Choose the configuration
What to resolve before selecting this equipment
Match the formulation
Provide component technical and safety data, viscosity at operating temperature, mix ratio and permitted handling conditions. Request written compatibility of the wetted parts and seals.
Size the metering duty
Define minimum, normal and maximum resin demand for the proposed profiles. Request stable delivery and ratio performance at each agreed operating point.
Define the injection interface
Agree the connection to the impregnation chamber, permissible backpressure, start/stop sequence and ownership of line interlocks before finalizing the assembly.
Evidence and purchasing requirements
What the YH-2700 manufacturer reference establishes
Huafan identifies the YH-2700 as a two-component polyurethane injection machine for composite pultrusion, filament winding and molded products. The manufacturer brochure describes digital control with electronic adjustment of mix ratio and output and lists a 1:3–3:1 ratio range.
The brochure gives power, compressed-air, hose, size and weight references. Resin delivery is selectable, with no numerical output range or resin injection pressure stated. Request the operating envelope for your formulation and agree the pump arrangement, injection connection, controls and acceptance checks in the quotation.

Production workflow
Review the dosing and injection process
Use these stages to define responsibilities, interfaces and the evidence needed at handover.
- 01
Approve the material package
Review the formulation supplier’s handling instructions and agree conditioning, storage and replenishment requirements.
- 02
Set and verify metering
Agree a component collection or equivalent verification method, calibration records and the target ratio before the profile trial.
- 03
Connect mixing and impregnation
Define the delivery path and injection chamber interface, then verify the sequence with the pultrusion-line supplier.
- 04
Trial, stop and restart
Use the agreed materials to demonstrate production, interruption and restart. Document the cleaning procedure, waste handling and remaining adjustments.
Scope of supply
Define the supply package and its options
Request an itemized quotation against these lists. A catalogue description does not confirm that every item is included.

FAQ
Questions buyers ask
- Is this a complete polyurethane pultrusion line?
- No. The PU resin metering and mixing system covers a resin-handling stage. Pulling, heated tooling, reinforcement feed, cut-off and the injection chamber must each be assigned a supply responsibility in the quotation.
- Can the YH-2700 be used with our resin formulation?
- Submit the component data, required ratio, viscosity, handling conditions and resin demand. Request written compatibility and an agreed material trial for the proposed two component resin injection system; the catalogue model name alone does not establish suitability.
- How are the YH-2700 operating specifications agreed?
- Huafan provides the configuration-specific specification for the proposed formulation and line interface. Agree the output units, pressure, temperature and heating requirements before approving the purchase specification.
- Who supplies this equipment and carries the warranty?
- The supplier is Huafan Technology, 上海华帆机电科技有限公司 in Shanghai, China. Confirm Huafan’s exact legal warranty entity, warranty terms and service scope in the quotation, alongside the contracting party and exporter of record. Henan Zhongsheng is not identified as the manufacturer of this equipment.
- What should be settled before ordering?
- Agree the signed configuration, supply boundaries, electrical design, material trial and FAT criteria. The quotation must state payment, lead time, warranty responsibility and any commissioning or training services. Request a Huafan supplier-document review or audit as part of the enquiry.
