? Thetask

Welding PTFE membranes.

A lid is to be attached to an electronics housing

for the automotive industry and welded to be

watertight.

In such applications it isusual to weld a PTFE

membrane into the housing so that any existing

moisture can escape and the pressurecan be equalized.

These membranes are very delicate and cannot be

welded to allbase materials of the housings using

longitudinal ultrasonic welding. （PA6.6 GF40）

? Thesolution

In this case the task was reliably accomplished

using the torsional TSP750technology.

The application runs fully automatically.

? The advantages

With torsion it is possible to achieve a secure and

leak-proof connection between PTFE membranes

and a range of different materials,including those

with a high proportion of glass content.

The membranes are not damaged in any way.

When fitted with vacuum technology, thesonotrode

canretrieve the pre-punched membrane froma

magazine and weld it into the part. No handling

unit is required;the process is very secure and fast.

A vacuum sonotrode can also be used to punch

the required membraneshape from a tape and

simultaneously weld it into the part.

?任务

焊接聚四氟乙烯膜。

盖子被安装在电子设备壳体对于汽车行业和焊接要水密。

在这样的应用程序通常是焊接聚四氟乙烯膜进入住房，任何现有的水分可以逃脱压力可均衡的。

这些膜是非常微妙的，不可能焊接的所有基础材料外壳的使用纵向超声焊接。（PA6.6GF 40）

?溶液

在这种情况下，可靠地完成任务采用扭TSP750超声波扭距技术。

应用程序*自动运行。

?的优点

扭可以实现一个安全聚四氟乙烯膜之间的防漏连接和一系列不同的材料，包括随着玻璃含量比例高。

膜是不以任何方式损坏。

当装有真空技术，超声波焊头可以检索从预打孔膜杂志和焊接到部分。没有处理单元是必需的；这个过程是非常安全的，快速的。

真空发生器也可以用来冲所需的膜的形状从磁带和同时焊接成的部分。
