Many customers looking for custom molding manufacturers, the first thing is to quote, in fact, not, custom molding price is related to all aspects of injection molded products, custom molding offer before the need for injection molded parts for the “six elements” of the analysis.
1) Feasibility analysis of injection molded products and structure
The structural elements of the injection molded product determine the mold opening accuracy, the number of cavities, and mold life.
When analyzing the structure of the injection molded product, it is necessary to combine the functional requirements of the product, as well as 2D drawing tolerance requirements, appearance requirements, injection molding machine requirements, as well as the characteristics of the molding material, and when customizing the mold, it is necessary to comprehensively consider the product to meet the functional and dimensional requirements. In addition to custom molding need to put shrinkage, in the area of possible deformation, or shrinkage of the region, the mold needs to do compensation calculations, as far as possible to do the pre-steel position of the intention to reserve.
(2) injection molded products on the hole slot and thread analysis
First of all need to understand the product holes and threads of the assembly requirements, 2D size tolerance requirements, and torque requirements, whether in the front mold or rear mold part, the mold will be used in inserts to process, to ensure that the processing accuracy and maintenance of the later convenient.
3）Deformation and misalignment analysis of injection molded products
Especially for thin-walled, narrow, thin and long, precision injection molded parts and other types of products and products with a lot of packing force, before the design needs to be taken into account in the molding of products prone to warping, bending and other defects, so it is necessary to do a good job in advance to improve the program.
(4) injection molded parts product mold design is completed after the overall motion interference analysis
In particular, the structure of injection molded products need to use the slider and tilting top of the case, it must be combined with the ejector mechanism to carry out motion interference analysis.
5）Appearance defect analysis of plastic parts
Sometimes after the T0 test mold, the product will cause the surface to produce flow marks, shrink marks, underfill, silver grain, obvious bonding lines, trapped air and other phenomena. Therefore, it is necessary to carry out mold flow analysis before custom molding to find out these problems in advance and improve them.
6) Batch demand analysis of injection molded products
The batch demand analysis of injection molded products needs to take into account the three elements of molding: temperature, pressure, time, and the impact of the service life of the injection mold.
