Tips For Feed System Design of Injection Mold

Injection mold design is an important part of plastic product development. As a mold maker and injection molding factory,  in order to improve the quality of parts, enhance tools performance and  save manufacturing cost, we always keep thinking how to optimize the  design and fabricating level of the molds.


During  design process, it is necessary to make a choice for the gate position  and quantity, so as to control the material filling process.  CAE  analysis is able to provide several advices for designer to decide the  gate location, and give relevant comments according it’s influence.  Optimizing the gate position is essentially make verify the proper gate  position and technological parameter to produce best plastic part.


Take  the injection molding systems as example, designer should divide the  feeding system into several steps, then complete and optimize the whole  system design step by step:


1)  Initial  confirmation of the design proposal. With the help from software design  tool, designer does synthetic judgments and calculation to the  reference information, based information and regularities, to confirm  the hydraulic fluid distribution of feed system, determine the gate type  which can raise the feeding speed, gate location and quantity in  detail.


2)  In  the modifying and adjusting process, designer needs to adjust the route  of fluid go through and reduce the area of path to raise the feeding  speed of material according to manufacturing requirement and design  purpose. Optimize components precision as per the gate quantity, design  the exterior of the mold as per the gate type like direct gate,  rectangle gate, pin-point gate, tunnel gate, etc.



3)  Collect/summarize  the data/information above and input to the design model, inspected by  the feeding system, check if there’s any error for the gate design. If a  balanced filling mode can be promised by the design of gate location,  then it will make the pressure, temperature and the distribution of  shrinkage even, so the part quality will be better. Therefore, the  choice of gate position is usually be determined by flow balance or not.  


The  key issue of injection mold design work is feed system design the  cooling classify system design, we will talk about the latter in the  future.
