Design of Revolute Joints for In-Mold Assembly Using Insert Molding.
Creating highly articulated miniature structures requires assembling a large number of small parts. This is a very challenging task and increases cost of mechanical assemblies. Insert molding presents the possibility of creating a highly articulated structure in a single molding step. This can be accomplished by placing multiple metallic bearings in the mold and injecting plastic on top of them...
متن کاملDevelopment of In-Mold Assembly Process for Realizing Mesoscale Revolute Joints
In-mold Assembly process at the mesoscale presents several manufacturing challenges. Results reported in this paper demonstrate the technical feasibility of creating rigid body mesoscale revolute joints using In-Mold Assembly process. The following new results are reported in this paper. First, we describe a mold design with varying cavity shape to perform In-Mold Assembly. This mold design use...
متن کاملCharacterization and Control of Pin Diameter during In-Mold Assembly of Mesoscale Revolute Joints
Macro-scale revolute joints can be formed by first molding the hole and then molding the pin inside the hole. As the pin shrinks during the solidification process, it moves away from the hole and provides the clearance for the joint to function. The value of clearance in the macroscale joint can be controlled by carefully selecting the process parameters and the material for the pin. However, i...
متن کاملAssembly Process
Revolute joints are frequently used in articulated structures. Traditionally, such a joint is formed by assembling two components. As an alternative, revolute joints can be created inside the mold using an in-mold assembly process. This process eliminates the need for post-molding assembly, thus significantly reducing the cycle time and part count. The functional performance of a revolute joint...
متن کاملS . K . Gupta and H . A . Bruck
In-mold assembly process has been used for manufacturing articulated structures at the macro scale. But the in-mold assembly process at the mesoscale behaves differently and poses new challenges due to reduced structural rigidity of the mesoscale premolded component. One of the major challenges that need to be addressed is that of the plastic deformation of the premolded component during the se...
