Insert Injection Molding

Insert injection molding: Insert molding refers to a molding method in which pre-prepared inserts of different materials are placed in the mold and resin is injected, and the molten material and inserts are bonded and solidified to form an integrated product.

Process flow:

In the insert molding process, the injection molding machine is usually only a part of the overall system. Inserts usually require orientation first, a task that can be accomplished with a vibrating table. The Insert is then placed into the mold by the end of arm tooling (EOAT), usually with the aid of a pre-positioning device to access the mold. After reaching the stage of finished parts, the ejection positioning is the most important step, and the repeatability of the mold opening action of the injection molding machine is crucial here. Once the Insert is closed in the mold, it is held in place by vacuum or mechanically (e.g. using slides). While the insert is being inserted, the previous finished part is ejected.

Technical Features:

1. The pre-forming combination of multiple inserts makes the post-engineering of product unit combination more rational.

2. The combination of the easy formability and bendability of the resin and the rigidity, strength and heat resistance of the metal complement each other to make a complex and exquisite metal-plastic integrated product.

3. Especially by utilizing the combination of the insulation of resin and the conductivity of metal, the molded products can meet the basic functions of electrical products.

4. For rigid molded products and curved elastic molded products on rubber sealing pads, after injection molding on the substrate to form an integrated product, the complicated work of arranging the sealing ring can be omitted, making the automatic combination of the subsequent process easier.
