哪里卖三位双面无缝焊接机？塑钢无缝焊接机是塑钢焊机中高等的焊接设备，是焊接彩色塑钢型材的一种高等的加工设备。

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

塑钢无缝焊接机分单面无缝焊接机、双面无缝焊接机。单面无缝焊接机是适用于单面彩色的塑钢型材；双面无缝焊接机是适用于双面彩色的塑钢型材。现在市面上单色彩色的塑钢型材相对来讲占市场大多数。

塑钢无缝焊接机同样按照机头数量的不同分为：二位无缝焊接机  三位无缝焊接机  四位无缝焊接机
一般三位无缝焊接机 和 四位无缝焊接机用的较多。

塑钢无缝焊接机的详细介绍：

1）非常适合贴膜、转印、双色共挤、喷涂等彩色型材的焊接
2）焊接完成后将焊榴一次性清理完成，并可以严格控制焊接的缝隙大小，因此对彩窗型材焊接完成后，   表面焊口十分美观、高等，焊接强度高于原有型材的角强度。
3）通过控制和气动系统，对焊接强度进行了增强处理模式，尤其是在融化、融-焊间隙、对焊过程中的软   件处理，保证在不同环境情况下的焊接强度非常大，并可以通过数字参数进行量化调节。
