On November 23, 2010, the much-anticipated Bauma China 2010 Fifth China International Construction Machinery, Building Materials Machinery, Engineering Vehicles and Equipment Expo opened at the Shanghai New International Expo Center.
Shell casting puts resin coated sand on the preheated metal template with mould ,makes the resin melt and form a layer of shell.It achieves the desired moisture and rigidity after melting,drying and hardening.
The shell mold casting is applied to the automobile,train,shipbuilding,electronic and semiconductor industries.The material can choose a variety of copper alloys,aluminum alloy,zinc alloy,ductile iron,gray iron,stainless steel and carbon steel.
Shell casting is a metal casting process similar to sand casting,in that molten metal is poured into an expendable mold.However,in shell mold casting,the mold is a thin-walled shell created from applying a sand-resin mixture aroud a pattern.This casting process requires the use of a metal pattern,sand-resin mixture,dump box and molten metal.
The shell mold casting process is composed of following steps:
A two-piece metal pattern is set up in the shape of the desired part,typically from iron or steel.Other materials are also can be used,such as aluminum for low volume production or graphite for casting reactive materials.
After the molten metal is cooled,the mold can be broken and the castings can be removed.Trimming and cleaning processes should removed any excess metal from the feed system and any sand from the mold.

Taking advantage of the tremendous international influence of this professional exhibition, Xingma Motors and Hualing Heavy Trucks made their debut at the BMW Exhibition with state-of-the-art engineering machinery products. This is the result of the Xingma Group following the Beijing Auto Show and the Hannover Commercial Vehicle Show in 2010. Since participating in an international exhibition for the third time, on the stand of the Xingma Group, there have been many star products such as concrete mixer trucks, concrete pump trucks, and star Kama tractors, as well as new mining dump trucks independently developed by Xingma. With the car crane, also debuted at the Shanghai BMW Exhibition.
According to reports, at this year's Shanghai Baoma Exhibition, the most representative of the Xingma Group is the Xingkama heavy truck and mine dump truck. It is understood that the exhibited Xing Kaima Heavy Trucks adopts a new safety and lightweight design concept in the design of the vehicle. The cab adopts a four-point suspension structure, airbag damping, large storage room, exquisite workmanship, and excellent interior design. These fully illustrate the representativeness of Starkaima's high-end heavy trucks. It is reported that StarKama Heavy Trucks has now obtained the world's most stringent EU certification, which also shows that the quality of StarKama has gained worldwide recognition.
In addition, at the BMW Exhibition, the 6×4 dump trucks exhibited by Hualing are also quite interesting. Eaton’s double countershaft transmissions, the ArvinMeritor Engineering Bridge, and the ZF hydraulic steering gear are enough to guarantee the quality of the car. It is reported that this car adopts advanced finite element grading software design; large cross-section, high-intensity, wide-body car driving structure; a wide span suspension system designed specifically for heavy-duty conditions to improve vehicle operation, turning The stability of the ramp, unloading, the use of three-dimensional digital design cab, the popular European up and down integrated air conditioning system, cooling capacity of 4500 kcal, to meet the harsh conditions of the field requirements.
It is understood that bauma is a brand construction machinery exhibition that has been refined for more than 50 years in Europe, and bauma China is an extension of the brand in the Asian market. From 2002 to now, bauma China, which is held once every two years, provides international buyers with excellent purchasing opportunities and creates ample space for Chinese companies to show themselves. As the largest and highest specification construction machinery trade fair held in China, Shanghai Baoma Exhibition is not only a business and trade center of the international construction machinery industry, but also an important platform for practitioners from all over the world to gather information and expand contacts. As a well-known domestic enterprise, Xingma Automobile has participated in Shanghai Baoma Exhibition for three consecutive years.
