Daily Necessities Mould(FURNITUREMOULD) is a tool that is matched with plastic forming machines in the plastics processing industry to endow plastic products with complete configuration and precise size. Due to the variety of plastics and processing methods, the structure of plastic moulding machines and plastic products is complex and simple, so the types and structures of daily necessities mould are also varied.
The working conditions of daily necessities mould are different from those of cold dies. Generally, they must be operated at 150 C-200 C. Besides being subjected to certain pressure, they must also be subjected to the temperature. At present, the basic performance requirements of steel for plastic moulds are based on the use conditions and processing methods of plastic moulds: heat resistance, sufficient wear resistance, excellent machinability, good thermal stability, mirror surface machinability, heat treatment performance and corrosion resistance. Only in this way can the requirements of different moulds made in different fields be met and the machinery operate normally.
The defects of most injection moulded parts are caused during the plasticizing and injection stages of daily necessities mould, but sometimes they are also related to unreasonable design. The influencing factors include the type of injection port, the number of mould cavities, location and size, the design of the cold/hot runner system, and the structure of the product itself. Therefore, in order to avoid product defects caused by mould design, we need to analyze the daily necessities mould when making them.
After obtaining the test results of daily necessities mould, the operator usually needs to re-evaluate the specific conditions of the moulds so as not to add unnecessary cost and time in the process of modification. In most cases, in order to make up for the deficiencies in mould design, the operator may make incorrect settings without knowledge, because the parameter setting range required to produce qualified products is very small, and any deviation in parameter setting may lead to the quality of the final products far exceeding the allowable error range.
The purpose of the daily necessities mould test is to find out the optimized process parameters and mould design. Not just to get a good sample. This is very important. Even if the factors such as materials, machine settings or environment have changed, a stable and uninterrupted mass production environment can still be ensured.
