Buyer's Responsibilities

• Supply and connect the power cable to the equipment electrical cabinet per public utility conditions; connect the required grounding cable to the designated connection point on the equipment.
• Construction of equipment foundations (including core drilling, PVC conduit, etc.), pipelines, embedded parts, and grounding systems.
• Overhead crane / mobile crane/forklift and other equipment required for unloading, positioning, and installation/commissioning at the buyer's site.
• Compressed air, electricity, and auxiliary materials for equipment commissioning, delivered to the designated location.
• Trial-run materials for commissioning were delivered to the designated location.
  
  

Delivery, Acceptance & Inspection

• Inspection standards: this Technical Agreement and the manufacturer's applicable national standards.
• Acceptance and inspection shall be carried out by both parties at the supplier's production site in accordance with the Technical Agreement; equipment is shipped after passing inspection.
• Full performance testing shall be conducted at the end user's site; both parties shall perform item-by-item acceptance per the Contract and Technical Agreement; an Acceptance Report shall be signed by both parties upon passing.

Main Technical Parameters(Stacking Machine)

No.	Performance Parameter		ZXD-440
1	Lamination Specifications	Width	50–440 mm
		Thickness	0.18–0.35 mm
		Side Limb Length	380 mm (corner-to-corner) – 2500 mm (tip-to-tip)
		Yoke Length	380 mm (corner-to-corner) – 2500 mm (tip-to-tip)
		Center Limb	380–2060 mm
		Max Core (L×W×H)	2500×2500×600 mm
3	Stacking Accuracy	Same-grade Length Direction	≤±0.5 mm
		Same-grade Width Direction	≤±0.5 mm
		Same-grade Thickness Error (stacked by sheet count)	≤1 mm
	Note:	Core accuracy is simultaneously affected by sheet cutting accuracy and stacking accuracy. Manual reshaping after stacking is required to achieve higher precision. If the shutdown for reshaping due to the buyer's higher precision requirements reduces equipment productivity in normal production, responsibility lies with the buyer and is unrelated to the supplier's equipment.
8	Stacking Cycle Time		Approx. 60 sheets/min Acceptance standard core: Width 260 mm; Length 1000 mm
9	Air Supply	Pressure	≥0.6 MPa
		Total Air Consumption (energy-saving vacuum generator; reduces compressed air costs)	≤0.6 m³/min
10	Equipment Noise		≤80 dB
11	Equipment Color		Factory standard: Main color: Light Grey 7035, Sky Blue 5015; Moving parts: Signal Yellow 1003. Custom colors available.

Installation, Commissioning, Training, After-Sales Service & Warranty

Installation, Commissioning & Training	The supplier's engineers provide free on-site training on operation, maintenance, and upkeep.	Time required: Installation and commissioning are generally completed within 2 weeks. Personnel training (equipment operators and maintenance technicians) begins simultaneously with installation and ends upon completion of installation.
After-Sales Service	If equipment problems arise, the supplier dispatches personnel for repair and provides basic troubleshooting and daily maintenance guidance.
	Daily Response Time	Response within 24 hours. On-site arrival: same day within the supplier's province; next day for other provinces.
	Holiday Response Time	Response within 24 hours. On-site arrival during holidays if the buyer has on-duty personnel.
Note:	1. For faults requiring on-site service, arrival is generally within 48 hours; phone resolution is preferred where possible. 2. The supplier provides lifetime service; discounted spare parts, components, and technical support continue after the warranty period. 3. If the buyer defaults on payment after acceptance, the supplier makes no warranty commitment.
Warranty Period	12 months from the date of final acceptance. During the warranty period, if a fault arises due to equipment quality issues or correct operation per the supplier's procedures, the supplier provides free parts and repair at no cost to the buyer. If a fault arises due to failure to follow operating procedures or overloading, the supplier promptly resolves the fault and charges only the component cost.
