Custom Gummy Mold Design: From Sketch to Production

Introduction

Custom gummy mold design is the process of creating a mold tailored to your specific product requirements. Unlike stock molds that offer standard configurations, custom molds are engineered from the ground up to match your exact dimensions, production volume, and branding needs.

This guide explains the custom gummy mold design process and what to expect at each stage.

Step 1: Define Your Requirements

Product Specifications

Provide the following information about your product:

Production Requirements

Regulatory Requirements

Branding Assets

Step 2: CAD Engineering

Design Phase

Our engineering team uses SolidWorks to design your mold:

Cavity Design:

• Optimized geometry for your product shape
• Correct depth for target weight per cavity
• Appropriate draft angles for demolding
• Detail reproduction optimized for silicone casting

Tray Layout:

• Maximum cavity count within tray size constraints
• Uniform fill characteristics across all cavities
• Structural ribbing for tray rigidity
• Alignment features for two-piece molds (if applicable)

Pour Gate Design:

• Positioned for optimal material distribution
• Sized for your production volume and viscosity
• Designed for easy cleaning and maintenance

Your Review

You receive:

• Full CAD render — Photorealistic visualization
• Technical specifications — Cavity dimensions, tray size, durometer
• Production estimates — Expected output per pour, cycle time
• Pricing quotation — Detailed cost breakdown

Review period: 3-5 business days for feedback and approval.

Step 3: Master Model Fabrication

Master Creation Methods

Surface Quality Standards

• Layer height: 50μm (0.05mm) for SLA printing
• Surface finish: a production surface finish set at DFM for high-detail applications
• Post-processing: IPA washing and UV post-curing

Step 4: Prototype Mold and Validation

Prototype Manufacturing

We manufacture a prototype mold using the approved master model. This prototype is shipped to you for testing.

Validation Testing

Adjustment Process

• Minor adjustments: Modify master and re-produce prototype
• Major redesign: Revise CAD design and restart process
• Approval: You confirm prototype meets all requirements

Step 5: Production Manufacturing

Manufacturing Process

1. Material preparation — Platinum-cured silicone formulation selected 2. Mold pouring — Silicone mixed, degassed, and poured over master 3. Curing — Controlled curing process (typically 4-8 hours) 4. Demolding — Prototype removed from master 5. Inspection — Dimensional verification and quality check 6. Documentation — CoC, MSDS, and weight verification chart prepared 7. Shipping — Carefully packaged and dispatched

Production Quality Control

Step 6: Delivery and Support

Documentation Included

Post-Delivery Support

• Technical support — Equipment compatibility consultation
• Production optimization — Recommendations for maximizing output
• Troubleshooting — Guidance on common production issues
• Mold modifications — Design changes for production adjustments

FAQ

Q: How long does the custom mold design process take? A: Typical lead time is after sample approval, depending on the job from requirement submission to production delivery.

Q: Can I request changes after approval? A: Yes, changes can be made at any phase. However, changes after master fabrication may incur additional costs.

Q: Do you offer rush production? A: Yes, rush scheduling is available for time-critical launches.

Q: What if the prototype doesn't meet my requirements? A: We work with you to make adjustments until the prototype meets your specifications.
