Warpage in rubber injection molding refers to the deformation or distortion of a molded rubber part from its intended shape or dimensions. This can be caused by a number of factors, including:

1. Improper mold design: The mold design may not properly account for factors such as shrinkage or material flow. This can lead to uneven pressure distribution and result in warpage.
   
2. Incorrect processing parameters: The temperature, pressure, and injection speed used during the molding process can also affect the quality of the final part. If these parameters are not properly set, it can lead to uneven curing and warpage.
   
3. Material selection: The type of rubber material used can also contribute to warpage. Different types of rubber have different shrinkage rates and material properties, which can affect the final shape and size of the part.
   
4. Part geometry: The shape and complexity of the part being molded can also impact warpage.
   

To prevent warpage in rubber injection molding, it is important to carefully consider all of these factors and to optimize the mold design and processing parameters accordingly.

Some effective strategies to reduce warpage include optimizing mold temperature, using a suitable gating system, and ensuring even pressure distribution during molding. Additionally, conducting testing and experiments to determine the optimal settings for a particular part or material can help to prevent warpage and ensure high-quality molded rubber parts.

The injection velocity can have an effect on rubber warpage in injection molding, although it is just one of several factors that can contribute to warpage. The impact of injection velocity on warpage depends on the specific part design, material properties, and processing conditions. The injection velocity affects the flow behavior of the rubber material inside the mold cavity. Higher injection velocities can result in more turbulent flow, which can lead to increased material orientation and alignment. If this orientation is not uniform, it can cause differential shrinkage and contribute to warpage!
