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 .
