High Pressure Zinc Die Casting

Norfran specialises in high pressure zinc die casting — a proven manufacturing process that delivers complex, precision components at high volumes, with minimal post-processing required. Molten zinc alloy is injected into hardened steel moulds under high pressure, producing parts with tight tolerances, excellent surface finish, and consistent repeatability across large production runs.

Components can achieve intricate geometries, sharp detail, and smooth or textured surfaces straight from the tool, making them suitable for a wide range of industries and applications.

Our Facility

Norfran’s high pressure die casting foundry offers an extensive range of machinery, providing flexibility across varying component shapes, sizes, and production volumes. We have significant experience manufacturing pressure-tight castings, as well as castings with integrated components such as fasteners, pipes, and electrical inserts.

As part of our continuous investment programme, we operate [X] fully automated die casting cells, each equipped with ABB 6-axis robots and 2-axisCNC spraying systems — typically deployed for high-volume, long-running production. A further 4 semi-automated machines handle smaller production runs with the same level of quality control.

Our facility houses 4 hot chamber zinc die casting machines ranging from 20 to 200 tonne, with casting weights from 0.002 kg to 9.00 kg.

Norfran also has cold chamber aluminium die casting machines ranging from 180 Tonne to 800 Tonne.

The Advantages of High Pressure Zinc Die Casting

High speed production

Die casting delivers complex shapes to closer tolerances than most other mass production processes. Little or no post-machining is required, and hundreds of thousands of identical castings can be produced before tooling needs replacement.

Dimensional accuracy and stability

Parts produced by die casting are dimensionally stable, durable, and heat resistant, consistently holding close tolerances across long production runs.

Strength-to-weight ratio

Die casting is well suited to thin-wall designs that reduce component weight without sacrificing strength. Multiple features can be incorporated into a single casting, eliminating the need for assembly joints or fasteners — meaning the structural integrity of the part relies on the alloy itself, not a secondary joining process.

Multiple finishing options

Die cast parts can be produced with smooth or textured surfaces and are easily plated or finished with minimal surface preparation required.

Simplified assembly

Die castings can incorporate integral fastening elements such as bosses and studs. Holes can be cored to tap drill sizes, and external threads can be cast directly into the part, reducing downstream assembly time and cost.
