LCP
Liquid crystal polymer flows into very thin molded sections and is used for precise, heat-resistant electronic components.
Review the thin features and their function together
For a small molded LCP component, show Aria the thin sections, contact locations and critical dimensions on the drawing. We help you discuss the selected grade and manufacturing requirements against the part’s function. Include reinforcement and any required electrical or flame-rating documentation in the same review.

Compatible manufacturing processes
Selection requirements
- Injection molding
Thin-wall and precision injection molding. The supplied drying reference is 150°C for four hours; follow the selected grade datasheet. Gate position and flow direction are critical. Keep weld lines away from loaded areas and confirm reinforcement, drying and flame-rating requirements.
Advantages and considerations
Advantages
Excellent melt flow, low molding shrinkage and thermal expansion, low moisture uptake and useful dielectric behavior. Some designs use walls below 0.3 mm.
Material limitations
Strong flow-direction dependence and weak weld lines constrain mechanical design. Unfilled grades can be brittle; colors and appearance finishing are limited.
How Aria supports your project
Help choosing a material
Compare materials for the loads, temperature and environment your part will face.
Design feedback before production
We review tool access, geometry and material choice before manufacturing.
Inspection to your drawing
Dimensional checks and inspection reports for the critical features on your drawing.
Compatible surface finishes
Selection requirements
- Laser engraving
Gate position and flow direction are critical. Keep weld lines away from loaded areas and confirm reinforcement, drying and flame-rating requirements. Laser marking; circuit metallization is possible with suitable MID/LDS material and process selection. Decorative painting is less common.
Applications
Typical applications
Precision connectors, surface-mount components, high-frequency antenna parts, optical modules and thin-wall electronics.
