High Tensile Plastic Injection Molding Products 100mm PMMA Holder Bar Parts
High tensile strength plastic injection molded holder bar parts are made of PMMA that are a quite good choice for electric communication device
With long service 5～8 years and keep color well .
Suitable deigns for easy operation
Resistant damp and water proof
Up to 92% light transmittance
Quite light weight only half to glass
Plastic holder bar injection molded part are made up of 12 square sockets and two small pin holes and a fixing pin at one end , half circle socket and a rectangle socket in the middle for supporting working piece .
