For jewellers, using impression dies and shot plates can add intricate designs and professional textures to your pieces. Whether you’re a seasoned artisan or a hobbyist, mastering these tools is a game-changer. In this guide, we’ll walk you through the essential steps, tools, and safety tips for working with impression dies, ensuring you achieve the best results every time.
What Are Impression Dies and How Do They Work?
Impression dies are tools that help you press detailed designs into metal, creating custom patterns and shapes. Combined with a hydraulic press, they allow you to quickly and accurately add texture and dimension to your work. With a little practice, you can create your impression using a simple hammer too. Unlike traditional stamping, impression dies work by forming metal into a shape, rather than cutting through it, making them ideal for detailed designs.
Shot plates are very similar but more often refer to the smaller design options. The design is often formed on a lump of silver (such as some scrap soldered into a ball) rather than sheet metal or wires. These dies are perfect for adding a distinct style to your jewellery.

How do I prepare my metal to use with the shot plate?
There are two ways:
- Use a blowtorch to melt the metal into a ball, pickle it, then place in the die
- Use a blank (piece of sheet metal) twice the depth of the impression, and anneal
For wire dies, flatten your wire with a soft mallet, then simply lay onto the design.
How do I get the impression onto my metal?
Lay your blank, wire or ball of metal over the design. There are two ways to get the impression:
- Hammer & Punch Method: direct the punch into the die and use a flat headed hammer to strike the punch hard. Always work on a stable surface.
- Hydraulic Press Method: Use your press as instructed.
How do I remove my metal from the die?
Try to use slightly more metal than you think you will need to allow you to lift the metal out. A knife can be carefully inserted underneath the edge of the metal to help. Keep the shot plate oiled before using as this will make the metal much easier to remove.
What can I make using the impression dies?
Shot plates and impression dies can help you create beautiful decorative jewellery. They are ideal for earrings, lockets, pendants, brooches and more. You can use a piercing saw to cut around the design, then file the edges to a smooth, flat finish. These cut pieces can even be soldered onto larger designs - just take care not to melt your creation!
There’s no universal guide for how much pressure to apply or what gauge of metal to use for each die. Experimentation is key. Keep notes on what works best for each design so you can replicate your results in the future. It's always a good idea to practice on some scrap metal or copper before going ahead with your more costly metals.
