizer?

    What is Ammonium Sulphate Fertilizer?   Ammonium sulfate  fertilizer contains ammonium, nitrogen and sulfur in the form of sulfate that plants can take. Ammonium sulfate fertilizer has a crystalline structure, it is known as "sugar fertilizer" among farmers. Sulfur in the form of sulfate it contains is in a form to provide the needs of plants completely. As nitrogen is formalized in the form of ammonium, it increases the plant's need for phosphorus intake and provides productivity like all fertilizers applied before planting. What are the Benefits of Ammonium Sulphate Fertilizer, Known as Sugar Fertilizer? Economically suitable ammonium sulphate fertilizer also provides fast results after application. Thanks to its sulfur, it facilitates the plant's uptake of nitrogen and provides support to the root, leaves, stem and branches of the plant during development period. It provides efficient products by making the plant resistant to diseases. Depending on the changing

Understanding Threads & Thread Mills

图片
  CNC Pipe Threading Machine   Thread milling can present a machinist many challenges. While  CNC Threading Machines  are capable of producing threads with relative ease, there are a lot of considerations that machinists must make prior to beginning the job in order to gain consistent results. To conceptualize these features and choose the right tool, machinists must first understand basic thread milling applications.   What is a Thread? The primary function of a thread is to form a coupling between two different mechanisms. Think of the cap on your water bottle. The cap couples with the top of the bottle in order to create a water tight seal. This coupling can transmit motion and help to obtain mechanical advantages.  Below are some important terms to know in order to understand threads. • Root – That surface of the thread which joins the flanks of adjacent thread forms and is immediately adjacent to the cylinder or cone from which the thread projects. • Flank – The flank of a thread

Features and operation methods of EPS foam molding machine

    The EPS foam molding machine has the characteristics of complete functions and convenient parameter adjustment. Closed mold, feeding, foaming, mold, gas and automatic control, but also allows computer control to produce foam products with multiple heating methods Old machine molds that can be used in complete soil environments, in the case of no changes in plants, the The machine can be in good condition, so that the products meet the requirements of automatic vacuum forming machine. The foaming machine has compact structure, space saving, reliable performance, convenient maintenance, labor saving, steam quality saving, and raw material saving. EPS foam molding machine   is semi-automatic learning, a little bit, no training, every 2-4 operating machines. The foam molding machine adopts imported hydraulic system at the same time, and increases the clamping force to improve the speed of the mold, the molding cycle is short, the molding machine is automatic molding machine More energy

The Difference between Globe Valve And Butterfly Valve

图片
    Globe valve  and butterfly valve are two common valves used to control the flow in the pipeline. The disc of the globe valve moves in a straight line along the centerline of the seat to open and close the valve. The stem axis of the globe valve is perpendicular to the sealing surface of the valve seat, and the opening or closing travel of the stem is relatively short, making this valve very suitable for cutting off or adjusting and throttling as the flow.   Butterfly valve's plate-shaped disc rotates around its own axis in the body to cut and throttle the flow. The butterfly valve is characterized by its simple structure, small volume, lightweight, the composition of only a few parts, and rapid opening and closing by rotation of only 90°, fast control of fluid media, which can be used for media with suspended solid particles or powdery media. Here we'll discuss the difference between them, if interested, please read on.   Different structure The globe valve is composed of t

Which type of scaffolding do you need?

图片
  In addition to construction, there is also maintenance and repair tasks when it comes to buildings. Contractors choose scaffolding systems depending on the type of work they have at hand – this article explores the options on offer. Steel Scaffolding Steel scaffolding is made up of steel tubes which makes it quite a robust scaffolding system. Such a scaffold can be used for work on a building’s exterior. It can reach great heights without affecting the safety of the scaffold, and it can also withstand harsh weather conditions. It can carry heavy loads therefore increasing efficiency and saving time. Suspended Scaffolding As the name suggests, suspended scaffolding refers to a scaffold system that hangs from the ceiling of a building. These scaffolds are normally used for interior projects, such as painting, electrical work, repairs, etc. They can reach great heights and complete the work by employing a quick and efficient scaffold that is easily adjusted according to the situation.

What are the application scenarios of infrared lenses?

  What are the application scenarios of infrared lenses corrected by special materials? Come and learn about the relevant content with the editor of Fuqing Optical Lens! 1. All-weather surveillance camera The most minor use of  infrared lenses  is to complete all-weather surveillance. The optically corrected infrared lens can focus clearly during the day, and usually needs to be refocused in the morning. The infrared lens corrected by a special material can make visible light and infrared focus to the same focus, so after the focus is clear during the day, the infrared lens is turned on at night. The fill light can still image clearly. Second, through the fog Fog penetration originates from the monitoring requirements in long-distance and complex environments. Fog is composed of coarse particles floating in the air. The more particles per unit volume, the denser the fog. Visible light has shorter wavelengths and cannot penetrate mist, which is why visibility is very low on foggy mornin

What is a rectifier module?

图片
  A rectifier module is a part of all the electric equipment composed of diode or diodes, which convert alternating current (AC) to direct current (DC). Diode is a device that allows flow of current through it only in one direction and often it is used to design rectifiers. Rectifier diode acts as a rectifier, with the main function of changing AC to DC, and is broadly used in power rectifier circuits. A rectifier module   comes in various physical forms such as vacuum tube diodes, solid state diodes, silicon-controlled rectifiers, valves of mercury arc and silicon-based semiconductor switches. Almost all the rectifiers contain more than one diode in particular arrangements. Basically, a rectifier module produces DC that encloses active current and voltage, which are then adjusted into a type of constant voltage DC, though this varies depending on the current's end use. The current flow is uninterrupted in single direction, no current is permitted in another direction. Rectifier mo
