How can we facilitate the demoulding of articles from our moulds?

The problem of moulded articles not detaching from moulds is a common concern among customers.

While chrome-plating has been effective in addressing this issue, it also results in a smooth and glossy surface.

Consequently, with some part geometries, a suction cup effect is created between the mould’s surface and the moulded pieces.

The solution?

Combining chrome-plating with a satin finish. In fact, in most cases, satin finishing makes detaching moulded pieces easier.

This treatment is essential on moulds to be used with silicon, Viton, peroxide-cured rubber, and all sticky compounds, as it eliminates the “suction cup” effect, enhancing the detachment of rubber.

Chrome-plating remains the most widely used treatment for rubber part moulds. Its aesthetic and functional characteristics offer several benefits, including:

1. Customizable surface: Chrome plating allows you to obtain a shiny or matt surface depending on your needs and the type of compound used.
2. High mechanical performance: High resistance to abrasion, corrosion and oxidation, helping to extend the life of the rubber seal mould up to three times.
3. Ease of removal of the piece: Chrome plating simplifies the detachment of the piece, improving the efficiency of the production process and reducing waste.
4. Easier maintenance: Cleaning and maintenance of the mould becomes easier, as chrome plating reduces the accumulation of residues, helping to keep the surface intact and cleaner.
