Precision casting is one of the methods of smelting. According to the demand of goods or stop hot and cold processing. Precision casting is a special smelting method which is absolutely conservative in smelting process. It can get absolutely accurate shape and high smelting precision.

It is more general to take the lead in making (or perhaps leaving no last at all) the last according to the request of the goods; to cast the wax; to lose the original mould; Is the wax mold repeated coating and sand sequence, softening shell and boring; The external wax mold is then dissolved for dewaxing and losing the cavity; Roasting shell to lose the residual strength and air leakage function; Non-metallic data required for pouring; Unhulled sand, thus losing high - precision waste products.

In the past, due to the economic recession, precision casting parts import hit a wall, international demand weakness.At present, the casting market resources are very unlimited. In the process of grabbing the market resources of the department, some enterprises with high quality and low profit will win out;All scope is small, capital is sufficient, and goods quality and profit do not have the enterprise of cooperative force can stop production or half stop production, if economic and financial crisis time is a little longer, this agency enterprise can open only.In 2007 and the first half of 2008, the high price of investment casting facilities information has led to the opening of a number of enterprises with poor operation of investment casting facilities. The current economic and financial crisis will stop the reshuffle of enterprises with investment casting facilities in China.According to this plan, the secondary data profit per ton of castings increased by 2000 yuan, if you think about the ferroalloy price increase factor, the profit of castings decreased more;Simultaneous, the coke price rise also caused the rise in smelting profits.Subject to a sharp decline in the prices of casting facilities, the one-sided price increase of casting goods is a certain trend.A certain account is not only casting consumer enterprises clear, casting users will also be calculated, because the price increase trend of casting goods can not be prevented, the key is how to use our investment casting facilities enterprises smart with users to stop the game, is a new round of price talks to achieve a win-win situation.According to the plan of the month with the highest original material price in 2008, the market price of cast iron without tax has been reduced to 2,800 yuan /t and beyond, which is about 40% of the price.Scrap steel down to 2000 yuan /t inside and outside, down about 53%;The coke of the investment casting facility dropped to 2400 yuan /t inside and outside, down about 38%.From the above introduction is not good to see, whether it is fine smelting facilities consumption industry or fine casting consumption enterprises, will face a serious challenge, haixin machine company will be active attitude, chaos for change, single-minded for the vast user needs more childlike services!

Survival of the fittest can be a bad thing from another standpoint.

1, the handling of the shell must be careless, to prevent damage to the shell.

2, dewaxing, dewaxing kettle machine door must be closed tightly, lest the heat dissipation, there is no need to touch or scratch the door of the furnace sealing aggregate, if there are scars should be immediately changed.

3, the loading of repeated measures the faster the better, if early time will form the shell early heat stroke, because wax than shell heat shrinkage, easy to shape shell protection.

4. Timely clearing dewaxing filter net and trajectory to prevent blockage.When extricating wax kettle machine door, absolutely did not have to be able to put the foot is visitors, to prevent the outflow of hot water burns.

5. Wear gloves when operating.
