|Injection molded parts faults remedy|
People are keen to have an a logical, systematic approach to deal with shortcomings, and many of the actual injection of their operating strategy, compiling these strategies is most important is to ensure that all terms are clear semantics, and can be all concerned understood. To clearly describe the shortcomings of the Note, the causes have to check all possible. Its impact should also be included, when the causes are identified, you should take the necessary steps to reduce and prevent their re-appear. There are six o///'clock strategies.
1, To the disadvantage of naming. Shortcomings have different names, and therefore decided to use that name after the stop change.
2, Describes the shortcomings. Description of the shortcomings may be a possible reason. For example: "injection inadequate, that is, incomplete Note
Plastic, may be described as "mold filling pressure" or "fill the mold the plastic to try the most simple words without involving any possible reason to describe this is a useful method in this way, we in the next step to find the cause of the disadvantage of not grab any costs met.
3, Find the cause of the shortcomings, this may be a long process, because he needs to take into account the plastic injection molding machine, mold
Work process. The following are the recommended guidelines.
Plastic: Check the level or type, check the impurities, and confirm whether it meets the manufacturer///'s specifications. If the shortcomings in a few of the same manufacturer///'s batch of plastic or another supplier, the same plastic are all very similar, indicating that the plastic does not.
B, Injection molding machine: indecent injection molding machine all parts of the function, and to consider any factors that may affect the pressure, temperature, rate and time, if the disadvantage is that the intermittently, which usually implies that the injection molding machine operation error, such as a bad flu isotherms caused by temperature fluctuations, if the shortcomings in the same location of a single-mode cavity mold, which suggests that the cause of the problem out on the flute material cylinder devices, or control adjustment of the injection.
C, Mold: To determine the mold is properly installed, and at the correct temperature, and all parts are running smoothly. Shortcomings always appear in one or several of the multi-die cavity, then the disadvantage often appear in the feed system (ie, service in the cavity of the flow channel or gate).
Processing: check the pressure, temperature and time recommended by plastic suppliers located. If the mold for another injection molding machine shortcomings disappear, drawback is probably because the issue of consistency of the processing conditions used in the production on the original machine. If another person to operate the injection molding machine shortcomings disappear, the shortcomings of the emergence of human error. Should check the speed of injection molding action of the management and security doors to open and close dwell time.
4, Determine the impact of the shortcomings, if the shortcomings of the injection molded parts can not be used or can not be sold, and this shortcoming must eliminate.
5, To determine where the responsibility, this may just be a research interest in the academic, but the drawback appears again, the operator of the original
Materials, injection molding machine, mold and process should be reviewed.
6, To take action to avoid the shortcomings. Can not take the appropriate action will produce poor injection molded parts and therefore surplus to the project
Injection shortcomings of each case, the shortcomings of the injection molded parts are usually caused by several factors: the operation of the injection molding machine, the function of the mold or plastic processing performance problems or defects usually have more than one of the causes. Each of the following shortcomings are recommended remedy under the heading of the injection molding machines, molds and plastic.
