Ewikon says they consist of a gate exchange insert with high-precision machined inner contour and gate bore and a matching nozzle tip insert. The gate exchange insert is installed directly in the contour insert and can be replaced easily in case of wear.

This development solves a common problem, the company explains. When operating valve gate systems, the gate area is said to be especially liable to wear, causing a loss of dimensional accuracy of the gate bore.

The consequence is a deterioration of the part quality. Even technical features like the permanent valve pin guide near the gate can only minimise the gate wear but in the long term not completely avoid it. Up to now the affected contour inserts or even contour plates had to be replaced. According to the supplier, this can be avoided with the Ewikon gate exchange inserts.
