MEASURING METAL STRENGTH (TENSILE & IMPACT STRENGTH)

When selecting a metal for a specific project, one of the most important considerations – especially when it comes to structural applications – is tensile strength and impact strength. Knowing what these mechanical properties are and how to evaluate them is essential to selecting the correct metal for your project. What Is Tensile Strength? Tensile strength is a value that indicates a metal’s ability to resist deformation and failure when loads are applied that pull it apart (known as tensile loads). Tensile strength is typically quantified through units of pounds per square inch (PSI) or pascals (Pa). There are 3 different types of tensile strengths: Tensile yield strength Ultimate tensile strength Fracture tensile strength The yield strength is the strength a metal has before it begins to plastically deform. The ultimate tensile strength is the maximum tensile strength a metal has, and it typically is found after plastic deformation has begun to occur. The fracture te...

Types of CNC Drill Bits

Computer controls and automation can greatly enhance certain manufacturing capabilities. Under computer numerical control (CNC) parameters, tasks that were formerly considered impractical can be accomplished quickly and with a high degree of precision. CNC programming can be designed to match multiple production needs, allowing an automated machine to specialize in a range of fabrication projects. Despite the expanding role of computer controls, CNC-based production is still dependent on its machinery. This makes selecting the appropriate components and machine tools a priority regardless of the level of automation in a system. In the case of drilling machines, such as mills and routers, the type of drill bit used can be a significant influence on the final product. CNC programming can control the feed and depth rate in a drilling cycle, as well as the repetition of specific drilling operations, but choosing a well-suited drill bit remains the manufacturer’s decision. Twist and...

Everything You Need To Know About Injection Molding

图片
What is Injection Molding: Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession. Why Use Injection Molding: The principal advantage of injection molding is the ability to scale production en masse. Once the initial costs have been paid the price per unit during injection molded manufacturing is extremely low. The price also tends to drop drastically as more parts are produced. Other advantages include the following: Injection Molding produces low scrap rates relative to traditional manufacturing processes like CNC machining which cut away substantial percentages of an original plastic block or sheet. This however can be a negative relative to additive manufacturing processes like 3D printing that have even lower scrap rates. Note: waste plastic from injection molding manufacturing typically comes consistent...
