The selection of mold materials is an important issue in mold design and manufacturing, which directly affects the manufacturing process of the mold, the service life of the mold, the molding quality of the plastic parts and the processing cost of the mold. Because of this, domestic and foreign scholars have developed new mold steels

In the production process, tools are subject to normal wear and tear. It is certain that quality management control in daily production will play an important role in the assurance of tool quality, which mainly covers the following aspects: Effective data management, including production data, process data and drawing documents: Effective management of production data,

Over the past years, substantial advancements have been made in injection molding CAEsoftware. What started out as a tool to give designers a general idea of how a simple plastic part will fill, can now accurately analyze packing, cooling, warpage, fiber orientation in any complex part geometry and conditions in the mold. Identifying Problems in the Mold

Customers may not be very careful about the use of the hot runner system. Today, We would like to talk to you about the injection pressure when choosing a hot runner system. Injection pressure loss in hot runner systems cannot be ignored. Many hot runner mold users have a misconception that the plastic solution in

The shell of many common items in our life is basically made of plastic, such as mobile phone shell, refrigerator shell, computer shell, air conditioning shell, etc. All of them are produced by injection molding. The shell of a product is also a link that consumers come into contact with the product, regardless of the

The production process of a set of plastic molds is not a one-step process. It is necessary to grasp the structural design of the product well, so as to avoid many problems in the subsequent production process, such as shrinking and flashing. So, what issues should you pay attention to when making molds? Don’t just

In order to avoid unnecessary waste of time and trouble in mass production, it is necessary to pay patience to adjust and control various processing conditions, find out the best temperature and pressure conditions, and develop standard test procedures, which can be used to establish daily working methods.   Check whether the plastic in the

The venting slot serves two purposes: 1. Expel air from the plastic injection mold during the injection process of the molten plastic material; 2. Get rid of the various gases produced during injection molding processing. The setup of venting slots is of great importance, especially for thin-walled products or the locations far away from the

Usually, the surface of plastic products obtained by this injection moulding method has good gloss and beautiful color, but in the actual injection moulding production process, many products produced by injection moulding factories have relatively large defects in color and gloss. Besides the hard factors such as plastic raw materials, colorants and the surface gloss

  Surface roughness means there is a lack of precision in the surface of a molded part, or an inconsistent level of precision all over the surface, e.g. some areas are glossier than the rest. The main reasons for surface roughness might lie in the injection molding machine, the mold, the process or the material.
