The Role of Tie Bar And Accessories
Precision Machining
Our tie bar guide rods are precision-machined to exacting tolerances, guaranteeing a perfect fit within the tie bar bushings. This precision is essential for maintaining the alignment of the tie bars and preventing any deviation during the molding process.
Lubrication Systems
Efficient lubrication is crucial to minimize friction between the tie bar and guide rod interface. Our injection molding tie bar guide rods feature advanced lubrication systems that not only reduce wear but also contribute to smooth and consistent operation over extended periods.
Trouble-Shooting For Injection Tie Bar And Accessories Broken
In the design, it is necessary to avoid the sharp change of the shaft diameter. At the step or undercut, try to use a large round corner transition, choose a material with better comprehensive performance, and special treatment should not only solve the hardness of the thread surface (to be wear-resistant) and Try to reduce the surface stress concentration, improve the surface finish, and minimize stress damage.
It is necessary to ensure the processing accuracy, especially the length of the connecting rod, the height of the bearing seat, the accuracy of the cross head, and the positioning accuracy of the bearing seat on the template.
Pay special attention to the length of the four tie bars during assembly or after removing the mold adjustment nut, and the distance between the mold adjustment nut and the rear template must be adjusted.
Analyze the reason when the product has flash, do not increase the clamping force unilaterally, if the mold is found to be uneven, it should be smoothed, if the length of the connecting rod is uneven, it should be corrected, including copper pads, paper, etc. Nut.
