35mm White Plastic Injection Molded Products Waterproof for Antenna
Fittings
High precise white plastic injection molding support part with
individual design for communication antenna , it is like “ L “
shape and a round section is placed short end with a threaded hole
, a bending wing on each side .Longer bottom to support other
pieces and secure them from sockets in side of bottom .
Plastic injection molding support part is made from nylon PA 66 and
white color chosen . it is with good performances
Low friction and good self-lubricant for a long service
Wide working temperature from -30℃ to 150℃ for the most areas with
different climate .
Material
Plastic injection molded support is manufactured from nylon that is
the best application in engineering plastics .

Additional materials for plastic injection molding parts
In addition to PA , we provide ABS ,PP , PE ,PMMA and POM etc
materials for more plastic injection molding parts , these
materials with different features and are used for different
conditions , you can make a suitable choice according to your
applications .
| Material | Mechanical Property | Chemical Performance | Fire Resistance | Popular Application |
| ABS | Good comprehensive mechanical performances , wear resistant and
impact resistance | Corrosion resistance and stable chemical performance | Easy to be burned | Life items , toys ,electronics , sport items and furtures etc |
| PMMA | High mechanical performance and tensile strength , and resistance
to impact | Corrosion resistance and stable chemical performance | Easy to be burned | Mainly used to items that request transparency like light housing ,
wall board . Medical devices etc |
| PS | Usual tensile strneth , hard material , but weak on resistance to
impact | Stalbe chemical performance and corrosion resistance | Easy to be burned | Daily ornament , heat insulator for buliding |
| PP | Wear resistant , hard surface and high tensile strnegth , not easy
to be broken | stable on chemical performances | Easy to be burned | Various pipes , packages , parts for heat resitance etc . |
| POM | Hard surface , high tensile strength and not easy to be deformed ,
wear resistance and self lubricant | Resistance to oils but not for acid and alkali and moisture | Easy to be burned | valve , gear . Shaft . Pipes and switch housing etc . |
