Investment Casting Parts With Electro Polishing and Machining for Valves “Handle Plate”

Investment casting which is also known as lost wax casting is a method used for making of precision casting complex near-net shape details using replication of wax patterns. The basic casting principle is to pour and fill molten metal into a disposable ceramic mold. Then, the molten metal adapts to the shape of the mold and forms the final products.

The process is suitable for repeatable production of net shape components from a variety of different metals and high-performance alloy. Also, this technique has been around for thousands of years, as far as the bronze age. Even though it sounds like an old technique, but the research ad development of investment casting is still going up to this day. Even today, more advanced waxes, refractory materials, and specialist alloys are used for making patterns. Therefore investment casting is one of the longest-running advanced metal-shaping technology in our human history

Electropolishing or also known as electrochemical polishing, anodic polishing, or electrolytic polishing is really useful for polishing and deburring parts that are have complex geometries or fragile. Electropolishing is an electrochemical finishing process that removes a thin layer of material from a metal part, typically stainless steel or similar alloys. This process leaves a smooth, shiny, and ultra-clean surface finish.


Who Use Electropolishing?


In the past since the 1950s, scientists have commercially used the combination of chemicals and electricity to improve the surface finish of metals. Below is a wide variety of industries that use electropolishing :

  • Surgeons and dentists use electropolishing to keep their tools clean and functioning well.
  • Food, beverage, and pharmaceutical processors benefit from the sterilizing features of electropolishing.
  • Appliance manufacturers use electropolishing in appliances like refrigerators and washing machines to make parts last longer and look better.
  • Aerospace manufacturers use electropolishing on flight-critical parts to reduce friction and ensure top performance.
  • Semiconductor manufacturers use electropolishing with fragile, irregularly-shaped products.
  • Automakers and the racing industry electropolish gears and fuel lines to reduce friction, boost performance and ensure the long life of parts.

Examples of metal parts that are commonly electropolished : Piping and tubing, Fasteners, Springs, Wire racks, Blades, etc.
