Increase throughput on your existing line — without the cost of a full replacement
Many FRP and composite plants in India are operating pultrusion lines that are five to fifteen years old. These lines were built when automation was expensive and resin control systems were largely manual. Today, the production demands of optical fibre cable manufacturers, rebar suppliers, and composite product plants require tighter tolerances, higher output speeds, and lower resin waste than older lines can consistently deliver.
JAE India provides structured line audit, retrofit, and upgrade services for existing FRP pultrusion lines — targeting the specific components that limit your production performance, without the capital cost and downtime of a full line replacement.
| Problem | Root Cause / Impact |
|---|---|
| Inconsistent rod diameter across runs | Die wear, temperature variation across die length, or puller speed fluctuation. |
| Rising resin consumption and waste | Manual resin bath without dosing control — excess resin usage and inconsistent wet-out. |
| Puller slippage during long production runs | Worn grip pads, incorrect caterpillar tension, or undersized puller for current production speed. |
| Surface defects — marks, cracks, porosity | Die surface wear, incorrect gel zone temperature, or contaminated resin bath. |
| High styrene / fume exposure at shop floor | No fume extraction or inadequate system — regulatory compliance issue. |
| Manual rod handling causing rod damage | No haul-off conveyor — rod surface scratched or bent during post-die handling. |
| Unable to produce new rod diameters | No die change capability or fixed creel configuration. |
| Low production speed compared to capacity | Outdated puller system, no servo control, or thermal curing bottleneck. |
Replacing an old manual or basic motor-driven puller with a servo-controlled caterpillar haul-off unit eliminates speed fluctuation — the primary cause of diameter variation and surface marks. Servo pullers also allow precise speed setting for each rod diameter without mechanical adjustment.
Consistent rod diameter, improved surface finish, 15–25% production speed increase
Replacing an open, manually filled resin bath with a temperature-controlled, metered dosing system reduces resin waste by 20–30% and improves wet-out consistency. Critical for OFC rod production where resin-rich zones are a reject cause.
Reduced resin consumption, lower reject rate, improved rod mechanical consistency
JAE India manufactures replacement dies for any pultrusion line — not only our own. If your current die is worn, has poor surface finish, or is producing incorrect dimensions, we supply a new die to your rod specification with improved zone length and polished bore surface.
Restored dimensional accuracy, improved surface finish, extended die service life
Older resistance heater systems consume significantly more power than modern ceramic band or infrared heater systems and respond slower to temperature corrections. JAE India installs energy-efficient heater systems with PID temperature controllers on existing die platens.
20–35% reduction in die heating energy consumption, faster temperature response, better zone control
Styrene vapour from open resin baths and glass dust from cut-off saws are the two primary occupational hazards in FRP plants. JAE India installs enclosed resin bath hoods with extraction, localised glass dust collection at the cut-off saw, and general shop floor fume extraction systems.
Regulatory compliance, reduced health exposure for plant operators
Automated conveyor systems between the haul-off unit and the spooling or cutting station prevent rod surface damage from manual handling and allow consistent delivery speed to the spooler.
Reduced rod damage, operator-free handling, smoother production flow
Replacing relay-based or manual control panels with a PLC-based automation system enables recipe storage for different rod diameters, alarm monitoring, production data logging, and remote monitoring capability.
Faster changeover between rod diameters, reduced operator dependency, production data visibility
| Condition | Recommended Approach |
|---|---|
| Line is structurally sound, specific components underperforming | Targeted retrofit — replace the limiting components only. Fastest ROI. |
| Line is producing consistently but speed is limited | Servo puller upgrade + automation panel — increases output without line stoppage. |
| Line cannot produce new rod diameters needed | New die set + creel expansion — often no structural change to existing line required. |
| Line is structurally worn, multiple failures | New line more cost-effective over 3–5 years than ongoing repair cost. JAE India supplies full replacement line. |
| Line needs to meet new environmental compliance | Fume extraction and dust collection retrofit — can be done without production shutdown. |
