Thread galling occurs when the pressure and friction of tightening fasteners cause the metals to fuse. This microscopic welding effect occurs without applying any actual heat. The result is a fastener that is difficult to remove or adjust, often leading to damaged threads or the need to replace the entire assembly.
Press brake forming is a metalworking process. A press brake machine bends sheet metal by pressing it between a matching punch and die. This method allows for precisely shaping metal into various angles and forms. Its versatility and accuracy make press brake forming an essential technique in fabricating metal products with specific requirements.
A punch press is a mechanical press used to create an artificial material. It can range from being small enough to be operated manually and hold a simple die set to a huge CNC (Computer Numerical Control) machine with multi-station turrets capable of holding larger, more complex die sets.
The progressive die stamping method uses a series of station dies within a single tool to bend, punch, cut, and progressively shape the metal strip. As the strip unrolls from a coil, each station performs a specific operation until the component reaches its final form.
Welding thin metal requires a steady hand and the right equipment. We use TIG welding for its precision and control. This method allows us to produce clean, strong welds on even the thinnest metals. We ensure high-quality joins every time by controlling the heat input and using the appropriate filler material.
Metal galling is when two metal surfaces, typically under load and in motion relative to one another, adhere to each other at points of contact. This unintended adhesion can tear the metal surface when the parts are separated or moved, which compromises the integrity and functionality of the components.
CNC engraving uses computer numerical control (CNC) technology to engrave, etch accurately, or letter designs on various material surfaces. The method involves a computer-controlled machine that directs the movement of a cutting tool or laser on the material, meticulously removing layers to create intricate patterns, text, or images.
Copper 3D printing overcomes the limitations of traditional manufacturing by using copper powder. We then fuse the powder using various methods, such as heat, adhesives, or other materials. This process eliminates the requirement to braze and solder components. This innovative process simplifies production and enables the efficient production of complex designs.
A fabricated structure’s integrity depends on the welding joints’ quality. There are five types of welding joints: corner, butt, lap, tee, and edge. Each type has a specific purpose and ensures solid and durable structures. Anyone involved in metal fabrication must understand these joints because they determine the design and functionality of the final product.
Anodizing titanium is a fascinating and straightforward electrochemical process. We can control the thickness on the surface of titanium by immersing it in an electrolyte and then applying an electric current. This thickness determines the titanium’s color, ranging from rich purples to vibrant blues.
Alodine, or chromate conversion, is a chemical process for treating aluminum and other metals. It improves corrosion resistance and provides a good surface for adhesion. The process involves the application of a chemical layer that reacts to the metal surface and forms a protective coating.
Blind holes are holes drilled in a material that does not have an exit from the other side. Designers often use blind holes when they need precision and depth without piercing the entire material.
A centerless grinding process uses abrasive cuts to remove material from a workpiece’s outside diameter. Centerless grinding is different from traditional grinding because it does not require that the workpiece be mounted or fixed. The material can be removed quickly, producing a smooth and precise finish.
Aluminum milling involves removing material to produce the desired component or part. CNC mills (Computer Numerical Control), high-speed precision machines that can produce complex designs, are used to shape aluminum.
A typical welding defect is the undercut. This occurs when the weld does not adequately cover the base metal. This flaw could significantly weaken structural integrity, making the weld joint more vulnerable to failure.
Bevel welds are weld joints made between metal pieces that are not parallel or perpendicular to each other. By beveling at least one piece, you can create a larger surface, which allows for a more robust and deeper weld. This technique is crucial for thick materials, where strength and integrity are essential.
