The best way to design sheet metal parts for laser cutting is to keep shapes simple, add proper spacing between features, and match thickness to the design needs. Corners should have radii instead of sharp edges. Holes should be large enough to cut cleanly. Designs should also consider how the part will be bent or welded later.
Flatness in GD&T shows how close a surface is to being perfectly even across all points. It controls how much a surface can vary in height. Flatness sets a tolerance zone made of two parallel planes to do this. The surface of the part must stay between these two planes. This prevents bends, waves, or bumps that could cause trouble during assembly.
Galvanized steel is stronger and cheaper, making it suitable for heavy-duty applications. Aluminum is lighter, resists rust naturally, and is better for projects where weight matters. Both metals perform well in different environments, but the choice depends on specific needs such as strength, weight, and corrosion resistance.
A Medical Device Original Equipment Manufacturer (OEM) is a company that designs and makes medical devices for other businesses. They do not sell products under their own brand. Instead, they handle the technical and production work needed to deliver a product ready for the market. OEMs can support early-stage development, prototype testing, regulatory compliance, and large-scale manufacturing.
Value added assembly goes beyond simply putting parts together. It is a process that combines several steps into one service. Instead of sending parts to different vendors for sub-assembly, wiring, fastening, or packaging, one provider handles everything under the same roof. This reduces handoffs and keeps production flowing smoothly.
Lapping is a process where two surfaces are rubbed together with an abrasive material in between. The abrasive can come as powders, pastes, or slurries. It removes tiny amounts of material from the workpiece. Lapping aims to create smooth surfaces, fix minor shape errors, and achieve precise dimensions.
Fits are an essential part of mechanical assemblies. They describe how two parts connect and work together, most often a hole and a shaft. The fit decides whether the parts move freely, lock tightly, or stay somewhere in between.
Vapor polishing is a finishing process that uses chemical vapors to smooth the surface of a plastic part. The process starts by placing the part inside a sealed chamber. A chemical like methylene chloride is heated until it becomes a vapor. When this vapor contacts the plastic, it slightly melts and reshapes the outer layer. This reshaping fills in rough spots, scratches, and minor marks.
Bright dip anodizing is a chemical finishing process. First, the part is cleaned and degreased. Then it goes into a chemical bath that makes the metal smooth and shiny. After that, the part is anodized to form a protective oxide layer. Finally, this layer is sealed to keep the surface resistant to corrosion and maintain its shine.
PVDF coating is a high-performance protective layer made from polyvinylidene fluoride resin. It is known for excellent weather resistance, chemical resistance, and color retention. It protects surfaces against corrosion, UV rays, and abrasion.
Honing uses abrasive stones to remove small amounts of material and improve surface finish, while lapping relies on abrasive slurry between surfaces for high precision. Honing is better for cylindrical parts with tight tolerances. Lapping is better for flat surfaces or when extreme accuracy is needed. Both processes reduce friction, improve durability, and support high-performance parts.
Contract assembly means working with an outside partner to assemble parts, subassemblies, or finished products. The client can supply the components or ask the provider to source them. The provider then follows the given instructions to assemble the product. This method helps companies control costs, lower risks, and focus on their primary business.
Aluminum rolling is pressing aluminum ingots or slabs into thinner shapes using rotating rollers. Depending on the rolling method, the aluminum usually starts as large blocks that are either heated or kept at room temperature. As the rollers press down, they squeeze and stretch the metal, turning it into flat sheets with accurate thickness and size.
Aluminum grades are numbered series that group alloys by their central element. Each series offers different properties. For example, the 6000 series provides good strength and weldability. The right grade balances your needs for strength, corrosion resistance, and how easy it is to machine.
Epoxy-coated aluminum is aluminum covered with a thin, even layer of epoxy resin. The resin bonds firmly to the surface, forming a tough, protective shell. This shell works as a barrier against moisture, chemicals, and wear. It also gives the surface a smooth finish, which can be clear or colored.
Geomet coating is a water-based protective layer made from zinc and aluminum flakes. It forms a thin, even film on the surface of metal parts. This layer blocks moisture, salt, and chemicals, helping to stop rust and wear. Since it does not contain heavy metals like chromium, it is safer for workers and better for the environment.
