Case Foam Inserts - Protection for Your Products

Your valuable products deserve more than just a case. They deserve engineered protection that travels with them.

At Polyformes, our bespoke case foam inserts are custom-cut to your equipment, offering optimal shock absorption, component retention and presentation quality.

Whether for field engineers, sales demo kits, electronics, medical devices or delicate instruments, a well-designed foam insert can be the difference between safe arrival and costly damage.

You can even take it one step further and turn it into a sales tool by branding the inserts with 4 colour print or laser etching.

Case Foam Inserts

Why Choose Custom Case Foam Inserts?

1. Minimise Movement & Prevent Damage

Poorly supported items shift under transport forces. A snug-fit insert guarantees each component sits exactly in place, eliminating vibration, collision and abrasion.

Case foam inserts provide high protection, are custom-fit to minimise movement and prevent transit damage.

2. Engineered Shock & Impact Absorption

Not all foam is the same. By selecting the correct density, thickness and grade, a foam insert can cushion against drops and vibration. This is how you prevent breakage and maintain calibration. Using CAD / design software to calculate the optimum foam density and grade for your items.

3. Protection of Sensitive Surfaces

High-value items often have polished, coated or delicate surfaces. Foam inserts offer a soft, conforming barrier that resists scratching, marring or staining under repetitive contact. A no-brainer when it comes to enhancing your protective cases.

4. Aesthetic & Branding Enhancements

Beyond protection, foam inserts can be a sales tool. Options include:

  • Laser etching or branding (logos, part numbers, instructions)
  • Two-tone / shadow board inserts (contrasting foam layers to highlight absent parts)
  • Colour-matched foam to align with your corporate identity

Layering foam colours or laminating for better presentation and tool control effects.

5. Faster Packing, Fewer Returns, Better Reputation

A clean, pre-cut insert speeds up packing, makes missing items obvious at a glance, and dramatically reduces returns from damaged goods. It's both an operational and brand win.

Core Materials & Technologies We Use

We work with a range of advanced foams, each selected for its protective, handling or aesthetic properties.

Foam Type Ideal Use Cases Key Strengths
Plastazote® (cross-linked PE foam) Sensitive equipment, electronics, aerospace Excellent shock absorption, chemical inertness, moisture resistance, wide colour range
Standard PE / Ethafoam General or high-volume inserts Cost-effective, reliable protection in many transit uses
ARPLANK / Recycled Foams Sustainable packaging lines Reduced environmental impact, designed for recycling

We combine CNC routing, laser cutting, lamination and foam layering to deliver the final insert exactly to your specifications.

Case foam inserts will be designed and manufactured to follow every contour of your items. Specialist software can calculate the required density for the optimum level of protection.

How We Work Together - From Concept to Delivered Insert

  • Share your item data — Upload CAD, drawings or dimensions.
  • Design & engineering — We propose foam materials, layout, thickness and cut style.
  • Prototype / sample stage — Approve a small run or mock insert.
  • Production & finishing — Laser etching, colour layering, edge treatment.
  • Fit test & delivery — Insert into cases (or ship cases & foam together).

Throughout, we guide you in choosing optimal foam grade, density, and protective layering based on your application.

Typical Applications & Use Cases

  • Field service kits & demonstration cases
  • Test & measurement / scientific instruments
  • Medical, surgical / diagnostic device transport
  • Electronics, cameras, drones, surveying gear
  • Drone / UAV payloads / sensor kits
  • Aerospace / defence modules

No matter your industry, well-engineered foam adds peace of mind, reduces logistic losses and improves the perceived value of your kit.

Case Foam Inserts Frequently Asked Questions

What is the difference between pick-and-pluck foam and customised inserts?

Pick-and-pluck foam is pre-scored and allows generic cubing; it's flexible but less precise. Custom inserts are designed to your product contours, offering superior retention and protection.

Can you handle waterproof or rugged external cases (Peli®, Storm, etc.)?

Absolutely. We design inserts to work with waterproof, aluminium, plastic, and flight cases. We can even source the case for you to ensure compatibility.

What colours are available?

We stock a wide palette of colours in most foam grades. You can layer colours or choose contrast inserts for tool control or branding.

Do you offer anti-static or conductive foams?

Yes - for electronics or sensitive equipment, we supply specialist static-dissipative or conductive foam grades.

How long does it take?

From design approval to delivery typically takes 7 to 21 working days, depending on quantity and complexity.
