Learn moreWhy SYNC
More capability. Less complexity.
Bringing specialized manufacturing processes together only matters if it makes business easier for our customers. Sync connects material expertise, manufacturing capabilities, and responsive teams across our locations through one coordinated manufacturing platform.
Material expertise in-house
Our rubber compounding capabilities let us develop and adjust materials to meet application requirements, performance needs, and operating environments.
Multiple processes. One manufacturing partner.
Plastic molding, rubber molding, dip molding, cutting, bonding, compounding, and value-added operations give customers access to a broader range of manufacturing solutions without managing a broader supplier base.
Coordinated quality and program support
Our teams work together around customer requirements, traceability, documentation, and consistent execution. We maintain certifications and registrations at qualified locations based on customer and program requirements.
Support for legacy and hard-to-source components
Scan-to-part modeling, tooling capabilities, and manufacturing experience can help bring older or difficult-to-source components back into production, even when original tooling or complete documentation is no longer available.
