In Mold Injection Molding: In Mold Decoration, also known as IMD (In Mold Decoration), is an internationally popular surface decoration technology. It is mainly used for decoration and functional control panels of household appliances, automotive instrument panels, air conditioning panels, mobile phone shells/lenses, washing machines, refrigerators, and other applications.

Firstly, the injection pressure should be greater than 25MPa; Injection speed greater than or equal to 300mm/s; The dimensional accuracy of the product is 0.001mm; The coefficient of standard deviation (rate of change) of product quality is less than 0.1%; Precision of opening and closing positions: opening ≤ 0.03mm, closing ≤ 0.01; The injection position accuracy (pressure maintaining end point) is less than 0.03mm; The force balance of the pull rod is less than 1%; The precision of the pre molded position is less than 0.03mm; Balance degree A of fixed and dynamic templates: less than 0.03mm when the locking force is zero; B: less than 0.005mm when the locking force is greater than z; The temperature control accuracy of the barrel and screw is less than ± 0.5 ℃.

Precision stamping parts workshops and molds primarily rely on external forces such as plates, strips, pipes, and profiles to achieve plastic deformation or separation, obtaining the required shapes and workpiece (stamping) forming methods and standards. Stamping and casting are plastic processing (or pressure processing), abbreviated as casting and known

Precision injection molding, strictly speaking, refers to the dimensional accuracy of plastic products produced through injection molding machine equipment, which can reach below 0.01mm, usually between 0.01-0.001mm in size. Precision injection molding is mainly used in industrial and civilian products such as aerospace, automotive components, precision instruments, sports equipment, testing tools, etc.

There are various types and complex shapes of precision stamping parts for automobiles, and some adverse phenomena often occur during stamping production. The middle cover bracket is a key load-bearing connector of the integrated dashboard assembly in the car cab, and is an important component to ensure the stable and reliable use of various automotive instruments.

During the forming and punching process of precision stamping parts, due to external factors such as strength, the knife can be split in one step. When dividing the knife, it is particularly important to pay attention to the functional stability of the coil material, which requires uniform stress and a common strength of the coil material
