Frequently Asked Questions (FAQs)

#

What are the main types of rubber molding processes?

You have three primary types of rubber molding processes: rubber injection molding, rubber compression molding, and rubber transfer molding. Each process has its unique advantages and is suited for different types of products and production volumes.

#

What are the benefits of rubber injection molding?

Rubber injection molding offers high precision, consistent quality, and shorter cycle times. It is ideal for producing complex part designs and reduces material waste, making it cost-effective for high-volume production.

#

How does rubber compression molding differ from injection molding?

Rubber compression molding involves placing uncured rubber into a heated mold and applying hydraulic pressure. It is simpler, with lower tooling costs, and is suitable for large, thick parts, but it can have longer cycle times and may require additional finishing steps.

#

What are common issues in rubber injection molding and how can they be resolved?

Common issues include short shots, shrinkage, excess flashing, warpage, and brittleness. These can be resolved by adjusting parameters like shot size, melt temperature, fill speed, and clamp force, as well as optimizing mold design and process conditions.

#

How do you maintain the quality and longevity of rubber molds?

To maintain quality and longevity, regular mold maintenance is crucial. This includes cleaning, polishing, and occasionally replacing molds to prevent wear and tear. Proper storage and handling of molds also help extend their lifespan.
