Tiebar

Tiebar is a term with several related meanings in different fields. In fashion, a tie bar (or tie clip) is a slender metal bar designed to fasten a necktie to a shirt. It is typically placed across the upper portion of the tie, near the chest, to hold the tie in place and keep it aligned with the shirt. Tie bars come in various finishes and materials, such as stainless steel, brass, or plated metals, and ranges in size to suit different tie widths.

In engineering and manufacturing, a tie bar refers to a rigid bar that connects components and resists axial loads. It is used as a structural member in frames, machinery, and tooling to transmit tensile force and maintain alignment between connected parts. Tie bars are common in assembling frames for machines, fixtures, and support structures, where they help maintain stiffness and stability under load.

In injection molding and molding machinery, tie bars are the main horizontal bars that span between the platens of the clamp unit. They form the frame of the clamping area and carry the clamping force generated by the hydraulic or mechanical system. The integrity and proper lubrication of tie bars are important for maintaining mold alignment and consistent production.

Materials and maintenance vary by use. Fashion tie bars are typically made from durable metals with finishes that resist wear and tarnish. Structural and molding tie bars are usually made from high-strength steel alloys and are designed to withstand repetitive loading, with inspections for wear, corrosion, and proper alignment as part of regular maintenance.
