What problems should be paid attention to in the process conditions of blow molding processing? -- Kunshan Fulong Plastic Hardware Co., LTD
The intention of the adjustment of the process conditions is to ensure that the wall thickness of the product is as uniform as possible and the weight of the product is as small as possible (to reduce data consumption) on the basis of satisfying the requirements of the product 樶. The reasonable method of process parameter setting is to combine experience with numerical analysis technique. For example, children's blow molding tables and chairs are also completed by blow molding.
1. Input the parameters of the influence of each stage on the wall thickness dispersion of the billet;
2. Using artificial experience, adjust the input parameters, repeat the process of steps ① to ③, and ensure that the wall thickness of each part of the product is minimized as much as possible while reaching the minimum wall thickness.
3. Using established computer models, simulate situations such as blow molding molds, cutting blanks, and clamping plates;
4. Analyze and compare the effects of multiple process plans, after all, determine the optimized process parameters. Stretching blow molding, also known as biaxially oriented blow molding, is a method of mechanically stretching the preform in the high elasticity state of polymers, and using compressed air to radially inflate (stretch) the preform to form packaging containers. There are one-step and two-step methods for stretch blow molding.
5. Analyze the imitation effect obtained, and through computer simulation, identify which parts of the wall thickness do not meet the requirements and which parts have excessive wall thickness;
