Plastic processing / molding Resin molding Original plastic molding method IMP method / IMM method Our proprietary plastic wall thickness high-precision molding technology "IMM method" eliminates the lack of strength from the ground up and realizes highly reliable plastic parts and resin parts. Realized the strength modification of the weld line that had been given up by the "IMM method" The "IMM method" is a processing method developed for the purpose of promoting the resinification of metal parts. Insufficient weld line strength is a major issue in the industry, and this method is particularly effective in modifying weld line strength in glass fiber and carbon fiber reinforced resins. (IMM method: Abbreviation for in-mold moving method) (The IMM method is a processing method originally developed by our company.) ↑ This is a strength test product with gates placed at both ends of the product and a weld line formed in the center of the product. In normal molding, the fracture is linear from the weld line formed in the center of the product, but in the IMM method, the fracture site is moved from the center of the product, and it is observed that the fracture surface is jagged. ↑ The results of tensile / bending strength comparison are shown by this test sample. In both tests, it can be confirmed that the IMM method improves the strength with weld by 60%. In addition, it is possible to achieve strength that is comparable to that without welds (1-point gate). You can see the tensile test / bending test video ↑ This is an image of observing the fiber orientation of this test sample. In normal molding, the fiber orientation of the weld line is lined up vertically, but in the IMM method, the vertical fiber orientation cannot be observed at the same position. What kind of processing method is the IMM method? The IMM method is the only technology that solves the insufficient strength of weld lines that occurs in plastic materials containing fibrous additives (glass fiber and carbon fiber). By intentionally changing the internal flow of the resin during injection and breaking the weld line, the fiber orientation is changed and the strength of the weld line is modified. At the same time, the product can be compressed (IMP method), so both voids and weld lines can be improved. It is possible to deal with it by modifying the existing mold. (Please contact us for details) What you can do with the IMM method Controls the flow of molten resin in the cavity, which is not possible with normal injection molding 1. Suppress the lack of strength of the weld line 2. Suppress the swelling of the weld line 3. Suppresses appearance defects in the weld line Product shape that can be used by the IMM method The IMM method can use the structure of a normal injection molding die, and there is a degree of freedom in the product shape that can be handled. 1. Undercut product with slide piece structure 2. Products with holes 3, taking a large number of pieces, etc. ⇒For details, proceed to "Product Design". VA / VE proposal effect point Resinization of metal parts Improved strength reliability by solving the weld line strength problem. Weight saving No need to take measures to increase the cross-sectional area by improving the weld line strength Composite parts By improving reliability for complex shapes, mold production costs are reduced and the number of parts is reduced. Improvement of appearance parts 1 Relaxation of appearance lines by relaxing the orientation of the weld line Improvement of appearance parts 2 Relief of swelling of the oriented part by relaxing the orientation of the weld line part Removal of metal inserts Simplification of molding and improvement of recyclability by solving the weld line problem around the insert Feel free to contact us for inquiries, consultations, quotations, etc. regarding plastic molding and processing.
