Henkel’s renowned TECHNOMELT® low pressure molding solutions are the benchmark for modern PCB and circuitry protection. The simplicity of these products is their advantage: because the entire TECHNOMELT® operation takes place at low pressure, cycle time is short and fine or fragile circuitry is not damaged. See how beneficial TECHNOMELT® can be as an alternative for your potting and encapsulating processes.

Henkel’s low pressure molding materials deliver exceptional electrical insulation and excellent temperature, vibration and solvent resistance for many applications. The TECHNOMELT® product range protects electronics from the harshest environmental conditions, including high humidity, long-term UV exposure and extreme thermal cycling.

Low Pressure Molding Technology

Low pressure molding is a faster and more efficient process than conventional potting. TECHNOMELT® is a one-part material that requires no mixing or curing; reduces material consumption through streamlined, multi-level, contour-exact encapsulation; and offers a sustainable solution through its unique re-usable formulation and green chemistry. Integrating TECHNOMELT® as an alternative to potting also reduces part numbers by eliminating the need for a housing or additional parts to achieve strain relief.

The Benefits
Henkel's TECHNOMELT® product range has many beneficial aspects for your manufacturing:

  • Fewer process steps
  • Reduced equipment and operations footprint
  • Faster cycle time per part
  • Fewer machines and manufacturing lines
  • Low-viscosity materials allow for low injection pressures

The Process

How does low pressure molding with TECHNOMELT® work? It's really simple, because you are able to encapsulate your electronic products in only three steps:

  1. Insert bare electronics into your predesigned mold set
  2. TECHNOMELT® encapsulates electronics at low pressure and temperatures
  3. Test parts and move them to final assembly — immediately after molding

Your Cost Savings

What does low pressure molding mean for production costs? The answer: Big savings.

Fewer physical parts, lower equipment costs, reduced shipping expenses and inventory levels, and many more cost-lowering advantages translate to bottom line benefits. Use our cost calculator and see the savings for yourself.
