Custom engineered transit case with precision foam insert From highly sensitive instrumentation and medical devices to weapons systems, audio/visual gear, and electronic components, our solutions are built to absorb shock, control vibration, and prevent movement during transport, storage, and field deployment. With virtually unlimited material, density, and configuration options available, each foam system is engineered specifically around your equipment—not forced to fit a generic layout.

Whether you require a single prototype, a pilot run, or thousands of production units, our team adapts quickly to evolving requirements, tight timelines, and complex technical specifications. Customers rely on Cases2Go not only for innovative foam solutions, but for our ability to respond to urgent, real-world deployment needs without sacrificing quality or accuracy.

Why Cushioning Design Matters

Custom foam inserts provide the most effective method of protecting equipment inside a transit case. A properly engineered cushioning system is designed to:

  • Absorb shock from drops and impacts
  • Reduce vibration during freight and vehicle transport
  • Prevent internal movement and component damage
  • Protect fragile components such as screens, connectors, lenses, and controls
  • Maintain consistent positioning for repeat deployments

Using detailed equipment specifications, weight distribution, fragility ratings, and transport conditions, our design team creates application-matched cushioning systems that meet both performance and durability requirements.

• Reduce vibration during freight and vehicle transport
• Prevent internal movement and component damage
• Protect fragile components such as screens, connectors, lenses, and controls
• Maintain consistent positioning for repeat deployments

Using detailed equipment specifications, weight distribution, fragility ratings, and transport conditions, our design team engineers custom foam inserts for cases that meet both performance and durability requirements.


CNC-Cut & Waterjet Foam Inserts

To achieve precision and repeatability, Cases2Go fabricates custom foam inserts using advanced CNC routing and waterjet cutting technologies.

These processes allow us to manufacture foam inserts with tight tolerances, clean edges, and highly repeatable layouts—ideal for OEM production runs, government programs, and enterprise equipment deployments.

CNC-cut foam inserts are particularly valuable when producing custom foam inserts for cases at scale, ensuring each insert matches the exact layout required for equipment protection.


We Build Custom Foam Inserts for Leading Case Manufacturers

Cases2Go designs custom foam inserts for cases from many of the most trusted manufacturers in the industry. If you already own rugged transit cases but need improved protection or updated layouts, our foam retrofit solutions provide engineered performance without replacing the case itself. We regularly design custom foam inserts for:

Custom Foam Inserts for SKB CasesCustom Foam Inserts for Anvil CasesCustom Foam Inserts for NANUK CasesCustom Foam Inserts for Platt CasesCustom Foam Inserts for ZERO ManufacturingCustom Foam Inserts for ZARGES Containers

Already have a case?
Simply provide your case model and equipment details, and our engineers will design a precision-fit custom foam insert for your case and equipment.

Types of Foam Cushioning Systems

Cases2Go provides solutions for even the most complex case and foam challenges.

Foam Filled Case with Layers

Foam Filled

Cases filled with layered foam using a single material or a combination of foams selected for performance and weight support.

Foam Lined

Foam Lined

Interior walls lined with foam—commonly 1” or 2”—to provide surface protection and impact absorption while maximizing usable space.

Diced (Pick-and-Pluck) Foam

Diced (Pick-and-Pluck) Foam

Typically polyurethane foam supplied in removable cubes. Best for short-term or low-precision applications.

Custom Foam Inserts

Custom-Engineered Cushion Systems

Precision-designed foam inserts fabricated using CNC or waterjet cutting for exact tolerances.

Custom Cushioning Enhancements & Interior Configuration Options

To further enhance organization, usability, and protection, we offer a wide range of interior configuration features:

Precision foam insert with contrasting foam for tool identification

Straps (Woven or Velcro)
Used to secure equipment in lid cushions or lift-out trays. Woven straps provide added strength for heavier components.

Lift-Out Trays
Maximize interior depth while allowing layered access to equipment and accessories below.

Hard Partitions
Distribute load, reinforce compartments, and provide structural separation between components.

Multi-Layer & Tool Control Foam Systems

Layered foam systems with contrasting colors provide immediate visual confirmation when tools or components are missing—supporting accountability and compliance requirements. These designs improve efficiency, reduce errors, and support standardized operating procedures.

These options allow us to design interiors that are not only protective, but intuitive and efficient for real-world use.

Foam Material Options & Performance Characteristics

Not all foam performs the same. Our engineers select materials and densities based on equipment weight, fragility, environment, and usage—not convenience. Our foam selection includes a broad inventory of closed-cell and open-cell materials with densities engineered to support light, fragile components through heavy industrial equipment.

Polyethylene (PE)
Firm, closed-cell foam ideal for heavier equipment. Offers excellent vibration dampening, durability, and moisture resistance.

Crosslinked Polyethylene
High-density closed-cell foam with superior surface protection and water resistance. Commonly used for medical devices and Class “A” surface finishes.

Polyurethane (PU)Softer, open-cell foam best suited for lightweight, highly fragile equipment with low drop-height tolerances. Available in polyether and polyester formulations.

Anti-Static Foam
Available in both PE and PU formats. Designed to inhibit static buildup and safely dissipate charge for sensitive electronics.

Static Dissipative Foam
Mid-range electrical resistance foam offering controlled charge dissipation.

Conductive Foam
Provides the highest level of electrical conductivity and EMI shielding, instantly draining static charges.

Polystyrene (EPS / Styrofoam)
Ultra-dense molded foam used for specific packaging applications requiring rigid form and compression strength.

Common MIL-SPEC Foam Materials

We routinely work with military and government specifications, including:

  • PPP-C-1752 Type I, Class 2
    Gray · 2 PCF (standard) or 4 PCF (high density)
  • MIL-P-26514 Type I, Class 2
    Gray · 2 PCF (standard) or 4 PCF (high density)

Our team is experienced in documentation, repeatability, and compliance requirements for defense and government programs.
