Since opening in 2004, Starlim North America’s London plant has grown into a flagship LSR injection-molding facility. Originally 65,000 ft² with five injection presses, it underwent a major $20 million expansion between 2016 and 2018 to add 180,000 ft²—including three new production bays, post-curing ovens, and ISO 7/8 cleanrooms—tripling capacity without disrupting ongoing production. The building features a two-story office tower and an innovative basement-level dosing system that supports 24/7 automated operations using ENGEL injection machines.
Manufacturing at the facility focuses on high-volume, precision liquid silicone rubber (LSR) parts—primarily for the life sciences (≈50%), automotive (~30%), and industrial (~20%) sectors—with defect rates as low as 0.5 parts per million. The 235,000 ft² state-of-the-art facility operates year-round with a workforce of around 150 employees and over 80 molding machines. It serves as a key North American manufacturing hub, supplying components to both domestic and international markets.
The Starlim North America facility in London, ON incorporates multiple structural systems optimized for high precision manufacturing and hygienic conditions. The original structure uses cast-in-place concrete foundations and slabs, with structural steel framing supporting long-span roof assemblies over expansive production zones. A two-storey below-grade water reservoir necessitated advanced waterproofing and buoyancy control measures, including a 1,100 m³ cooled concrete pour to mitigate thermal stresses during summer placement. The 2016–2018 expansion integrated new cleanroom environments with stringent vibration and deflection criteria. Phased construction sequencing and temporary support systems enabled uninterrupted 24/7 operations while maintaining structural integrity and worker safety.
