Rubber Revolution

Your rubber outsoles can be taller, lighter, and cost less

Traditional Rubber Molding is Labor Intensive

Significant Preparation Before Rubber Production

  1. Rubber formulation and mixing

  2. Rubber kneading and compounding

  3. Drying and cooling

  4. Sheet stock production and cutting

  5. Manual placement of rubber in the compression mold

The preparation steps usually require more than 3 operators just to get the rubber materials ready

Rubber 2.0: Direct Rubber Injection Molding

Ready-To-Use Rubber Granules

Our rubber granules are pre-compounded, pre-vulcanized, pre-color, ready-to-use for direct rubber injection molding. This makes our customers’ life easy before the actual molding begins

Direct Granule Feeding

Simply feed the pre-compounded rubber granule produced by Goaflex into the rubber injection molding machine feeder. Minimal labor requires as everything is semi-automatic.

Automatic Rubber Injection

Rubber injection molding takes place as the high pressure nozzle inject the semi-molten rubber into the high temperature mold, which begins the rubber crosslinking. The machine also features automated de-molding process where

Deep Cut + High Wall, Now Possible

Rubber injection molding enables high-wall shoe outsole designs by injecting heated rubber into a closed mold under high pressure. This process fills deep, tall, and complex cavities more completely than traditional compression molding, delivering sharper details, consistent quality, and greater outsole design flexibility.

Rubber injection can improve output and cost structure by reducing steps, manual handling, waste, and re-work. The key upfront consideration is tooling investment and injection machine.

Reduce Labor, Waste, and Cost with Rubber Injection Molding

Traditional rubber outsole manufacturing requires multiple operators for compounding, sheet preparation, and material handling. Rubber injection molding automates much of the process, allowing one operator to manage multiple molds. Precision injection reduces rubber flash waste by up to 5% and can lower overall production costs by up to 15%.

Compression vs Injection Labor Comparison

Traditional Rubber Molding

Rubber stock preparation, cutting, loading into the mold

Manual mold opening, handling, de-molding

Rubber Injection Molding

Ready-to-use rubber granule go into the automated feeder

Automatic mold opening, manual de-molding

For a 6 mold production line, the rubber injection molding technology can reduce more 83% labor required.
