Geometric tolerances are critical for ensuring accuracy and precision in manufactured parts. One important type of geometric tolerance is profile tolerance, which regulates the form of curves, curved surfaces, and other non-flat features. This article provides an in-depth look at profile tolerance, explaining the different types, how to properly indicate profile tolerance on drawings, and examples of using profile tolerance as both a form tolerance and positional tolerance. For those unsure of how to utilize profile tolerances, this guide serves as a helpful reference for properly speci......

Carbide rotary burrs that are attached and used with manual rotary tools such as hand grinders and air grinders have various blade shapes, sizes, and cut types. Each type has different applications and preferred machining shapes, allowing a wide range of machining when used properly. This article introduces the types and characteristics of carbide rotary burr cut shapes, as well as suitable materials for each cut. Types of Cuts for Carbide Rotary Burrs The pattern of irregularities on the blades of carbide rotary burrs is called the cut (blade type). There are three major ty......

Plastics are incredibly versatile materials that are utilized in a vast array of products and applications. Polytetrafluoroethylene (PTFE) and polyetheretherketone (PEEK) are two of the most commonly used high-performance thermoplastic materials in industrial manufacturing applications. Both plastics offer unique properties that make them well-suited for various engineering applications. While both offer exceptional properties, there are key differences between PEEK and PTFE plastic that make each suitable for specific purposes. In this post, we will provide an overview of PEEK and PTFE......

Drop forging is a manufacturing process widely used to produce powerful and durable metal parts for a variety of industries. This guide will provide an in-depth look at drop forging, including its definition, process steps, types, die design considerations, advantages over other forming methods, and common applications. What is Drop Forging? As defined by American Vanadium, drop forging is a “metal forming process where a hot or warm metal workpiece is placed on a die and then compressed by a powered hammer or press.” Compared to other forging methods like press for......

Here we list all Casting GD&T Charts covering all geometric tolerances (straightness, flatness, roundness, parallelism, perpendicularity tables)!   Casting Geometric Tolerance Charts In metal casting and manufacturing, maintaining tight tolerances is crucial for ensuring the quality and functionality of cast parts. Casting tolerances define the allowable variation in dimensions and geometries of a cast part. Common casting tolerances specify limits on straightness, flatness, roundness, parallelism, and ......

We compare and discuss the differences between PA6 and PA66 engineering plastics in terms of Chemical Composition, physical properties, application, injection molding process, price, etc. Differences Between PA6 (Nylon 6) & PA66 (Nylon 66) Plastic Material Polyamide, in short PA, commonly known as Nylon, is a general term for high polymers with amide functional groups in the repeating units of the polymer backbone. PA is the largest in terms of production, most diverse in varieties, and widely used among the five major engineering plastics. It is commonly used in......

“MJF” stands for “Multi Jet Fusion,” which is an abbreviated term for a specific additive manufacturing technology used in HP’s 3D printers. MJF has gained popularity in recent times compared to other 3D Printing methods, it enables the transition from rapid prototyping to direct manufacturing of final products. This technology allows for the production of robust and highly detailed end products while maintaining high productivity. In this discussion, we will explore what is Multi Jet Fusion, how it works and why it is suitable for mass production, the leve......

Steel is one of the most common materials used in construction and manufacturing. One of the common steel materials is “ordinary carbon steel” or “low carbon steel”, also known as “mild steel”. Due to its excellent workability, weldability and relatively low cost, mild steel has become an indispensable choice in many industries. Whether you’re in home repair, construction, or manufacturing, it’s crucial to know how to properly use and maintain mild steel. This guide is designed to provide you with comprehensive information about mild steel......
