OEM Kids Cartoon Bicycle Safety Helmet Factory

The factory specializes in producing bicycle safety helmets sized for children aged 3 to 12 years, incorporating licensed cartoon graphics while meeting impact‑performance criteria.

Materials and Construction

Outer shells are made from injection‑molded ABS with a nominal thickness of 2.0 mm, providing a balance between rigidity and low weight.

Impact‑absorbing liners use expanded polystyrene (EPS) foam with a density range of 20–25 kg/m³, tuned to limit peak deceleration to under 250 g in standardized drop tests.

Retention systems consist of nylon webbing straps adjusted via a side‑release buckle, delivering a tensile strength of at least 22 N before slip.

Safety Standards and Testing

Helmets are evaluated against EN 1078 and CPSC 1203 protocols, which specify impact attenuation, penetration resistance, and field of view requirements.

Each production lot undergoes a sample drop test on a flat anvil at speeds corresponding to 2 m/s, with acceleration measured by a tri‑axial logger; results are recorded and compared to the limit of 250 g peak.

Ventilation is quantified by the total open area of vents, typically 12 % of the helmet surface, ensuring adequate airflow without compromising structural integrity.

Design and Customization Options

Cartoon graphics are applied using water‑based inks that comply with REACH restrictions, allowing for full‑color prints on the helmet’s outer shell.

• Available sizes: Small (48‑52 cm head circumference), Medium (52‑56 cm), Large (56‑60 cm).
• Ventilation configurations: 6‑8 frontal vents, optional rear exhaust ports.
• Retention colors: black, navy, or custom‑matched to brand palette.

Tooling for new cartoon designs can be supplied as CAD files; lead time for artwork approval is typically 5‑7 business days.

Manufacturing Process and Quality Control

Shells are produced on a 150‑ton injection molding machine with cycle times of 45 seconds per part, ensuring dimensional repeatability within ±0.1 mm.

EPS liners are cut using CNC hot‑wire machines to tolerances of ±0.5 mm, then bonded to the shell with a water‑based adhesive that meets VOC limits of <50 g/L.

In‑process checks include weight verification (target 210 g ± 15 g), strap tension measurement, and visual inspection for print registration.

Final audit uses a statistical sampling plan (AQL 1.0) for critical dimensions and impact performance.

Applications and Use Cases

These helmets are suited for municipal bike‑share programs targeting youth fleets, where standardized sizing and recognizable graphics improve compliance and reduce loss rates.

School‑based cycling safety courses benefit from helmets that combine certified protection with engaging designs, encouraging consistent wear among participants.

Retail distributors can offer private‑label versions with customized cartoon themes, allowing differentiation in competitive markets while maintaining the same safety baseline.

Frequently Asked Questions

• Can the helmet dimensions be customized? Yes, head‑circumference ranges can be adjusted by modifying the EPS liner geometry; tooling changes are quoted per project.
• What information is required before quotation? Required details include target size range, preferred cartoon artwork (vector files), order quantity, and any special packaging requests.
• Which materials are available for the shell? Standard ABS is offered; alternative polycarbonate blends are available upon request for higher impact resistance.
• How is quality inspected? Each lot undergoes dimensional checks, strap tension testing, and a sample impact test per EN 1078; results are documented in a test report.
• What packaging methods are available? Helmets can be packed in individual polybags, placed in master cartons with corrugated dividers, or supplied in reusable crates for regional distribution.
• How are export shipments protected? Cartons are strapped and corner‑protected; moisture‑barrier liners are added for sea freight to prevent condensation.
• What is the typical production lead time? For standard artwork, lead time is 18‑22 working days after sample approval; custom graphics add 5‑7 days for artwork preparation.
• How are samples arranged? Pre‑production samples are shipped via express courier; charges are credited against the first purchase order.
