Precision injection molding is a method demanding unparalleled accuracy in shaping plastic components. Unlike mass production, it’s reserved for cases where precise forms are crucial. These precise plastic parts are commonly used in replacing high-precision metal parts in fields like instruments, electronics, optics, and medical equipment. Due to these stringent requirements, precision injection molding relies on precise molds and machinery, making it a complex process.
The size tolerance of precision injection molds is controlled to less than 1/3 of the product size tolerance. The mold’s precision depends on factors such as the accuracy of cavity size and quantity, cavity positioning, accuracy of parting surfaces, material selection, size tolerance, and more. Factors like the thickness of the base plate, support plate, cavity walls, and runner size are crucial for precision molds. The design engineering is equally vital, with molds typically made from high-strength alloy steel.
Precision Injection Molding Process:
Every component developed in precision molding projects must be identified, as their connection is uniform. This ensures a slow, stable, and concentrated precision molding process. The uniqueness of the process for each project emphasizes the importance of mold, part design, material selection, and procedures for successful precision molding.
Precision injection molding machines must control product accuracy and repeatability. The machine should feature a rigid clamping system, part size tolerance control, molding speed, and various components like the screw, screw head, barrel, and collar, all controlled within 0.05 to 0.08mm.
Precision injection molding is a game-changer for industries requiring high-tech, detailed, and complex parts in large quantities.
