SUMMARY

This discussion focuses on creating a hard metal toolkit handle using high-density polyethylene (HDPE) tubing. Key methods include drilling a pilot hole in a solid black HDPE rod and heating the metal tool to press it into the hole, allowing the HDPE to conform and bond. Alternative techniques suggested involve using a two-part resin, splitting the tube lengthwise for packing, or melting HDPE chips in a closed container to form a handle. Each method emphasizes the importance of proper material handling and temperature control for effective adhesion.

PREREQUISITES
  • Understanding of high-density polyethylene (HDPE) properties
  • Basic knowledge of metalworking techniques
  • Familiarity with adhesive materials and their applications
  • Experience with heat application methods for metal and plastic
NEXT STEPS
  • Research techniques for heating metal tools safely and effectively
  • Learn about different types of adhesives suitable for HDPE
  • Explore methods for melting and molding HDPE
  • Investigate the properties and applications of two-part resins like polyurethane
USEFUL FOR

This discussion is beneficial for DIY enthusiasts, metalworkers, and anyone interested in custom tool fabrication using HDPE materials.

TL;DR
Making toolkit handle from high density Polyethylene
How do we make hard metal toolkit handle from high density Polyethylene tube/pipe inside which the tool near end is united, glued by some material (black as seen for now, try to give pic. later on)
 
Engineering news on Phys.org
Get solid black HDPE rod. Drill a pilot hole in the end of the rod for the handle end of the hard metal tool.
Heat the handle end of the hard steel tool sufficiently to press it into the pilot hole in the HDPE.
The hot metal will melt the HDPE which will conform to the tool, stick and then shrink on.
 
Thanks... but sorry I've to suspend it moment as only way here & now is the hollow HDPE

Sorry, could you please try that translation again? So far I'm not able to parse what you just said. Thanks.
 
Sorry, still not clear. Can you maybe reply in your native language, and I'll try to translate and interpret it? Thanks.
 
as said the way here & now is the hollow HDPE

What is ID & OD of HDPE pipe, what is length of handle?

Here are three more ways.
1. Use a two part resin as a filler. Maybe polyurethane or whatever is used nearby.
2. Split some tube length-ways in a bandsaw to make packing to fit in the handle. At the same time cut some long thin tapered wedges. Hammer the wedges into the tube as packing around the metal. Secure the wedges by melting the ends together at the ends of the pipe.
3. Cut up HDPE tube into chips, then melt it in a closed metal container, (to keep out air).
Pour the melt into an HDPE tube handle or a mold, then wait for it to cool.
