Pass core injection moulding: why it is important

Components of an injection mould

The moulds used in injection moulding are generally composed by two different parts:

Fixed mould
Mobile mould

During the injection moulding process, these components are mounted on the fixed and movable moulds, respectively, that are located on the injection moulding machine.

Fixed and movable mould together form a casting system and a cavity, the part where the plastic material takes the shape of the final product.

Generally, the fixed part of the mould is functional for insulating and securing the plastic material and supporting the dowel containing the half mould. It is usually considered the female part of the mould.

On the other hand, the mobile component, separating from the fixed part, allows the extraction of the final product.

Core injection moulding

A fundamental element of any injection mould is the core, the soul of the mould, which is fundamental for the shape of the final product. Precisely for this reason, its design and realization require precision and attention at the highest levels.

The core injection moulding sees among its main components the gate and the runner.

The runner is the channel through which the plastic material, once melted, passes to reach the central cavity of the mould: the pass core injection moulding. The gate is the entrance to the actual cavity.

From pass core injection moulding to the final product: the quality of Idea Stampi

From the core to the realization of the product: there are many variants that need to be considered in the construction of a mould, starting from the preliminary analysis about the product, the material, the gate position, the conditioning and the thickness optimization.

That is why Idea Stampi follows the whole process internally, from the 3D designing to the final testing, in order to give the customers burable, precise and customized moulds.

Designing

Since the design stage, with a high involvement of the customer, the main goal is to realize an accurate mould.

How?

Identifying the best gate position, optimizing the size and thickness of the runner and all the other components that make up the core injection moulding.

Thanks to software CAD/CAM /CAE and integrated moulding simulation systems, Idea Stampi experts are able to realize durable and precise moulds.

Production

Starting from the 3D model developed during the design stage, every single part of the mould, from the core to the mobile elements, can be processed and realized with the utmost precision.

The result is the construction of the injection mould, usually made of cast iron or steel.

Testing and inspection

The process of construction of injection moulds ends with the testing of the moulds using presses from 25T to 180T.

This is an operation to guarantee the quality of the moulds themselves, an advantage for the customers who can have the security of the product they buy.

In addition, Idea Stampi offers the possibility of realizing prototypes and, on request, guarantees a service of pre-series production, optimizing the injection moulding cycle of the customers.
