Bulk Two‑Tone USAPA Pickleballs – Top Exporter

These balls meet the official USAPA specifications for tournament play while being produced in high‑volume runs for distributors and club operators. The two‑tone color scheme is achieved through a co‑injection molding process that bonds contrasting polymer phases without adhesives. This construction provides consistent visibility on indoor and outdoor courts.

Technical Specifications

Diameter: 74 mm ±0.5 mm. Weight: 22.1 g ±0.3 g. Rebound height: 135 cm ±5 cm when dropped from 200 mm onto a granite surface. Hardness (Shore D): 68 ± 2. The seam tolerance is under 0.1 mm to prevent air leakage during extended play.

Material Composition

The core is formulated from impact‑modified polypropylene copolymer, selected for its low creep and consistent density across temperature ranges from -10 °C to 45 °C. The outer shell utilizes UV‑stabilized nylon‑6,6 with a pigment loading that yields the two‑tone appearance while maintaining a coefficient of friction suitable for paddle grip.

Manufacturing Process

Injection molding machines equipped with dual‑shot capability first deposit the core material, then immediately overlay the contrasting shell in a single cycle. The mold temperature is held at 190 °C for the core and 210 °C for the shell to ensure molecular interlocking. Post‑molding, balls undergo a controlled annealing step at 80 °C for 2 hours to relieve internal stresses.

Quality Control & Testing

Each batch is sampled at a rate of 1 per 500 units for weight and diameter verification using calibrated micrometers and analytical balances. Rebound testing is performed on a standardized drop tower with laser‑based height measurement. Visual inspection under 500 lux lighting checks for color uniformity, flash, and surface defects. Statistical process control charts monitor critical dimensions to keep Cp ≥ 1.33.

Applications

Club operators choose these balls for league play because the two‑tone design aids players in tracking spin and trajectory under varying lighting conditions. Tournament organizers value the tight tolerance distribution, which reduces variability in match outcomes. Training facilities benefit from the ball’s durability, retaining performance characteristics after over 5,000 impacts.

Typical Values

Packaging & Export Logistics

Bulk units are packed in double‑wall corrugated cartons containing 120 balls each, with inner polyethylene liners to guard against moisture. Cartons are strapped onto ISO‑standard pallets (1200 mm × 1000 mm) and stretch‑wrapped for stability. Each pallet carries a maximum of 48 cartons, corresponding to 5,760 balls, and is marked with handling symbols per ISPM‑15.

Customization Options

Clients may specify the proportion of the two colors (e.g., 70 % neon green / 30 % white) to match club branding. Logo printing is available via pad‑printing on the equatorial line, with a maximum of two colors and a resolution of 150 dpi. Custom mold inserts can be produced for alternative diameter tolerances upon request, subject to tooling lead time.
