According to report of media, owing to the restriction of capacity, cost and other area, the PC manufactures have to apply some new materials like fiber glass on ultrabook. What's more, the inside part of ultrabook notebook's aluminum metal shell will apply plastic material to replace metal.

Ultrabook notebook of Intel applies an organic whole molding all-metal body. The CNC machine tool can only produce an organic whole molding body with three hours, which means that a machine can only produce 8 organic whole molding bodies in a whole day. Besides, because of the pollution problem in last days, Catcher Technology - the largest organic whole molding body manufacture in the world has some problems on capacity. However Catcher Technology is still supplying the goods in prior for Apple, so other PC manufactures is very hard to get the enough supply of organic whole molding body.

Ultrabook is generalized by Intel, and it is trying to challenge the Macbook Air of Apple. The goal of ultrabook is to produce a kind of notebook that is as light and thin as the macbook air, and the price should be lower than Macbook Air. However, during the imitation of Macbook Air, the manufactures of Ultrabook meet these problems, for example, the short supply of aluminum material of organic whole molding. Consequently manufactures of ultrabook try to apply new materials, such as the high density fiber glass, or apply the aluminum shell with plastic inside part.

According to the report, the shell of ultrabook notebook will divides into three parts. The high-end one applies with whole metal organic molding, the middle-end one applies new body which inside part is plastic and outside part is metal, while the low-end ones will use plastic fiber glass body. The inside of new aluminum body will apply plastic, and outside part is still using meal, the plastic and metal will adhesive by glue.

Applying with news material, the capacity will increase, and the cost of ultrabook will be low. It is reported that an organic whole molding body with whole metal will cost 40 - 80 dollars, while the news body will only cost 20 - 30 dollars. Applying with new material will help the price of ultrabook notebook to decrease.
