Factors Affecting the Price of Twin Screw Extruder Flower Shape Mould

  • Mould Material (Most Critical Factor)
    • Stainless steel grade: SUS304 (basic low cost), SUS316L (anti-corrosion, +30%~60% price), wear-resistant die steel H13/SKD61, carbide insert die for aquafeed (2–5 times higher cost).
    • Surface treatment: Common polishing, nitriding, TD coating, electropolishing for food export, extra cost for wear-resistant treatment.
    • Mould thickness & weight: Large-diameter thick dies consume more raw material, higher price.
  • Pattern & Structure Complexity
     
    Simple flower, round hole, single channel: low cost; multi-petal flower, cartoon shape, co-extrusion double-layer sandwich die, hollow 3D patterns require 5-axis CNC & EDM, processing cost rises 50%–150%. More die holes also increase polishing & inspection cost.
  • Size & Extruder Matching Specs
     
    Lab small twin screw extruder dies are cheap; industrial large D85/D90/D120 dies cost double. Custom non-standard flange for different twin screw models needs extra machining cost. High-pressure thickened dies for floating fish feed are more expensive.
  • Machining Precision & Craft Standard
     
    High tolerance ±0.02mm for European & US food factories requires 5-axis processing, extra 30% processing fee. Mirror food-grade polishing, multiple trial runs for complex patterns add trial production cost.
  • Customization Requirements
     
    Standard stock patterns have no design fee; custom ODM drawing design, flow simulation will charge design cost. Complete die assembly with splitter plate, sealing rings costs more than single die plate. FDA/CE material inspection reports generate extra testing fees.
  • Order Quantity & Lead Time
     
    Single piece retail price is highest; bulk order over 10 sets gets 10%–30% discount. Rush delivery within 3 days adds 20%–50% urgent charge. In-stock standard dies are cheaper than newly customized dies.
  • Manufacturer Brand & After-sales Service
     
    Professional factories with strict inspection & 6–12 months warranty offer higher quotation than small workshops without wear treatment. Extra service like free size matching, overseas technical support will slightly increase the price.
  • End Application Field
     
    Snack food dies work under low pressure with less abrasion, moderate price; pet feed & aquafeed dies need wear-resistant steel, higher cost. Mini lab dies with tiny holes have high unit price due to hard processing.
