Plastic injection molded parts surface UV treatment of attention After UV treatment, the surface of plastic injection molded parts can be brighter and not easy to be scratched. The main process is to spray a layer of transparent oil on the surface, which needs to be dried by UV light: Plastic injection mold manufacturing 1. Due to the UV paint curing speed, high production efficiency, through the UV curing, 30 minutes can; 2. Excellent coating

Commonly used thermosetting plastic moulds and their molding characteristics Thermosetting plastic mold has a large stiffness, elastic and plastic deformation under load, and the temperature has little effect on the stiffness, under the same load and temperature conditions, creep is much smaller than the thermoplastic mold; good heat resistance, the plastic parts are quite stable to heat after curing; good dimensional stability of plastic parts. Affected by temperature and humidity and molding shrinkage is small,

Calculation method of working dimensions of injection molded parts The working dimensions of injection molded parts are the dimensions of the molded parts directly used to form the plastic parts, mainly the radial dimensions of the cavity and the core, the depth dimensions of the cavity and the height dimensions of the core, the location dimensions between the core and the core, etc. Any plastic parts have certain geometric shape and size requirements, such as

Rust causes of injection mould and solutions: As we all know, injection molds are mainly made of tool steel. During work, they will encounter corrosive gases, water and other substances that cause rust. Plastic parts made of rusty molds often have quality problems, so we must find out the causes of rust in the molds and solve them. Reason 1: When the mold raw materials are overheated, they will produce volatile gases, which are mostly

Several Common Injection Molding Processes for Mold Injection Mold injection molding is used in many plastic products, and the most common process in plastic molding is mold injection molding. Plastic is a very common material in life, and the products made from it are particularly popular. What are the most common injection molding processes in the mold injection molding process? 1、 Injection molding is also called injection molding. The factors that affect the quality of

How to reduce the harm of mold temperature machine to product quality? The injection mold temperature machine is used to control the mold temperature of the injection molding machine and heat the oil or water to the temperature required for product molding. 1. The plastic has no physical quantity of heat shrinkage and cold shrinkage, and some undesirable defects such as shrinkage, bubble, crack, deformation, crazing, poor lightness, unsmooth, and flaw are often seen outside
