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.
