Engineered plastic thermal insulation strips are essential components for the insulation of modern window, door or metal curtain wall systems.Thermal insulation strips make a significant contribution to excellent insulation and savings

Raw material : PA*6 POLYAMIDE STRIP

1:Knurling machine

Knurling is the first step in the production process,produce teeth in both alu profile 

To Knurl aluminium extrusion profile by hard gear .

 Proper knurling is required to insure guarantee shear strength of the composite profile

Teeth depth: between 0.*5~0.3mm, distance between teeth center-lines should be no greater that 0.*8mm

2:Strip feeding machine:

Thread the strip into the groove of the aluminium,the two knurled extrusions held together by thermal strip, this loose assembly gets transferred to the crimp or rolling machine

3: Rolling machine(Crimping machine):

The crimping process uses three sets of rollers, which put pressure on the aluminum groove and heat insulation tape.

To mechanically lock it in place, forming a bond between the two extrusions and the insulating strip.

The assembled aluminum strut profiles then act as a composite to transfer loads. over **0kg of pressure is applied in stages to crimp the aluminum. The first set of wheels applies *0 of the pressure while the decond set applies **0 percent. The third set of wheels help to straighten the extrusion and completes the crimping process
