Finding a Plastic Parts Heater for Safe & Quick Warm-up

Click For Summary

Discussion Overview

The discussion revolves around finding an effective method to heat plastic parts to a stable temperature of 120 degrees F for easier assembly with metal pins. The focus is on practical solutions that ensure safety and efficiency in the assembly process.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant describes the need for a quick and safe method to heat plastic discs for assembly, noting that current methods result in the parts losing heat too quickly.
  • Another participant suggests using a heat gun as a potential solution for heating the parts more effectively.
  • There is a concern raised about the practicality of using a heat gun, as it may slow down the assembly line due to the need for manual operation.
  • A participant proposes using the freezer to temporarily shrink the metal pins, which could facilitate easier assembly.

Areas of Agreement / Disagreement

Participants express differing views on the practicality of using a heat gun, with some seeing it as a viable option while others are concerned about its impact on assembly efficiency. The freezer idea is met with interest, indicating a potential area of agreement.

Contextual Notes

Participants have not reached a consensus on the best heating method, and there are unresolved concerns regarding the efficiency and safety of the proposed solutions.

Hello,

I am looking for something to keep plastic parts warm and pliable. We have plastic discs that need metal pins snapped into some grooves and they snap wayyy to tight. We checked with a vendor and the material is still within spec, but I cannot change the material

It takes one minute to snap all the fittings in place. So we need the parts up to a stable 120 degrees F relatively quick, but on the other hand the parts can get too hot to handle if left under the lamp for too long and we are then looking at a fire hazard and many burnt fingers.

I have tried this already:

We tried a setup that heats the parts up to 120 degrees F one at a time. They each would sit under the lamp for a minute. The part lost its heat by the time you took it out and assembled it, and if we made it any hotter we wouldn't be physically able to touch the plastic discs.

I need a quick cheap way to heat these plastic parts. I was looking at picking a lower wattage bulb or maybe a long bar lighting component so we can expose more parts to the heat for a longer period of time at a safer level. Even if I could have 2 stations: One "on deck" and one "up to bat" I can lower the wattage of bulb, double the exposure time, and make the process a lot safer.

Just looking for ideas. I thank you in advance for any input/advice!

I haven't seen anything like that yet. The only problem with that is it would slow down our assembly line with people holding the gun and snap fitting the pins. There just wouldn't be enough hands
 
I just might try that freezer idea though!
