High Precision Jetting Valve for Miniature Speaker Assembly 500000 cps Support 3

Product Overview

This jetting valve system is designed for precise micro-dispensing in miniature speaker production and similar small-part assembly. It supports very thick fluids up to 500000 cps and includes a compact 3.55 kg controller for stable drive and easy mounting. Use this system when you need accurate placement of adhesive or damping material in tight spaces and high repeatability in production.

Problem

Many assembly lines cannot place very small adhesive spots reliably when materials are very thick or when cycle speed varies. This leads to uneven bonding, rework, and higher scrap rates in miniature speaker production.

Cause

Standard dispensers either struggle to push high-viscosity fluids through a fine nozzle or lose control of droplet size under frequent cycles. The fluid path, nozzle size, and drive control all affect droplet formation and repeatability, and poor matching causes inconsistent placement or clogging.

Solution

This jetting valve combines a compact controller and a smooth fluid path to keep droplet formation stable with viscous fluids. The system delivers repeatable volume per shot and reduces downtime through easier nozzle access and replaceable inserts.

Key benefits:

• Stable micro-dispensing with fluids up to 500000 cps
• Precise spot placement for small speakers and compact assemblies
• Reduced nozzle clogging and fewer line interruptions
• Compact controller weighs 3.55 kg for easier integration

Application

Miniature speaker assembly: precise adhesive dots for voice coil or damper bonding.
Small sensor and transducer production: controlled placement of potting or gap-filling materials.
Fine electronics: adhesive or sealant deposition where space is limited.
R&D and pilot lines: testing of high-viscosity materials with small sample volumes.

How It Works

Conclusion: consistent micro-droplets come from matched drive pulses and a stable fluid path. A short piezo or mechanical pulse in the valve chamber creates a pressure wave that ejects a droplet through the nozzle. The controller times pulses and adjusts amplitude to control droplet size and rate. For very viscous fluids, increase inlet pressure and, if allowed, raise fluid temperature slightly to aid flow while staying within material limits.

How To Choose 

Conclusion: pick the system that matches your droplet size, fluid viscosity, and cycle needs. Steps:

Confirm target droplet size and select the nearest nozzle diameter.
Provide your fluid viscosity at process temperature for a sample test if above 100000 cps.
Check required cycle rate and choose this model for moderate to high throughput.
Match wetted material to fluid chemistry (316L for general use, PTFE or ceramic where needed).
Ensure your pressure supply can keep steady pressure in the listed range.
Plan maintenance and spare nozzle inventory for continuous runs.

FAQ

Q1: Can this valve handle my 500000 cps fluid reliably?

A1: Many fluids at that viscosity can be dispensed with this system, but performance depends on fluid makeup and temperature. We recommend a sample test for final confirmation.

Q2: What is the smallest drop achievable in production?

A2: The system can produce drops down to about 1 nL. Production tuning for nozzle, pressure, and pulse settings is required for stable output.

Q3: How often should nozzles be replaced?

A3: Nozzle life depends on fluid abrasiveness and use. With non-abrasive fluids, nozzles often last many thousands of cycles. Abrasive materials reduce lifetime and require spare parts.

Q4: Is the 3.55 kg controller easy to integrate into existing lines?

A4: Yes, the controller is compact and designed for simple mounting. Provide your machine interface details for a seamless fit.

Q5: Do you provide tuning and on-site support?

A5: Yes. Our applications team can help tune parameters, run sample tests, and support integration either remotely or on-site.
