In the realm of mechanical engineering, various standards govern threads, and it’s time to organize and summarize them. Threads, whether metric or imperial, straight or tapered, sealed or unsealed, internal or external, with angles of 55 or 60 degrees, often…
MIG and TIG welding are two popular welding methods that share similarities, such as utilizing an electric arc and a shielding gas. However, there are distinct differences, particularly in the type of welding electrodes employed to establish the arc. MIG…
Ribs in injection-molded parts add strength and stiffness, making the part more rigid. Without ribs, we’d need a thicker, heavier part to achieve the same stiffness. To avoid excessive sinking and weight, the ribs’ thickness should be about 50% of…
Some undercut features are inevitable In the injection molding process, it’s important to avoid designs that have undercut features, as they can cause problems when removing the product from the mold. But sometimes, these undercuts are necessary for the product…
Choose the right material Choosing the right plastic material for injection molded parts can be tricky. Factors that need to be considered in most cases include the material’s hardness, strength, density, shrinkage, melting point, and cost. Depending on the usage…
Avoiding Thin Wall Thickness in CNC Machined Parts When designing parts for CNC machining, it is crucial to consider the thickness of the walls. Thin walls can pose a risk of bending and breaking during the machining process. Extensive research…
Fillets and chamfers are two distinct approaches to shaping the meeting edges of two surfaces on a part. Their purpose is to alleviate the presence of sharp edges and corners. A chamfer achieves this by replacing the abrupt change in…

Powder metallurgy (PM) encompasses various methods for creating materials or components using metal powders. By employing PM processes, the reliance on subtractive manufacturing techniques can be minimized or eliminated altogether. This not only decreases material waste but also leads to…
The prototype is the initial sample of a certain product, and rapid prototyping means making samples quickly. In different stages of product development, for different products, the purpose of making samples is different. In general, there are three kinds of…
