The weld marks are an important factor affecting the quality of plastic parts. The research found that: under the same process conditions, the strength of the weld line area is only 10-92% of the original material, which seriously affects the normal use of \uc0ac\ucd9c \uae08\ud615<\/a>ed products.<\/strong><\/p>\n

Avoiding these and other injection molding defects is all about using the right mold manufacturer and having a part manufacturer that has the right quality assurance to catch these defects and troubleshoot them.<\/p>\n

Injection pressure is an important factor in the filling and molding of plastic melt. Its role is to overcome the resistance of plastic melt when it flows in the barrel, nozzle, pouring system, and cavity, to give the plastic melt sufficient filling speed, and to be able to compact the melt to ensure the quality of injection molded products.<\/p>\n
