How are cable ties made?

Plastic cable ties are manufactured using an injection moulding process. This manufacturing process makes it possible to produce a large number of cable ties per operation cycle. The following steps are required to make cable ties:

1. Plasticising

Plastic granules are used as raw materials and melted by applying heat. This process is called plasticising.

2. Injection

The liquid plastic is then pressed into the cavities of the mould at high pressure and speed. This step of the cable tie manufacturing process is called injection. The molten plastic takes on the shape of the cavities in the mould.

3. Cooling

The next step in the manufacturing process is cooling. The mould is significantly cooler than the plasticised material causing it to cool and eventually solidify.

4. Demoulding

Once the plastic has solidified, the cable ties are pushed out of the mould. This process is referred to as demoulding. Next, the sprue must be removed from the cable ties. This is a piece of plastic that connects and holds all cable ties together. As soon as the demoulding is complete, the mould closes again and the manufacturing process starts anew.
