Kritika Die Mould Accessories Co is the Customizable Sleeve Ejector Pins Manufacturers in Pune. We manufacture precision-grade Sleeve Ejector Pins, also called two-stage ejectors or ejector sleeves, and are a necessary tool in complicated moulding operations. Unlike traditional ejector pins using a point-of-contact thrust against the part, a round or stepped geometry moulded part ejection is done by a tubular sleeve using sleeve ejector pins. The pins are typically wound around a centre pin or core and are used when a standard pin would mar or mark the part. Our sleeve ejectors are commonly used on moulds in delicate-looking pieces like pipe fitting, bottle cap, threaded part, or hollow cylinder-shaped parts needing to be clean, evenly ejected from a mould cavity. We stock a vast range of sleeve ejector pins such as standard cylindrical, stepped sleeves, vent sleeves to facilitate gas out and lubrication groove sleeve pins for long-life applications. An available range of diameters is from 3 mm up to 30 mm and lengths from 50 mm up to and in excess of 250 mm with custom sleeve ID and wall thickness options available.
We can get you the most Advanced Sleeve Ejector Pins in India. Whether a moulding tool is required for thin-walled plastic products, high-cavity moulds, or continuous moulding machines, our configurations reduce wear and increase efficiency of ejection. We offer total sets with matching centre ejector pins and options of retainers on integral tool mould arrangements. We maintain fine tolerances on centre of concentricity, roundness, and straightness along the length of each sleeve ejector pin. Our outer and inner diameters are precision-ground so as to have minimum play on the sleeve and it remains in form even when high-speed ejection takes place. The coaxial alignment of sleeve and guide pin is of paramount importance and we observe international standards like DIN, JIS, and IS fitment tolerances. We design our sleeve pins such a way so as to avoid any flashing or rubbing mark on the finished product produced, especially in tooling arrangements wherein cosmetic finishes are a requirement. Special tolerance and variation by length are available on mould cavity size, stroke requirement, and operational length of stroke.
