Plating Equipment: Barrel, Rack and Basket
PRICEWalgren is a world leader in the design, building and commissioning of high-performance plating lines for decorative and functional applications.
We also supply advanced automated barrel technology that saves labor and time. PRICEWalgren equipment is preferred worldwide for these processes, and more:
- Zinc Plating prevents corrosion by creating a physical barrier and acting as a sacrificial anode when the barrier is breached. Commerical zinc deposits are typically 0.0001″ – 0.0003″. Properties include a high coefficient of friction, moderate abrasion resistance, and poor impact resistance.
- Copper Plating
- Nickel Plating
- Chrome Plating
- Brass Plating
- POP (Plating On Plastics) process includes etching the plastic to create a hydrophilic surface with good ahesion potential, activating the surface to generate catalytic sites on the non-conducting plastic, deposition of a this film of electroless nickel or electroless copper, and electroplating, which is generally nickel, which is generally nickel, with or without a topcoat of gold or silver.
- Zinc-Nickel Plating is an environmentally preferable alternative to cadmium plating for steel, cast iron, malleable iron, copper, and brass from corrosion. Zinc-nickel is also well suited to galvanic interaction applications.
- Zinc Alloy Plating is a type of electrogalvanizing. Alloying zinc with cobalt or nickel at 1% or less improves the zinc layer’s ability to develop a chromate film. Zinc alloy plated parts are treated with conversion coatings and top coated to enhance corrosion and wear resistance and control coefficient of friction.
- Electroless Nickel Plating deposits a layer of nickel-phosphorus or nickel-boron alloy on a workpiece. The process’s reducing agent (NaPO2H2•H2O) reacts with metal ions to deposit metal. Tailoring the percentage of phosphorus (generally 2014) determines metallurgical properties.
- Hard Chrome Plating reduces friction, enhances abrasion and wear-resistance, minimizes galling and seizing and imparts oxidation resistance. It is also very hard: 65 to 69 HRC.
- Cadmium Plating provides exceiptional protection for ships and aircraft from atmospheric corrosion. The coating thickness usually varies from 15 to 25 jam. Complex cadmium salts are used to coat parts with complex geometries.
- Copper-Nickel-Chrome Plating is an elite process that ensures the longest service life for chromed parts. Parts are first plated with copper, a non-ferrous material that fills minor imperfections. Nickel and chrome plating follow.
- Tin Plating protects both ferrous and non-ferrous substrates. In the electronics industry, it preserves solderability by preventing base metal oxidation.
- Nickel Plating involves a combination of heat treating, cleaning, masking, pickling, and etching before work pieces are submerged in an electrolyte solution, becoming the cathode. A nickel anode is dissolved in the electrolyte as nickel ions; these ions deposit on the cathode.
- Electropolishing is an electrochemical process used to polish, passivate, and deburr metal. It improves the surface by leveling micro-peaks and valleys, and can be used in place of abrasive finishing. It is the preferred method for passivating stainless steels. Electropolishing yields a substrate that is easy to sterilize, and is ideal for areas inaccessible by other polishing methods.
