Golf Ball

• Core Design:
  
  • Solid Core: Typically made of synthetic rubber (e.g., polybutadiene) blended with additives like zinc oxide for energy transfer.
• Layer Construction:
  
  • Two-Piece: Core + durable ionomer cover (e.g., Surlyn®) for distance and durability.
  • Multi-Layer (3–5+ pieces): Adds mantle layers (ionomer, thermoplastic) to optimize spin and control.
• Cover Material:
  
  • Urethane: Premium balls for soft feel and high spin.
  • Surlyn®: Durable, cut-resistant for recreational use.

2. Core Production

1. Mixing: Rubber compounds are blended with curing agents and accelerators.
2. Compression Molding:
   
   • The mixture is heated and pressed into spherical cores under high pressure.
   • Cores are cooled and polished to ensure smoothness.

3. Layer Application

• Mantle Layers (for multi-layer balls):
  
  • Thermoplastic or ionomer materials are injection-molded around the core.
  • Enhances energy transfer and reduces spin for longer drives.
• Intermediate Layers: Optional additional layers for spin control or feel.

4. Cover Molding

1. Injection Molding:
   
   • Urethane or Surlyn® is injected into dimpled molds around the layered core.
   • The mold’s cavity defines the ball’s dimple pattern (300–500 dimples).
2. Cooling: Rapid cooling solidifies the cover while retaining dimple geometry.

5. Dimple Design & Aerodynamics

• Dimple Patterns: Proprietary designs (e.g., hexagonal, tetrahedral) optimize lift and reduce drag.
• Testing: Wind tunnel and robotic swing tests validate flight stability and distance.

6. Painting & Branding

• Base Coat: White or colored paint is applied via automated spray systems.
• Printing: Logos, numbers, and alignment aids are pad-printed or stamped.
• Clear Coat: A UV-resistant layer protects the finish.

7. Quality Control

• Weight & Size: Must meet USGA/R&A standards (≤ 1.620 oz, 1.68” diameter).
• Roundness: Checked via laser scanners; deviations > 0.01” are rejected.
• Compression: Tested to ensure consistency (e.g., 70–100 compression ratings).
• Performance: Robot-tested for launch angle, spin rate, and carry distance.

8. Packaging

• Balls are sorted into sleeves (3) or boxes (12) with branding and performance details.
• Recyclable or eco-friendly packaging is increasingly used.
