Incomplete plastic molding is a common problem, but it is also easier to solve. When it can not be solved by technological means, it can be improved from the perspective of mold design and manufacturing, which can generally be solved.—-carrier tape in China factory

1、 Equipment:

(1) The plasticizing capacity of the injection molding machine is small. When the product quality exceeds the actual maximum injection quality of the injection molding machine, it is obvious that the feed quantity cannot make ends meet. If the product quality is close to the actual injection quality of the injection molding machine, there is a problem of insufficient plasticization, and the heating time of the material in the barrel is insufficient. As a result, the appropriate melt can not be provided to the mold in time. In this case, only the capacity can be replaced Large injection molding machine can solve the problem. Some plastics such as nylon (especially nylon 66) have narrow melting range and large specific heat. An injection molding machine with large plasticizing capacity is needed to ensure the supply of materials.—carrier tape in China factory

(2) The temperature displayed by the thermometer is untrue, which causes the material temperature to be too low. This is due to the failure of temperature control devices such as thermocouples and their lines or temperature difference millivoltmeters, or the aging or burning of electric heating rings far away from the temperature measuring points, heating failure, which has not been found or repaired and replaced in time.—carrier tape in China factory
