Sequel Concepts Ltd
Sequel Concepts Ltd designs, builds, and maintains injection mold tooling and custom fabrication solutions — engineered by veterans and sharpened by new ideas.
Sequel Concepts Ltd is a world-class manufacturer of tooling for the plastics industry. Established in 2018, we continue to grow beyond our origins with a diverse team of industry-leading veterans and bright new talent with bold ideas. Industries served include agriculture, automotive, consumer and durable goods, medical, mining, powersports, and recreation.
We're conveniently located in the Windsor, Ontario area — the heart of manufacturing technology in Canada, just 15 minutes from the U.S. border — ready to service customers across North America. Feel free to call us at (519) 737-7867, or schedule an appointment with one of our highly skilled team members.
Tailored fabrication built around your part, from concept to finished piece. CWB certified, with structural steel and material conveyance capabilities. Typical builds include weldments, machine platforms, railings, stairways, tables, and fixtures — serving agriculture, heavy equipment, automotive, marine, and trailer-repair applications, plus machine guarding.
Production runs built to spec, one-off to high volume.
Full-range welding capability, down to precision micro laser welding.
Multi-axis CNC machining across 2D and 3D part geometry.
Deep-hole gun drilling and precision CNC turning.
High-precision abrasive waterjet cutting on our 8x20' tables.
Design and product development runs on Cimatron 15 and VISI by Hexagon — recognized globally among the top PC-based CAD/CAM solutions for the mould and die industries. VISI enhances our capabilities with robust modeling, detailed analysis, and flexible machining strategies, supporting complex design validation, kinematic simulations, and comprehensive mold design processes.
Advanced, highly automated machining processes, including gundrilling in configurations up to 9 axes, multi-axis automatic drilling for palletized machining centers, and 2-5 axis machining with multi-face, multi-pallet tombstone management.
Our team travels to your facility to perform minor mold repairs and maintenance, keeping your production running without the tool ever leaving your plant.
Full mold refurbishments, preventative maintenance, and troubleshooting to keep tools running to spec over their full production life — plus new complete tool builds.
Hot runner manifold repairs supported by a 24-zone fast heat controller for precise, zone-by-zone diagnostics.
Sequel Concepts Ltd supports medical device programs with tight-tolerance injection molds and precision-machined components, produced under our ISO 9001-certified quality management system. Every job runs through the same documented, repeatable process — from first-article inspection to final part — so molders and OEMs can count on consistent, traceable results run after run.
For automotive programs, Sequel Concepts Ltd builds production and prototype tooling designed to hold up over high-volume, high-cycle runs. Our in-house 5-axis machining, EDM, and custom fabrication capabilities let us take a tool from design through validation without handing work off to outside shops — keeping lead times tight and tolerances consistent across the full production life of the part.
Part geometry, gate location, and cavity layout are reviewed for moldability before quoting.
A firm mold construction plan and lead time are issued against your part print or 3D model.
Steel is machined, EDM'd, and hand-fit to spec on our shop floor in Oldcastle.
First-shot samples are pulled, measured, and adjusted until the tool is production-ready.
Ongoing maintenance and engineering changes keep the tool performing over its full life.
