01 / ENCLOSURES
Cosmetic Body Panels & Enclosures
The outer shell of a humanoid robot is more than aesthetics — it protects internal systems, defines interaction safety, and carries the brand identity of the platform. RobTronic manufactures enclosures for chest, shoulder, forearm, shin and head assemblies across all major humanoid platforms, with Class-A surface finishes and tight dimensional tolerances.
INJECTION MOULDING
Injection-Moulded Body Panels
ABS, PC and PC-ABS panels for chest, shoulder and limb covers. Multi-cavity tooling for consistent Class-A finish. Surface texture and paint-ready primer included.
CNC PRECISION
CNC-Machined Cosmetic Parts
Aluminium or polycarbonate accent panels machined to ±0.05 mm. Anodised, brushed or powder-coated. Ideal for joints, wrist caps and structural-cosmetic hybrids.
RAPID PROTOTYPING
3D-Printed Rapid Enclosures
SLA and MJF printed shells for EVT and DVT builds. Functional surface finish, 7–14 day lead time from CAD. Bridge tooling before injection moulding.
BIONIC FACE ASSEMBLY
Facial & Head Assemblies
Multi-layer face panel assemblies combining rigid inner frame, silicone mid-layer and cosmetic outer skin. Compatible with actuated eye and mouth mechanisms.

02 / SIGNATURE SERVICE
Custom Silicone Robot Skin
Platinum-cure silicone skin is the defining feature of HRI-grade humanoid robots. RobTronic designs, moulds and finishes silicone skin panels that match specified shore hardness, anatomical geometry and surface texture — biocompatible, heat-stable and ready for integration over servo-driven face and hand mechanisms.
SKIN TEXTURE
Realistic Texture & Tone
Custom shore hardness (10A–40A), skin-like texture moulding and pigment-matched coloration for face, hands and forearm panels. Designed to pass HRI tactile safety standards.
ANATOMICAL GEOMETRY
Anatomical Moulding
Face, hands, forearm and torso panels moulded from 3D scans or engineering drawings. Undercut geometries, multi-part split moulds and overmoulding onto rigid substrate all supported.
PLATINUM-CURE SILICONE
HRI-Safe Materials
Platinum-cure silicone — biocompatible, phthalate-free, skin-safe and UL-listed options available. Operating range −60 °C to +200 °C. Zero shrinkage post-cure.

03 / INTERACTION SURFACES
Soft-Touch HRI Components
Where a robot meets a human, material choice becomes a safety specification. RobTronic engineers soft-touch overmoulded grips, padded joint covers, compliant fingertip pads and tactile surface panels that absorb impact, reduce perceived rigidity and satisfy ISO/TS 15066 collaborative contact force limits.
OVERMOULDING
TPU & TPE Overmoulded Grips
Shore 30A–60A thermoplastic elastomer overmoulded onto rigid ABS or aluminium substrates. Applied to wrist handles and forearm grip zones.
IMPACT ABSORPTION
Compliant Joint & Link Covers
Foam-core or gel-filled polycarbonate shells fitted over elbow and shoulder joints. Designed to reduce peak contact force below 50 N.
TACTILE SENSING READY
Fingertip & Palm Pads
Platinum-cure silicone fingertip pads with embedded pressure sensor channels. Compatible with capacitive and resistive tactile arrays.
| PROPERTY | SPECIFICATION |
|---|---|
| Overmould Hardness | Shore 30A – 60A (TPU/TPE) |
| Silicone Pad Hardness | Shore 15A – 25A |
| Peak Contact Force (ISO/TS 15066) | ≤ 50 N |
| Substrate Bond Strength | > 2 MPa |
| Operating Temperature | −20 °C to +80 °C |
| Certifications | RoHS · REACH · SVHC-free |
| Lead Time (prototype) | 7 – 14 days |
