High-temperature tapes are masking tapes that are specially designed for use in high-temperature environments. They can withstand temperatures of up to 260°C, making them ideal for use during electroplating, which involves heating the metal substrate to a high temperature.

These tapes are available in different sizes and shapes and are ideal for masking off areas that do not require electroplating. They are easy to apply and remove and do not leave any residue or damage to the surface of the metal.

Masking Caps and Plugs:

Masking caps and plugs are used to cover specific areas of a metal surface, such as threaded holes or studs, that need to be protected from electroplating. They are available in different sizes and shapes, making them ideal for masking off irregular shapes.

Masking caps and plugs are made from materials that can withstand the chemicals and high temperatures involved in electroplating. They are easy to apply and remove and do not leave any residue or damage to the surface of the metal.

Conductive Masks:

Conductive masks are used to mask specific areas of the metal surface that require a different electroplating process than the rest of the surface. They are made from a conductive material, usually graphite, and are applied to the surface using an adhesive.

Conductive masks allow for precise masking of complex shapes and are ideal for use in electroplating processes that require different types of electroplating in different areas of the metal surface.

Masking products used during anodising

Anodizing is an electrochemical process that is used to create a protective oxide layer on the surface of a metal. The process involves immersing the metal in an electrolytic solution and passing an electric current through it to stimulate the growth of the oxide layer. Anodizing can enhance the durability and appearance of the metal surface, but it also requires precise masking to ensure that only the intended areas are anodized. In this section, we will discuss the different types of masking products used during anodizing.

  1. Anodizing Tapes:

Anodizing tapes are specially designed masking tapes that can withstand the harsh chemicals and high temperatures involved in anodizing. They are resistant to the acidic and caustic solutions used during the process, ensuring that they do not dissolve or break down during anodizing.

These tapes are available in different widths and lengths, making them ideal for masking large or small areas. They are easy to apply and remove and do not leave any residue or damage to the surface of the metal.

  1. High-Temperature Tapes:

High-temperature tapes are masking tapes that are specially designed for use in high-temperature environments. They can withstand temperatures of up to 260°C, making them ideal for use during anodizing, which involves heating the metal substrate to a high temperature.

These tapes are available in different sizes and shapes and are ideal for masking off areas that do not require anodizing. They are easy to apply and remove and do not leave any residue or damage to the surface of the metal.

  1. Masking Dots:

Masking dots are small, adhesive-backed dots that are used to mask specific areas of a metal surface that require protection during anodizing. They are available in different sizes and shapes, making them ideal for masking off irregular shapes.

Masking dots are made from materials that can withstand the chemicals and high temperatures involved in anodizing. They are easy to apply and remove and do not leave any residue or damage to the surface of the metal.

  1. Liquid Masking:

Liquid masking is a masking technique that involves applying a liquid masking material to the metal surface using a brush, spray, or roller. The liquid masking material is typically a latex-based compound that dries to form a protective film.

Liquid masking is ideal for masking irregular shapes and can be used in conjunction with other masking techniques such as anodizing tapes and masking dots. The liquid masking material is easy to apply and remove and does not leave any residue or damage to the surface of the metal.
