Line Equipment We Manufacture
Pultrusion machines are vital for making fiber-reinforced composites. These are specifically fiber-reinforced polymers (FRP). The efficiency and quality of the pultrusion process depend on various key components. They must work together seamlessly. Below are the primary components of pultrusion machines we can provide.
Fibers are usually unwound from creels or rolls. Our system must ensure proper tension and alignment. This will prevent entanglement or breakage during processing.
We provide three different types:
- Dip Bath: Fibers are submerged in a resin bath for thorough saturation.
- Straight Through Bath: Allows for continuous flow through the resin.
- Resin Injection System: Injects resin into the fibers. It ensures even distribution and minimizes waste.
It used to shape the resin-soaked fibers before the die. It brought them close to their final profile. Our component aligns the fibers for curing. It removes excess resin, too.
The die can be a one-piece or split cavity type. It often has multiple heating zones to cure the resin evenly as it passes through.
We provide two types of pulling systems. They draw the cured composite profile through the die.
- Hydraulic Reciprocating Puller: It uses alternating grips to pull the profile. It is suitable for high pull forces.
- Caterpillar Puller: A system that grips and pulls the profile through the die. It’s ideal for low pull speeds and repetitive tasks.
It cuts the continuous pultruded profile into specified lengths after curing. Our cutter runs with the pulling mechanism. It may use an abrasive or diamond wheel. It can include coolant systems to reduce dust and heat while cutting.
Our advanced pultrusion machines often have automated control systems. They manage temperature, resin impregnation, pulling speed, and tension. This ensures consistent product quality.
Built for small cross-section profiles, lab trials, and pilot runs — the line where you validate resin systems and molds before committing to full-scale production. We match the machine to your trial mold and stay on the line with you until the first qualified profile comes off the die.
Suited to small-batch profile production: electrical insulation parts, ladder rails, and light structural sections that need steady quality without a large equipment footprint. Ships with die-adaptation support, so your existing molds can be re-fitted and process-tuned on our floor before dispatch.
Handles medium cross-section profiles — cable trays, handrail systems, and standard construction sections — in continuous daily production. During commissioning our engineers tune pulling speed and die temperature zones to your specific resin system, on site or remotely.
A batch-production line for construction profiles: window and door sections, structural beams, and fencing profiles run at stable shift output. Includes mold design review and operator training, so your crew can hold tolerances without our supervision after handover.
A 20-ton class line for larger structural profiles and higher-resistance molds, sitting between standard construction sections and heavy industrial sections. We size the clamping layout and die heating zones to your largest mold, and provide commissioning support through first-article approval.
Our high-tonnage hydraulic line for large cross-section and thick-wall profiles, built for continuous duty on heavy structural production programs. Delivered with full mold adaptation, process parameter tuning, and on-site commissioning until the line holds rated output.

For process fundamentals, see our pultrusion process guide. For selection methodology, see how to choose a pultrusion machine.
Fiberglass Pultrusion Machine Configurations
Most export orders are fiberglass pultrusion machines — lines that run E-glass roving and mat into GFRP profiles such as rebar, tubes, channels, and grating. A fiberglass pultrusion machine typically pairs a multi-position creel with a polyester or vinyl ester bath, a chrome-plated heated die, and a caterpillar puller sized to the profile envelope.
For glass-fiber production we configure higher roving counts, wider preform guides, and multi-zone die heating as standard; carbon or hybrid capability can be added to the same frame when your product mix expands. Share your target profiles and we will confirm whether a 6–12 ton or 20–30 ton fiberglass line fits your output plan.
Production Line Modules We Supply
Turnkey pultrusion plants combine several subsystems. IncomePultrusion can deliver a full line or standalone upgrades:
- Fiber creel & roving rack — tension-controlled unwinding for glass, carbon, or hybrid reinforcements
- Resin mixer & impregnation bath — polyester, vinyl ester, or epoxy batch mixing and fiber wet-out
- PU injection unit — closed-box injection for polyurethane pultrusion where applicable
- Preforming & guidance — alignment before the heated cavity
- Heated pultrusion die — tool-steel cavity engineered to your cross-section
- Traction puller — hydraulic reciprocating or caterpillar puller matched to pull force and line speed
- Flying cut-off saw — length synchronization with the pulling mechanism
- Control system — PLC or relay control of temperature zones, pull speed, and safety interlocks
YLJ Series — Reference Capacity Range
Our hydraulic pultrusion machine family (YLJ series) covers common export configurations. Final specs are confirmed per project:
- Models: YLJ-6T, YLJ-8T, YLJ-12T, YLJ-15T, YLJ-20T, YLJ-30T
- Pulling / clamping force: 6–30 ton (model dependent)

Share your profile drawing, fiber architecture, resin type, and annual volume — we recommend a frame size and quote motor, heating, and auxiliary scope.
How to Select the Right Line Configuration
Procurement teams should align machine scope with product and factory constraints:
- Define the profile — cross-section, wall thickness, tolerances, and surface finish targets
- Confirm materials — glass, carbon, or hybrid rovings; polyester, vinyl ester, epoxy, or PU resin system
- Set output targets — line speed, daily meters, and shift pattern
- Match pull force — larger sections and faster cures require higher traction and die heating capacity
- Plan facility interfaces — line length, ceiling height, power supply, ventilation, and resin storage
- Bundle dies & auxiliaries — new lines often include custom dies, mixers, and cutters in one turnkey package
We support feasibility review before order placement so the quoted line matches your shop layout and product mix.

Frequently Asked Questions
What is the energy consumption of a typical pultrusion machine?
A standard pultrusion machine consumes between 25-45 kWh during operation, depending on profile size and production speed. Larger machines with higher pulling capacities may consume 45-80 kWh. Energy-efficient models can reduce consumption by 15-25% compared to older equipment.
How often does the die need maintenance or replacement?
With proper operation, pultrusion dies typically last 100,000-500,000 meters of production before requiring significant maintenance. Chrome-plated dies last 2-3 times longer than standard steel dies. Regular cleaning and lubrication every 8-12 hours of operation extends die life significantly.
What are the staff requirements to operate a pultrusion machine?
Most pultrusion operations require 1-2 operators per shift for standard lines. One operator can often manage multiple lines once production is stabilized. Proper training takes approximately 40-80 hours for basic operation and an additional 80-160 hours for advanced troubleshooting and parameter optimization.
How do I determine the correct pulling speed for my application?
Optimal pulling speed depends on multiple factors including:
- Resin cure kinetics (gel time and exotherm profile)
- Die length and temperature profile
- Wall thickness of the profile (thicker = slower)
- Fiber type and content
Start at the lower end of the recommended range (typically 0.2-0.3 m/min) and gradually increase while monitoring cure quality.
What tolerance specifications can be achieved with pultrusion?
Modern pultrusion equipment can consistently achieve:
- Linear dimensions: ±0.2mm for dimensions up to 100mm
- Angular dimensions: ±1° for standard profiles
- Wall thickness: ±0.1mm for thin walls, ±0.2mm for thicker sections
- Surface finish: Ra 0.8-3.2 μm depending on die quality
How do I troubleshoot common parameter-related issues?
The most common parameter issues can be resolved by following this diagnostic sequence:
- Check die temperature profile across all zones
- Verify pulling speed is appropriate for material and profile thickness
- Examine resin bath temperature and catalyst mix
- Inspect fiber tensioning and guidance system
- Confirm pulling force is within machine specifications
