Zinc pressure die casting improves perception of car interior value

By using zinc pressure die casting is possible to obtain innovative shapes and unconventional finishing: in fact zinc alloy is the ideal material to produce components or products aligned to customers’s aims, by reaching higher aesthetic values.

Zinc pressure die casting allows a better mix of strength, toughness, rigidity, bearing, performance and economical castability if compared to other materials. Its properties are better than other materials such as aluminum, magnesium, bronze, plastic and other cast irons in case of high aesthetic value requirement.

SST – Salt Spray Test Resistance: focus on automotive sector

SST – Salt Spray Test Resistance: focus on automotive sector

In this article we are going to analyze a particular corrosion test called Salt Spray Test (SST) normally used to test coatings for automotive parts, in order to test their salt or mist resistance.

Salt Spray Test (SST) is a really widespread corrosion method, applied in order to check materials and surface coatings corrosion resistance. This kind of test is an accelerated corrosion test which produces a corrosive attack to coatings to evaluate, after a pre-determined period of time, if they can be used as a protective finish. The duration of Salt Spray Test depends on coating corrosion resistance: if the coating has high corrosion resistance, the testing period is longer before the appearance of corrosion.

It can be used for different materials such as: zinc, phosphate surfaces, electroplated chromium, nickel, copper and tin and also for paint coating.

Moreover Salt Spray testing is fundamental in order to evaluate product or component corrosion aimed at outdoor uses or in cold or wet environments.

Summarizing is possible to say that Salt Spray test is used to:

  • Analyze corrosive resistance of different materials and finishing
  • Measure the corrosive inclination when a metal or coating is scratched
  • Determine coating adhesion and corrosion creep
  • Evaluate corrosion resistance in a marine environment

Products without SSL resistance would corrode under saline air influence.

Cost Reduction with Zinc Alloys in the Automotive Industry


Zinc alloys is very versatile material. A combination of factors make it unique material from various perspectives, certainly the cost aspect.

In according to that, the application of die cast zinc alloy components in the automotive industry can be an efficient solution to reduce production costs whilst maintaining the high levels of resistance, service life and hardness required by that sector.

Following are some of the advantages that make zinc a strategic material when striving for cost reduction for a company that is active in the automotive sector.

These are factors to bear in mind when considering zinc as an option:

  • Production costs
  • Surface treatments
  • Machining precision
  • Technical characteristics
  • Energy savings

Metal corrosion in automotive parts

Metal corrosion in automotive parts


Just like atmospheric environment, which is different for corrosivity depending on where people are located in the world, the same is for metal corrosion in automotive parts: for example in Sweden the automotive environment is quite aggressive caused by humid climate and by the use of de-icing salts causing metals corrosion.

Corrosion is a natural process, that changes metals to a more stable form, it is the gradual materials destruction due to chemical or electrochemical reaction with the environment.

Zinc Die Casting Finishes for Building Sector


One of the main fields of application for zinc alloy products is surely the building sector. Depending on the position of the component and its visibility, various surface treatments are required to improve aesthetics and functionality.

In this article we will discuss zinc die casting finishes applied to the most common products or components in building sector:

  • Chroming
  • Gilding
  • White zinc plating
  • Painting

Zinc die casting finishes: experience makes the difference

Zinc die casting finishes: experience makes the difference


Zinc die casting finishes are processes applied in order to modify manufactured item, product or component surface with the purpose of reaching client requirements and improve functional and aesthetical quality of a product.

Zinc die casting finishes can be divided into different categories: processing techniques and finishes.

The first type concerns mechanical processes applied in order to change product surface without applying any particular coating, while the second type regards every galvanic or aesthetic treatment requested by clients.

Is important to say that usually zinc die casting finishes requirements are given by clients, but die caster experience can make the difference: a vertical supplier for zinc material is able to suggest the best way to improve processes but also costs, maintaining product performances.

In fact in this article we are going to explain the reason why this is possible.

Die casting defects: Internal and Superficial

Die casting defects: Internal and Superficial


The main die casting defects which occur during die casting can be divided in categories related to different phases of production process.

These defects occur during different moments:

  • Die casting
  • Pre-Finishing
  • Machining operations
  • Surface finishing

In particular in this article we are going to analyze defects related to the first category: die casting.

Is important to remember that not every defect can be avoided during die casting phase, but is necessary to focus on mould design. This happens because during production phase is possible to act on a limited number of parameters and sometimes to solve a problem the designer can only modify mould design.

What is black zinc treatment?

What is black zinc treatment?

Black zinc is a zinc plating treatment which gives aesthetic and functional characteristics to product or component surface.

In this article we are going to deeply and technically analyze this treatment but, first of all, it could be useful to have an introduction on zinc plating main characteristics and which different types are most commonly used.

Optimizing die casting surface finish for AUTOMOTIVE

Optimizing die casting surface finish for AUTOMOTIVE


The automotive industry has requirements that are both functional and aesthetic when designing a component which should be produced by using die casting process. 

The main aspect a die caster will seek to ensure is oxidation prevention, therefore requirement on component, is to extend resistance to atmospheric agents. For instance, when parts are hidden from view as inside door panel, finish objective is a longer life cycle avoiding surface oxidation.

It is furthermore important to emphasize that zinc does not generate red but white oxidation, called salification. Salification process is analyzed when product is exposed to an accelerated oxidation process by undergoing the worst conditions to provoke results. For these specific reasons, automotive industry commonly requires a number of SSL resistance which is then certified by results of tests.

These requirements however change based on component’s position inside vehicle: if the product is placed internally it will only require functional treatment, if visibly positioned, it will also require aesthetical treatment.

In order to obtain these goals, functional and aesthetic, various types of die casting  surface finish are available. 

In the following article we will focus on:

- CHROMATING

- TECH-SEAL

- BLACK ZINC

How die casting finish can help reducing product cost


It may seem impossible but it is not! Reducing costs adding a die casting finish is really possible. The trick is just trusting your supplier and its expertise: collaboration with it in co-design terms. Starting a collaboration with suppliers can help clients to find a suitable solution to obtain the same requirements: with new solutions, but less costs.

 

Hereunder we are going to explain how is possible to obtain a product cost reduction, explaining it through three case studies applied.
