How To Control The Burrs Of Silicone Rubber Products

When it comes to silicone product manufacturing, precision is key. One common issue that manufacturers like us at DX face is the formation of burrs on silicone rubber products. Burrs are small, often sharp, protrusions that can occur at the edges or seams of a product during the molding process. Not only can they affect the functionality and aesthetics of the product, but they can also lead to customer dissatisfaction. Therefore, controlling and minimizing burrs is essential for maintaining the high quality of our custom silicone products.

Understanding the Causes of Burrs

Before we delve into the solutions, it’s important to understand why burrs form. Several factors contribute to their development:

  • Mold Design: Poorly designed molds with improper alignment can cause excess material to seep out, creating burrs.
  • Material Viscosity: The viscosity of the silicone material plays a role. If it’s too low, the material can easily flow into unwanted areas.
  • Curing Time: Insufficient curing time can result in incomplete setting of the material, leading to burrs upon demolding.

Strategies for Burr Control

Here are some effective strategies to control the formation of burrs in silicone rubber products:

1. Optimize Mold Design

Ensure that the molds are designed with tight tolerances and smooth surfaces to prevent excess material from escaping and forming burrs.

2. Adjust Material Viscosity

Work with your silicone product manufacturer to find the optimal viscosity for your material that minimizes burr formation while still allowing for easy flow and filling of the mold.

3. Fine-Tune Curing Times

Curing times should be adjusted according to the product size and thickness to ensure complete setting of the material without over-curing, which can also lead to burrs.

4. Implement Post-Processing Techniques

Sometimes, despite our best efforts, burrs can still occur. In such cases, post-processing techniques like trimming, sanding, or tumbling can be used to remove them.
