FREQTIS的成形技术Molding technology for FREQTIS Freqtis 的注射成型Injection Molding of FREQTISFreqtis 分为基于 LCP 的等级和基于 PPS 的等级两种。：FREQTIS includes two grades, one grade based on LCP and one based on PPS.下面介绍 Freqtis 的成型条件（按基础树脂分项说明）Here, the following introduces the molding conditions of FREQTIS and provides a separate description for each base resin depending on itemLCP 基 PPS 基C0511AC0711AP0813AP1210AP2020A机筒温度后部320325290300中部325335300前部335345310喷嘴320350310320模具温度70150135150LCP basePPS baseC0511AC0711AP0813AP1210AP2020ACylinder temperatureRear part320 - 325290 - 300Middle part325 - 335300Front part335 - 345310Nozzle320 - 350310 - 320Mold temperature70 - 150135 - 1501. 预干燥Preliminary dryingFreqtis几乎不吸湿，但为了改善其外观并防止流涎和劣化，建议进行预干燥处理。Although FREQTIS hardly absorbs moisture, we recommend preliminary drying in order to improve the appearance of mold products and to prevent drooling and deterioration. 推荐条件：Recommended conditions:温度：140160时间：46 小时Temperature: 140 to 160Time: 4 to 6 hours2. 机筒温度Cylinder temperature推荐条件如下：Recommended conditions are described. C0511A, C0711A（LCP 基） C0511A, C0711A (LCP base)后部：320325 Rear part: 320 - 325中部：325335 Middle part: 325 - 335前部：335345 Front part: 335 - 345喷嘴：320350 Nozzle: 320 - 350 勿使树脂温度超过 360。Do not set the resin temperature to 360 or more.极限滞留条件：30分钟350Limit residence in cylinder condition: 30 min x 350 P0813A, P1210A（PPS 基） P0813A, P2110A (PPS base)后部： 290300 Rear part: 290 - 300中部： 300 Middle part: 300前部： 310 Front part: 310喷嘴： 310320 Nozzle: 310 - 320因产品形状而需要高流动性时，也可将上述温度调高 20 左右。If high flowability is required depending on the product shape, the temperature can be lowered by approximately 20 less than the above.3. 模具温度. Mold temperature推荐条件如下：Recommended conditions are described. C0511A, C0711A（LCP 基）C0511A, C0711A (LCP base)70150为了改善成型品外观并确保流动性，建议尽可能在较高的模具温度下进行成型。In order to improve the appearance of mold products and secure flowability, it is recommended to mold as high a mold temperature as possible. P0813A, P1210A（PPS 基） P0813A, P1210A (PPS base)130150PPS 物性会受到模具温度的很大影响。he mold temperature greately influences the PPS physical properties.请勿在 120 以下的模具温度下进行成型。TDo not mold at a mold temperature of 120 or less.4. 螺杆转速Screw rotational rate推荐条件如下：Recommended conditions40 - 100rpm5. 背压Back pressure0.0 - 1.0Mpa如果计量不稳，建议稍微提高背压（2.03.0MPa）。6 注射速度 Injection speed推荐条件如下：Recommended conditions are described. C0511A, C0711A（LCP 基）C0511A, C0711A (LCP base)LCP 的固化速度很快，因此建议多采用高速注射。High speed injection is recommended in most cases because the LCP has a high solidification rate. P0813A, P1210A（PPS 基） P0813A, P1210A (PPS base)为了获得良好的外观，应进行高速注射。In order to achieve an excellent appearance, high-speed injection is required.不过，高速注射容易导致翘曲和烧焦，因此只要能够达到外观良好，一般无需过度使用高速注射。However, since warpage or burn is likely to occur, thypically a high-speed injection more than necessary is not required if the appearance becomes excellent7.注射压力Injection pressure推荐条件如下：Recommended conditions are described. C0511A, C0711A（LCP 基）C0511A, C0711A (LCP base)最佳注射压力会因产品形状、模具设计以及其他成型条件而异The optimal injection pressure varies depending on the shape of the product, mold design, and other molding conditions, etc.。最好在较低的压力下开始，然后逐渐提高压力。The best method is to start molding at a low pressure and gradually increase the pressure.大部分成型品都可在 1545Mpa 的树脂压下进行成型。Almost all mold products can be molded at resin pressures of 15 to 45 MPa. P0813A, P1210A（PPS 基） P0813A, P1210A (PPS base)通常最好采用 30100 Mpa 的注射压力；为了减少飞边，建议在低压下进行成型。Normally, injection pressures of 30 to 100MPa are favorable, and molding at low pressures is recommended to prevent burrs.8. 成型后的清洗 Purging after molding通常，在保持成型时的温度的状态下，先用含有玻璃纤维的聚碳酸酯清洗，接着用聚乙烯清洗，然后再用两者反复交替清洗。We recommend to, first, purge with polycarbonate containing glass fibers while maintaining a molding temperature, purge with polyethylene, and repeat purging with polycarbonate containing glass fibers and polyethylene, alternately.为了提高清洗效率，应将机筒内的清洗材料完全排出后再装入下一种清洗材料。can be more effectively carried out by completely discharging a purging material in the cylinder and placing the next purging material.也可用市售的丙烯酸类清洗材料来代替含有玻璃纤维的聚碳酸酯。In addition, purging In place of polycarbonate containing glass fibers, commercially-available acrylic purging materials can be used.9. 安全上的注意事项 Safety precautions成型作业中断 30 分钟以上时，应清洗机筒内的树脂并将机筒温度降至 50 左右。If molding work is suspended for 30 minutes or more, purge resin in the cylinder, and reduce t
