FAQ
Q: How do I calculate the right mold size for my gummy? A: Determine your target weight, then use the volume formula: Volume = Weight ÷ Density. Our engineering team can help with calculations.
Q: What's the most popular gummy mold size? A: Standard bear shapes (25×20×12mm, 2-2.5g) are the most popular for CBD and vitamin gummies.
Q: Can I change the cavity size on an existing mold? A: No, cavity size is fixed once the mold is manufactured. Custom molds are made to your specifications.
Q: How many gummies can I produce per day with one mold? A: A 200-cavity mold producing 2g gummies can make approximately 2,400 pieces per day (6 cycles × 200 cavities).
Conclusion
Selecting the right mold size ensures consistent product weight, proper dosing, and efficient production. Use this size chart as a starting reference, and consult our engineering team for custom sizing based on your specific requirements.
