Pre-Treatment Process for metals 

Amfin offers a variety of pre-treatment applications including grit blasting, abrasive blasting, and non-metallic blasting. Other pre-treatments incorporate cleaning and degreasing of materials, acid descaling of austenitic stainless steels and nickel-based alloys. 

The pre-treatment process for metals typically involves cleaning the surface of the metal to remove any debris, dust, or contaminants that may be present. This may be done with a simple water rinse, or it may require more advanced methods such as sandblasting or chemical cleaning. 

We can advise on the most suitable pre-treatment process for your needs 


types of pre-treatments that we can offer 

Abrasive Blasting 

Abrasive blasting is a process in which a stream of abrasive particles is forced against the surface of a metal object to remove contaminants or to prepare the surface for painting or other finishes.

Amfin have several abrasive blasting cabinets and a large blasting room to allow effective surface preparation. We can accommodate both batch and large products. Our large blasting room has a size of 4600mm X 2200mm X 2000mm. 

The media types available are both dry and wet aluminium oxide, glass bead and plastic. We can also offer Semi-Controlled Abrasive Blasting. This gives Amfin flexibility when working with various metallic alloys and composites. 

We can offer our Abrasive blasting services on a range of materials including Nickel based Alloys, Magnesium Alloys, Aluminium Alloys, Titanium Alloys, Low Alloy Steels, Copper based alloys and Corrosion Resistant steels.

Vapour Degreasing

State of the art vapour degreasing unit using Trichlorethylene.

Vapour degreasing is a process of cleaning metals using a solvent vapour. The solvent vapour degreases the metal by dissolving the oils and other contaminants that are on the surface of the metal. This process is effective in removing light oils, greases, and other contaminants from metals. 

We operate a REACH compliant solvent vapour degreasing process meaning we have taken the measures to ensure that our chemical substances are used safely and responsibility.

We also have a suite of aqueous cleaning options which gives Amfin flexibility in component cleaning various materials.

Amfin can work with you to find the best cleaning and degreasing solutions for a wide range of materials and contaminants including Nickel based Alloys, Magnesium Alloys, Aluminium Alloys, Titanium Alloys, Low Alloy Steels, Copper based alloys and Corrosion Resistant steels. 

Chemical Processing 

Amfin’s state-of-the-art automated chemical processing facility ensures that Amfin can provide highly reliable and repeatable processing, whilst guaranteeing component traceability, environmental performance, and occupational health standards.

Our process tank sizes give us flexibility to treat small one-off batches to large batch serial production. 

We offer a range of different chemical processing techniques for metals such as Alkaline Cleaning, Acid Decaling, and Cleaning & Degreasing Using Perchloroethylene Solvent.

Pre-treatment FAQ

What is REACH? 

REACH is a regulation of the European Union, adopted to improve the protection of human health and the environment from the risks that can be posed by chemicals, while enhancing the competitiveness of the EU chemicals industry.

It also promotes alternative methods for the hazard assessment of substances to reduce the number of tests on animals.
