Benefits of technology
This new technology allows for better quality plastic materials used in electronic devices such as screens without any visible signs caused from imperfections like water droplets on their surfaces when they are exposed outdoors over time due to temperature changes. It also enhances its durability against damage even if dropped onto them accidentally while being stored at high temperatures. Overall, this innovation provides technical benefits including improved appearance, increased luminous intensity, reduced costs associated with manufacturing processes, and more efficient utilization of energy resources.
Problems solved by technology
The technical problem addressed by this patented technology relates to improving the strength or durability of display devices used for electronic communication (such as smartphones). Specifically, current displays have limitations such as being too hard on their surface due to low impact resistance compared with traditional paper materials like plasterboard that were commonly found around them during manufacturing processes. This can lead to damage from droplets falling onto these surfaces while they shouldn’t happen. Additionally, replacing damaged parts requires extra effort and costs associated with purchasing new ones instead of just replacements themselves.

Embodiment Construction
[0028] A method for manufacturing a high-hardness plastic mobile phone screen and case, comprising the following steps:
[0029] (1) Secondary compression molding: First, close the injection mold and lock the first parting surface of the injection mold, and then move the clamping cylinder back by 0.2mm, so that the second parting surface of the injection mold has a certain mold opening. space, and then inject plastic raw materials into the injection mold. The second parting surface is opened by 0.2mm under pressure. After the injection is completed, the clamping cylinder advances and locks the second parting surface. After cooling, the mold is opened to obtain a molded part. plastic substrate;
[0030] (2) The plastic substrate is cleaned and dried for the first time by using the dry air after destaticization, and the dew point of the dry air is -40°C;
[0031] (3) The first soaking: soak the plastic substrate after the first cleaning and drying into the adhesive, so that a laye

Abstract
The invention provides a manufacturing method of a high-hardness plastic screen and a high-hardness plastic housing of a mobile phone, and a mobile phone screen and a mobile phone housing manufactured by the manufacturing method. The manufacturing method comprises the following steps: performing secondary compressing and forming to obtain a base plastic material; cleaning and drying the base plastic material through electrostatic eliminated drying gas for the first time; soaking in an adhesive for the first time; cleaning and drying the base plastic material covered with the adhesive through the electrostatic eliminated drying gas for the second time; soaking in enhanced liquid containing silicide, nanometer aluminum oxide and corundum for the second time; roasting; hardening; trimming. The product manufactured by the method is free of rainbow-like marks, high in light transmission rate, and high in density; the hardness of the product is up to 9H, and is equal to or beyond that of a traditional glass screen; in addition, the product is hard to break, so that the product can completely replace glass to be used as the screen of the mobile phone; compared with a glass material, the plastic is low in price, so that the cost of the mobile phone screen manufactured through the plastic is low, and as a result, the use cost of a user can be decreased.
