High Temperature Resistant Engineering Plastic High temperature engineering plastics are engineering plastics that retain high mechanical properties under high temperature conditions. This property is generally caused by its own special structure. With the continuous development of electronic equipment, the application of high temperature engineering plastics in this field has been expanding and becoming the material…
Reasons For The Formation Of Shrinkage Marks In Plastic Molds And Improvement Methods There may be one or more reasons for the formation of shrink marks, including processing methods, component geometries, material selection, and mold design. The choice of geometry and material is usually determined by the raw material supplier and is not easily changed.…
Four Factors Affecting The Fading Of Plastic Products Plastic colored products can be discolored by a variety of factors. The fading of plastic colored products is related to the light resistance of the pigment, the dye, the oxidation resistance, the heat resistance, the acid and alkali resistance, and the properties of the resin used. According…
Finished Mucous Membrane Possible Causes And Treatment Countermeasures (1) The filler is too full to reduce the injection dose, time and speed; (2) The injection pressure or the barrel temperature is too high to reduce the injection pressure or the barrel temperature; (3) The pressure keeping time is too long to reduce the holding time;…
Reasons For Failure Of Demoulding And Treatment Methods (1) The runner is too large to modify the mold; (2) The runner cooling is not enough to extend the cooling time or reduce the temperature of the tube; (3) The mold release angle is not enough to modify the mold to increase the angle;…
Injection Molding Machine Special Robot Classification For the robots used in injection molding, they can generally be divided into the following three types according to their functions: 1. Simple injection molding robot Simple injection molding robots can be divided into fixed mode program type and variable program type. Fixed-program injection molding machine manipulators cannot change…
Finished Mucous Membrane, Difficult To Demould Depending on the size and temperature of the molded product, when the mold release resistance is increased, mold release failure occurs. Although it is also affected by resin characteristics and molding conditions, the main reason is the shape of the molded article and the structure of the mold. Of…
Type Of Plastic Molding 1.Injection molding The plastic material is first melted in a heating cylinder of the injection molding machine, and then a method of forming the melt by a reciprocating screw to push the melt into a cavity of the closed mold. It can not only produce high-precision, high-quality products under high productivity,…
Plastic Properties (1) Easy to process, easy to manufacture (easy to mold) Even if the geometry of the product is quite complex, it can be easily produced as long as it can be released from the mold. Therefore, its efficiency is far better than metal processing, especially injection molding products, through a process, can produce…
Key Points For Test Mode When we received a new mold and needed proofing, we were always eager to try out a result earlier and pray for a smooth process to avoid wasting work and causing trouble. But here we must remind two points. First, the mold is inspected on the mold as soon as…
