Over Molding – Enhance Your Product
Stebro Mold is a leader in custom plastic overmolding. Overmolding is a injection molding process which a single part is created using two or more different materials in combination, it is a tyep of multi-material molding. Using two separate injection molds on the injection molding machines, two materials are bonded together during the overmolding process to form plastic parts and components with unique visual or ergonomic appeal. Traditionally, overmolding starts with injection molding a hard plastic resin that has a higher metling point. Then, once that part is cooled, another plastic resin (usually a soft material such as TPE, TPU or TPV) is injection molded over the first part. Sometimes called elastomeric overmolding, elastomer overmolding. Small touches of overmolded soft touch plasic can make a big impact on product value. Getting it right depends on the strength of the bond between hard and soft plastic, each material must be carefully selected to ensure a chemical compatibility, as well as a thermal compatibility.
With overmolding, you can improve the functionality, look, and bond strength of your product while saving time and reducing costs.
