The surface of the runner must be polished to reduce flow resistance and provide faster mold filling speed. The size of the flow channel depends on the type of plastic, the size and thickness of the product. For most thermoplastic materials, the cross-sectional width of the splitter channel does not exceed 8m. Due to IMD products integrating decorative functionality, the graphics, text, and colors of the injection molded parts are formed in one go during injection molding, reducing the post processing process; In addition, IMD three-dimensional molding increases the freedom of design, with graphics, text, and colors in the plastic interlayer, which are wear-resistant and corrosion-resistant, and have bright colors. The printing pattern can be changed at any time without the need to change the mold.

he IMD phone case can reach 10-12m in size and 2-3m in size. On the premise of meeting the needs, the cross-sectional area should be minimized as much as possible to avoid adding debris to the diversion channel and extending the cooling time.

Mechanical processing mainly uses cutting machines to process metal materials. As is well known, molds are almost assembled from metal parts. To obtain parts that meet the requirements of the drawing,

3D complex shape design and diverse styles. The pattern, color, font, and logo are printed on the frequency carrier surface of silk or screen printing, formed into 3D shapes, and can create special styles of metal electroplating or natural materials according to customer needs. Some effects cannot be achieved by electroplating and painting. High yield rate. High pressure forming only has a lower mold and no upper mold.

Mechanical processing is the main method used for IMD phone cases. Therefore, mechanical processing is the type of processing with the highest workload.

With the rapid development of communication technology, mobile phones are widely used.

Process simplification: By using a one-time injection molding process, both molding and decoration can be achieved simultaneously, which can effectively reduce costs and labor hours, provide stable production, and reduce costs and labor hours. In the IMD process, only one set of molds is required, unlike other old alternative processes that require multiple sets of fixtures, which can remove labor and labor hours from one operation program, reducing system costs and inventory costs.
