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.
Galvanized steel stamping is a process that shapes galvanized steel sheets into custom parts. Before stamping, the steel is coated with a thin layer of zinc, which forms a barrier that prevents rust and surface damage. The stamping process uses dies and presses to cut, bend, or create the steel into specific shapes.
Turnkey manufacturing is an end-to-end service. The turnkey approach means the customer hands over a project to a manufacturer who manages everything. The provider oversees product design, prototyping, material sourcing, production, assembly, testing, and packaging. The client receives a final product that is ready for use or sale.
OEM stands for Original Equipment Manufacturer, and ODM means Original Design Manufacturer. OEM focuses on producing items based on a buyer’s design. ODM, on the other hand, develops products from its designs and sells them under another company’s brand. Both approaches help businesses bring ideas to market, but differ in control, cost, and flexibility.
Offset machining is making small changes to the tool’s position in a CNC machine to improve how a part is made. These changes, or “offsets,” adjust the path or depth of the cutting tool during the machining process. They are applied through the machine’s control system, without changing the original G-code program.
Subcontract machining is when a company outsources part of its manufacturing work to an external machine shop. These shops focus on cutting, shaping, and finishing metal or plastic parts to precise specifications.
