As rapid-prototyping and resin-printed patterns have become standard in modern casting workflows, traditional investments often struggle to accommodate their unique expansion and thermal characteristics. Plasticast was developed to meet that demand directly.\u003c\/p\u003e\n\n\u003cp\u003eWith the wide variety of RP materials available and their correspondingly different burnout behaviors, Plasticast delivers the strength and forgiveness needed to eliminate flashing and spalling — two of the most common failure points when casting with resin patterns. It is equally compatible with standard injection wax, making it a versatile choice for shops working across multiple pattern types.\u003c\/p\u003e\n\n\u003cp\u003eLike all Ransom \u0026amp; Randolph investments, Plasticast produces a smooth casting surface with little to no surface imperfections, and it is formulated to deliver consistent results from batch to batch — critical for production environments where repeatability matters.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSpecifically formulated for plastic and resin rapid-prototype (RP) pattern materials\u003c\/li\u003e\n\u003cli\u003eOnly water-based investment proven effective with difficult RP substrates\u003c\/li\u003e\n\u003cli\u003eEliminates flashing and spalling associated with resin pattern burnout\u003c\/li\u003e\n\u003cli\u003eCompatible with standard injection wax as well as RP materials\u003c\/li\u003e\n\u003cli\u003eProduces a smooth casting surface with minimal surface imperfections\u003c\/li\u003e\n\u003cli\u003eConsistent batch-to-batch performance for reliable production results\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eRansom \u0026amp; Randolph\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInvestment Type\u003c\/th\u003e\n\u003ctd\u003eWater-based phosphate-bonded casting investment\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePrimary Application\u003c\/th\u003e\n\u003ctd\u003ePlastic and resin RP pattern materials; standard injection wax\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePackage Size\u003c\/th\u003e\n\u003ctd\u003e44 lb box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProp 65 Warning\u003c\/th\u003e\n\u003ctd\u003eContains crystalline silica — see safety information below\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSafety Warning — Crystalline Silica:\u003c\/strong\u003e This product contains a blend of crystalline silica.
