\nFrequently Asked Questions<\/h2>\nWhat is the MOQ for dental stone?<\/h3>\nFor 1kg bags: MOQ is 1,005 bags (approximately one carton pallet). For 25kg bags: MOQ is 40 bags (1,000kg). Contact us via Quick Quote with your required type, color, and quantity for a precise quotation.<\/p>\n Which type should I order \u2014 Type III or Type IV?<\/h3>\nType III Hard dental stone is suitable for the majority of dental lab applications including dentures, study models, inlays, and onlays. Type IV Super Hard is required for high-stress applications such as implant abutment casts and precision fixed restorations where maximum surface hardness and minimal expansion are critical.<\/p>\n Can I order multiple colors in one shipment?<\/h3>\nYes. Mixed-color orders are accepted for both 1kg and 25kg packs. Specify your required colors and quantities in the Quick Quote form.<\/p>\n Can dental stone be used for life casting and hand molds?<\/h3>\nYes. White dental stone is suitable for 3D life casting (hand, foot, body molds) using a higher water-to-powder ratio of 40ml per 100g. It produces smooth, detailed casts suitable for artistic and keepsake applications.<\/p>\n What packaging options are available?<\/h3>\nStandard bag (1kg), foil bag (1kg for better moisture protection), and kraft paper bag (25kg for bulk procurement). Custom bag sizes, colors, and OEM label printing are available \u2014 contact us for specifications.<\/p>\n What is the shelf life of dental stone?<\/h3>\n2 years from manufacture date under recommended storage conditions \u2014 cool, dry place, away from moisture. Keep bags sealed until use.<\/p>\n Do you supply dental stone for orthopedic casting?<\/h3>\nYes. White dental stone is used in orthopedic casting applications. Compressive strength is slightly lower than dental-grade Type III \u2014 contact us for specific orthopedic casting specifications and pricing.<\/p>\n
