 The plasma cutting process is a sheet metal fabrication process . It has become one of the most popular and widely used thermal cutting processes in industrial fabrication and manufacturing. Its ability to cut through all conductive metals with precision and speed makes it a versatile choice for many applications. However, like any process, plasma cutting has advantages and limitations. Pros of Plasma Cutting Cutting Speed One of the most significant advantages of the plasma cutting process is its very high cutting speed capability. Plasma systems can make straight cuts at over 100 inches per minute on thin gauge metal less than 1/4" thickness. This is around 2-3 times faster than processes like oxyfuel or laser cutting. The high speed is achieved because the plasma jet melts a very narrow kerf width of only 1/16" to 1/8". Plasma still maintains faster cutting speeds on thicker steel plates than other methods. Cut speeds will reach 30-40 pm on 1" mild steel with h...

Gravity casting, also known as permanent mold casting, can be ideal for manufacturing metal components for specific applications. This article will examine when gravity casting is the optimal choice over other casting methods or machining processes to meet project requirements. Critical factors like part geometry, production quantities, material options, quality needs, lead time, and cost will be analyzed. What is Gravity Casting? Gravity casting relies on the force of gravity to fill metal molds positioned below a pouring basin. Once the mold cavity is filled, the liquid metal solidifies into the desired shape. The mold remains stationary during the pouring and solidification process with no applied pressure. The critical advantage of gravity casting is its use of reusable metal molds, typically made from cast iron, steel, or aluminum alloys. It enables repeatable production of consistently dimensioned castings with good surface finish at a relatively low cost. Simple castings may onl...

 Precision casting service refers to a group of metal casting processes capable of producing dimensionally accurate metal parts with tighter tolerances and better surface finishes than conventional casting methods. The tolerance standards achieved depend on the specific casting process used. This article mainly discusses the tolerance standards of precision casting services that Neway can provide and can be achieved, including die casting, sand casting, and investment casting. Investment Casting Tolerance Standards Investment casting service is considered one of the most precise casting processes, capable of tight tolerances down to ±0.005 in (±0.13mm) or even tighter for small castings under four in2. For larger castings, the typical tolerance range is ±0.015 in (±0.38mm) or ±0.5% to ±1% of the nominal dimension. The wax pattern used in investment casting can be formed to exact dimensions, creating an accurate mold cavity in the ceramic shell. The ceramic shell withstands the fo...
