Salt spray testing, also known as salt fog testing, is a method used for corrosion testing. It exposes metal parts to a fine mist of saltwater solution inside a controlled chamber. The goal is to create an accelerated corrosive environment. This test helps evaluate how coatings, platings, and surface treatments withstand harsh conditions.
Machining is a subtractive process. It removes material from a solid block, often metal, to create specific shapes. This is done using cutting tools, grinding wheels, or electric discharge. Most machining is performed on machines such as lathes, mills, drills, and grinders.
Metal embossing is a process that creates raised or recessed designs on metal sheets. It uses male and female dies to press the metal with force. This forms shapes like logos, textures, or warning signs without cutting or removing material. Embossing enhances both appearance and surface grip and can be used for decorative or functional purposes.
Step turning is a turning method that creates two or more distinct diameters on a single round workpiece. It uses a lathe to cut along the axis at fixed points, removing material in steps.
What makes step turning unique is the sharp 90° shoulder between each diameter. This clean transition is the “step” that defines the process.
Press brake coining is a metal bending process that shapes sheet metal using very high pressure. The punch presses deeply into the metal, forcing it entirely into the die cavity. Unlike air bending, where the metal only partially contacts the tools, coining creates complete contact between the punch, metal, and die surface.
Nitrogen laser cutting uses high-pressure nitrogen gas to blow away molten material while preventing oxidation. This results in smooth, burr-free edges with no discoloration. It’s ideal for cutting stainless steel, aluminum, and other metals where appearance and precision matter. Unlike oxygen-assisted cuts, it produces cleaner finishes and helps prevent the need for secondary treatments.
Sheet metal setback is the distance from the bend’s apex to the start of the flange. It includes part of the bend radius and material thickness. This measurement helps define the amount of material used in the bend.
To make a plastic prototype, you can use several methods like 3D printing, CNC machining, or vacuum casting. Choose the process based on the part’s shape, quantity, and timeline. Start with a CAD model, select a material that matches your end-use needs, and work with a supplier or in-house tools to produce and refine the part.
Metal grooving removes material from a metal surface to create a recessed channel. These grooves can help with bending, joining, sealing, or guiding parts during assembly.
Grooves can be broad or narrow. They can be shallow or deep. Some are cut in a straight line. Others follow a curved or circular path. The shape depends on the job’s needs.
