Overview
Sand cores for automotive castings
Cores form the inside of a casting — the passages, cavities and bores you can't make with the mould alone. A good core holds its shape, releases its gas and breaks out cleanly.
Our core shop runs 5 core shooters for hot box and cold box cores, with 20+ core box variants maintained in-house. Most of our output goes to CIE Automotive, a customer that accepts zero defects.
Because the sand comes from our own RCS plant, the biggest variable in core quality is controlled at the source.

Process
From core box to dispatch
Tooling check
Core box inspected and set up; parameters taken from the approved process sheet.
Shooting & curing
Sand shot into the core box and cured — pressure, temperature and cycle time logged.
Stripping & finishing
Cores removed, fins cleaned and assembled or pasted where needed.
Inspection
Dimensional and visual checks per batch; rejects recorded against machine and box.
Packing & dispatch
Cores packed to protect edges and delivered to your foundry schedule.
Core development
Have a new core box? Let's run trials.
Share the core drawing or box and your monthly requirement. We'll plan trials and a sample lot.
