What is precision injection molding
Precision injection molding is mainly different from the "conventional injection molding", with the polymer materials and microelectronics technology, high-speed development of highly integrated electronic circuits, making industrial equipment parts for the progressive development of high performance, high precision, Miniaturization and miniaturization. This precision plastic parts meet the requirements of high precision, and have good mechanical, mechanical properties and dimensional stability, etc., in the mechanical, electronic, communications, automotive and other industries to replace some of the high precision metal parts and has been widely used.
From the definition of precision injection molding, we can see, precision plastic parts of the dimensional tolerance range is very narrow. In fact, the plastic molding industry recognized, when the plastic parts of the size tolerance of 0.1mm or less, or workpiece size tolerance of 0.1mm or less, can be called precision molding, parts of the dimensional tolerance to microns Level, can be called ultra-precision injection molding.
Relative precision injection molding, the general injection molding of the workpiece size tolerance is usually 0.1mm or more, parts of the dimensional tolerance range is relatively wide, and with the workpiece size or weight increases, the size of the workpiece tolerance will Has increased. It is worth mentioning that, due to the nature of the material itself and processing methods are different, not the plastic parts of precision and accuracy of metal parts equated. Plastic products, the highest accuracy level is three precision, the dimensional tolerances up to 0.001 mm below the size of metal parts can be divided into 14, the processing accuracy of nine points.
