Borracha de Alta Consistência (HCR)

HCR silicone is supplied in solid form.

Vantagens:

• Good mechanical strength
• Adequado para peças de maiores dimensões
• Cost-effective for certain applications

Aplicações:

• Vedantes industriais
• Componentes grandes de silicone

Silicone Hardness Selection

Silicone hardness is generally measured by Shore A.

Typical choices:

Dureza	Candidatura
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
• Durabilidade
• Desempenho de vedação

3. Prototype Development: Turning Ideas into Real Products

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

Prototype development helps verify:

• Product appearance
• Experiência do utilizador
• Functionality
• Desempenho da montagem

Common prototype methods include:

3D Printed Models

Utilizado para:

• Shape verification
• Design evaluation

Vantagens:

• Fast
• Low cost

Limitations:

• Usually cannot fully represent silicone properties

Silicone Prototype Molding

For functional testing, silicone prototypes are preferred.

They can evaluate:

• Suavidade
• Elasticidade
• Grip feeling
• Desempenho de vedação

This step is especially important for:

• Dispositivos médicos
• Wearable products
• Consumer products

4. Concepção de moldes e ferramentas

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

A well-designed mold determines:

• Product quality
• Eficiência da produção
• Manufacturing cost

Important mold design considerations include:

Parting Line Design

The mold separation line should minimize:

• Flash

• Post-processing requirements

Venting System

Proper ventilation allows trapped air to escape during molding.

Poor venting may cause:

• Air bubbles
• Preenchimento incompleto
• Defeitos superficiais

---

Gate Design

The injection gate controls how silicone flows into the mold cavity.

Correct gate design improves:

• Material distribution
• Qualidade da superfície
