  HOT RUNNER MOULD In recent years, with the rapid development of the plastic industry and plastic moulds and the continuous improvement of general engineering plastics in terms of strength and precision, plastic products have been favored by more and more industries due to their low price and high performance. This has also greatly promoted the development of the mould industry, but with the continuous improvement of the quality and functional requirements of plastic products, especially the transparency and thickness of the product, and how to use a smaller machine to make a larger product, the manufacturing technology of the mould also has a great test. So many mould factories have also made a lot of improvements in the manufacture of moulds, and the use of hot runners is the most prominent. What is a hot runner? Hot runner technology is an advanced technology applied to the pouring runner system of plastic injection moulds. The hot runner uses heating to ensure that the plastic...

  PLASTIC BUCKET MOLD For  barrel mold s , the most important factor to consider is the consistency of wall thickness, as uneven wall thickness can lead to molding injection failure after a certain period of time. This requires the use of high precision tooling throughout the manufacturing process. In addition to wall thickness, the cooling system plays a crucial role in the upcoming molding injection period. The cooling system must be designed specifically for the plastic drum. Incorrect cooling water lines may affect the efficiency of the entire injection process. Plastic bucket mould technical points: 1, The reasons for uneven wall thickness of barrel caused by eccentric barrel mold (1) If the cooling water flows unevenly in each area of the core cavity of the barrel mold, it will cause the flow difference of the molten plastic, the hotter the area will be more liquid, the colder the area will be less liquid, thus making the barrel wall thicker in the hotter area. Under nor...

  How to Improve Precision of Mold Polishing Quality? In mold manufacturing process, forming portion of mold often requires surface polishing. Mastering  polishing technology can improve quality and service life of mold, thus improve quality of product. Mold polishing method and working principle Mold polishing usually uses oil stone strips, wool wheels, sandpaper, etc., so that surface of material is plastically deformed and convex portion of workpiece surface is removed to obtain a smooth surface, which is generally performed by hand. Method of super-fine grinding and polishing is required for high surface quality. Super-fine grinding and polishing is made of a special grinding tool. In polishing liquid containing abrasive, it is pressed against machined surface to perform high-speed rotary motion. Polishing can achieve a surface roughness of Ra0.008 μm. Common tools and specifications for mold polishing 1) Common tools for mold polishing include: sandpap...
