Shore A 10-30	Soft baby products, flexible parts
Shore A 30-60	General consumer products
Shore A 60-80	Industrial components

Selecting the correct hardness affects:

• Product feel
• Durabilidad
• Rendimiento de estanqueidad

3. Prototype Development: Turning Ideas into Real Products

Before investing in mass production tooling, startups usually need prototypes.

Prototype development helps verify:

• Aspecto del producto
• Experiencia del usuario
• Functionality
• Rendimiento del montaje

Common prototype methods include:

3D Printed Models

Se utiliza para:

• Shape verification
• Design evaluation

Ventajas:

Silicone Prototype Molding

For functional testing, silicone prototypes are preferred.

They can evaluate:

• Suavidad
• Elasticidad
• Grip feeling
• Rendimiento de estanqueidad

This step is especially important for:

• Productos sanitarios
• Wearable products
• Consumer products

4. Diseño de moldes y utillaje

The mold is one of the most important investments in silicone manufacturing.

A well-designed mold determines:

• Calidad del producto
• Eficiencia en la producción
• Manufacturing cost

Important mold design considerations include:

Parting Line Design

The mold separation line should minimize:

• Flash
