Custom Injection Molding Services
Through our sister company, SR Plastics, we offer comprehensive injection molding services that complement SR Machining’s precision manufacturing capabilities. This partnership provides customers with a single, vertically integrated source for both molded and machined components — streamlining procurement, improving quality control, and reducing lead time.
Injection Molding Capabilities
SR Plastics operates injection molding presses ranging from 50 to 1,000 tons, enabling the production of everything from small, intricate components to large structural parts. Their in-house tooling, mold-maintenance, and process-engineering teams ensure consistent results across all material types and production volumes.
Beyond standard molding, SR Plastics supports a variety of secondary operations to complete parts in-house, including:
- Over-molding for multi-material components
- Sonic welding for secure, clean plastic joins
- Hot stamping and pad printing for durable part marking and branding
Integrated Machining & Molding Solutions
By combining SR Plastics’ injection molding with SR Machining’s precision CNC services, customers gain access to a fully integrated manufacturing solution. This collaboration enables production of injection-molded parts with critical machined features, as well as final assemblies that require both disciplines — all coordinated through a single supplier.
The result is simplified sourcing, consistent quality, and greater project efficiency from prototype to production.
