Alternate Injection Molding Alternate injection molding alternately injects the same plastic component of two different colors into the same cavity. Both colors are placed in a special mixing nozzle before entering the mold. The two-color components are mixed to form a color effect. The two colors can be purposefully mixed to configure. In the alternate…
DetailsComposite Injection Molding And Core Retraction Process In the core retreat production process, the hollow portion of the mold is first closed and later reopened using a sliding core or slider within the cycle. When producing a part with two components, the first injection molding stage first injects the prefabricated component and then opens the…
DetailsToughened Engineering Plastic The core-shell polymer particles are composite particles having a double layer or a multilayer structure composed of components having different chemical compositions or different aggregated forms. In 1957, Rohm & Haas of the United States first developed a core-shell polymer of the trade name K120. In the 1960s and 1970s, companies such…
DetailsAdvantages Of Multi-Component Injection Molding In multi-component injection molding, the components of the molded part are completely separated. All components are visible on the surface, reflecting the appearance and function of the part. For example, keyboard buttons, labeled switches, or handles with soft areas for added comfort. In addition to the ability to produce injection…
DetailsTwo-Station Mold In order to demold the part independently of the production process, a stripping station was integrated into the two-component molding. The mold is then rotated clockwise in steps of 120°. There is an opening on the side of the third station from which the gripper gripper can reach the closed mold, demold the…
DetailsFour-Station Mold Multi-layer plastic parts can be produced using four-station molds. This method is easy to implement when using recycled materials and barrier layers. The innermost layer is produced at the first station. Then, the mold is rotated 90° to the next station. At this time, the first component was injection molded using the second…
DetailsPush-Pull Injection Molding Such as injection molding process, this molding method can eliminate defects such as melt seams, voids, cracks and microscopic porosity in plastic parts, and can control the arrangement of reinforcing fibers. It adopts two main injection units and one double injection unit. Mold. In operation, the main injection unit pushes the melt…
DetailsLayer Injection Molding Layered injection molding is a molding process that combines the characteristics of co-extrusion molding and injection molding, which can arbitrarily produce a very thin layered state in complex parts. Layered injection molding simultaneously performs two different resin injections, which are layered in a co-extrusion die through a multi-stage co-extrusion die, and the…
DetailsMicrocellular Foam Injection Molding In the conventional structural foam injection molding, a chemical foaming agent is usually used, and since the foaming pressure generated is low, the produced article is limited in wall thickness and shape. Microcellular foam injection molding is limited by the use of supercritical inert gases. Microcellular foam injection molding uses supercritical…
DetailsMulti-Component Injection Molding Multi-component injection molding offers new possibilities for plastics processing, combining different materials or colors in a single molding. Production can be done in one process without the need for additional assembly or post-machine processing steps. Multi-component injection molding is a fully automated process with a high degree of flexibility, making it ideal…
