Stockwell Elastomerics invests more than $8M to expand Philadelphia operations

Stockwell Elastomerics is spending more than $8 million to add facility space, equipment and engineering staff at its Philadelphia campus. The expansion is designed to lift manufacturing capacity, speed production and support customers in aerospace, defense, medical, semiconductor and other technical markets.

Why it matters: - The investment expands Stockwell Elastomerics' ability to move prototype work into production faster. - The added capacity is aimed at customers that need precision silicone and elastomeric components in regulated and high-specification industries. - The project also strengthens the company's engineering, quality and customer support functions as demand grows.

What happened: - Stockwell Elastomerics announced a more than $8 million investment in expanded facilities, manufacturing capacity and engineering talent. - The Philadelphia-based company acquired an additional building next to its current corporate campus. - The company added new manufacturing equipment and technical resources to support continued customer growth. - Stockwell Elastomerics serves aerospace, defense, medical devices, semiconductor manufacturing, electronics, instrumentation and other technology-driven industries.

The details: - The new adjacent facility adds 38,000 square feet to the campus. - The total Stockwell campus will exceed 100,000 square feet. - During 2026, Stockwell Elastomerics will complete facility planning, infrastructure upgrades and renovations. - Manufacturing operations in the new facility are expected to begin in 2027. - The expansion supports custom silicone molding, fabrication and assembly. - The company added three compression molding presses. - Stockwell Elastomerics also added a Liquid Injection Molding press. - Additional manufacturing infrastructure is in place to support higher production volumes and shorter project timelines. - The new compression molding equipment increases capacity for custom-molded elastomer components. - The LIM press is designed to produce highly repeatable, precision-molded silicone parts for tight-tolerance applications. - The equipment expansion broadens support for prototype and production work across silicone, fluorosilicone, conductive elastomer and specialty engineered material applications. - Fifteen recent hires expanded the applications engineering, customer service and quality teams. - The company maintained its ISO 9001 and AS9100 certifications. - Stockwell Elastomerics is also registered under ITAR.

Between the lines: - The expansion signals a push to deepen the company's role as a manufacturing partner, not just a parts supplier. - The mix of facility space, molding equipment and engineering hires points to a focus on end-to-end support from design through production. - Maintaining ISO 9001 and AS9100 certifications matters for customers in aerospace and other regulated sectors that prioritize traceability and process control. - President Tom Rimel said the investments are driven by customer needs and are aimed at helping customers bring products to market faster while reducing risk.

What's next: - Stockwell Elastomerics plans to finish planning, infrastructure work and renovations in 2026. - Production in the expanded facility is expected to start in 2027. - The company says it will keep investing in sales and engineering teams, supplier and manufacturing partnerships, R&D, quality systems, automation and prototype-to-production capabilities. - Stockwell Elastomerics says the long-term goal is to remain the preferred engineering and manufacturing partner for high-performance elastomeric solutions.

The bottom line: - Stockwell Elastomerics is betting that more space, more equipment and more specialized talent will help it capture growing demand for custom silicone and elastomeric components.
