Custom injection molding is a versatile manufacturing process that allows for the production of intricate and complex parts with a high degree of precision. When designing parts for custom injection molding, it’s essential to consider various factors to ensure the success of the final product. One such factor is the thickness of the material used, particularly when dealing with thermoplastic elastomers (TPEs) or thermoplastics vulcanizates (TPVs).
Avoiding Warpage with Proper Thickness
To avoid warpage, especially for flat or long parts, the thermoplastic elastomer/thermoplastics vulcanizates should be less thick than the substrate. This is because these materials can have a higher shrinkage rate during the cooling process, which can lead to undesirable warping or distortion of the final part. By keeping the TPE/TPV thickness lower than the substrate, the risk of warpage can be significantly reduced, ensuring a high-quality and consistent end product.
Overmolding Considerations
Another important aspect of custom injection molding is the process of overmolding, where one material is molded directly onto another. Overmolding requires mechanical or chemical bonding to the substrate. Therefore, the choice of overmolding materials should allow for this. The compatibility between the materials is crucial, as it ensures a strong and durable bond, preventing the overmolded component from separating from the substrate during use.
