Pultrusion machines, sized from your profile drawing.
A pultrusion machine pulls resin-impregnated fiber through a heated steel die and cuts the cured profile to length. Henan Zhongsheng builds hydraulic reciprocating machines, caterpillar machines and multi-line GFRP rebar lines, and runs the same designs in its own profile production.

FAQ
Pultrusion machine basics
- What is a pultrusion machine?
- A pultrusion machine continuously pulls resin-impregnated fiber through a heated steel die, where the resin cures into a constant cross-section profile. It consists of a mold table with die heating, a puller (hydraulic reciprocating clamps or caterpillar tracks), a control system and a cut-off saw. Creels and a resin bath or injection box sit upstream.
- How much pull force do I need?
- Pull force depends on the die length, cross-section perimeter, fiber content, filler and line speed. Small rods and tubes run on 50–100 kN machines; structural beams and sheet pile need 300–500 kN. The factory sizes the machine from your drawing.
- Is the machine supplied with a die?
- No. Dies are profile-specific and quoted separately, usually together with the machine. See the pultrusion dies section.
- Who is the manufacturer and who do I contract with?
- Henan Zhongsheng Composite Material Co., Ltd. builds the machine and is the warranty party. The Shanghai export company is the contracting party and exporter of record. Both are named on every quotation.
