Advantages of Zamak Die Casting for Part Manufacturing

Gurelan works with Zamak using hot-chamber die casting and has extensive experience in manufacturing technical parts for a wide range of industrial applications.

1. Dimensional accuracy and tight tolerances

One of the advantages of Zamak die casting highlighted by Gurelan is its ability to achieve greater dimensional accuracy and tighter tolerances compared with other die-casting alloys.

This level of precision can reduce the need for certain subsequent machining operations.

The die-casting process makes it possible to produce precision parts that are virtually finished, while also reproducing complex shapes and profiles directly in the die.

2. Longer die life

The working temperature of Zamak also has an impact on the service life of the dies used during the casting process.

According to data published by Gurelan, dies used for Zamak can last up to six times longer or more than those used for aluminium, and twice as long as those used for magnesium.

This longer service life can result in reduced die replacement and maintenance requirements.

3. Suitable for demanding decorative finishes

Zamak is particularly well suited to decorative electroplated coatings, including chrome and brass finishes.

This characteristic broadens the range of finishing options available for die-cast parts.

Gurelan has specific experience in manufacturing parts intended for demanding surface finishes and decorative coatings.

For this purpose, the company also has different types of machinery for post-casting operations, depending on whether the final finish requires, for example, painting or electroplating.

4. Manufacturing technical parts with very thin walls

Gurelan has experience in manufacturing technical parts with very thin walls using vacuum technology.

To work with this technology, its facilities are equipped with a centralised vacuum system that can be used simultaneously with any of its die-casting machines.

What does Zamak die casting offer in part manufacturing?

The properties of Zamak and its behaviour during die casting make it possible to combine dimensional accuracy, the reproduction of complex shapes and profiles, a reduction in certain machining operations, long die life, and a wide range of surface finishing options.

These characteristics are complemented by the possibility of using technologies such as vacuum-assisted casting to manufacture technical parts with very thin walls.

At Gurelan, Zamak die-casting production is complemented by in-house die design and manufacturing, as well as the equipment required to carry out the subsequent operations needed to achieve the final finish of each part.
