Point at a number or a part of the drawing.
One of four steel bars that join the stationary and rear platens. The moving platen slides along them, and they stretch slightly as they carry the clamping force.
Part of the mold height adjustment behind the rear platen. Turning the adjusting nuts moves the rear platen along the tie bars to suit the mold thickness.
Bronze sleeve lining a platen bore, so the platen slides on the tie bar without wearing the bar or the bore.
Flanged bushing in each bore of the moving platen. It guides the platen along the tie bar and keeps it square as the mold opens and closes.
Threaded nut on the tie bar end that holds the bar in the stationary platen and takes the clamping load.
Covers the tie bar end and locks the nut, so the tie bar stays in place in the stationary platen.
Tie bar liner bushing for injection molding machine platen tie bar bores.
Tie bar adjustment bushing for injection molding machine clamping force adjustment.
Tie bar end cap and lock ring for injection molding machine clamping unit.
How each part works, how it wears and what to send for a replacement quote, with drawings.
Tie bars hold your mold shut under hundreds of tons of force. When they fail, production stops completely. Here's how to inspect, maintain, and replace them before that happens.
