FRP (Fiberglass Reinforced Plastic) grating mold machines are specialized equipment designed for the production of FRP gratings, which are widely used in various industries due to their corrosion resistance, lightweight, and high strength properties. These machines typically involve a process that combines resin impregnation, fiberglass reinforcement, and a molding procedure to create durable and long-lasting FRP grating panels.
Core Components of FRP Grating Mold Machines
FRP Grating Mold Platen Assembly
Material: Hardened steel.
Design: Interchangeable mold inserts for different grating patterns (e.g., 38x38mm, 50x50mm mesh).
Surface Treatment: Anti-adhesion coatings to prevent resin sticking.
Heating System
Methods:
Water Circulation: Uniform heating (40–55°C) for large platens.
Hydraulic Press System
Pressure: 100–500 tons (depends on grating size/resin type).
Speed: Adjustable closing/opening cycles (20–90 sec per cycle).
Resin Injection & Mixing Unit
Resin Types: Vinyl ester, polyester, or phenolic.
Metering System: Precision gear pumps for resin/hardener (ratio 100:1 to 100:2).
Mixing Head: Static or dynamic mixer for bubble-free dispersion.
Material Handling
Fiber Delivery: placement of glass fiber roving/mat into molds.
Demolding: Ejector pins/air blasts for part release.
Production Workflow
Mold Preparation → 2. Fiber Roving Layup → 3. Mold Closing → 4. Resin Injection →5.Curing (Heat + Pressure) → 6. Demolding → 7. Trimming & Finishing.
Pro Tips for Buyers
Material Testing: Validate mold coatings against resin adhesion (e.g., ISO 8295).
Post-Cure Handling: Integrate conveyor cooling/UV stabilization tunnels.
Local Support: Choose suppliers with regional technical service teams.
Future-Proofing: Modular designs allow upgrades (e.g., adding IoT sensors).
💡 Expert Insight: For fire-rated phenolic grating, opt for closed-mold machines with vacuum-assisted resin injection to minimize voids and ensure UL94 V-0 compliance.
When considering the purchase of an FRP grating mold machine, it’s important to evaluate your specific production requirements, budget constraints, and potential for future scalability. Engaging with reputable manufacturers who provide reliable equipment along with strong customer support can significantly contribute to the success of your FRP grating production line.
