The skin layer and core layer of the molded product are formed using two types of materials via the same sprue.
Traditionally, molded products that were monochromatic can now be enhanced with the potential for expression and a sense of luxury through variations of two or more colors and patterns. By utilizing the same molds that were previously used, different designs such as two-color marbles, sandwiches, tortoiseshell, flowers, and stripes can be expressed through injection control, nozzle structure, and molding conditions. Additionally, it is also possible to accommodate special applications such as multilayer molding with different materials.

basic information
■Principle of Mixed Color and Sandwich Molding 《Sandwich Molding》 A method of forming the skin layer and core layer of a molded product using two types of materials through the same sprue. Injection Device A → Inject skin material When injecting into the mold, the part that comes into contact with the mold surface first cools and solidifies. ↓ Injection Device B → Inject core material The core material injected later is encapsulated inside the solidified skin layer. ↓ Enables two types of three-layer molding!

Applications/Examples of results
■Features of Sandwich Molding Method - Utilization in fields that could not previously be resin-molded through multi-material layered molding. - Covers the disadvantages of single material molding through multi-layer molding. - High added value through improved softness and fashionability. - By wrapping recycled materials from waste plastics, which cannot be used as surface materials, with new materials, it is possible to achieve both cost reduction and environmental measures.
