PROCESSTenderate is a high performance compound that consists of TPE(technical thermoplastic elastomers) and functional additives specially designed and engineered for expanded foam application. By the novel process of injection-molded expansion, Tenderate transforms into designed shapes inside the mold through precise control to deliver final expanded form that carries the mechanically engineered properties and intended finish.
compounding & pellet process
After the mixture of raw materials and chemical additives, they are moved over to the kneading machine and kneaded under high temperature inside the chamber. After this process, they are taken over to the rolling machine.
2. Kneader Mixing
The primarily finished copolymer is then moved over to the preheated rolling machine to be blended. To make the mixing of raw materials to be evenly balanced, they are flipped over three times and are put through rolling machines with different sized pins. The complete mix is then moved to the pellet manufacturing process.

Prior to be used in the Injection Molded Foam process, the mix from extruder goes through a cooling process then pelletized into small granules size less than 3mm then stored in separate labeled packages.
injection mold process
5. Injection condition setting
Compounded granules are processed into final product by Injection Molded Foaming process. To achieve the desired finish and include the engineered mechanical properties, injection process conditions have to be carefully optimized when controlling Crosslinking initiation and foaming gas evolution temperature, preventing any unwanted internal stress during expansion process.
6. Injection & curing
Injector melts down the compounded granules then delivers the molten mixture into a mold cavity at optimized pressure, temperature and time. After preset curing conditions, crosslinking is completed and gas evolution starts. With depressurization and opening of the mold, expanded foam part is then demolded. Part stabilization process follows for quality control.
