    • Apparatus and method for producing extruded polymer products such as hollow extrusions and conductor coatings having wall thicknesses of 0.002 inches or less. The apparatus may comprise more than one of the following: an external heat source; temperature measurement and heater control; video monitoring equipment to allow magnified observation of the extrudate, thereby providing opportunity to observe any deficiency in the extrudate; and a die holder and die allowing for more expedient die adjustments. A method for producing ultra thin walled extruded polymer products that comprises the following steps: heating the extrudate as it leaves the die, controlling the heat source through either temperature sensing device and heater controller responsive to the temperature sensed, electric current regulation, or electrical voltage regulation; monitoring the extrudate with video equipment to ensure uniformity of the walls of the extrudate; and adjusting the die during extruder operation in response to any observed deficiency in the extrudate.
    • 用于生产挤出聚合物产品的设备和方法,例如具有0.002英寸或更小的壁厚的中空挤压件和导体涂层。 该装置可以包括以下的多于一个:外部热源; 温度测量和加热器控制; 视频监控设备,允许放大观察挤出物,从而提供观察挤出物中任何缺陷的机会; 以及允许更方便的模具调整的模座和模具。 一种制造超薄壁挤出聚合物产品的方法,包括以下步骤:当挤出物离开模头时加热挤出物,通过温度感测装置和加热器控制器响应于感测温度,电流调节或电压来控制热源 规; 用视频设备监测挤出物,以确保挤出物的壁均匀; 并且在挤出机操作期间响应于在挤出物中观察到的任何缺陷来调节模具。
