  Insert molding is a kind of integrated molding method, in which the pre prepared special-shaped material insert is put into the mold, and the resin is injected after the mold is closed, so that the molten resin and the insert are connected and become solid, so as to make the special-shaped material.   The insert molding applications   are as follows:   1. Digital battery box products The base of the battery box is made of plastic, but four L-shaped metal inserts should be implanted in the front part of the battery box to achieve conductive contact and other functions. The four L-shaped metal inserts in the battery box can be called golden fingers, whose main function is to make the circuit conduct after contacting with the power spring. The structure of the four gold fingers in the cell slot is the same, and the relative position accuracy in the plastic matrix should be ensured after forming. Therefore, it is necessary to improve the insert structure on the premise...

  Is the injection molding process complicated? Where is the complexity? 1.The complex geometric properties of molds and parts Injection molded parts are usually thin-walled structures with complex shapes. The thin wall structure and high-speed injection speed together lead to high flow rate and high shear rate, and these complex viscosity characteristics with the material will cause a huge change in the viscosity of the material during the filling process. The mold has two main functions in the intro to injection molding process: ①Form the shape of the part to be produced; ②Make the mold cool down as soon as possible. Generally speaking, an 3d printed injection mold tooling is a complex structure with a complex mold core and ejection system. This complex structure will affect the location of the cooling water channel, and the location of the cooling water channel in turn will cause changes in the injection mold tooling temperature. These changes will affect the viscosity of the ma...

 Low-Volume Production Advanced Prototyping Market Testing Cast molding refers to the processing process in which liquid raw materials are poured into a mold and cooled and solidified at room temperature. Zhongde has many years of casting experience. Our experienced engineers can accurately analyze whether the product is suitable for casting products according to the product structure. For example, Zhongde will offer and recommend reusable metal casting molds for customers who need mass production of making identical products. The reusable metal casting molds are useful since they can be used repeatedly. Zhongde provides casting for different metal casting molds with 3D printing such as silicone casting molds, steel casting molds, aluminum casting molds, and brass casting molds. Zhongde also focuses on different plastic mould casting like TPE casting, PU urethane casting, and polymer cast molding. Advantages of Cast Molding Low-volume production Low-volume production High accurate ...

 More faster, more flexible, and lower-cost Create almost any shape of objects 3D printing (3DP) is a kind of rapid prototyping technology. It is advanced prototype engineering that uses powdered metal or plastic and other bondable materials to construct objects based on digital model files by printing layer by layer. Zhongde offers 3d printing prototyping service and 3d prototype solutions to meet your special   needs, such as 3d printed molds for injection molding. Instead of being replaced by 3d rapid prototype printing , our injection mold tooling is from 3d printed molds, with low prototype cost.   Types of 3D Printing Fused Deposition Modeling Fused Deposition Modeling Generally speaking, FDM uses high temperature to melt the material into a liquid state, extrude it through the print head and solidify it, and finally arrange it in three-dimensional space to form a three-dimensional object.   Learn More >   Selective Laser Sintering Selective Laser ...
