At the Cutting Edge

We utilise cutting-edge technologies such as 3D-printed sand cores, casting simulation, and post-casting heat treatment development to achieve the mechanical properties essential for motorsport-grade castings.

Our in-house CT scanning and casting simulation technology, combined with our proprietary casting process, delivers consistently high-integrity results, with minimal defects and exceptional reliability, critical for F1, WEC, and endurance racing.

Materials Expertise

Our extensive materials knowledge enables us to deliver lightweight, high-strength castings, optimised for downsized, high-efficiency racing engines.

We ensure precision and quality using computed tomography (CT) scanning and rigorous tolerancing control, delivering lightweight castings that meet demanding performance specifications.

Short Lead Times

With deep experience in racing and rally engine and transmission programmes, we consistently meet the compressed lead times required by the motorsport industry.

Our innovative casting expertise ensures you receive the highest possible quality in both aluminium castings and CGI (compacted graphite iron) castings, optimising material performance for elite motorsport use.

Case Studies

The Gibson F1 Engine

Gibson GK428 engines, cast by Grainger & Worrall, were used by all 20 cars on the LMP2 grid. Grainger & Worrall have worked with Gibson Technology for many years, with engineers from both businesses collaborating to deliver reliable, accurate, F1-grade cast Gibson engines.

Flexible, Fast F1-Grade Castings With 3D Printing

Bringing 3D sand core printing in-house has allowed us to produce cores of almost any shape overnight. We use this cutting-edge technology to develop robust casting methods and adjust component geometry before final tooling for production.

This enables us to meet the extremely short lead and production times demanded by F1 customers. It also gives us crucial flexibility to modify designs.
