A caterpillar pultrusion machine pulls the composite profile between continuous tracks. Haoli publishes three configurations with different pulling ratings, clamping windows and contact lengths. Select the track contact, grip pressure and profile support around wall thickness and surface requirements, then verify the proposed production conditions in a material trial.

Manufacturer: Nanjing Haoli Hydraulic Equipment Co., Ltd.
Sales contact: pultrx, Shanghai, China

SELECTION
- Start with the product drawing: Send section dimensions, material data, reinforcement layout and output targets. Agree the gripping surface, die interface and acceptance samples before choosing the configuration.
- Define each supply boundary: Identify who supplies the machine, die, reinforcement feed, resin handling and downstream stations. Record connection details, control interlocks and commissioning responsibilities.
- Agree a material trial: Specify trial materials, operating points, measurement methods and pass/fail criteria. A catalogue rating alone does not establish finished-product output or conformity.

Manufacturer reference and purchase requirements
Haoli lists continuous-track pultrusion equipment with three pulling and gripping configurations. The model designations reproduced here follow the manufacturer table; identify the exact machine on the signed configuration sheet.

Compare the profile contact area and grip force together. Specify acceptable marks, wall deformation and support through the cut-off station, then demonstrate them with the intended section and resin.

APPLICATIONS TO REVIEW
- Constant-section FRP profiles suitable for continuous-track gripping
- Thin-wall or surface-sensitive profiles subject to a grip and material trial

PROCESS TO REVIEW
- Review drawings and materials: Approve the proposed equipment layout, tooling interfaces, formulation and reinforcement package.
- Set up the production path: Check reinforcement alignment, impregnation, heating, gripping and cut-off against the agreed supply list.
- Verify the proposed operating points: Record speed, temperatures, pulling behavior and sample condition using the agreed trial materials.
- Document acceptance and handover: Demonstrate stops, restarts and interlocks. Record adjustments, training, spare parts and unresolved items.

CORE SCOPE TO SPECIFY
- Machine frame, pulling assembly and controls: confirm the configuration and supplied-item list
- Die support and heating: identify zones, power, control and mounting interfaces
- Machine drawings, operating instructions and agreed factory acceptance records

OPTIONS AND SERVICES TO PRICE SEPARATELY
- Profile-specific dies, mandrels, preform guides and clamp inserts
- Creels, resin handling, injection equipment, cut-off and run-out stations unless listed in the quotation
- Trial resin and reinforcement, additional product trials and qualification testing
- Site utilities, local electrical adaptation, installation, commissioning and training
- Packing, freight, spare parts and third-party witnessing

RFQ INPUTS — complete these before requesting a quotation
- Product drawings, dimensions, tolerances and annual order or production plan
- Resin and reinforcement data, required surface finish and applicable product tests

WARRANTY PARTY
Nanjing Haoli Hydraulic Equipment Co., Ltd.; responsible legal entity, term, coverage and support agreed in quotation.

Nanjing Haoli Hydraulic Equipment Co., Ltd. factory audit and third-party inspection: agree access, scope, provider, evidence and costs in the quotation. Contracting legal entity and exporter of record must also be agreed.

COMMERCIAL ITEMS TO CONFIRM
Applicable performance and destination requirements; lead time in working days; payment milestones; warranty party, term and exclusions; packing, Incoterm and delivery destination. For equipment, include plant power and spare parts.

QUESTIONS
Who manufactures the equipment and carries the warranty?
Nanjing Haoli Hydraulic Equipment Co., Ltd. is the equipment supplier. pultrx coordinates the sales enquiry. Confirm the legal contracting party, exporter of record, warranty entity, coverage and service scope in the quotation. Henan Zhongsheng factory certificates and warranty terms do not qualify Haoli equipment.

Does the catalogue price include a complete production line?
Request an itemized quotation. The machine, tooling, reinforcement feed, resin handling, cut-off, site work and services need individual supply responsibilities. A catalogue model does not establish the complete package.

How are production performance and acceptance agreed?
Use your drawing, formulation and reinforcement for the equipment review. Agree the trial operating points and product checks before purchase; machine acceptance does not establish finished-product certification.
