Extrusion blow moulds and their design requirements

There is one thing people look for in their necking profile gauge. This is a tool that meets their specific requirements. Thanks to the skills of our team members, we are more than capable of creating them. If mould repair operations are essential for you, our products will make things much easier.

The design needs of extrusion blow moulds are essential when creating these items. An extrusion blow mould is primarily two halves of a female die. Usually, it has a guide column, a mould body, and a blank opening. In addition, there is a moulded neck, a blank cutting sleeve, and a mould cavity.

Design requirements

There are numerous elements to the extrusion blow mould's design requirements. This includes the need for inserts within the extrusion blow mould. A separate insert is normally supplied at the bottom of your blow mould. You do this to seal and squeeze one of the parison ends as well as cut the tailings off.

When developing the mould bottom inserts, the tailing slot and blank cutter are two details you must consider. The two have a major influence on the performance and forming of the products. As a result, you need to meet several requirements.

Wear resistance, rigidity, and strength

For one thing, the mould has to possess sufficient wear resistance, rigidity, and strength. Within the replicated mould clamping operation, it is exposed to the pressure created by the parison melt's extrusion. The blank area's thickness is also typically bigger than the product wall's thickness. More heat is produced too.

Those inserts that form the container's neck primarily include a shear block and mould neck ring. This shear block will be above your mould neck ring. This assists you with cutting off the neck residual material. What's more, you can lower the mould neck ring's wear.
