12oz Cone Mug Vacuum Clamp: Silicone Press Accessory for 3D Oven Press Sublimation

Achieve consistent sublimation results on cone-shaped mugs with our 12oz cone mug silicone vacuum clamp 3D oven press accessory. This silicone clamp is designed specifically for 12oz cone mugs. It wraps around the mug and holds the sublimation transfer firmly against the surface during the 3D oven press cycle. Because the clamp is silicone, it conforms to the tapered cone shape and applies even pressure across the entire curved surface. That consistent pressure is what produces a fully bonded, ghost-free sublimation print from rim to base. Sold individually.

Why Cone Mugs Require a Dedicated Clamp and Cannot Be Pressed Without One

A standard cylindrical mug has a uniform diameter from top to bottom. A cone mug tapers from a wider rim to a narrower base. That taper means a standard mug wrap or generic silicone sleeve cannot conform to the shape correctly — pressure will be uneven, and the transfer will shift or partially bond during the press cycle. An uneven press on a cone mug produces blurred edges, incomplete colour transfer, and ghost lines where the paper moved under inconsistent pressure.

The 12oz cone mug vacuum clamp solves this problem because it is shaped to match the taper of the 12oz cone mug exactly. When you place the clamp over the wrapped mug and load it into the 3D oven press, the silicone contracts under heat and applies even pressure across the full tapered surface. Because silicone is flexible, it accommodates the cone geometry without gaps or pressure points. The result is a clean, edge-to-edge sublimation print that a flat press or unsupported oven press cannot reliably produce on a cone-shaped surface.

How to Use the 12oz Cone Mug Vacuum Clamp

Print and trim your sublimation transfer to fit the 12oz cone mug. Wrap the transfer around the mug and secure it with sublimation tape. Slide the silicone vacuum clamp over the wrapped mug until it sits evenly from rim to base. Place the assembled mug and clamp into the 3D oven press and press at the recommended temperature and time for ceramic mugs — 200°C for 240 seconds. Remove carefully after the cycle and peel the transfer while warm for best results.
