2.High Precision & Low Shrinkage: Shrinkage rate ≤0.2%, ensuring high-precision replication of hobby craft details, perfectly restoring delicate lines, tiny patterns and subtle textures, suitable for making molds of small, delicate and complex hobby crafts.
3.Excellent Fluidity & Easy Operation: Low viscosity and excellent fluidity, easily flowing into tiny gaps of hobby prototypes, no professional skills required; simple mixing ratio, easy to operate, supporting three mold making methods, ideal for hobbyists and small manufacturers.
4.Easy Demolding & No Residue: Smooth surface after curing, good release performance, easy to demold without damaging hobby prototypes or leaving residues, ensuring the integrity and aesthetics of the replicated crafts, reducing post-processing workload.
5.Versatility & Cost-Effectiveness: Suitable for various hobby casting scenarios, including toys, craft gifts, POLI crafts, resin crafts, candles and lighting accessories; cost-effective, perfect for small-batch production and hobby creation, compatible with Rapid prototyping silicone for quick mold making. How to Use (3 Mold Making Methods)
1. Cladding Mold Method
- Prepare the hobby prototype, clean it thoroughly and dry it to ensure no dust or moisture affects mold adhesion and durability.
- Mix the silicone (Component A) and curing agent (Component B) at a weight ratio of 100:2, stir slowly and evenly to avoid generating air bubbles, which will affect the mold’s precision and service life.
- Enclose the hobby prototype with a mold frame, pour the mixed silicone into the frame, and place it in a vacuum machine for degassing to eliminate air bubbles completely.
- Let the silicone cure naturally at room temperature; after full curing, demold carefully to obtain a durable, high-precision hobby casting mold.
2. Brushing Mold Method
Brush the evenly mixed silicone onto the surface of the hobby prototype in 2-3 layers, each layer dried before brushing the next to ensure uniform thickness and durability; after full curing, add a supporting frame to enhance mold stability, then demold for use.
3. Casting Mold Method
Pour the mixed and degassed silicone directly into the mold frame containing the hobby prototype, ensure the prototype is fully covered; after natural curing, demold easily, and the mold is ready for hobby casting replication.
Application Scenarios
This specialized durable mold making silicone is widely used in hobby casting and small-batch craft mold manufacturing, including toys, craft gifts, POLI crafts, resin crafts, candles, lighting accessories, decorative figurines and products with delicate or complex patterns. It is perfect for hobbyists, small manufacturers and small-batch procurement, helping to improve hobby casting efficiency, ensure product consistency, reduce mold making costs, and enhance product competitiveness in the global hobby craft market.
