Knowledge of injection mold maintenance
The injection molding process of injection mold can be roughly divided into three steps, first, temperature mastery; Second, pressure mastery; Third, the cycle of molding.
Temperature mastery is divided into barrel temperature mastery, nozzle temperature mastery, mold temperature mastery. Different plastics have different active temperatures, so choose the barrel temperature for each plastic. The nozzle temperature will usually be lower than the barrel temperature, and the nozzle temperature will affect the performance of the product after molding. The mold temperature also has a great impact on the performance and quality of the product, and the mastery of the mold temperature depends on the crystallinity, the size and layout of the mold and other external conditions and internal conditions.
Pressure mastery is divided into two parts: plasticizing pressure and needle pressure. The plasticizing pressure requires a relatively high technical level, which is to change successively according to the quality of Hebei injection mold and the variety of plastic, while the injection pressure is to curb the activity resistance of the barrel, and give the filling speed and melt to grow the sponsorship
The realization of one injection process is the molding cycle. The molding cycle affects the task execution rate and the equipment application rate, so although the molding cycle time is shortened, compliance has been greatly maximized. The injection time and cooling time have a crucial impact on the quality of the product, so we need to shorten the cycle time while clad the quality of the injection mold.
Injection mold is used to glue finished products is the object, and this mold is to delicate is the configuration and people can apply to the product, so this mold or play a very big benefit, as far as this mold is concerned, it is also the need for maintenance, which is enough to make the application life of the mold double the long, spicy can also produce more products.
At the beginning, it is necessary to pay attention to the surface maintenance of the mold, that is, surface maintenance, can not let the surface of this mold be hindered, that is, can not let it erode, if the surface is affected, spicy Mo also has a very large impact on the quality of the product, so the surface maintenance of the mold is a must.
Secondly, it is necessary to regularly clean the Hebei injection mold, but also for the hygiene of the tube mold, for the product, the clean and hygienic mold out of the product is better, and this will not let the mold be contaminated.
It is necessary to inspect the parts of the mold to see whether the mold has failed, which is to avoid the mold failure and affect the product, so do a good job in these aspects of maintenance, Spicy Hebei injection mold can better carry out the work of the product.
The quotation of plastic mold generally includes the price of raw materials, the design price required for the design of the product, the processing price required for the processing mold, the appreciation tax required by the product, the mold trial price required by the mold trial, and the packaging and transportation price required by the packaging and transportation of the product. Let's talk about the plastic mold processing process
1. Accept the mission letter, the product designer or design team to provide the mission letter required to make the product. After inspection, the drawings are marked with the required data and the incident is noted.
2. Analyze the influence components encountered in plastic mold processing. Determine the cavity surface and parting surface affected in the processing of plastic molds, select the appropriate determination method, pay attention to the temperature grasp and the layout of part molding in the process, pay attention to the calculation formula, etc.
3. Network, rectify, analyze, inquire about the specific production steps of each step of the plastic mold data, and be familiar with the craftsmanship and fundamental data requirements of the product.
