Many Charger injection molding manufacturers focus on shell injection molding of mobile phone chargers, computer chargers and other home appliance chargers. They have advanced injection molding equipment and skilled operators, so they can receive many orders from all over the country every year. These manufacturers are familiar with every link of mold molding and master various mold molding techniques. Next, we will explore the importance of demoulding slope in the production of charger shells.
In the production process of charger shells, mold molding and demoulding operations are part of daily work, and demoulding slope is an important factor to ensure the smooth demoulding of plastic parts. The design of demoulding slope is to facilitate the demoulding of plastic parts and avoid scratching the product surface during demoulding. Its size depends on the shrinkage rate of plastic. The direction of demoulding slope should be determined according to the internal and external dimensions of plastic parts. For the inner hole of plastic parts, the slope should be based on the center of the mold, the size should meet the requirements of the drawing, and the slope should be marked along the bulging direction. The shape of the plastic part should be based on the big head of the mold cavity, the size should also meet the requirements of the drawing, and the slope should be marked along the reduction direction. After the mold is opened, the plastic part should remain on the core, and the demolding slope of its surface should be smaller than the demolding slope of the outer surface. The charger shell manufacturer will formulate a suitable demolding slope according to the characteristics of each product.
According to the charger shell manufacturer, the demolding effect of the product is also closely related to the injection speed. When setting the injection speed, the geometry of the mold, flow restrictions and other unstable factors must be considered. The speed setting requires a clear understanding of the injection molding process and materials, otherwise the product quality will be difficult to control. Since the melt speed is difficult to measure directly, the charger shell manufacturer usually calculates the melt speed indirectly by measuring the screw forward speed or cavity pressure.
