Casting Patterns and Patternmaking Metal Casting Blog

Casting Patterns And Patternmaking Metal Casting Blog

Casting is the process of pouring liquid metal into a mold, where it cools and solidifies. The casting process can produce everything from art pieces to engine parts. The shape is determined by the mold cavity, but something needs to shape the moldthats where the pattern comes in. Patterns are a model for the object to be cast.

Filter Sand . The filter sand used in rapid sand filters is manufactured specifically for the purpose of water filtration. Most rapid sand filters contain 24-30 inches of sand, but some newer filters are deeper. The sand used is generally 0.4 to 0.6 mm in diameter. This is larger than the sand used in slow rate filtration.

An Overview Of Heat Treatment Methods Their Benefits

Feb 13, 2020 There are various reasons for carrying out heat treating. Some procedures make the metal soft, while others increase hardness. They may also affect the electrical and heat conductivity of these materials. Some heat treatment methods relieve stresses induced in earlier cold working processes. Others develop desirable chemical properties to metals.

Pump foundation. Proper pump foundation reduces vibration levels, which in turn leads to a significant increase in Mean Time Between Failures (MTBF), extended lifetime of mechanical seals and bearings and consequently reduced total life cycle cost.. Pumps have to be properly secured to their base plates, which in turn have to be well-bonded to the underlying foundation.
