Core Mechanical Design

// Frolick baby teether

Give them something to drooool over.

We developed a prototype concept into a fully certified, volume-production consumer product. The core challenge was engineering a complex dual-material overmoulded design that needed to be structurally rigid in some areas whilst remaining soft and safe for chewing in others – all while meeting stringent FDA material approvals and passing rigorous choke hazard testing.

The product is now in full volume production and sold worldwide.

The Core Challenge & Solution

The Problem

Bringing a Safety-Critical Baby Product to Market

img

Dual-Material Design: The product needed to combine a rigid structural core with soft chewable zones - requiring an overmoulding process that had to work consistently in volume production.

img

Manufacturing Complexity: Achieving reliable bonding between two dissimilar materials in an overmoulding process at scale, without defects or delamination.

img

Regulatory Compliance: All materials had to be FDA approved and free from harmful substances, with full documentation for market access.

img

Safety Testing: The geometry had to be engineered to pass rigorous choke hazard standards, requiring careful optimisation of dimensions and form.

The Solution

Precision Overmoulding, Certified for Production

img

Engineered an innovative overmoulding approach that achieved reliable dual-material construction at volume, with rigid core and soft chewable zones performing exactly as required.

img

Selected FDA-approved material combinations that met all regulatory requirements whilst delivering the tactile and durability properties needed for a baby product.

img

Optimised the geometry through iterative design to pass choke hazard and safety testing, giving the client a clear route to market.

img

Supported the full transition from prototype to volume production. The product is now sold globally by Frolik+Co (frolikandco.com).
