3.IML technology The outstanding features of in-mold insertinjection molding (IML) technology are: the surface is a hardened transparent film, the middle is a printed pattern layer, and the back is a plastic layer. Because the ink is sandwiched between, the product can prevent the surface from being scratched and resistant. It can rub and keep the color vivid for a long time. IML technology production process: IMLtechnolog y product effect: 1）   Diversification of printing appearance effects: By combining soft-touch transfer printing with printing technologies such as color and electroplating, various appearances can be realized. 2 ） The research and development of ultra-thin IML, the thinnest can reach 0.80mm, and the deformation is less than 0.5mm; the deformation of 6-inch battery cover is less than 1.0mm; the thickness of local glue reduction can be 0.6mm. development trend: In the existing equipment and process flow of IML technolog...

The structure of the hot runner mold is generally the same as that of the thin nozzle. The biggest difference is that the runner is located in one or more hot runner plates and hot nozzles with constant temperature. There is no cold material demoulding, the runner and gate are directly on the product. Therefore, the runner does not need to be demolded. This system is also known as the nozzleless system, which can save raw materials. It is suitable for the product that the raw materials are expensive and the product requirements are high. Hot runner system, also known as hot sprue system, is mainly composed of hot runner sleeve, hot runner plate and temperature control electric box. There are two types of hot runner system: single point hot sprue and multi-point hot sprue. Single-point hot sprue is to use a single hot sprue sleeve to inject molten plastic into the cavity directly. It is suitable for plastic molds with single-cavity and single-gate; multi-point hot-gate ...

First, injection mold 1. If the mold cavity is not processed well, if there are scars, micro holes, wear, roughness, etc., it will inevitably reflect on the plastic part, making the plastic part poor in gloss. In this regard, the mold must be carefully processed to make the surface of the cavity Small roughness, polishing chrome plating if necessary.  2. If the surface of the cavity has oil stains, water stains, or too much release agent, the surface of the plastic part will be dark and dull. In this regard, you should remove the oil stains and water stains in time, and limit the use of mold release agents. 3. If the demolding angle of the plastic part is too small, it is difficult to demold, or the force is too large during demolding, so that the surface gloss of the plastic part is the best. In this regard, the demolding angle of the plastic part should be increased. 4. If the mold exhaust is poor, too much gas stays in the mold, which also causes poor gloss. For this,...
