Dear friends hello, welcome to read the related content of TPE materials published by Huimin Zhang. As an influential TPE material producer in south China, we will share more knowledge about TPE / TPR materials Let you know TPE / TPR materials more quickly, quickly find the right TPE materials for your products, today is December 25,2017, Christmas, first of all here to wish you a merry Christmas Well, what we are describing here today is TPE dual-material injection molding, secondary injection molding TPE material performance requirements, follow my steps together we look at... consumer products of ever-changing styles, both beautiful appearance, exquisite design, and respond quickly to market demands. Designers usually use different materials in different parts of consumer products for different purposes to meet the needs of specific environment, to extend the product life, increase beauty and practicality. This practical design requirements will undoubtedly lead to the production technology is also complicated, dual-material injection molding process is born in this trend. General dual-material products can be produced using a single-color injection molding machine, basically an injection molding machine can be competent, but the post-processing procedures are quite time-consuming and complex, directly affect the quality of products, the total cost of production is not economic. In addition to making corresponding changes to the injection molding machine, the skill of mold design is the soul of the whole technology. The mould is rotated and shifted to achieve the effect of simultaneous injection of different materials. TWO-COLOR INJECTION MOLDING TPE MOLD design can be divided into two categories: the first category has two cavity, the use of rotation mode to transfer the semi-formed mold 180 degrees to another cavity, the advantage is that the first and second processes can be synchronized; The other is a single cavity, semi-finished products together with the mold rotation 180 degrees. The design is relatively simple, but the production efficiency is reduced accordingly. As the mold or semi-finished products need to rotate, so mold design and injection molding machine requirements are more precise. In addition, due to the high variability of dual-material injection molding, in order to achieve smooth production and meet the expectations, all mold design must be considered simultaneously with product design, and the popular dual-material injection molding machine specifications are not uniform This leads to more issues to be considered in mold design; coupled with less versatility, mold manufacturers must pay more attention. Dual-material products generally ABS, PC and other hard plastic with TPE soft plastic-based, suitable for the manufacture of tableware, tool handles, watch case, telephone case and buttons and other products. This makes the production enterprise in the technical must pay attention to three points: two kinds of material fusion, product complexity and injection molding machine adjustment. For example, due to cost or application, the materials used may not have good adhesion, and dual-material injection usually requires more debugging in this regard. Our country is gradually becoming the manufacturing base of global consumer products. In recent years, manufacturers of plastic products in south China have taken on many orders that require the skill of dual-material injection The dual-material injection molding technology has been widely used in China. TWO-COLOR INJECTION MOLDING TPE TWO-COLOR MOLD STRUCTURE MOLDING FEATURES: 1, A, B two sets of mold cavity structure is the same, but after the mold is different; 2. There are two-layer ejector plates and a stepped-type ejector plate, as for the part a, the ejector plate is only the front plate (the nozzle, but the back plate (the product) is not moved until the part B is formed after the part B is formed after the part a is rotated 180 degrees; 3. To change the concept of the monochrome mold cavity of the part a, the plastic mold cavity of the part a is shaped as monochrome, then the part B is produced; 4. To combine the parts A and B, the process between them will be affected by each other. See the above TPE material processing common problem point is not helpful to you! If you don't have any of the above problems, please feel free to call us at any time. We will talk to you one by one! As TPE / TPR raw materials sales specialist, I am very like TPE / TPR materials, in this industry after all a few years is also a feeling, paid hard work and sweat! If you are developing TPE-TPR materials related products, need to understand TPE-TPR materials, need to provide technical support, then we will be your best choice, contact telephone number: 13827209711
