Clear & Classified Whole-Machine Warranty Terms

1. Unified global warranty rule: The 12-month full machine warranty officially starts on the date of successful Site Acceptance Test (SAT) at the buyer’s factory, not the factory dispatch date. Ocean transit and installation periods will not occupy valid warranty coverage.
2. Classified component warranty breakdown (annexed to all JBD export contracts):
   • Heavy-duty transmission system (alloy gearbox, permanent magnet VFD main motor): 18-month full warranty
   • Screw & barrel assembly (38CrMoAlA nitrided / bimetallic composite): 12-month warranty against premature abrasion caused by factory material and processing defects; material counterfeiting triggers full free replacement plus liquidated damages
   • Siemens SMART LINE PLC, touch HMI, temperature control modules: 24-month original brand manufacturer warranty
   • Auxiliary equipment (haul-off machine, cutter, stainless cooling tank): 12-month warranty
   • Consumable wearing parts (cutting blades, filter screens, sealing rings): Exempt from free replacement; the supplier promises long-term preferential supply prices within 10 years after equipment delivery
3. Clear warranty exclusion clauses: Damage arising from improper manual operation, foreign hard material intrusion, unauthorized raw material formula modification and natural disasters shall not be covered by free repair or replacement services.

1.2 Raw Material & Component Authenticity Guarantee

1. Before FAT commencement, the supplier shall provide original steel mill test certificates (MTC), nitriding/hardness test reports and bimetallic surfacing metallographic inspection records for buyer review.
2. Binding penalty clause for material fraud: If third-party XRF element detection or ultrasonic thickness testing confirms the screw/barrel material grade is inconsistent with contracted standards (e.g. ordinary carbon steel replaces standard 38CrMoAlA, single thin nitrided parts falsely labeled as bimetallic), the supplier shall deliver a full new screw-barrel set free of charge within 15 working days and pay liquidated damages equivalent to 15% of the total contract amount.
3. Genuine electrical component commitment: All specified brands (Siemens, Schneider etc.) must be original brand new products; counterfeit electrical parts entitle the buyer to demand full free replacement of the whole electrical cabinet.

1.3 Production Performance & Energy Consumption Guarantee

1. Rated output tolerance: The stable hourly output measured during full-load FAT shall not be lower than 95% of the technical annex standard; any long-term insufficient output allows the buyer to deduct corresponding payment.
2. Finished product precision commitment: Wall thickness, outer diameter, sheet flatness error shall meet agreed standards (HDPE pipe ±0.08mm, optical PC sheet ±0.012mm), and the maximum scrap rate shall be clearly capped in the contract.
3. Power consumption limit: The power consumption per kilogram of finished products shall not exceed the indexed value; if actual power consumption exceeds the standard by over 10%, the buyer is eligible for price reduction compensation.
4. Long-term stable operation promise: No mechanical or electrical forced shutdown is allowed during the mandatory 72-hour continuous full-load FAT.

1.4 Global After-Sales Service Commitment (Critical for Overseas Importers)

1. Remote troubleshooting response rule: The supplier’s bilingual technical team must reply to fault videos and operational data within 4 working hours worldwide, offering 24/7 real-time video remote guidance via WhatsApp and WeChat.
2. Overseas engineer dispatch timeline: If remote adjustment cannot eliminate failures, multilingual technical engineers shall arrive at the buyer’s workshop within 15–30 working days according to regional division; all round-trip airfare, accommodation and labor costs shall be borne by the supplier within the warranty period.
3. Regional spare parts warehouse guarantee: Relying on Dunya Trading’s global layout, JBD sets localized spare stock points in the EU, GCC, Southeast Asia and Latin America; standard wear parts can be delivered within 3–7 working days without long 45+ day sea transit delays.
4. Free training obligation: The supplier provides pre-shipment online theoretical training and on-site full operational training during SAT commissioning, covering parameter adjustment, daily maintenance and common fault elimination, with signed training completion records retained.

1.5 Compliance Document & Logistics Liability Clauses

1. Complete certification delivery commitment: All required valid certificates including CE, GCC, ANATEL shall be delivered before shipment without extra hidden document fees.
2. Full technical data handover: Post-FAT, the supplier shall submit multilingual operation manuals, complete electrical CAD drawings and classified spare parts catalogs as attachment of the acceptance report.
3. DDP delivery liability clause (for cross-border orders): If the supplier provides DDP door-to-door shipping service, all customs detention, inspection fines and legal losses caused by incomplete supplier documents shall be fully compensated by the seller.

1.6 Breach of Contract & Remedial Liability Rules

1. FAT failure liability: If the first factory acceptance fails, the supplier shall finish all rectification free of charge within 10 working days and re-conduct the whole FAT at its own cost; repeated non-compliance allows the buyer to terminate the contract and claim full refund of all deposits.
2. Delivery delay liquidated damages: For each day of shipment delay beyond the agreed schedule, the supplier shall pay compensation equal to 0.15% of the total contract value.
3. Post-warranty spare parts price lock: Within 10 years after equipment delivery, the annual price increase of standard wearing parts shall not exceed 10%.

Part 2 Standard Factory Acceptance Testing (FAT) Protocols Required in Contracts

2.1 Pre-FAT Contract Stipulations

1. Advance notification requirement: The supplier shall issue a formal written FAT notice 15 working days after full line assembly is finished, so the buyer can arrange on-site inspectors or real-time remote video witnessing.
2. Three legal FAT witnessing modes clearly listed in the contract:
   • Option 1: Buyer’s professional technical inspector travels to JBD’s factory for full on-site witnessing (recommended for orders over $100,000)
   • Option 2: Authorized third-party institution (SGS / TÜV) on-site inspection; inspection fees borne by the agreed party
   • Option 3: Real-time live video witnessing (uninterrupted camera control by the buyer, pre-recorded footage is prohibited, suitable for medium & small budget equipment)
3. Test raw material obligation: The supplier must use the exact resin/formula specified by the buyer for all FAT production tests (virgin PE/PP, mixed PCR flakes, medical TPU etc.), generic substitute materials are not permitted.

2.2 Four-Stage Standard FAT Test Workflow (As Contract Annex)

Stage 1 Static Off-Load Visual & Assembly Inspection

1. Whole machine appearance audit: Frame welding quality, electrical cabinet IP protection grade, intact safety guards for rotating and high-temperature components.
2. Core component material cross-check: Match screw/barrel serial numbers with steel mill certificates, inspect nitriding or bimetallic surfacing appearance.
3. Full parts inventory: Count all main machines, auxiliary equipment, spare parts and tools against the signed packing list; FAT shall not start until all missing items are supplemented.
4. Electrical wiring inspection: Standardized wire layout, complete safety interlock circuits for feed doors, vent covers and emergency stop buttons.

Stage 2 2-Hour No-Load Dry Run Test

1. Power on the whole Siemens control system and confirm zero fault alarm codes on the touch HMI.
2. Test every emergency stop and safety interlock one by one; opening protective covers must trigger immediate host power cut-off.
3. Run extruder, haul-off and cutter at low, medium and high speeds without raw materials:
   • Record motor running current and overall vibration value (≤4.5mm/s complying with ISO 10816 standard)
   • Measure equipment noise at 1-meter distance (≤85dB)
   • Check gearboxes and bearings for abnormal vibration or metal squeaking noise
4. Independent heating zone test: Single zone temperature control error shall be controlled within ±1°C matching Siemens precision standard.

Stage 3 4-Hour Medium-Load Semi-Production Test

1. Feed the buyer’s designated raw material and adjust screw speed to 70% of rated maximum throughput.
2. Record melt pressure, barrel temperature, motor load and hourly output every 15 minutes.
3. Inspect extruded semi-finished pipes/sheets/strands to eliminate bubbles, black speck impurities and uneven wall thickness defects.
4. Verify automatic operation of supporting systems including online thickness detector, multi-stage vacuum tank and hydraulic screen changer.

Stage 4 Mandatory 72-Hour Full-Load Continuous Test (JBD Standard Clause)

1. The whole line operates at 100% contracted rated throughput for 72 consecutive non-stop running; only a 30-minute daily cleaning maintenance shutdown is allowed.
2. Hard pass criteria written into the contract:
   • No mechanical jamming, motor overload trip, circuit short-circuit or vacuum system failure during the whole test cycle
   • Average hourly output ≥95% of the technical annex index
   • All finished product dimensional tolerances fully meet agreed standards
   • Cumulative scrap rate below the contract-specified ceiling
   • All safety interlock and auto-protection functions remain effective throughout the test
3. Data archiving requirement: The supplier shall export complete 72-hour PLC production logs from the Siemens system as part of FAT document package.

2.3 FAT Acceptance Judgment & Rectification Rules

1. Full pass standard: All four-stage test items meet the technical annex requirements; both the buyer’s witness representative and JBD’s QC supervisor sign the official FAT Acceptance Report.
2. Minor single item non-conformity: The supplier completes rectification within 3 working days and only re-tests the unqualified single module.
3. Major performance/material defect (insufficient output, counterfeit screw material, frequent overload tripping): All four FAT stages shall be fully repeated after rectification, with all test costs borne solely by the supplier.
4. Consequence of repeated failure: The buyer reserves the right to terminate the sales contract and demand full refund of all advance deposits.
