Concentric Auger Valve with 170 cc Reservoir for Precision Electronics Dispensing

Product Overview

This concentric auger valve meters adhesives and pastes by positive displacement using a concentric screw design. Available reservoir sizes include 30cc, 50cc and 170cc to match production needs. The 170cc option reduces refill cycles on high-volume lines. The valve is built for repeatable deposits, simple nozzle change, and straightforward cleaning for electronics assembly and module bonding.

Problem

Assembly lines slow when frequent refills or inconsistent deposits interrupt production and increase rework.

Cause

Small reservoirs force frequent intervention and pressure-feed setups can introduce pulses or air, creating variable bead shape and shot volume. For viscous materials, poor feed design worsens these problems.

Solution

This concentric auger valve provides positive displacement metering with a choice of reservoir capacities up to 170cc. The larger reservoir reduces manual refills while the screw drive ensures steady, low-pulse output. Quick-release heads and standard nozzle fittings make maintenance and changeover fast, keeping lines running.

Technical parameters

Application

• PCB and module bonding: repeatable adhesive dots and beads for connectors and components.
• Thermal interface and vapor chamber assembly: controlled paste placement for TIM seating.
• Multi‑point dispensing: one valve feeding several small outlets or multiple robot heads.
• Pilot and production lines that benefit from fewer refills and easier maintenance.

How It Works

The concentric screw rotates to displace material forward; screw rpm sets the delivered volume. The reservoir feeds the screw without introducing air; larger reservoir sizes reduce refill frequency and stabilize feed pressure. Material passes through a short fluid path to the nozzle, reducing dead volume and improving shot-to-shot consistency.

How To Choose

1. Pick reservoir size to match run length and refill tolerance (choose 170cc for longer uninterrupted runs).
2. Provide fluid viscosity at working temperature so we can confirm screw clearances and nozzle recommendations.
3. Select nozzle diameter to meet your target dot or bead size.
4. Choose feed method: large reservoir with gravity feed or pressure pot for extended runs; use a stable regulator for pressure feed.
5. Consider encoder feedback or flow sensors for closed-loop verification in tight‑tolerance lines.
6. Request a bench test for abrasive or very high-viscosity materials.

FAQ

Q1: Why choose the 170cc reservoir option?
A1: It reduces refill cycles on high-volume lines, lowers operator intervention, and helps maintain stable feed for extended runs.

Q2: Can the valve handle abrasive or filled pastes?
A2: Yes. Specify ceramic or coated wetted parts and plan for spare parts; we recommend a bench wear test for abrasive formulations.

Q3: What flow can I expect for my paste?
A3: Flow depends on viscosity and nozzle; typical working range is 0.5–80mL/min. Send your fluid data for a tailored estimate.

Q4: How is repeatability measured?
A4: Repeatability is measured as consistent shot volume after tuning with steady feed and correct nozzle—typical values ≥95% in production-like tests.

Q5: Do you offer sample testing and integration support?
A5: Yes. Send fluid samples and operating conditions; we run bench tests, return logs and recommend settings for production integration.
