Its structured bottom profile ensures stable alignment within mould systems while maintaining effective heat retention for directional solidification. By delaying solidification in the riser zone, it reduces shrinkage defects, improves casting soundness, and increases metal yield. \u003c\/p\u003e\n\u003cp\u003eThe sleeve supports efficient feeding performance and minimizes riser size, helping foundries optimize productivity and reduce metal loss.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":42476455428194,"sku":null,"price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/5058\/8770\/files\/7_cd59f860-484e-4d7d-85e2-865b9e3cc7e4.png?v=1773934050","url":"https:\/\/www.specialmineral.com\/products\/square-bottom-insulating-sleeves","provider":"My Store","version":"1.0","type":"link"}
