Advantages and disadvantages of aluminum sand casting
part:
Generally use wooden and aluminum mold, far cheaper than metal
mold casting mould. The price advantage is particularly prominent in small
batch and bulk production. But the production efficiency is low; Low dimension
accuracy of castings, the surface is rough.

The secretary of the Sunshine Lighting Board said that in the current field of energy-saving lamps, the upgrading of products is getting faster and faster, and the standards for environmental protection and energy conservation are getting higher and higher. Sunlight Lighting selected micro-mercury environmentally-friendly energy-saving lamps and LED energy-saving lighting products as the first refinancing project since its listing.
The LED project is also to take advantage of the company's own technology, market and channels to seize market opportunities. The micro-mercury environmental protection and energy-saving lamp industrialization project implemented this time can reduce the mercury content of a single energy-saving lamp to 0.85mg or even lower, and create a profitable development route for the company and shareholders.
Sunlight believes that for a long time, LED will coexist with energy-saving lamps and develop together. The company will use the current mainstream energy-saving lamps and LEDs of future trends to walk with two legs.
Sunlight Lighting said that it will strive to achieve 10 billion sales in 2018, and to achieve domestic and foreign market share; half of lamps and light sources; foreign brands and international cooperation.
