Plastic molds don't last as long and need protection against scratches
Plastic resin molds are a popular choice for crafters due to their affordability and ease of use. However, one significant drawback of plastic molds is their limited durability. Plastic molds are prone to scratches and can degrade over time, especially when compared to silicone molds. Twisting or warping a plastic mold can occur during the demolding process, which can be challenging due to the resin's tendency to stick to the plastic.
To prolong the lifespan of plastic molds, it is crucial to take extra care in handling and maintenance. This includes protecting the mold from scratches, as scratches can create crevices for the resin to seep into, making removal even more difficult. Crafters need to be gentle when removing the resin from the mold to avoid twisting or warping the plastic.
Additionally, using a mold release agent or a release coating is highly recommended. A release agent acts as a barrier between the resin and the mold, facilitating easier demolding and reducing the risk of damaging the plastic mold. Some crafters have suggested using household items such as cooking spray or Vaseline as release agents, but these options can be messy. Commercial mold release products, such as the Castin' Craft mold release, are also available and can provide better results with less residue.
While plastic molds may be more cost-effective upfront, their shorter lifespan and the need for extra care and protection against scratches can make them less economical in the long run. Silicone molds, on the other hand, offer greater flexibility, durability, and ease of use, resulting in a more enjoyable crafting process and a better return on investment.
Ultimately, the choice between plastic and silicone molds depends on personal preference, budget, and the crafter's level of dedication to the hobby. However, considering the limitations of plastic molds regarding longevity and the need for scratch protection, it is essential to weigh the advantages and disadvantages of each type of mold carefully before making a decision.
