济南注塑加工之后需要进行模具的试模，主要作用便是测试下模具加工能不能满足塑胶制品的要求。那么接下来我们说说试模的步骤及注意事项。
Ji 'nan injection molding after the need for mold testing, the main role is to test the mold processing can meet the requirements of plastic products. Then let's talk about the steps of mold testing and matters needing attention.
济南注塑加工之试模的步骤
Ji 'nan injection molding process of mold testing steps
需要耐心调整和控制各种加工条件，避免不必要的时间浪费和批量生产的麻烦，制定标准的模具测试程序，找出建立常规工作的温度和压力条件。清洁机筒，防止降解的橡胶或其他材料注入模具，因为降解的橡胶和其他材料可能会堵塞模具，检查机筒和模具的温度是否适合加工原料。
Patience is required to adjust and control various processing conditions to avoid unnecessary time waste and the trouble of mass production, develop standard mold testing procedures, and find out the temperature and pressure conditions to establish routine work. Clean the barrel to prevent the injection of degraded rubber or other materials into the mold, as degraded rubber and other materials may clog the mold, and check that the barrel and mold are at the right temperature for processing the material.
尤其是模具型腔有些成品没有完全固化的时候，在调整各种控制条件之前要慎重考虑，因为充模率变化不大，可能会引起充模变化，耐心等待机器和模具的情况稳定。这个时间可以用来检查成品可能出现的问题。
Especially when some finished products of the mold cavity are not completely solidified, we should carefully consider before adjusting various control conditions, because the filling rate does not change much, it may cause the filling change, and wait patiently for the machine and the mold to be stable. This time can be used to check for possible problems with the finished product.
模具加热时，应适当延长螺杆的推进时间，以压实成品。调试成功后，运行少半小时稳定，然后连续生产少十几个全尺寸产品，标记日期和数量，测试其实际运行的稳定性，根据模腔分开放置，获得合理控制公差，测量并记录连续样品的重要尺寸。
When the mold is heated, the advance time of the screw should be appropriately extended to compacted the finished product. After successful commissioning, stable operation for at least half an hour, then continuous production of at least a dozen full-size products, date and quantity, test the stability of their actual operation, separate placement according to the cavity, obtain reasonable control tolerances, measure and record the important dimensions of continuous samples.

为了稳定熔体温度和液压油温度，使加工时间更长，根据所有过大或过小的成品尺寸调整机器条件。如果收缩率太大，成品看起来不够，也可以参考加大浇口尺寸。如果型腔尺寸太大或太小，请修正，如果型腔尺寸仍然正确，请尝试改变机器条件，检查是否有一些型腔填充缓慢，调整填充率和模具温度以提高其均匀性。检查并纠正注塑机的故障，即使是的模具在维护不善的机器上也不能正常工作，检查纠正后的样品是否有改善，检查所有记录值后保留一组样品。
In order to stabilize melt temperature and hydraulic oil temperature for longer processing time, machine conditions are adjusted according to all oversize or undersize finished products. If the shrinkage rate is too large, the finished product looks inadequate, you can also refer to increase the gate size. If the cavity size is too large or too small, correct it, if the cavity size is still correct, try changing machine conditions, check if some cavities fill slowly, adjust the filling rate and mold temperature to improve its uniformity. Check and correct malfunctions of injection molding machines, even perfect molds do not work properly on poorly maintained machines, check for improvement of corrected samples, keep one set of samples after checking all recorded values.
