SMC/BMC Antenna Reflector

(1) High precision, high efficiency, and high gain.

The most important job of using SMC/BMC for the manufacture of antennas is to
fully exploit its features and achieve high precision in antenna design from
product design and process. Under the condition that the shrinkage ratio of the
material and the SMC / BMC molding shrinkage rate have been considered in the
mold size design, the SMC/BMC reflector surface has a smaller shape from the
original design paraboloid after molding. That is, the accuracy of the SMC/BMC
molded antenna is completely guaranteed by the accuracy of the mold. The rms
value of the SMC/BMC antenna molded integral reflection surface is 0.25 mm, and
the rms value of the single-piece reflection surface of the split antenna is
less than 0.3 mm, and the rms value of the reflective surface after assembly is
less than 0.6 mm.

(2) Corrosion resistance

Conventional antenna materials such as aluminum plates and steel plates are
made of metal materials, not as good as SMC/BMC which as a non-metal dielectric
composite material in terms of acid resistance, alkali, salt, and corrosion
resistance. The Pikington laboratory in the United States used infrared to
analyze the surface of SMC/BMCmaterials and found that its surface is covered
by additives, resin, and very fine calcium acid filler. It has good acid
resistance, water resistance and corrosion resistance. The antenna reflection
made by this material is solved the disadvantage of the traditional metal
material antenna is easy to corrode. In coastal areas, rainy, humid areas and
areas with excessive acid rain, the anti-corrosion advantages of SMC molded
antennas are particularly prominent. The SMC/BMC molded antenna samples were
placed in 130 highly corrosive chemical environments at an ambient temperature
of 50 ° C. The results showed that the test samples showed little or no
change.

(3) Long life

The average aluminum plate antenna is as small as 2-3 years in the coastal
area, and more often 4-6 years, and it will generally be damaged by salt spray
erosion and aging. The most obvious example is the cable TV (CATV) in Taiwan,
which was built earlier than the mainland. It is estimated that there are
nearly 1000 satellite TV receiving antennas on the island, all built in the
mid-1980s, all of which were aluminum plate antennas, until the early 1990s. ,
that is, has begun to replace. The service life of SMC molded antennas is
generally more than 15 years; PROMLIN's prototype SMC molded antennas in 1985
are still working normally, and they are subject to typhoons and heavy rain
every year.

(4) Strong wind resistance

Since the antenna reflection surface is designed during the molding process,
multiple longitudinal and circumferential rib structures are designed.
According to the structural strength calculation, the SMC antenna can withstand
a wind load of 45 m/s, which shows its remarkable structural rigidity and
strength.

(5) Special reflective layer technology

The reflective surface of the SMC antenna uses a metal aluminum mesh as a
reflective layer of electromagnetic waves. The aluminum mesh in the finished
antenna is evenly embedded under the surface SMC, which can reflect
electromagnetic waves and insulate the atmosphere, and plays a good protective
role.

(6) Good consistency, no deformation, easy to transport and install
Because SMC antenna adopts membrane pressure technology under high temperature
and high pressure. Its material properties and processing technology determine
the unparalleled consistency of SMC antennas with other antennas. This not only
ensures the accuracy and high gain of the antenna, but also is very easy to
install and debug. SMC, commonly known as "glass reinforced plastic", has the
characteristics of no deformation, which eliminates the adverse effects of
antenna deformation on the satellite receiving system during transportation.

SMC and BMC composite require heating rather than cooling systems. The
temperature of the mold is usually between 130 and 160. It is very important to
keep the temperature of the mold and the exhaust gas when designing the mold.
The mold is easier to fill, the product is not easy to be deformed, and the
surface is better. Commonly used heating systems are steam, oil and electric
heating rods.

Vacuum assisted systems for BMC and SMC molds: Products with Class A surfaces
are usually vacuum-assisted, and the internal cavity and vacuum insulation of
the mold are very important. The mold must have a sensor and a vacuum system to
measure the mold temperature and pressure vacuum. Production SMC and BMC
molding: must guarantee high quality, long life and economy. Aobang Technology
Co., Ltd.'s years of experience in the production of SMC and BMC molds and
proficiency in machine, mold, material and process can ensure the maximum
benefit of customers.
