Coremaking.
High-Volume. Built for Complexity.
In-house core production at high daily volumes — including complex geometries that other foundries send out.
Excal’s coremaking operation gives us direct control over one of the most critical variables in casting quality. With multiple core material options and several dedicated machines, we produce high volumes of complex cores daily — without outsourcing or delays.
Why In-House Coremaking Matters
Control Over Every Internal Feature
Cores define the internal geometry of your casting. When coremaking is in-house, we control the schedule, the quality, and the consistency.
Multiple Core Material Options
We work with multiple binder systems and core materials to match your alloy, complexity, and production volume requirements.
Dedicated Core Machines
Multiple dedicated coremaking machines give Excal the throughput to produce high volumes of cores daily — keeping our molding lines running without interruption.
High Daily Throughput
Coremaking capacity is matched to our molding line output — so complex cored castings don’t create bottlenecks in your production schedule.
Our Process — Coremaking
From Core Box to Casting
Core Design Review
We review your part drawing to determine core geometry, material, and placement within the mold.
Material Selection
Core material is selected based on alloy poured, part complexity, and required surface finish on internal features.
Core Production
Cores are produced in-house at high daily volumes using our dedicated coremaking machines.
Integration & Quality Check
Cores are inspected and staged for molding — ensuring fit, placement, and dimensional accuracy before the pour.
