🚀 The Future of Electronics Protection: Why Low-Pressure Overmolding Wins

Out with the Old: Potting and Conformal Coating

For decades, electronics protection has been stuck in the past. Traditional methods like potting and conformal coating—while functional—come with real baggage:

  • Long cure times
  • Messy, manual processes
  • Bulky enclosures
  • High material and labor costs

These are legacy solutions. And legacy slows you down.


In with the New: Low-Pressure Overmolding (LPO)

At Amtech, we believe protection shouldn’t be a bottleneck—it should be a launchpad. So we reimagined the process using first principles and engineered something smarter: Low-Pressure Overmolding.

LPO uses low-viscosity materials injected at low pressure to encapsulate electronics without damaging sensitive components. It’s precise. Fast. Scalable.


Why It’s a Game-Changer

Forget curing. Forget compromise. Here’s what LPO delivers:

  • ⚡ Zero Cure Time – Rapid cycle times accelerate production
  • đź’Ş Shock & Vibration Resistance – Designed for rugged environments
  • đź’§ Moisture Barrier – Protects against water and contaminants
  • 🔥 Superior Thermal Conductivity – Keeps components cooler, longer
  • đź§° Simplified BOM – Eliminates lids, fasteners, and other extras
  • đź§ľ Lower Tooling Costs – Ideal for prototyping and short runs
  • 📦 Smaller Package Sizes – Enables more compact, efficient designs

The Cost Advantage

Let’s talk numbers:

Method – Cost/Unit
Potting – $4.89
Conformal Coating – $1.87
Low-Pressure Overmolding – $1.65

That’s not just savings—it’s scalability. For high-mix, low-to-mid volume production, this unlocks next-level efficiency.


Built for Harsh Realities

LPO isn’t theory—it’s already out in the wild, delivering results for:

  • đźš— Automotive (OEM & Aftermarket)
  • 🏥 Medical Devices
  • ⚙️ Industrial Automation
  • 🦺 Safety Equipment

Whether your product lives on the road, in the field, or in a critical care unit, LPO stands up to the challenge.


Proven by Amtech

At Amtech, we’ve helped companies launch overmolded products faster, cheaper, and more reliably. We’ve even built custom automation platforms to scale production with soldering and hot melt dispensing built in.

This isn’t just innovation—it’s execution.
