Sandwich Thermoplastic Injection Molds

New custom thermoplastic injection molding techniques are constantly being developed, and Aline Components has the expertise and the latest technology to meet the most exacting demands for precision plastic parts in the Tri-State Area. Sandwich molds add another innovative option for industries and product designers looking for new features and new levels of performance for their specialized components. The sandwich molding process is a multi-injection process that allows multiple types and colors of thermoplastic material to be nested within each other for plastic parts with a core matrix material and thin rigid outer layers.

The sandwich molds combine high levels of structural performance and low weight, with the core material handling shear loads and the thin outer layers taking the in-plane compressive and tensile forces. Other options include the insertion of interstitial barrier layers or the creation of a skin layer with a galvanized solid core.


The applications for products made from sandwich molds are also developing, with innovations that take advantage of the opportunity to combine different material properties. Products with flexible hinges, soft-grip handles and surfaces, or shock absorbing and acoustic dampening layers can all make excellent use of sandwich molding technology.

Aline Components is a premier thermoplastic injection molding company with extensive experience in the production of all types of plastic parts, offering a range of services few plastic manufacturers can match in Pennsylvania, New York, New Jersey, Delaware, and beyond. The company's knowledge of plastic types and the different injection molding technologies and methods allows Aline Components to recommend the best material and process for any type of production run, whether it requires short run hot molds, rapid prototyping, stack molds for large volumes of components, or specialized processes such as insert molding or sandwich molding.
