{"product_id":"new-sand-casting-flask-cast-iron-4-pins","title":"New Sand Casting Flask","description":"\u003cp\u003eThis sand casting flask is imported from India and constructed of cast iron, offering a sturdy, reliable frame for sand casting applications. Slightly larger than the classic sand casting flask model, it features a usable internal size of 4-3\/8\" high by 2-7\/8\" wide by 2-1\/4\" deep, making it well-suited for casting projects that require a bit more working room. The external dimensions measure 4-15\/16\" high by 3-1\/2\" wide by 2-1\/8\" deep.\u003c\/p\u003e\u003cp\u003eFour alignment pins keep the two flask halves securely registered during use. A notable design improvement over the classic model is the absence of an internal ridge at the parting line — the internal walls meet cleanly where the two sides come together, producing a smoother interior surface that supports better sand packing and cleaner mold separation.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCast iron construction for durability and rigidity\u003c\/li\u003e\n\u003cli\u003eUsable internal dimensions: 4-3\/8\" high × 2-7\/8\" wide × 2-1\/4\" deep\u003c\/li\u003e\n\u003cli\u003eExternal dimensions: 4-15\/16\" high × 3-1\/2\" wide × 2-1\/8\" deep\u003c\/li\u003e\n\u003cli\u003e4 alignment pins keep both halves precisely registered\u003c\/li\u003e\n\u003cli\u003eSmooth internal walls with no ridge at the parting line — an improvement over the classic model\u003c\/li\u003e\n\u003cli\u003eSlightly larger interior than the classic sand casting flask\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eCast iron\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInternal Dimensions\u003c\/th\u003e\n\u003ctd\u003e4-3\/8\" high × 2-7\/8\" wide × 2-1\/4\" deep\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eExternal Dimensions\u003c\/th\u003e\n\u003ctd\u003e4-15\/16\" high × 3-1\/2\" wide × 2-1\/8\" deep\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAlignment Pins\u003c\/th\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eIndia\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Grobet USA","offers":[{"title":"Default Title","offer_id":43583667929302,"sku":"122.953SC","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/new-sand-casting-flask-otto-frei.jpg?v=1719956559","url":"https:\/\/www.ottofrei.com\/products\/new-sand-casting-flask-cast-iron-4-pins","provider":"Otto Frei","version":"1.0","type":"link"}
