Designed for Different Applications
01
Resin Casting Molds
For jewelry, decorative parts, craft molds, and detailed resin casting.
Fine detail reproduction, smooth surface finish and easier demolding.
02
Concrete & Stone Molds
For decorative concrete, textured stone molds, wall panels and architectural casting.
Better durability, stronger tear resistance and more repeatable use.
03
GRC/GFRC/Architectural Molds
For decorative panels, textured surfaces and larger mold structures.
Practical durability, good detail transfer and stable mold performance.
04
PU & Industrial Prototyping
For prototype parts, product development and functional casting molds.
Stable curing, reliable molding performance and better size consistency.
How to Choose The Right Mold Making Silicone？
The right grade depends on your casting material, mold size, required detail and demolding stress.
| Application | Recommended Shore A | Key Features |
|---|---|---|
| Soft & Flexible Molds (Best for candle, soap, delicate designs) | 10–20 | Easy release, very flexible |
| General Purpose Molds (For resin, crafts, and standard applications) | 20–30 | Balanced strength and flexibility |
| Heavy-Duty Molds (For concrete, PU, and industrial casting) | 30–40 | Higher durability, longer lifespan |
WHAT SETS US APART
Better Mold Performance and More Reliable Supply
Low Shrinkage for Better Accuracy
Helps maintain mold dimensions and detail consistency during casting.
High Tear Strength for Longer Mold Life
Better suited for repeated demolding and more demanding mold structures.
Stable Curing for More Predictable Production
Designed for more consistent processing and more reliable batch-to-batch performance.
Supply Stability and Technical Support
From sample evaluation to bulk supply, we support application-based grade recommendation and technical document sharing for suitable projects.
For projects with specific market or application requirements, selected grades can be discussed together with available technical documentation.
Used in Real Mold Making Projects
Resin Mold Applications
Suitable for molds that require fine pattern reproduction and cleaner surface detail.
Concrete Mold Applications
Used in repeat casting projects where durability and release performance are important.
Prototype Mold Applications
Supports projects where stable molding and dimensional consistency matter.
You ask, we answer
Questions Buyers Usually Ask Before Ordering
Lower Shore A grades are softer and easier to release. Higher Shore A grades are usually preferred for molds that need better durability and longer service life.
Platinum cure silicone is often chosen for lower shrinkage, better dimensional stability and cleaner molding performance. Tin cure may still suit some general-purpose projects depending on cost and application.
