]]> Comment on How much does a mold cost? by Elito http://imoldmaking.com/injection-molding/how-much-does-a-mold-cost/comment-page-1/#comment-66 Elito Thu, 15 Jul 2010 10:13:40 +0000 http://imoldmaking.com/?p=32#comment-66 It really depends on a lot of factors as mentioned on the post. The easiest way is to identify the number of hours that you are going use to produce each and every mold part then multiply that by your shop's processing cost per hour. Plus materials, standard components, and mold base costs which you will eventually purchase from specialized vendors. More dimensions mean more checkpoints so you have to consider modifying some mold parts if the measurement fails. It really depends on a lot of factors as mentioned on the post.

The ram type is like hydraulic clamping where the mechanism involves a piston, a cylinder, and a fluid pumping into it. On the other hand, the toggle type is a clamping mechanism in which linkage, motors and screws can be used as shown in the image <a href="http://www.freepatentsonline.com/6811394-0-large.jpg" rel="nofollow">shown here</a>. The ram type injection machine can have a very high tonnage depending on its piston diameter. But it is less energy efficient than the toggle type because the fluid continues to be pumped throughout the injection cycle. The toggle type injection machine is only up to 2000 tons (I think) mainly due to the power capacity of the motor or the strength of its linkage. The linkage is only as strong as its weakest link. It is energy efficient because it consumes power only when the motor rotates. The difference is on their clamping mechanism.
