Two‑Component Screw Platen Pump for EV Bonding 80–800 mL/min Flow Rate

Product Overview 

This two‑component screw platen pump delivers steady metering and mixing for EV bonding where high throughput and accurate mix ratio are required. The unit meters A and B components, maintains the set ratio, and supplies a mixed output ready for dispensing or downstream application. Choose this pump when you need continuous production of adhesive or sealant at repeatable volume and correct ratio from 80 up to 800 mL per minute.

Problem 

EV bonding lines fail when adhesive mix ratio drifts or output volume is unstable, causing weak bonds, rejects, or rework.

Cause 

Inaccurate metering, air ingress, or varying supply pressure cause ratio error and flow fluctuation. Manual feeding or poorly matched pumps increase waste and downtime on high‑volume lines.

Solution 

Conclusion: this screw platen pump combines positive metering, synchronized screw drive, and a fixed mixing head to deliver a constant flow and correct mix ratio. It reduces material waste, shortens setup time, and keeps bond quality stable across long runs.

Technical Specifications

Application 

• EV battery module bonding: structural adhesives for cell packs and busbar potting.
• Motor and power electronics: large area sealants and gap filling.
• Chassis assembly: structural adhesives applied at high throughput.
• Automated dispensing cells: feed to multiple dispense heads or to in‑line mixing and dispensing systems.

How It Works 

Conclusion: synchronized screw displacement meters each component and forces them through a mixing head at the set ratio.

Twin screws rotate at matched speeds; the platen holds cartridges or feed ports and ensures positive displacement. The components are pushed into the mixer where they combine and exit as a homogeneous stream ready for dispensing. Drive speed sets flow; gear ratio sets mix ratio when using direct drive metering.

How To Choose 

Conclusion: select pump options based on throughput, ratio, material and cleaning needs.

Steps:

1. Define required flow (mL/min) per line or per head and pick model for peak throughput.
2. Provide target mix ratio and material viscosities at working temperature so we can size screws and select the correct mixer.
3. Decide feed method (cartridge, pressure pot, bulk) and whether reservoir heating is needed to lower viscosity.
4. Choose wetted materials based on fluid chemistry (316L for general adhesive; specify if aggressive).
5. Consider optional items: flow sensors for in‑line verification, purge kit for fast cleaning, and spare static mixers.
6. Schedule a short pilot run or bench test with your material to confirm settings before production.

Maintenance and Cleaning

Conclusion: designed for regular production use with straightforward maintenance.

Quick‑release mixing head and replaceable mixer elements speed changeover.
Flush and purge sequences are supported; purge module optional for automated or remote systems.
Keep spare screws and mixer inserts on site for fast swaps on heavily filled or abrasive materials.

FAQ 

Q1: Can this pump run continuous 800 mL/min for whole shifts?
A1: Yes — when configured with appropriate drive, cooling/heating and reservoir supply. We recommend a pilot test to confirm with your material and duty cycle.

Q2: How precise is the mix ratio?
A2: Typical metering accuracy is ±1~3% by volume when the system is set up per recommended feed and with stable material properties. Flow sensors improve verification.

Q3: Can it handle filled or abrasive adhesives used in EV bonding?
A3: Yes. Screws and wetted parts can be specified with harder coatings and larger clearances for abrasive or filled pastes. Provide sample data for final recommendations.

Q4: What cleaning is required between batches or color changes?
A4: The mixer and head are removable for manual cleaning; an optional purge module lets you flush lines automatically. We can advise a cleaning plan based on material.

Q5: Do you offer test runs with our adhesive?
A5: Yes. Send your material sample and process notes; we can run bench or pilot tests and return logs and recommended settings.
