Rubber Injection Molding stands out as one of the most efficient methods for molding rubber, offering an optimized process with numerous advantages. This technique, along with injection-transfer molding, begins with streamlined material preparation to ensure consistency and quality.
The process starts with mixing rubber material in 500-pound batches. Once mixed, the material is stripped into continuous strips approximately 1.25 inches wide and 0.375 inches thick. These strips are then fed into a screw on injection molding machines. Here’s a breakdown of the key steps:
Material Preparation and Loading
The screw charges the machine's barrel with a predefined amount of material.
Injection and Curing
When the mold closes, material from the barrel is injected into the mold cavities and cured to create the final product.
This efficient process ensures consistent material flow and high-quality output.
Rubber Extrusion Molding offers several key benefits that set it apart from other methods:
Elimination of Pre-Forms
This process removes the need for pre-forms, a labor-intensive step that can lead to variability in weight and shape. By eliminating this step, the final product's consistency improves significantly.
No Operator Placement Required
Unlike compression or transfer molding, operator intervention to place pre-forms in the cavity or pot is not required, making the process faster and more reliable.
Improved Material Flow and Faster Curing
The injection screw pre-heats the material, reducing its viscosity for easier flow into the mold cavities.
The pre-heating and shearing action during injection also decrease curing time, ensuring the process is both efficient and cost-effective.
