How do I set pull speed without undercuring the profile?

Pull speed must leave the profile in the die long enough to reach full cure at the running temperature. Divide the heated die length by the required cure dwell to get the maximum safe speed. The Pull Speed and Cure Die Dwell calculators work together on this, and the Resin Gel Time Margin calculator warns when a faster rate pushes gelation too close to the die exit.

What fiber volume fraction should a pultruded profile target?

Structural pultrusions commonly run 50 to 70 percent fiber by volume depending on the shape and load requirements; higher fractions raise stiffness and strength but need careful wet-out. The Fiber Volume Fraction and Glass Loading calculators let you set reinforcement to hit mechanical targets while the Resin Bath Consumption calculator confirms the matrix keeps up.

How do I calculate resin consumption for a pultrusion run?

Resin draw equals the profile's cross-sectional resin volume times pull speed times run time, plus bath losses. The Resin Bath Consumption calculator estimates this from profile geometry and fiber fraction, and Resin Cost Per Foot turns it into money. Pair it with Fiber Cost Per Foot to get the full material cost feeding your quote.

What does splice loss cost me in a continuous run?

Every roving or mat splice can force a slowdown or create a weak section that gets cut out, costing both feet and downtime. The Splice Loss calculator quantifies the length and time lost per splice, and combined with Scrap Length Cost and Cut Length Yield it shows how much finished profile you actually keep from each spool of reinforcement.

How is pultrusion line OEE calculated?

Line OEE multiplies availability, performance, and quality: uptime against schedule, actual pull speed against rated, and good feet against total feet. The Line OEE calculator combines these, drawing on Line Throughput and Die Utilization so you can see whether lost output comes from downtime, running slow, or scrapping out-of-spec profile.

How do I price a pultruded profile per foot or per meter?

Sum resin, fiber, heater energy, and labor per length, then add scrap and margin. The Profile Cost Per Meter and Quote Price calculators roll up Resin Cost Per Foot, Fiber Cost Per Foot, Heater Energy Cost, and Labor Per Foot, while Profile Weight Per Foot ties material draw back to the cross-section so the cost matches the shape you are quoting.

Manufacturing calculator category

Pultrusion & Continuous Composite Profiles calculators

This category covers the process math for pultruding continuous fiberglass and carbon profiles such as rebar, gratings, window lineals, and structural shapes. It is built for line operators, process engineers, and estimators who set pull speed, dial in fiber loading, and cost profiles by the foot. Use it to balance cure quality against throughput before running the line.

Best calculators in this category

Pull Speed: Pull speed is the linear rate at which a pultrusion machine draws impregnated reinforcement through the heated forming die, and it governs everything downstream: cure state, surface finish, and output.
Fiber Volume Fraction: Fiber volume fraction is the ratio of reinforcement to total composite volume, and in pultrusion it directly sets the profile's stiffness, strength, and dimensional stability.
Resin Bath Consumption: Resin bath consumption is the volume of catalyzed resin a pultrusion line draws to fully wet out the reinforcement for a run.
Cure Run Time: Cure die dwell is the time reinforcement spends in the heated forming die reaching full cross-link, and it caps how fast a pultrusion line can safely run.
Profile Weight Per Foot: Profile weight per foot is the linear mass of a pultruded FRP profile, the pounds of fiberglass, carbon, or vinyl-ester composite in every running foot of a rod, channel, angle, or custom die shape.
Line Throughput: Line throughput is how many pultruded profiles a die and pulling system actually deliver per hour once uptime and yield losses are counted.
Scrap Length Cost: Scrap length cost puts a dollar figure on the feet of pultruded profile that never ship, startup transients, off-color runs, out-of-tolerance sections, and the lead-in scrap around every die change.
Resin Cost Per Foot: Resin cost per foot isolates the single largest consumable in pultrusion, the polyester, vinyl-ester, or epoxy system, plus catalyst and fillers, spread across every running foot of profile.
Fiber Cost Per Foot: Fiber Cost Per Foot tells a pultrusion line what the glass or carbon reinforcement actually costs for every linear foot of profile it pulls.
Heater Energy Cost: Heater Energy Cost captures what it costs to keep a pultrusion die at cure temperature while the line runs.
Splice Loss: Splice Loss measures how much finished profile you lose to defects and scrap around roving splices, the joints where a fresh package of glass or carbon is knotted or overlapped onto a running strand.
Die Utilization: Die Utilization shows what share of your pultrusion tooling inventory is actively earning versus sitting idle on the rack.
