Silicone Mug Vacuum Clamp, 11oz Universal Fit for Ghost-Free Sublimation Pressing

This silicone mug vacuum clamp is a flexible silicone pressing tool designed to hold a standard 11oz mug securely inside a vacuum mug press during sublimation, ensuring consistent, even pressure across the full curved mug surface throughout the heat cycle. The flexible silicone construction conforms to the body of a standard 11oz mug, maintaining a secure and even grip that prevents the mug from shifting, rotating, or lifting during pressing. Because the clamp holds the mug and transfer paper firmly in position throughout the full heat cycle, it eliminates the movement that causes ghosting, blurred edges, and incomplete colour transfer on finished mugs. Universal fit for most standard 11oz mugs. Sold individually. Browse our full product catalogue to explore our complete sublimation tools and accessories range.

Why a Silicone Vacuum Clamp Is Essential for Consistent Ghost-Free Mug Results

Ghosting on ceramic mugs is one of the most common and frustrating quality failures in sublimation production. It occurs when the transfer paper shifts even fractionally during the heat cycle, creating a blurred double-image effect that ruins the finished mug and wastes both the blank and the transfer. The silicone mug vacuum clamp eliminates this problem by securing the mug and transfer paper in a fixed, immovable position inside the vacuum press from the moment the cycle begins to the moment it ends. Moreover, the flexible silicone material conforms to the curved surface of the mug body rather than gripping it rigidly, distributing pressure evenly across the full surface and preventing the uneven contact points that cause partial transfer and colour inconsistency. Because the clamp is universal and fits most standard 11oz mugs, it integrates immediately into any existing 11oz vacuum press setup without additional modification. Additionally, silicone is heat-resistant and durable, maintaining its shape and grip performance across thousands of pressing cycles. Therefore, this clamp is an essential tool for any sublimation operator producing 11oz ceramic mugs to a professional standard.

Compatible Equipment and Usage

This silicone mug vacuum clamp is compatible with vacuum mug presses designed for standard 11oz mugs. It is suitable for use with most vacuum mug press models that accept 11oz cylindrical mugs. Always check that your vacuum press model is designed for 11oz mugs before use. To use, position your sublimation transfer paper around the 11oz mug with the printed side facing the mug surface. Place the wrapped mug into the silicone clamp and insert the assembly into your vacuum mug press. Run your press at the standard sublimation temperature and time for ceramic mugs, 200°C for 240 seconds. Allow the mug to cool fully before removing the clamp and transfer paper.
