The process of sheet metal fabrication has progressed and developed over time due to the high demand and broadening uses across multiple industries. Now, there are many ways to fabricate sheet metal. With so many different processes, sheet metal fabrication has really become a form of art. Some of the processes are as follows and the links below are the services we provide:

• Shear

• Bend

• Coin

• Laser cut

• Punch

• Forming

The sheet metal fabrication industry has grown rapidly world-wide due to the constant product development within these industries. As a result, many products contain all kinds of metal componentry that most people do not realize. Below is a list of the types of parts that Yiphang manufactures:

• Chassis

• Enclosures

• Brackets

• Drawers

• Cabinets

Material Info & Types

• A36 is a very common mild steel. It is much easier to form than CRS 1018, but more difficult to machine.
• A653 Galvanized is a steel that contains zinc coating for protection against corrosion.
• Stainless Steel (CRES) is an alloy based on chromium and steel and is categorized by its resistance to corrosion. The gauge thickness is the same as regular steel. Stainless is much harder than regular steel and is not easy to work with in some respects. Our lasers love it and have no problem cutting it. However, it is difficult to punch, and can be difficult to weld. Below gives a description of the different stainless types:
  • CRES 304 is the most widely used multipurpose stainless steel which is easy to weld and form.
  • CRES 301 is commonly used for fasteners and springs which offers better wear resistance and fatigue than 304. This type has good weldability.
  • CRES 316 has great corrosion resistance compared to 304, so it is best used for chemical processing applications. This type has good weldability and temperature resistance.
  • CRES 303 is a good material to machine, which makes it best used to create screw machine products. It is also good for corrosion resistance and temperature.
  • CRES 410 is commonly used for fasteners, machine parts, and shafts since it can be heat treated for extra hardness and extra wear resistance.
• Aluminum are mixtures of aluminum with other metals, often with copper, zinc, manganese, silicon, or magnesium. There are too many alloys of aluminum to list. The number after the 4 digit code is the tensile strength or temper of the alloy that ranges from T0 to T6. T0 is soft, and T6 is full hard. VIP uses, 5052-H32, 6061-T6, 6061-T4, 2024-T0 for most of our parts. Below gives a description of the different series of aluminum:
  • 5052-H32 is the most common alloy we use. It has excellent corrosion resistance, easy to form, and easier to weld. It is not heat treatable and nonmagnetic.
  • 6061-T6 is a multipurpose aluminum with good strength, corrosion resistance, and machinability. It is heat treatable but nonmagnetic.
  • 2024 has great strength compared to mild steel, but weighs a lot less and has less corrosion resistance than 7075. It is heat treatable but nonmagnetic.
  • 7075 is a very strong and lightweight aluminum with better corrosion resistance than 2024. It is commonly used for aircraft parts which is where it gets its common name "aircraft aluminum."
