    Incorrect injection mold temperature

    1.The influence of mold temperature on appearance: Firstly, the mold temperature is too low, which will reduce the melt fluidity and may cause underinjection. Mold temperature affects plastic crystallinity, for ABS, mold temperature is too low, the product finish is low. Compared with fillers, plastics migrate more easily to the surface when the temperature is high. So when the temperature of the injection mold is high, the plastic composition is closer to the surface of the injection mold, the filling will be better, and the brightness and luster will be higher. But the injection mold temperature can not be too…

    How to clean a hot clog in the head of an FDM type 3D printer

    Residues are inevitable for FDM 3D printers for several reasons: small amounts of plastic are scorched by the overheated hot end, causing them to accumulate inside the nozzle; contamination from foreign bodies inside the wire after it has been produced; dust that has fallen on the surface of the wire reel is scorched and accumulates; trash is accidentally discarded into the hot end, etc. As a result FDM 3D printers often suffer from under-extrusion: for no apparent reason, but the extruder is unable to extrude enough material. If the extruder is pushing the wire at this time and the reel…

    3D printing changes the way manufacturing costs are calculated

    In the traditional sense, the more complex the shape of the goods, the higher the manufacturing cost, which is undoubtedly a large expenditure for enterprises. However, with the widespread application of 3D printers, the complexity of items will no longer be directly proportional to the cost. No matter how complex the shape of the manufactured goods is, the 3D printer can be easily solved without increasing the cost, because there is no relationship between 3D printing complex goods and printing a simple goods. The cost of 3D printing is only calculated according to the material cost, time cost and machine…
