Mold Used To Produce Thermal Barrier Strip Extruion Moulding Die

The supply of PA66GF25 insulation strip extruding machine
Polywell has its own design and development of nylon insulation strip automatic extrusion production line with high stability, high yield, high adaptability.


The utility model mainly uses the special screw to make the polyamide and the glass fiber mixed good.
Heat insulating rubber strips are widely applied to the doors, windows and curtain wall aluminum sheets through the different sections of the die.

Detail introduction:
PA66 granules and fiber glass are dired and get into the barrel through the hopper. Screw and pellets contact with the rotation of the screw is forced to promote the spiral groove die direction.
Because the screw barrel gap is small, the granule material is hot body under great pressure in the forward process, it is plasticizied to nylon thermosol through the high temperature of the electric heating ring body. Nylon plastic and plastic compression heating hot melt by extrusion molding, after traction, cutting or rolling become adiabatic adhesive tape products.


The host adopts imported inverter and traction, speed stability, ensure the main, auxiliary synchronous speed.
We use German technology to make the mould, so the surface of thermal insulation strips are beautiful, accurate shape and with high strength.
We use imported Japanese RKC temperature control table, so that the accuracy of the temperature can be controled in ±1 degrees.



Our Advantages:
1. Our engineers follow the molds' production every week to make sure all of them are in schedule
2. After trial production, we will check the samples to make sure everything is right

3. We will send the sample and dimension report to our clients for approval
4. After everything is ok, we will do final inspection on the molds and products before shipment.


Shape: We can make the shape according to customers' requirements.
Package: Plywood case




Please feel free to contact us if you have any questions.

We have been making research and development for special material of PA66GF25 thermal break strip since 2006, we have a deep understanding and rich experience of the relevant industry. We can provide our clients with special material of PA66GF25 thermal break strips of all levels. During these years, we also established a good partnership with many companies is the upstream and downstream industry.

In 2016, we together with factory of mold, extruder and factory of thermal break strips established Zhangjiagang Bangyu Engineering Plastics Co.,Ltd, which is responsible for international import and export business. In 2021, Zhangjiagang Bangyu Engineering Plastics Co.,Ltd was changed ans registered as Suzhou Polywell Engineering Plastics Co.,Ltd.
The reason why we joined Polywell together with the other two companies is that in this field, the requirements for professionalism are very high. In this field, the company that produce raw materials usually do not research machines and molds, but clients usually need all of them. We found this point, so we joined two other companies established Polywell company together. Polywell can provide a whole set of solution about thermal break strips, including raw material –PA66GF25 granules, extruders, molds, and technical support. This is our biggest advantage.

Strive for customers’ satisfaction and success, service to customers is the principle we’ve always been insisting in the last ten years, to provide our customers with high-quality products and service.

Our domestic sales volume is very stable. We are the main supplier of two listed companies which produce aluminum profile at home, and will obtain the long-term cooperation with them. Otherwise, we also have the long-term cooperation with many small manufactures.

If customers have the need of purchasing other products, we can also provide procurement service.
