Differences of Materials of Dies
There are silicone rubber dies and metal dies for hot stamping process.
There are silicone rubber dies and metal dies, the latter could be further divided into copper die and zinc die. The differences between silicone rubber dies and metal dies and the two major metal dies are described as below.
Soft Die and Hard Die
Two Major Items: Silicone Rubber and Metal (Copper / Zinc)
| Silicone Rubber Die | Metal Die | |
|---|---|---|
| Features | Silicone rubber covered on aluminum sheet. Thickness of aluminum sheet: 1 ~ 1.5 mm approx. Thickness of silicone rubber: 1 ~ 3 mm approx. | Metal die has extraordinary mechanical properties, physical properties, electrical conductivity, thermal conductivity, and erosion resistance. |
| Thermal conductivity | Slow heat conducting. Higher temperature needed for hot stamping. | Fast heat conducting. Lower temperature needed for hot stamping. |
| Benefits | Softer material, less obrious mark after stamping. | Hard material. No deformation even under high pressure stamping. Suitable for stamping very fine font. |
| Drawbacks | Deformation or thickened font size might take place after stamping. | Color deviation after stamping. Causing uneven surface on substrates. |
| Differences | Soft material suitable for curved plastic material. Wider applications. | Hard material suitable for paper or object with smooth surface. |
Summary:
Which die to use depends on what products are expected. You could also use copper die to create sunken effects on surface.
Copper Die and Zinc Die
| Copper Die | Zinc Die | |
|---|---|---|
| Thickness | High | Low |
| Durability | High | Low |
| Price | High | Low |
Summary:
Which to use: go for copper die when large quantities is needed; for small amount of production, use zinc die.
