TPE injection molding is an efficient cyclic processing method. Its core process involves heating and plasticizing granular TPE raw materials in the barrel of an injection molding machine until they reach a molten state, and then injecting them into a closed mold cavity at high pressure and high speed. The molten material cools and solidifies in the mold cavity, forming the desired shape, and the part is ejected after the mold is opened.

TPE (thermoplastic elastomer) extrusion molding is an efficient continuous processing method. Materials are added to the extruder through a hopper and, under the rotation of the screw, are heated, melted, and plasticized into a uniform viscous flow. The melt is then pushed under pressure through a specific die to obtain the desired cross-sectional shape, followed by cooling and shaping, pulling, and cutting, ultimately producing pipes, profiles, or sheets. The key to this process lies in precisely controlling the temperature at each section, screw speed, and cooling rate to ensure dimensional stability, smooth surface, and consistent elasticity and physical properties of the products. It has high production efficiency and is suitable for large-scale manufacturing.

TPE (thermoplastic elastomer) double-shot injection molding is a process in which TPE material is molded together with hard plastics such as PP, ABS, or PC, or different types of TPE materials, in two separate injections using a two-color/multi-color injection molding machine. Its core advantage lies in the integrated combination of elastic and rigid properties, allowing for dual optimization of product functionality and tactile feel without the need for secondary assembly.

TPE toughened rigid plastic is a new composite material made by adding thermoplastic elastomers (TPE) to traditional rigid plastics. It can toughen materials like PP, PS, 475, ABS, combining the rigidity of hard plastics with the elasticity of TPE. Through a special process, the TPE is dispersed in the rigid plastic matrix in the form of microbeads or a network, forming a 'sea-island structure,' which effectively enhances the impact strength and toughness of the material.

TPE secondary injection molding is an advanced composite molding process that perfectly combines TPE material with hard plastics (such as PP, ABS, PC, etc.) through two-step injection molding, resulting in a composite product that is both functional and comfortable. The process first injects the hard plastic to form the product’s skeleton, and then injects TPE material into specific areas to create a soft outer layer or tactile regions.
