(1) Moisture SensitivityAlthough PBT has low hygroscopicity, even small amounts of moisture in the material can cause hydrolysis at high temperatures, making the molded parts brittle. Therefore, it is...
(1) Causes of Difficulty in DemoldingExcessive Injection Pressure and Time: If the injection pressure is too high or the injection time is too long, it can lead to excessive filling, resulting in a lo...
When machining parts on CNC machine tools, a processing program is typically created first, which specifies the trajectory and process parameters for the part (such as spindle speed, cutting speed, et...
(1) Reasons for Testing Injection MoldsMold testing is the process of actually injecting plastic into a mold designed and manufactured for plastic products on an appropriate injection molding machine....
Gas assisted injection molding is a special injection molding technology developed on the basis of traditional thermoplastic injection molding technology, which is suitable for special performance req...
The main indexes of mold materials include service performance and process performance. For a mold, if the performance of the material is considered carelessly, a variety of mold materials may meet th...
Plastic residue refers to the plastic material sticked to the surface of the mold during the injection molding process, resulting in the surface of the product is not smooth, rough and uneven defects....
In order to improve production efficiency and reduce costs, small plastic parts are often designed as multi-cavity molds. The Runner System in the injection mold refers to the flow channel of the plas...
During the injection molding process, if the gate is improperly located, the injection molding pressure or holding pressure is too large and the product is not ejected smoothly, which will lead to pro...
Mold temperature refers to the surface temperature of the mold cavity in contact with the product. The choice and setting of mold temperature directly affects the filling of molten plastic, the coolin...
