How to eliminate the color difference of masterbatches during injection molding production Color aberration is a common defect in masterbatch injection molding, and it is not uncommon to see batch scrapping of injection molding machine due to color difference of matching parts. There are many factors affecting the color difference, including the raw material resin, masterbatch, mixing of masterbatch and raw material, injection molding process, injection molding machine, mold, etc. Because of the wide range

How to set injection molding parameters? 1.Pre-confirmation and preparatory setting (1) Check whether the material drying, mold temperature and heating cylinder temperature are set correctly and reach the processable state. (2) Check the action and distance settings for opening and closing the mold and ejecting. (3) The injection pressure (P1) is set at 60% of the maximum value. (4) Hold pressure (PH) is set at 30% of the maximum value. (5) Injection speed (V1) is

Injection molding encountered these four common problems, how to solve? A, the solution to the bubble phenomenon in the injection molding process According to the causes of bubbles, the following countermeasures are available to solve the problem. 1. When the wall thickness of the product is larger, the cooling rate of its outer surface is faster than that of the central part, therefore, as the cooling proceeds, the plastic resin in the central part shrinks

Application fields and advantages of low pressure injection molding process Low pressure injection molding process is a system packaging process that injects hot melt materials into molds at a very low injection pressure (1.5~40bar) and rapidly solidifies them for molding (5~50 seconds). The system consists of materials, molds, equipment and application technologies. It is mainly used for packaging and protection of precision and sensitive electronic components, including printed circuit boards (PCBs), automotive electronic products, mobile

Eight Maintenance Points of Injection Molding Machine Manipulator 1: Guide rail and bearing The guide rails and bearings at all shafts shall be kept clean and well lubricated. If the manipulator is operating in a dusty environment, the guide rail needs to be cleaned frequently. If you find any metal chips or powder, it may indicate poor lubrication. In order to ensure proper lubrication, it is critical to have an appropriate linear guidance system. Most

Precautions for injection molding products The injection mold process is well controlled, and the ultimate goal is to make good molded products. What matters should be paid attention to for injection molded products? 1. No defects are allowed on the product surface: lack of material, charring, top white, white line, peak, blistering, whitening (or cracking, breaking), baking marks, wrinkles. 2. Weld line: generally, the weld line length of round perforation is not more than 5mm,
