Die Casting Finishing

AME Pressure Die Casting offer a number of different Die Casting Finishes

Vibratory finishing

A vibratory finish is a process we use to remove sharp edges by de-burring components in high volumes.

The components are transferred into our fully automated vibratory equipment with media, liquid degreasing agent and/or a soap agent which improves the finish. Then, the components are passed through the bowl in a rotary action which vibrates forwards and upwards, once the cycle is completed it is automatically unloaded. The cycle time and media used is dependent on what finish is required.

Vibratory Polish is the same process as above but with the use of specific polishing media giving the component a brighter shinier polished effect finish.

All the finishes are determined by the following criteria:

 

  • The abrasive content of the media.
  • The shape and size of the media.
  • The amount of degreaser/soap agent used.
  • The of area in the bowl.
  • Process time.

Electro Barrell Plating

Electro Barrell Plating is a low-cost high-volume finish. Most metallic finishes are electroplated with only a small amount that are electroless. Most electroplating has an initial deposit of copper to protect the zinc substrate followed by a layer of nickel for corrosion resistance. Other layers can then be plated over the Cu/Ni layer

We can offer the below finishes for your Zinc Pressure Die components.

Alkaline Zinc with Clear/Blue, Black and Yellow Passivates with PS100 Sealant. All the passivates are trivalent are RoHs Compliant. The Full Enhanced trivalent passivate with PS100 seal has exceptional corrosion resistance exceeding 500hrs on neutral salt spray to first red corrosion.

Copper, Tin and Brass finishes are excellent for conductivity purposes. Nickel is more commonly used for cosmetic purposes.

Polishing

Polishing is the removal of metal by means of presenting a component onto a Linishing belt or brightening the metal by mopping or buffing after linishing. The linishing belt and mop rotates on the end of a spindle that is attached to a lathe. The belt has various grades of grit from fine to coarse dependant on how much metal needs to be removed.

Whatever process is required we can produce a high-quality finish in preparation for powder coating, painting, zinc plating etc by dressing split lines and/or finishing the component all over in preparation for nickel and chrome plating on your Zinc alloy component. Polishing is used for many domestic, commercial and industrial items, ranging from the automotive sector to the medical sector.

We also offer a brushed finish service which gives a brushed stainless-steel effect using satin and Scotchbrite mops.

Powder Coating

We offer various powder coating colours for both cosmetic and functional use.

Please contact us for more information regarding colours and textures.

Here at A.M.E we can supply your components with low bake powder, this cures between 160 degrees to 180 degrees.

This reduces quality issues such as blistering, this is not commonly used by our competitors, this improves the quality of the powder coating and reduces the reject rate at no extra cost.
