Thermal break profile extrusion molds are always equipped on single screw plastic extruding machine. They are used for producing and shaping PA thermal break strips.

What is plastic moulds for PA profile extrusion line?

PA profile means polyamide thermal break strips. Which is one of the most common materials used for years to create thermal breaks in curtain walls, commercial windows, doors, and more. It is a reinforced polyamide strip, which occurs as a non-metallic, composite, structural material, and is installed between the interior and exterior profiles of the windows that forms an insulating barrier between the two.

The shape, size and output of polyamide strips are determined by plastic moulds. Therefore, plastic mould is a very important and indispensable part of the polyamide strips extrusion line.

Polyamide Thermal Strip Processing Process

PA66GF25 granules are dried and get into the machine barrel through the hopper. The granules are in rotary contact with the machine screw, and move towards the mold with the rotation of the screw.

As the gap of machine screw and barrel is small, the granules are heated in the gap under the process of moving forward. They are plasticized to nylon molten state through the high temperature of the electric heating ring body. The molten state of nylon is diverted and shaped after entering the mold, and finally extruded into heat insulation strips.

What is extrusion molding used for?

Extrusion is a manufacturing process used to make pipes, hoses, drinking straws, curtain tracks, rods, and thermal break profiles. The granules melt into a liquid which is forced through a die, forming a long 'tube like' shape. The shape of the die determines the shape of the 'tube like' products.

Advantages:

1. Our engineers follow the molds' production every week to make sure that all of them are in schedule.

2. We continuously optimize the runner design to make the die convenient for operation and material extrusion.

3. We will put forward professional revision opinions according to customer's drawings, and optimize drawings according to customers’ requirements.

4. If everything is OK, we will do final inspection on the molds and products before shipment.

5. After the customer receives the mould, if there is any problem in using it, we can go to the door and provide on-site guidance.

Our service of mold design and development:

The precision of the tool is the key to the quality of the part. Tool making is an art. That's why we manufacture and test our tools to the strictest quality standards. Whether you need a tool for prototyping or high volume multi-cavity production, we will get it done quickly and accurately.

Packing & Delivery:

We usually put each mold into a plywood case to make sure the mold is safe during the whole transport process. 

The weight of each mold is around 60-200kg. It depends on the mold sizes. 

We usually need 28-35 working days to produce a mold. After that, we will do the mold test to make sure both the mold and the polyamide strips produced by this mold are qualified.
