Manufacturing Help -- Need a highly viscous material

Click For Summary

Discussion Overview

The discussion centers on finding a highly viscous material suitable for a manufacturing process involving RF connectors and adapters. Participants explore various options for a non-toxic gel or liquid that can cushion parts as they exit automated machinery, preventing damage during accumulation. The context includes considerations of cost, viscosity, and ease of cleaning.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • The original poster seeks a low-cost, non-toxic viscous solution, noting that a cornstarch and water mixture was ineffective due to odor and cleanup issues.
  • One participant suggests gear oil, mentioning its higher viscosity compared to motor oil and referencing thick oil additives that may have a honey-like consistency.
  • Another participant proposes using clean water covered with soft beads or balls to cushion the parts as they land.
  • A different suggestion involves using a moving conveyor belt to manage the exit of parts without direct impact.
  • Glycerin is mentioned as a potential option for viscosity.
  • Lanolin is proposed, with the idea of adjusting viscosity using hydrocarbon solutions.
  • Metamucil combined with mineral oil is suggested as a biodegradable option, along with pectin as a potential thickening agent.

Areas of Agreement / Disagreement

Participants present multiple competing views and suggestions without reaching a consensus on the best solution. Various materials and methods are proposed, but no single option is agreed upon as superior.

Contextual Notes

Participants express uncertainty regarding the exact viscosity requirements and the effectiveness of suggested materials. There are also considerations about the final packaging process and how it may integrate with the manufacturing setup.

Who May Find This Useful

Manufacturers looking for solutions to protect delicate components during automated processes, as well as those interested in exploring non-toxic and cost-effective materials for industrial applications.

First time post, I appreciate any advice!

I own a small manufacturing company that makes RF connectors and adapters. Our automated machinery makes the connector bodies out of brass, and many of the parts we make have fairly delicate threads or features that are easily damaged when one part exits the machine and lands on another part via the machine's exit "chute".

We often run our machines "lights out", so I'm hoping to find an inexpensive, and non-toxic highly viscous gel or liquid that we can use to drop parts into as they exit a machine. Ideally, we would place this viscous liquid in a 5 gallon bucket to allow for part accumulation yet preventing parts from dropping directly onto each other or hitting each other with force.

We've tried a cornstarch and water mixture and that provided the viscosity we want, but the mixture began to smell badly after a day or two and frankly was a mess to clean off of the parts when they dropped into the 5 gallon bucket. I've seen 5 gallon buckets of silicone liquid that appears to be viable solution, but those are sold for $200 or more, and I would need hundreds of gallons per year.

Does anyone have any suggestions of a relatively low cost industrial solution, or a home made option? For reference, the viscosity of honey may be too high, probably looking for something slightly less viscous than honey, but more viscous than motor oil. End use is at room temperature.

Gear oil? It is more viscous than motor oil. Not sure how it measures against honey, but I recall the thick oil additives (STP, 'Miracle Oil') were honey-like.

This chart shows gear oils from 70W to 250W, compared to typical 30W motor oil.

I can't visualize your set up, but how about an air flow to slow them down? No clean up.
 
Maybe you could use clean water in the 5 gallon bucket, but cover the surface with a layer of soft free floating beads or balls. The components will hit the layer of soft balls first, roll through the layer, then sink at a controlled rate to the collect at the bottom.

Welcome to the PF. :smile:

What is the final packaging like? Maybe just invest in combining this fabrication process with the final packaging step.
 
glycerin?
 
Lanolin

Viscosity adjusted by solution with hydrocarbons
 
metamusal-- and mineral oil - any source of vegin -pectin- biodegreatable!
