补充资料:大型挤吹中空塑料成型机技术发展趋势
当前,缩短生产周期、提高生产效率是大型挤吹中空塑料成型机的重要发展方向。业内人士指出,国内企业对于该类设备的开发重点应当有所变化。
其一,要提高机器的塑化能力。应开发高塑化性能和高输送能力的螺杆机筒,大力推广、应用带强制喂料、强制冷却的高产量塑化挤出的“IKV”结构。
其二,要提高吹气压力、使用低温干燥高压空气吹塑,因为这是缩短吹塑冷却成型时间及提高制品质量的关键。
其三,为了提高储料式机头的性能,应研发高性能双层心形包络流道的储料式机头。由于先进先出、快捷换色换料以及清理方便是高性能储料式机头的重要特征,因此,在开发生产机器的过程中,应积极应用先进的CAD/CAE/CAM技术,采用优质的钢材和精密的加工设备。
其四,插销式无拉杆合模机构发展较快,它具有锁模力大、分布均匀、装卸模具容易、容模量大、节能等方面的优点,因此,应在大型挤吹中空塑料成型机中推广使用。
