The BTS 312-1191 Shot Sleeve, 145 mm × 70 mm × 30 mm, is a precision die‑casting sleeve designed for use in aluminum injection systems. Shot sleeves are cylindrical chambers in die casting machines that hold and guide molten metal until injection, a critical element of the process that affects plunger motion, seal integrity, and thermal behavior. They are typically manufactured from hardened steel (with common materials such as H-13 cited in industry references) to withstand the high temperatures and pressures of metal casting, and are intended for industrial use where exact dimensions and machine compatibility are essential.
