Silica sand is a more commonly heard description of sand than is washed sand. That''s because silica sand is one of the most abundant sands in the world, whereas sand that is washed, or washed sand, refers to a level to which sand is processed.
As a result, the build volume of Binder Jetting machines are amongst the largest compared to all 3D technologies (up to 2200 x 1200 x 600 mm). These large machines are generally used to produce sand casting molds.
With its 3D technology, voxeljet delivered the sand core for the turbine rotor, which was produced as a single piece in just a few days. The power supply could therefore be secured very economically in a short period of time, due to voxeljet''s innovative 3D technology.
In 1974, the United States was poised to adopt a ban on silica sand for abrasive blasting on the recommendation of the National Institute for Occupational Safety and Health (NIOSH), but as discussed in our article on the Silica Rule, political forces hampered adoption, and wet abrasive blasting technology failed to find a foothold in North America.
A core is a device used in casting and moulding processes to produce internal cavities and reentrant angles (an interior angle that is greater than 180°). The core is normally a disposable item that is destroyed to get it out of the piece. They are most commonly used in sand casting, but are also used in die casting and injection moulding.. For example, cores define multiple passages inside ...
The VX4000 is the world''s biggest 3D system for sand molds. With a total jobbox size of 4 metres in length, 2 metres in width and one metre in height, this system can produce large individual molds as well as numerous small series components. A combination of the two is also possible quickly, economically and flexibly.
we have invested into HHS sand technology to provide a unique prototype solution. HHS systems (High Heat Strength), a phenol based binder with a silica/synthetic blended sand this combination produces a core with up to 250% higher hot strength compared to printed furan technology. This makes the cores suitable for the casting of both ...
There are many 3D technologies available, and each technology has its strength and weakness. The 3D of sand moulds, by binder jetting technology for rapid casting, plays a vital role in providing a better value for the more than 5000 years old casting industry by producing quality and economic sand moulds.
