Vacuum Casting
What are your tolerance standards for silicone mold duplication? Can they achieve ±0.1mm accuracy?
Our standard tolerance for silicone mold duplication is ±0.3mm (per ASTM D2000). For ±0.1mm precision, we implement the following measures:
Low-shrinkage silicone: Materials with shrinkage rates <0.1% (e.g., Dragon Skin™ FX-Pro).
Multi-stage pressure control: Vacuum casting with gradient pressure (0.8–1.2 bar).
CNC machining allowances: Critical dimensions ±0.05mm post-casting machining margins.
What is the lifespan of silicone molds? What is the maximum output per mold?
Mold lifespan varies by material grade:
Standard silicone (e.g., Smooth-Sil 940): 20–30 parts.
High-performance silicone (e.g., Zhermack ZA 8): 50–100 parts.
Composite molds with metal reinforcement: Up to 200 parts.
Are small-batch orders (e.g., 50 units) feasible? How do you optimize costs?
Yes. We optimize costs through:
Mold reuse: Multiple batches within a total lifespan.
Multi-cavity layout optimization: 40% material utilization improvement.
No MOQ: Unit price = material cost ×1.15 (15% loss factor).
What level of surface detail replication can you achieve (e.g., textures, logos)?
Surface replication is classified per VDI 3400:
Class A: Ra ≤0.8μm (replicates 10μm-level textures).
Class B: Ra ≤1.6μm (general logos/patterns).
3D laser-engraved master molds: ±5μm accuracy.
How do you prevent bubbles and delamination in multi-material insert casting?
For metal/plastic inserts:
Pre-heating inserts: 80°C to minimize thermal stress.
Extended degassing: Vacuum ≤5mbar for 15 minutes.
Interface enhancers: e.g., Loctite 770 for silicone-insert bonding.
