Subject: Sharing our Proposal Strategy for the Client (Please review for Quotation)

Dear Kathy,

To help you prepare the Budgetary Quotation, I am sharing the Draft Proposal that I will present to my end-customer today.

This document explains WHY we selected the "Double Intensifier Pump" and "Top & Bottom Cutting" system instead of Laser.

Please read this carefully. It will help you understand our sales strategy and the technical requirements.

[Key Points of our Proposal]

1. Safety: Emphasizing that Laser is dangerous (Explosion risk) vs. Waterjet is Safe.

2. Speed: "Top & Bottom Cutting" creates an Air Vent, making drainage much faster.

3. Durability: "Double Intensifier Pump" ensures 24-hour non-stop operation (Redundancy).

Please refer to the detailed proposal below and reflect these specifications (especially the Double Intensifier Pump model HEAD42037Z-B02 ¹) in your Quotation.

Best regards,

Sang Gyeong Kim

[PROPOSAL] Automatic Waterjet Cutting System for Lead-Acid Battery Electrolyte Drainage

Proposed by: More Cutting Technology Co. (HEAD Waterjet Korea)

Date: December 17, 2025

1. Project Overview

• Target: Recycling process for imported Waste Lead-Acid Batteries.

• Capacity: 500 tons/day (Approx. 3,000 units).

• Goal: To establish a fully automated pre-treatment process for draining sulfuric acid (electrolyte).

• Key Challenges:

  1. Safety: Preventing explosion risks from residual Hydrogen gas.

  2. Productivity: Ensuring high-speed drainage and 24-hour non-stop operation.

2. Proposed Solution: Double Intensifier & Top-Bottom Cutting System

We propose an optimized system that combines "Hydro-dynamic Drainage Efficiency" with "Operational Stability."

2.1. Core Technology: Top & Bottom Simultaneous Cutting

To overcome the slow drainage caused by the vacuum effect in bottom-only drilling.

• Configuration: One High-Pressure Pump splits water flow to 2 Customized Cutting Heads².

• Mechanism:

  • Bottom Head: Creates the drain hole.

  • Top Head: Creates the "Air Vent."

• Benefit: The Air Vent allows air to enter, breaking the vacuum lock and forcing the acid to drain out explosively fast, maximizing production speed.

2.2. Core Equipment: Double Intensifier Pump (Redundancy System)

To guarantee zero downtime for the 24-hour factory.

• Model: HEAD42037Z-B02 (37kW / 50HP Double Intensifier Type)³.

• Feature: Built-in Two Intensifier Engines (One ready, one on standby)⁴.

  • 1 Working / 1 Standby: If Engine A needs maintenance (seal change), just switch the valve, and Engine B takes over immediately⁵.

  • Effect: No production stoppage. No need to buy a separate spare pump unit.

3. Technical Comparison: Waterjet vs. Laser

Why Waterjet is the ONLY safe choice for this project.

3.1. Chemical Safety (Hydrogen Explosion Risk)

Waste batteries inevitably contain Hydrogen gas ($H_2$) generated by electrolysis inside the battery case.

• Chemical Reaction:

  $$2H^+ (aq) + 2e^- \rightarrow H_2 (g)$$

• Laser Risk (Thermal): Laser cutting generates Heat and Sparks (Ignition Source). When sparks meet Hydrogen, it leads to an immediate explosion.

• Waterjet Safety (Cold): Waterjet is a Cold Cutting method with no heat or sparks. The high-pressure water also acts as a "Scrubber" to wash away gas and heat. It is the standard safety method for chemical plants.

3.2. Comparison Table

Feature	Waterjet (Our Proposal)	Laser Cutting
Method	Cold Cutting (No Heat)	Thermal Cutting (High Heat)
Explosion Risk	Safe (No Ignition Source)	High Danger (Ignites Hydrogen)
Fumes/Gas	None (Washed by water)	Toxic Fumes (Needs Scrubber)
Maintenance	Good (Simple spare parts)	Difficult (Acid mist damages Lens)
Drain Speed	Fastest (Air Vent effect)	Slow/Medium (Turn-over required)
24h Operation	Possible (Double Intensifier) 6	Difficult (Lens cooling time)

4. Project Schedule

Aligned with the customer's new factory construction plan.

1. Decision & Contract: January 2026 (Final Technology Selection)

2. Manufacturing: Feb ~ April 2026 (Customized Design & Production)

3. Arrival at Site: End of April 2026

4. Commissioning: May 2026 (Joint test with Conveyor Line)

5. Mass Production: June 2026

5. Conclusion

The success of this recycling project depends on "Safety" and "Continuous Operation."

• Laser cutting is not suitable for 500-ton mass processing due to explosion risks.

• Our proposed [Double Intensifier Pump + Top & Bottom Waterjet] system guarantees the Safest, Fastest, and Non-stop production line.
