Thread galling happens when the bolt and nut threads stick together during tightening. The pressure and friction between the surfaces cause the metal to tear or seize. This is most common with stainless steel, aluminum, and titanium. These materials have sticky properties and tend to weld under pressure without lubrication.

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.

A blind hole is a hole drilled, milled, or bored into a material that doesn’t penetrate through to the other side. Unlike through holes, blind holes have a defined depth and a bottom surface. They are commonly used in applications where a fastener or component needs to sit flush or be hidden within the material.

Springback refers to a material’s tendency to revert to its original shape after being bent. When force bends the metal, it deforms both elastically and plastically. After the force is removed, the elastic part tries to recover. This rebound is what we call springback.

Electrical Discharge Machining (Sinker EDM) is a metal removal process that uses electrical sparks to remove material from the workpiece. This process involves submerging the electrode and the workpiece in dielectric fluid. High-frequency electrical pulses then erode and melt the surface of the piece.

Titanium is lighter, stronger, and more corrosion-resistant than stainless steel. It’s ideal for aerospace, medical implants, and high-performance applications. Stainless steel, on the other hand, is more affordable, easier to machine, and better for everyday use, such as kitchen appliances or construction.

For most projects, aluminum is the better choice due to its lower cost, easier machinability, and lighter weight. However, titanium excels in high-strength applications requiring corrosion resistance and biocompatibility. Your specific project requirements will determine which metal is best suited for your needs.

Laser marking is a process that uses a focused laser beam to create marks on a material’s surface. The laser changes the material’s color or texture, leaving text, logos, or codes behind. It’s fast, clean, and doesn’t require inks or chemicals. This makes it ideal for industries that need durable, high-quality markings. Laser marking is non-contact, meaning the material has no physical wear. The marks are also resistant to fading, scratching, and heat.

Brass drilling differs from other metals because of its unique properties. It’s softer than steel but harder than aluminum, requiring different speeds and feeds. The zinc content in brass creates challenges with chip formation and tool sticking. The correct drill bits, speeds, and lubricants will help you avoid common problems and produce clean, accurate holes.

Fasteners come in many shapes and sizes, each serving a different purpose. To choose the correct fastener, consider material, load requirements, environmental conditions, and ease of assembly. The key is to match the fastener’s characteristics to the needs of your project.

Chamfer and bevel refer to angled cuts on the edges of materials, but there are key differences. A chamfer is typically a straight cut at a 45-degree angle, often used to remove sharp edges and improve safety or aesthetics. Conversely, a bevel can be any angle other than 90 degrees, offering more versatility for various design needs.

5 predominant methods are employed to create aluminum prototypes: CNC Machining, 3D Printing, Die Casting, Aluminum Extrusion, and Sheet Metal Fabrication. Each method offers unique benefits and is chosen based on the prototype’s complexity, desired precision, and production volume.

Comparing alloy steel with carbon steel is a matter of comparing their properties and composition. The varied alloy steel elements make it more versatile and offer improved corrosion resistance. Carbon steel is a more straightforward composition that excels at strength and cost-effectiveness for specific applications.

Bend allowance is the curved length of metal between the bend lines. It tells you how much material is needed in the bend area. When metal bends, it stretches slightly on the outer side and compresses on the inner side. The bend allowance measures that change.

On-demand manufacturing is a process in which products are made only when ordered. Instead of producing large quantities ahead of time, items are created as needed.

This method is more flexible and cost-effective, allowing businesses to focus on smaller production runs. Companies can create products that meet specific customer needs without wasting time or resources on unsold inventory.

Making sheet metal brackets involves three key steps: design planning, material selection, and manufacturing method choice. Each bracket needs precise measurements, appropriate material thickness, and suitable bend angles. The manufacturing process typically includes cutting, bending, and finishing operations.
