模切橡胶
The process of die cutting is much like making cookies using cookie cutters. The material, either in sheet or strip form, is fed into or through a machine where the die or dies are then lowered using force to cut the part's shape. Steel rule dies are the customized tooling used for die cutting rubber. They are razor sharp and are built to last the toughest production requirements.
在确定切割过程是否是您特定应用程序的最佳选择时,需要考虑一些标准。一个考虑因素是材料的厚度 - .25或更少的材料厚度最适合此过程。材料比.25英寸厚的材料可以产生效果,这是当材料在外边缘上具有凹形的外观时切割后。这种盘子可能会或可能不会影响零件的整体功能。
要考虑的其他标准是该零件是否由任何平方或90度边缘组成。如果确实如此,则可以考虑切割。如果边缘上有半径,则不能使用切割过程,而应考虑模制过程。
要考虑进行切割的申请包括符合上述标准的任何平坦组件。许多弹性体和非弹性材料都有利于割伤,而且实际上,当前市场上目前可用的所有弹性材料都可以有效地削减。一些非弹性材料(例如聚酯薄膜和软木)也是此过程的良好候选者。
车床切橡胶
车床切割过程需要挤出一管橡胶,将其切成指定的长度,将其滑到曼德斯(Mandrel)上,固化材料,然后用床铺将OD磨碎,然后将成品零件切成长度。
Parts suited for this process are washers and gaskets requiring precision to high precision tolerances. Square cut edged, (or 90 degree edge), components are best suited for this process; however, in some cases a beveled edge can be incorporated. Most118bet.net金博宝app 今天可以使用车床切割过程生产。
此过程的典型应用是从花园软管中使用的小洗衣机到用于密封桶或鼓盖的大型垫圈。一般而言,大量应用最适合此制造过程。
mandrel形成管道
The process of mandrel forming is both labor intensive and unique. The process begins with the material being extruded to a specified outside and inside diameter and then cut to a specific length. Through a process called "sticking", the tubes are then placed, or pushed, onto a mandrel in the shape of the finished part. For large volume applications, a rack of mandrels is built onto a cart. Once the tubes have been "stuck", the cart is then moved into the autoclave for curing. After curing, the parts are pulled from the mandrels. In most cases the parts are moved to a washing machine of sorts to rid them of release agents and other material used during the process. After washing the parts the ends are trimmed to length using a chop saw.
Typical applications for mandrel formed parts include components where kinking in a straight tube could occur if bent. Simple 90 degree bends as well as more complicated multiple bends are common to this process.
最多materials active on the market today are suitable for mandrel forming in durometers from 50-80.
Punching
打孔的过程是当需要在挤出配置文件上进行任何形状和尺寸的孔时使用的二次操作。打孔夹具用于使用与模切切割大致相同的方法来打孔。
A typical application for the punching operation is when an extrusion requires screw holes for securing purposes. Most materials available on the market today are conducive to this process.
剪接
剪接过程是当需要作为成品零件的剪接的无尽循环时使用的辅助操作。与成型相比,这可能是一种更具成本效益的处理方式,因为工具可能要便宜得多。
该过程始于将指定的轮廓挤压成大量素材。然后,使用一种可用的固化方法将材料固化;高压釜,盐浴或微波炉。材料固化后,根据成品部分的周长将其切成长度。现在,该零件已经准备好拼接了。有两种可用的方法;冷剪接和剪接成型。
挤出的两端使用橡胶兼容的粘合剂形成无尽环的冷剪接过程,也许是最常见的。此过程最适合不需要拼接上极度紧张的静态应用。通常不涉及添加的工具,因此成本保持合理。该过程本身非常简单。将粘合剂应用于挤出的两端,然后将其压在一起,直至干燥(固化)。可能会从粘合剂上散发出一些出血到轮廓的外表面 - 这很常见。
通常使用的第二个剪接方法是称为剪接成型的过程。此过程需要在配置文件的配置中使用剪接模具机械键合的剪接。很简单地,它像成型工艺一样,使用热,压力和未经许可的橡胶将关节结合在一起。这个过程有几个优点。首先,热剪接中键的强度优于冷键方法。如果申请要求将零件拉伸或拉伸到任何程度,则建议进行此过程。不仅可以将挤压剪接到无穷无尽,而且如果需要“图像框架”设计,则可以将角剪接成剪接以实现所需的效果。
最多118bet.net金博宝app 可用与此过程兼容。通常,此过程的最常见用途是空心的圆形垫片应用。
