Alocrom

It can also be applied prior to painting or powder coating and is used when a casting requires electrical conductivity. Alocrom provides protective coatings for castings without significantly changing their external surface. Benefits of Alocrom: Provides castings with a corrosion resistant surface Can give castings electrical conductivity Provides excellent pain adhesion [clear] Find out more about Alocrom chromate conversion coating We are passionate about our products and our customers and…

Anodising

Anodising

It takes advantage of the natural oxide film that is formed on the surface of aluminium once it becomes exposed to air. The thin oxide film that is created protects the metal making it more resistant to corrosion. Anodising thickens this natural film, as well as increasing the corrosion resistance of the casting electro-chemically, and provides the casting with a strong transparent coating. Thinner films are ideal for castings that…

Chromate Conversion Coating

It is classified as a conversion finish rather than an additive finish. It provides excellent corrosion resistance, it is conductive and results in no measurable build up. Chromate conversion is often used as an undercoat for paint or as an adhesive due to its excellent bonding properties that it provides. Benefits of Chrome Conversion: Provides castings with excellent corrosion resistance It is conductive Has excellent bonding properties Build up does…

Electrophoretic Coating

Electrophoretic coatings can leave castings with a coloured finish, however only one colour can be used in one electrophoresis tank at one time. Therefore, if the colour is uncommon higher costs are to be expected. The Process: The castings are immersed into solution in an electrified tank The paint is drawn to the casting The paint binds to the casting after electrons change the paint from ions in solution to…

Parylene

Parylene is also resistant to mould, chemicals, sterilisation (steam/gamma), moisture, salt spray, and other harsh environments. Parylene coatings are applied to castings at room temperature in a vacuum deposited chemical vapour deposition process. Benefits of Parylene: Provides castings with a corrosion resistant coating Low Dielectric (high voltage can be applied without the coating breaking down) Performs in Extreme Temperatures -200°C to +140°C Solvent & Acid Resistance Truly conformal on all surfaces…

Plating

Chrome Plating: Chrome plating aluminium is an electroplating process that allows a thin coating of chrome to be applied to the external layer of the casting. Chrome plating is most often used for the protection of the casting, but can also be used for decorative purposes. Benefits of Chrome Plating: Provides a good surface finish Will not rust Hard wearing High abrasion and corrosion resistance Polished Chrome: Polished chrome provides…

Powder Coating

Castings with minor surface flaws may benefit from a powder-coated surface, which can help to conceal and hide cosmetic defects. Powder coating is predominantly used as a decorative cover for castings that require a coloured or high gloss exterior. However, powder coating can also be used to increase the durability of a casting due to its hardened, scratch and corrosion resistant capabilities. The Process:  The powder and casting to be…

PTFE coating

PTFE Coating

PTFE can provide castings with: improved torque/tension control, good corrosion resistance, chemical resistance, abrasion resistance and a dry-lubricated low friction coating. Benefits of PTFE Coating: PTFE coatings are heat resistant and can operate continuously at temperatures up to 260°C. They also have the ability to withstand temperatures as low as -270°C. Does not contaminate material making it a safe option for pharmaceutical products and food handling. Not affected by continuous…

Sealant impregnation

The Process: Part preparation Impregnation Drain Cold wash Hot cure Benefits of Impregnation: Prevents leaks Reduces moisture entrapment Can reclaim expensive castings that would fail due to leakage Can prevent "blow-out" of entrapped gases during plating or painting processes

Shot Blasting

Wheel Blasting is an airless blast operation that uses a wheel with centrifugal force to propel the abrasive material against the casting. The wheel spins at high velocity and is a high efficiency blasting operation with quick cycle times. Wheel blasting utilizes metallic abrasives (such as stainless steel shot) that are available in different hardness’s. Wheel blasting is an automated process. Air Blasting works using suction that lifts abrasive media…

Ceramic Media Finishing

Vibratory Media Finishing

Ceramic and plastic media is durable and highly versatile and is therefore the most commonly used technique of mass finishing. Ceramic finishing media is made of silica and other minerals and abrasives that are combined, formed and fired at a high temperature producing a very hard cement-like product. Plastic media is moulded according to application and is used on softer materials such as aluminium and zinc to give an even…

Wet Spray Painting

The colour options for wet paint are unlimited and the thickness of the paint is dependant on the drawing requirement. The Process: 1. The casting should undergo surface pre-treatment and a suitable primer should be applied. 2. The casting is covered in a spray on pigment that is suspended in a solvent 3. The casting is rotated to ensure complete coverage Benefits of Wet Spray Painting: Relatively low overspray (85% of…
