Resin Transfer Molding (RTM) Services
Precision-engineered thermoset composite components manufactured using closed-mold Resin Transfer Molding for structural strength, dimensional accuracy, and repeatable performance.
High-Performance Closed-Mold Composite Manufacturing
Resin Transfer Molding (RTM) is a closed-mold composite manufacturing process used to produce structurally reinforced thermoset components with consistent quality and dimensional precision.
At Zehrco-Giancola Composites, we combine engineered fiber preforms with carefully controlled resin injection systems to manufacture complex composite parts that meet demanding mechanical, environmental, and structural requirements.
Our vertically integrated process ensures repeatability, surface quality, and optimized performance from prototype through production.
How Our R&D Lab Supports RTM
Engineered Materials & Process Control
Our in-house Research & Development and testing laboratory supports RTM projects through:
-
Resin Flow & Cure Optimization – Development of resin systems engineered for proper flow, fill, and cure within closed molds.
-
Fiber Architecture Engineering – Controlled reinforcement design to meet structural load requirements.
-
Mechanical & Environmental Validation – Testing for strength, impact resistance, temperature performance, and long-term durability.
-
Process Refinement – Continuous improvement of injection parameters to reduce variability and enhance repeatability.
This integrated approach ensures structural integrity before full production begins.
Advanced Thermoset Resin Systems
Our Resin Transfer Molding capabilities are supported by advanced thermoset systems, including:
-
Vinyl Ester Resins – Corrosion resistance for harsh industrial environments
-
Polyester Resins – Cost-effective structural performance
-
Epoxy Resins – Superior strength and adhesion
-
Phenolic Systems – Fire resistance and high-temperature stability
By pairing engineered fiber reinforcement with optimized resin systems, we produce RTM components that meet strict mechanical and environmental performance standards.
