What are the performance advantages of SMC fiberglass composite material gas meter combination metering box body shell? Gas meter combination metering box shell is suitable for a variety of pipe diameters and gas meters, it is easy to install and manage, meter read and maintain. Many gas meters intergrated into one box, gas meter combination metering box shell could be produced by SMC composite material moulding process. SMC is the shortage for Sheet moulding compound. SMC is the abbreviation for Sheet Moulding Compound which main consists of GF (special yarn), UP (Unsaturated Polyester Resin), low profile additives, MD (filler) and various additives. It firstly appeared in Europe in the early 1960s, and around 1965 the process successively developed in the United States and Japan. China had introduced advanced SMC production lines and production processes in the late 1980s. After more than half a century of development, SMC has been widely used and developed rapidly especially in automotive, construction, electrical, marine, anti-corrosion containers and other aspects all around the world. Based to its excellent design, craftsmanship, corrosion resistance, good stability and so on. SMC has gradually replaced the metal materials and traditional plastics, and become the new favourite of the industry in some aspects.
SMC has the following advantages：
1. Eco-friendly and green
SMC is a new type of Eco-materials without halogen and harmful substances, which would meet the needs of green development in the future.
2. Chemical resistance
SMC has good resistance to acid, dilute alkali, salt,organic solvents, seawater and other corrosive properties, while the metal material is not acid-resistant and corrode easily.
3. Lightweight and high strength
Specific strength and specific modulus are one of the indicators of measuring the carrying capacity of materials, the specific modulus of SMC is comparable to steel, however the specific modulus could quadruple to steel.
4. Flame resistance
SMC is class B non-combustible tested by the national authority with fireproof and flame retardant.
5. Heat resistance
SMC have the ability to maintain its physical properties in harsh, high-temperature environments, with operating temperature ranging from 60°to 150°,and heat deflection is over 280°.
6. Low thermal conductivity and expansion coefficient
The thermal stress generated in difference temperature is much lower than metal with good thermal insulation performance.
7. Aging resistance SMC has aging resistance.
After the anti-aging performance test, its maximum surface aging thickness is less than 50μm for 20 years.
8. Long service time
SMC has a proven history of service for 30 years life at least.
9. Production efficiency
With short moulding cycle time, SMC is easy to mechanize and automate.
SMC moulding process is one of the more productive FRP composite moulding processes with many advantages:
1. High efficiency and appropriate for producing abundantly.
2. Closed moulding applications with polystyrene and glass fibre dispersion and good working environment.
3. Simple moulding process, appropriate for mechanization and automation, it could also be molded even without skilled workers.
4. Can form large products.
SMC molded products have the characteristics of accurate size, smooth surface, good appearance and size repeatability of products, complex structure can also be formed once, and secondary processing would not damage products, but the shortcomings of SMC composite molding process are also available: the use of press, metal mold, heating device, etc., and the initial equipment investment is large.
