How much does the mold opening and closing speed of the injection molding machine affect production?
 
In the field of injection molding production, the mold opening and closing speed of the injection molding machine seems to be just a simple mechanical action parameter, but in fact it is like the pair of wings in the “butterfly effect”, which has a profound and extensive impact on the entire production process, from production efficiency to product quality to mold life, it is closely connected.
1. The “catalyst” for production efficiency
The speed of opening and closing the mold directly determines the speed of injection molding production.High-speed mold opening and closing can greatly shorten the molding cycle of a single product, creating more output opportunities for enterprises per unit time.Imagine that in a busy plastic daily necessities production factory, the mold opening and closing speed of the injection molding machine has been increased from the traditional 8 seconds each time to the advanced less than 3 seconds, which means that several more injection cycles can be completed per minute.Calculated according to the production time of 16 hours a day, over time, the output will achieve leapfrog growth, allowing enterprises to seize the opportunity in the fierce market competition, quickly respond to customer order needs, and enhance their own supply capacity and market share.
2. The “gatekeeper” of product quality
Too fast or too slow mold opening and closing speed may lay hidden dangers for product quality.When the mold opening and closing speed is too fast, the mold will produce a greater impact force during the high-speed opening and closing process, which can easily lead to loosening and deformation of the mold parts, thereby causing the product to have appearance defects such as flying edges and burrs. For the production of some precision electronic plastic parts, these minor defects are enough to make the product a defective product.On the contrary, if the mold opening and closing speed is too slow, the cooling time of the plastic melt in the mold cavity will be extended, which may cause difficulties in product release, strain, deformation and other problems during release, especially when injection molding large-scale thin-walled plastic products, such quality problems will be more prominent, seriously affecting the structural integrity and appearance flatness of the product.
3. The “barometer” of mold life
As the key equipment for injection molding production, molds are expensive, and their service life is directly related to production costs.Unreasonable mold opening and closing speed will cause fatal “internal injuries” to the mold.The speed is too fast, and the mold frequently undergoes severe shocks, just as a person suffers from high-intensity vibration for a long time, and the wear of internal parts is aggravated. Components such as guide posts and sliders are prone to fatigue and wear, shortening the normal service life of the mold.The opening and closing speed is too slow. Although the impact is reduced to a certain extent, it will cause the mold to be in a high temperature and high pressure environment for a long time, accelerate the thermal fatigue of the mold material, and also reduce the life of the mold. , Increase the economic burden of frequent mold replacement by enterprises.
In summary, the mold opening and closing speed of the injection molding machine is by no means an isolated parameter, it is one of the key factors affecting the production of injection molding.In the production process, enterprises must fine-tune the mold opening and closing speed based on product characteristics, mold quality and equipment performance, so as to find the best balance between production efficiency, product quality and mold life, so as to maximize the benefits of injection molding production.
