The skin layer and core layer of the molded product are formed using two types of materials through the same sprue.
Traditionally, molded products that were single-colored can now be enhanced with the potential for expression and a sense of luxury through variations in two or more colors and patterns. By using the same mold that was previously employed, 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 multi-layer 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 cools and solidifies first. ↓ Injection Device B → Inject core material The core material injected later is encapsulated inside the solidified skin layer. ↓ This enables two types of three-layer molding!

■Characteristics of Sandwich Molding Method - Utilization in fields that could not previously be resin-formed through multi-material layered molding. - Covers the disadvantages of single material molding through layered 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.
