Should I Use Polyurethane Mold Rubber or Silicone Mold Rubber?
you’re in the planning stages of your mold making project and you need to decide which rubber is more suitable for your process: polyurethane mold rubber or silicone mold rubber? each option has advantages and disadvantages and there are a wide variety of options in each of the product lines themselves (e.g., there are over 30 individual options within the polyurethane rubber line – they

shore a urethanes as molds. our selection of shore a urethanes can be used as flexible materials to create molds with negative angles. unlike composite molds which cannot release parts with negative angles, the soft, pliable shore a urethane can be bent back (or even cut off) for easier release.
cast urethane . urethane casting is a versatile process for fabricating plastic and rubber parts at low to medium production volumes. similar to injection molding, urethane casting uses a two-part mold where the two halves combine to create a void that the urethane is poured into until a cured part is formed.

Urethane Casting Comparison to Plastic Injection Molding
urethane casting can even produce parts with more strength than injected molded parts, and the silicone molds have the ability to reproduce very fine details in surface finish. considering all these similarities and differences, the deciding factor usually comes down to volume. for high volumes, injection molding will be advantageous.
