"Gravity Die Casting. A permanent mould casting process, where the molten metal is poured from a vessle of ladle into the mould, and cavity fills with no force other than gravity, in a similar manner to the production of sand castings, although filling cn be controlled by tilting the die."
Sometimes referred to as Permanent Mould, GDC is a repeatable casting process used for non-ferrous alloy parts, typically aluminium, Zinc and Copper Base alloys.
The process differs from HPDC in that Gravity- rather than high pressure- is used to fill the mould with the liquid alloy.
GDC is suited to medium to high volumes products and typically parts are of a heavier sections than HPDC, but thinner sections than sand casting.
There are three key stages in the process.

Someone used tough to move forward to describe China's home furnishing industry in 2013, but used pain and happiness to describe the Chinese lighting industry. According to statistics, under the premise of difficult environment in the building materials and home furnishing industry, the lighting companies have achieved a performance increase of 100 against the market.
And in the new 2014, will the lighting industry continue this brilliant performance? What new trends will the lighting industry usher in? Xiaobian intends to analyze and discuss the market environment, consumption upgrade, channel transformation, product design, service concept and other aspects, and ask for the direction of the lighting industry in 2014.
Challenges and Opportunities Brought by Channel Sinking The Third Plenary Session of the 18th Central Committee emphasized the construction of urban-rural integration. Under the general trend of urbanization of agricultural population, consumption is also facing an upgrade, and lamps also have good access to thousands of peasant families. opportunity. The key reform direction decided by the Central Urbanization Conference is to vigorously develop small towns, expand small and medium-sized cities, and limit megacities. Lighting enterprises will face a huge rural market. With the acceleration of the urban-rural integration process and the increase in farmers' incomes, the rural market will become a very promising cake.
Intelligent and traditional campaign lighting in the lighting industry is not a new topic in the industry. Intelligent lighting has been frequently seen in the industry a few years ago, but at the same time, smart lighting mostly stays at the stage of high level. Really popular among consumers.
The biggest advantage of traditional personalized lighting fixtures is that they can meet their specific needs according to different groups of people. In the process of R&D, intelligent luminaires will inevitably require a lot of research funding. This expenditure will ultimately be borne by consumers of intelligent lighting. As a result, intelligent lighting can only take high-end consumption routes in the early stage of implementation. Difficult to spread in the mid-end market.
Spring of aging and environmental protection In 2013, China ushered in the first peak of the elderly population growth, with an elderly population reaching 202 million and an aging level of 14.8. According to industry insiders, with the acceleration of the aging of the social population, the household industry also In the search for opportunities for aging, in product design, more attention will be paid to the needs of the elderly.
At the same time, with the frequent occurrence of smoggy weather in China's major provinces, environmental protection has become a hot spot for consumers to pay attention to. Severe environmental pollution is a heavy price brought about by the economic development of more than 30 years. Therefore, the future energy conservation and environmental protection industry is definitely the development direction, as is the lighting products. Personalized lighting is the core part of the room. Obviously, whether it is environmentally friendly is of great significance to consumers. The health, environmental protection and green road will be the mainstay of the lighting industry in the future. More and more consumers will incorporate environmental protection into the reference of product selection.
The standard implementation eliminates the chaos in the lighting market. The personalized lighting industry has completed the process of forming a home life concept from scratch, from development to development. Such rapid development, on the one hand, makes the industry more optimistic about the prospects of personalized lighting; on the other hand, the rapid development pace, the individual standards and specifications of the personalized lighting industry failed to keep up, resulting in customization The lighting industry is chaotic.
Nowadays, the shift from selling products to selling services has become a common understanding of many lighting companies. In today's lighting industry with individualization as the mainstream, from the choice of samples to styles, to product wattages, installation and distribution, etc., all are linked to the services of the merchants. The brand image has the most direct impact. Jiuzheng Building Materials Network interprets 2014 and looks forward to the future of the industry. Under the influence of many favorable policies, driven by channel reforms, in the promotion of service concept upgrading, China's lighting industry will inevitably climb a higher peak to further Improve the mature attitude and popularize more and more Chinese families!
