The tie bar helps to main a fixed distance between the moving plate and the fixed plate. Whenever the toggle or RAM moves, the tie bar helps to maintain the linear motion of the flow. The gap between two tie bars is called tie-bar distance. Tie bar distance is written on the machine or its manual. For example, if it has been mentioned on a machine as the gap in length as 610mm and the gap in width as 610 mm, there is a gap of 610mmlengthwise and widthwise between the two plates. This gap is called a tie bar. Let us look at the important features of the tie bar in injection molding.
Flexibility and cost efficiency: Machines with less tie bar have high production. Thus such machines are flexible and cost-efficient. Certain applications like robotics involve less tie bar in injection molding.
Freedom for automation: in the case of automatic machines, machines are there which require automation. Thus, there are machines that are tie bar or tie bar less. In tie-bar fewer machines, the automatic system has to be kept inside the machine. Thus, time is saved. These types of devices are generally costly, to begin with initially.
Eco-drive: eco drive saves the energy consumption of the drive system as well as the cycle time. It means that the electricity bills are lower. Also, about 70 percent of energy consumption is saved.
Quick mold changes: tie bar less machine can adjust rapid changes inside the mold.
Force divider: in tie bar fewer machines, there is an equal distribution of the clamping force over the entire mold surface.
