EV Battery Tray HP-RTM Molding Solution
HP-RTM processing for composite EV battery enclosures. The reference project reports 40% lower tray component weight against its aluminum baseline; structural, electrical and battery-system safety are validated separately.
Structural Composite HP-RTM Solutions for EV Battery Enclosures
Haifeng HP-RTM equipment coordinates resin metering, injection, tool vacuum and temperature control for composite battery trays. The related project reports 40% lower tray weight than its welded aluminum assembly baseline. That component comparison is not a universal reduction for every composite design or for total vehicle weight. Flame-retardant epoxy or polyurethane and glass or carbon reinforcement are selected for the laminate. UL94 V-0 applies to the tested material specimens; it does not establish thermal-runaway containment. Corrosion behavior, impact response, leakage and electrical insulation are evaluated for the complete material, geometry and interfaces. Carbon reinforcement can conduct electricity, so electrical safety requires the corresponding enclosure and battery-system validation.
Laminate-Specific Electrical Insulation
Electrical insulation is evaluated for the complete laminate, coatings and interfaces. Carbon reinforcement can conduct electricity; the selected construction requires application-specific electrical testing.
Reference Impact Condition: 150 J
The supplied application reference describes a 150 J steel-ball impact condition. The specimen construction, impact location and acceptance criteria are tied to the qualified part; this does not establish complete battery-system protection for every enclosure.
Haifeng delivers the complete processing scope—from high-pressure composite injection skids and vacuum management to optional heavy hydraulic presses—enabling EV battery pack suppliers to scale safe, lightweight enclosure manufacturing.Concept illustration — not a photograph of delivered equipment or a customer installation.
Composite Battery Tray HP-RTM Production Workflow
A synchronized four-stage workflow delivering high-integrity, fire-resistant composite battery enclosures.
Preform Preparation & Vacuum
Multi-layer continuous fiber preforms are seated into the open tool; the press closes and a deep vacuum of <10 mbar is drawn
High-Pressure Resin Injection
The HP-RTM machine injects flame-retardant resin at extreme pressures, driving rapid wet-out across wide 2-meter battery tray spans
Heated Consolidation & Cure
Multi-zone dynamic TCU units hold precise mold curing temperatures, crosslinking the composite rapidly within 4 minutes

Key Engineering Advantages
For EV Battery Tray Composite HP-RTM Molding Line, assess material compatibility, process control, equipment interfaces and changeover needs against your production brief.
Reference Tray Weight Reduction
The related project reports 40% lower tray component weight versus its welded aluminum baseline. A different design requires its own mass comparison; driving range is not inferred from this value.
Construction-Specific Electrical Validation
Electrical properties depend on the reinforcement, laminate, coatings and interfaces. Carbon reinforcement can conduct electricity; the complete construction requires electrical testing.
UL94 V-0 Material Reference
The rating describes tested material specimens. Thermal-runaway containment, structural integrity and complete battery safety require separate application-specific validation.
Environment-Specific Corrosion Evaluation
Resistance to road salts, moisture and cleaning chemicals is assessed for the selected material and interfaces. A universal lifetime corrosion guarantee is not implied.
