Why is the injection molded part deformed?
For example, plastic gears and electrical shells are products that are widely used in our lives, and they also carry forward the benefits of being very stressful in our lives. For example, many plastic products used in our lives are required for plastic processing in Changzhou, and injection molded parts widely used in the machinery industry will also need to be processed for injection molded parts. Friends may encounter deformation when processing injection molded parts, so this time I will briefly talk to my friends about this question.
When it comes to the materials that are common in life, what do friends think of? I believe that many people have a lot of plastic products in their minds. Finished plastic products are now widely used in our lives, but in order to improve the performance of finished plastic products or the surface size of the product, we all need plastic processing. This kind of processing technology is ready to be used as injection molded parts processing, spicy as our common processing skills, what advantages does it have? Let's just make a brief inquiry.
Changzhou injection molding processing is a very wide application in our life, and the double injection molding process is a kind of injection molding processing technology. The double injection molding process refers to the injection molding of two different plastic materials through technical means, which has the following three convex advantages: First, the change of touch feeling. In the past, a little injection molding products could not reach the consumer's hand experience, and the dual injection molding process can simply improve the touch feel, and the product it creates is more like a well-crafted handicraft. Second, it is doubly easy to use. The product life of the products manufactured by the double injection molding process can not only be greatly improved, but also the strength and wear resistance of the product will be greatly improved. A visual blow. The pleasing appearance of the surface simply affects our desire to buy, and the dual injection molding process can double the specificity of the surface color of the product. The sales volume of products will be greatly increased.
Nowadays, the application of plastic products in our lives is becoming more and more extensive, so what are the plastic processing processes? Plastic processing extrusion, injection molding, molding, rotational molding, casting, dipping molding and other molding processes, these molding processes are based on the specific selection of different materials and products. 1. Extrusion: The grades used for extrusion manufacturing generally have a melt index of less than 1 and a MWD of medium to wide width. In the injection molding process, a low MI can achieve a suitable melt strength. Wider MWD grades are better suited for extrusion due to their higher manufacturing rates, lower die pressures and reduced melt breakage. 2.: The characteristic indicators of the grade, such as melt strength, ES-CR and toughness, are similar to those used for sheet and thermoforming applications, so similar grades are acceptable.
1. Stress cracking occurs on the outside or inside of the plastic part due to the permanent or repeated application of stress lower than the mechanical properties of the plastic; The scene of complete splitting due to the stable load result of a certain time at a specific temperature is called stress splitting; Cracks and splitting caused by overexposure to higher temperatures in some thermoplastic installments are known as thermal stress cracking. Therefore, in terms of temperature, it needs to be mastered.
2. Due to the improper activity of the melt in the mold cavity, the plastic parts table produces the shortcomings of the turbulent waveform of annual rings, spirals or clouds. Cracks in the open space on the surface of plastic processing parts and resulting damage. If the processed product is damaged, the product cannot be used normally.
