Applications:
A:Polycrystalline silicon reduction furnace is widely used in the
production of new energy materials, such as solar Photovoltaic,
semiconductor and microwave devices. It is designed with energy
efficiency, safety, environmental protection and automation in
mind.
B:Low pressure casting is a technology that uses low pressure to
form solid objects from molten metal. It has become an important
technology in the automotive industry due to its high efficiency
and precision. It can be used to make complex shapes with high
accuracy, and can also minimize scrap rate.
C:Papermaking is an ancient craft that involves transforming wood
pulp into a sheet of paper. Today, modern papermaking takes
advantage of advanced manufacturing techniques as well as modern
technology to produce a wide variety of paper products.
D:Bearings are mechanical parts used to reduce friction between two
moving objects. They are commonly used in motorized machines,
bicycles, cars, and even toys. Today, bearings are made from a wide
range of materials, including steel, rubber, plastic, and ceramic.
