Plastic injection and thermoforming
Injection Molded Parts as product casing


Plastic injection moulding and thermoforming are two plastics processing techniques widely used in the manufacturing industry. Metalworks Associates, as a leading supplier, can offer superior services in these areas.

Plastic injection involves melting plastic granules and then injecting them under high pressure into a pre-designed mould. Once cooled and solidified, the mould is opened and the moulded part is ejected. This method makes it possible to mass-produce complex parts with high dimensional accuracy.

Thermoforming involves heating a sheet of plastic until it softens, then moulding it using a die or mould. This process is particularly suited to the production of thin-walled parts in a variety of shapes, such as packaging, protective shells and decorative parts.

Metalworks Associates uses its expertise, state-of-the-art equipment and highly qualified team to offer versatile solutions that meet the diverse requirements of the industry.

Electropolished mechanical parts after machining made by Metalworks Associates


Mechanical and electrochemical polishing are two surface finishing techniques widely used in industry to improve the quality and appearance of parts. Mechanical polishing involves the use of abrasive tools such as grinding wheels, abrasive belts or rotating brushes to remove imperfections and smooth the surface of a part. This method is ideal for removing burrs, machining marks and scratches, while creating an even, shiny finish.

On the other hand, electrochemical polishing, also known as electropolishing, is an electrochemical technique that uses an electric current to remove surface layers of material from a workpiece. Workpieces are immersed in an electrolytic bath, and the electrochemical reaction removes surface roughness and defects uniformly. Electropolishing improves the corrosion resistance of metal parts while creating a smooth, shiny and highly reflective finish.

These two polishing techniques are complementary and offer distinct advantages depending on the specific needs of each application. Mechanical polishing is often preferred for removing larger defects, while electrochemical polishing is ideal for achieving a high quality finish on small or complex parts. Metalworks Associates use these mechanical and electrochemical polishing techniques, together with their expertise and state-of-the-art equipment, to provide high quality surface finishing solutions that meet the most demanding industry standards.

Surface treatments
Aluminium mechanical part with a Blue-dyed anodizing made by Metalworks Associates


Anodising is an electrochemical process used to strengthen and protect the surface of metal parts, mainly aluminium and its alloys. There are several anodising processes, each with specific characteristics and uses. Here is a description of some of the most common anodising processes: 

  1. Sulphuric anodising : This is the most common anodising process. It involves immersing the part in a bath of sulphuric acid and subjecting it to an electric current. This process creates a thick, resistant layer of aluminium oxide on the surface of the part. The thickness of the oxide layer can vary and determines the corrosion resistance, hardness and colour properties of the anodised surface

  2. Chromic anodising : This method uses a chromic acid bath to produce a thin, porous layer of aluminium oxide. Unlike sulphuric anodising, this technique is used for specific applications, such as improving the adhesion of adhesives or preparing for painting.

  3. Hard anodising : This process is a variant of sulphuric anodising. It is carried out at lower temperatures and higher currents, resulting in a much thicker layer of aluminium oxide. Hard anodising gives the surface increased resistance to wear, corrosion and scratches, making it a popular choice for demanding applications

  4. Colourless and coloured anodising: Anodising can be carried out without the addition of pigments to achieve a colourless finish that retains the natural colour of the aluminium. Pigments can also be added to the anodising bath to obtain a range of colours, offering aesthetic options for architectural or design applications.

These anodising processes offer great versatility and are used in various industrial sectors such as automotive, aerospace, electronics and architecture. The choice of anodising process depends on the properties required for the part and the desired aesthetics. Metalworks Associates offers bespoke anodising services, tailored to the specific needs of each project, to ensure high quality finishes and long-lasting protection for metal parts.

Copper flange after chemical nickel plating made by Metalworks Associates


Nickel plating is a technical electrolytic coating process widely used in industry to protect and improve the surface properties of metal parts.

During the nickel plating process, the part to be coated is immersed in an electrolytic bath containing nickel salts. An electric current is then applied, causing the chemical reaction of electrodeposition of the nickel on the surface of the part. This nickel coating offers a number of advantages, such as improved resistance to corrosion, wear and abrasion. It also makes the surface harder, improving the durability and longevity of parts.

Nickel plating is frequently used in the aerospace, automotive, electronics and medical industries, where mechanical properties and corrosion protection are essential.

Metalworks Associates applies high-quality nickel plating processes using their technical expertise and state-of-the-art equipment, ensuring consistent, high-performance nickel coatings to meet the industry's most stringent requirements.

Heat treatments

Heat treatments are controlled heating and cooling processes applied to metallic materials to modify their crystalline structure and mechanical properties. Here is an explanation of the most common heat treatments:

  1. Annealing : Annealing involves heating the material to a specific temperature and then allowing it to cool slowly. The aim of this process is to eliminate internal stresses and make the material more malleable and less hard. It also improves ductility and reduces the risk of cracking.

  2. Quenching: Quenching is a heat treatment that involves rapidly heating the material to a high temperature, followed by rapid cooling by immersing the material in a medium such as water, oil or air. This operation increases the hardness of the material, but can also make it more brittle.

  3. Tempering: Tempering is carried out after quenching and involves reheating the material to a lower temperature than that used for quenching. This process reduces excessive hardness and improves toughness while maintaining a certain amount of hardness.

  4. Normalising: Normalising is similar to annealing, but the material is cooled in ambient air instead of being cooled slowly in a furnace. This treatment improves the uniformity of the material and reduces internal stresses.

  5. Cementation: Cementation, also known as case hardening, is a heat treatment used to increase the carbon content at the surface of the material. This creates a hard, wear-resistant layer, while the inside of the material remains softer and more ductile.

  6. Surface hardening: This treatment is similar to quenching, but is used to harden only the outer surface of the material, leaving the interior softer.

Heat treatments are essential for improving the properties of metallic materials and adapting them to specific industry applications. Metalworks Associates offers high quality heat treatments, carried out with precision and control, to ensure high-performance materials that meet the specific requirements of each project.

Golden Sponsorhip: Metalworks Associates supplies technical 5-axis aluminium parts to the TU-Fast Eco in München

München - 27/04/2023

The much-anticipated day has finally arrived! On Thursday, April 27th, the TU-Fast Eco team at the TUM, Technische Universität München, raised the curtain and unveiled muc023 to the world, showcasing the future of mobility. The hyperefficient urban vehicle boasts an optimized aerodynamic shape, lightweight construction, and minimal energy losses across all systems.

The Muc023's roll-out event took place at the Verkehrszentrum of the Deutsches Museum and was also attended by Bavarian Minister of Science Markus Blume, Munich's second mayor Katrin Habenschaden, and TUM President Prof. Thomas F. Hofmann.

Markus Blume appreciates the fine line of the Muc023. He attended the roll-out of this cutting edge Electrical Vehicle that was soon about to outperform and break new records on the Nogaro Circuit.
