What Is Vacuum Casting?
Vacuum casting is a precision polyurethane replication process that bridges the gap between rapid prototyping and industrial injection molding. A master model is created via CNC machining or SLA 3D printing, then suspended in a mold box and embedded in liquid silicone to form a flexible negative mold under vacuum. Polyurethane resin is then poured into the cavity under complete negative pressure, eliminating micro-voids and replicating every surface detail of the original master with production-grade accuracy.

Preguntas frecuentes
Q1: Can we sign a legally binding corporate NDA before uploading proprietary CAD files?
A1: Absolutely. Information protection is our highest priority. We routinely review and sign Non-Disclosure Agreements (NDAs) to legally seal your files before any transmission occurs.
Q2: What is your strict Minimum Order Quantity (MOQ) for a casting run?
A2: Profit Machining scales dynamically with your development needs. We enforce no minimum batch thresholds; we happily accept 1-piece master verification mockups up to mid-volume production runs.
Q3: How many casting shots can you yield from a single silicone tool cavity?
A3: Depending on part geometry and resin aggressiveness, our industrial-grade silicone yields 20 to 25 high-fidelity parts before tool deterioration begins. We build duplicate molds if your order volume exceeds this threshold.
Q4: How do you compensate for polymer volumetric shrinkage during curing?
A4: Our specialized CAM software calculates the volumetric contraction coefficient of the specific polyurethane resin beforehand, up-scaling the master model coordinates to offset shrinkage exactly.
Q5: Can vacuum cast parts replicate fine surface textures like knurling or micro-grooves?
A5: Yes. Our silicone molds replicate micro-textures, knurling patterns, and sharp internal radii down to 0.05mm resolution with exceptional fidelity.
Q6: What is your typical lead time for a production-ready vacuum cast part?
A6: Master verification can be completed within 3-5 business days. Low-volume production runs of 20-100 units are typically delivered within 7-14 working days from drawing clearance.
