1. The mold length must be less than the spacing of the column to put the mold in smoothly. If the mold length is greater than the spacing of the column, if the width and height of the mold are both less than the spacing of the column of the machine, it is also possible […]

Four tips to improve the precision of thin-wall injection molding The application range of plastic parts is becoming more and more extensive, from simple tableware and kitchen utensils to complex mechanical parts and electronic product shells. However, for plastic parts with high precision requirements such as electronic product shells, the precision requirements should be paid

Why do plastic products crack? Do you know the reason? There are mainly the following reasons: Processing Excessive processing pressure, too fast speed, more filling, injection, and long holding time will cause excessive internal stress and cracking.Adjust the mold opening speed and pressure to prevent demolding cracking caused by rapid strong drawing of the parts.Appropriately

Analysis and solutions to warping deformation of plastic products Warpage refers to the deviation of the shape of the injection molded product from the shape of the mold cavity. It is one of the common defects of plastic products. There are many reasons for warpage, and it is often difficult to solve it by relying

【two】How to choose between two-color injection molding and in-mold injection molding​https://doi.org/10.1016/j.jmapro.2024.02.021 ​B. Products with multi-colored appearance and no surface treatment​The appearance material is hard glue in multiple colors and does not undergo surface treatment. Most of them are used in light-transmitting products.For example: keyboard buttons, mouse, mobile phone protective case, etc. As shown below: C,

01 The meaning of draft angle Structural design of plastic parts: draft angle Draft angle, as you can tell from the literal meaning, is the angle designed for the mold. To be precise, it is the mold ejection angle of the surface of the molding part in the direction parallel to the mold ejection direction,

The most commonly used chamfers are divided intoRoundandchamferRounding refers to connecting two curved surfaces of a part tangently through a rounded surface. A standard rounded corner usually uses a radius value R to represent its size. Structural design of plastic parts: chamfering Chamfering refers to connecting two curved surfaces of a part at an angle

Pre-molding action selection Depending on whether the injection seat retreats before and after pre-plastic feeding, that is, whether the nozzle leaves the mold, the injection molding machine generally has three options: Fixed feeding: the nozzle is always attached to the mold before and after pre-molding, and the injection seat does not move. Front feeding: The
