Cycle Time: Competitive with thermoplastics
Material Cost: Slightly higher, offset by performance gains
Lifecycle Durability: Superior under harsh conditions
Case Study: Thermoplastic to Thermoset Conversion for High-Stress Components
Company: Plastic Injection Molding Service in Glendora, CA
Industry: Automotive & Aerospace
Original Material: Thermoplastics (e.g., nylon, ABS)
Converted To: Thermoset epoxies and phenolics
Challenge
Components like water pump shafts and aircraft antenna housings were failing under:
• High thermal loads
• Chemical exposure
• Mechanical stress
Thermoplastics couldn’t maintain dimensional stability or resist degradation in these environments.
Conversion Strategy
Plastic Injection Molding Service in Glendora, CA transitioned to Thermoset materials:
• E2738 epoxy for pump shafts
• FM4004 Phenolic for filter cages
• FM4007 Thermoset for antenna housings
These materials offered:
• Superior heat resistance
• Chemical durability
• Molded-in strength with no post-processing
Results
• Reduced failure rates and warranty claims
• Improved mold precision and eliminated secondary machining
• Lower lifecycle costs due to enhanced durability and fewer replacements
Conclusion
Thermoset plastics are not just an alternative; they’re a strategic enabler for drone manufacturers aiming to optimize performance, reliability, and cost. Their unique properties position them as a material of choice for next-gen aerial systems.
