Zamak Injection

The company has a Zamak Injection section with Hot Chamber Pressure Injection machines, with a range of possibilities of up to 900 grams of capacity. All these machines are automatic and they also have peripheral equipment to handle the tasks of separating and recovering the casting, all in a continuous manner and as and when the parts are being injected.

All the manufactured parts which do not require a special polishing treatment are treated in our mass-polishing section. We have a traditional polishing by vibration system which gives our parts a surface finish that is perfect for a subsequent galvanic treatment.

We have the great advantage that we manufacture our own Zamak injection moulds, which results in a correct control of the process. Likewise, our customers leave the maintenance of these moulds in our hands, which guarantees them a controlled quality of the piece at all times.

Frequently asked questions about Zamak Injection

What is zamak injection?

Zamak injection consists of injecting molten metal into a mold to create metal parts with complex and detailed shapes. This material is an alloy of zinc with small amounts of aluminum, magnesium, and copper, which provides high fluidity and plasticity. Thanks to this, this technique allows the manufacture of highly precise parts with high-quality finishes. Furthermore, this process enables the mass production of objects with great strength and durability.
We have the great advantage of manufacturing our own zamak injection molds, which results in proper process control. Additionally, clients entrust us with the maintenance of these molds, guaranteeing controlled part quality at all times, since injected zamak can cause wear that can be minimized with good ongoing maintenance.

Advantages of manufacturing products through zamak injection

Zamak injection is a manufacturing technique for producing parts in series that offers a number of advantages, such as:

  • Allows the creation of parts with complex shapes and great detail.

  • Automated process for mass production.

  • Material cheaper than others like brass or aluminum, yet strong and lightweight.

  • Greater ductility and malleability.

  • Excellent finishes and high precision.

  • Savings in post-machining of parts.

  • 100% recyclable material.

Zamak injection process

As a company specialized in the zamak injection technique, we know the entire process and all its stages in detail. Above all, our team is trained to supervise each phase with the aim of ensuring quality in every part. This method consists of the following stages:

  • The zamak alloy is melted at around 400 degrees Celsius.

  • Then, the molten material is injected under pressure into the mold.

  • Once the part cools and solidifies, it takes the shape of the mold.

  • The part with the desired shape is then extracted from the mold.

  • After that, a vibratory or high-speed polishing is performed to achieve a perfect finish.

  • Finally, each part is inspected to ensure it meets the technical specifications and precise measurements of each client.

In our facilities, we have automatic hot-chamber pressure injection machines with a capacity of up to 900 grams. At the same time, all machinery is equipped with peripheral equipment for separation tasks and even recovery of the sprue. This allows us to offer very good stability in the molten zamak used in the process.

Therefore, all the parts we manufacture that do not require special polishing treatment are later processed in our mass polishing section. For this, we have a traditional vibratory polishing system that provides our parts with an ideal surface finish for subsequent electroplating treatment.

Additionally, and as a novelty, we have incorporated a high-speed mass polishing installation in our polishing section. This revolutionary system delivers parts with an extremely high-quality bright finish in minimal processing time, significantly improving the quality of the subsequent electroplating treatment.

Zamak injection or other types of injection?

A la hora de fabricar piezas en serie, la inyección de zamak tiene algunas ventajas frente a otros materiales como los plásticos o el aluminio. Destaca por su gran versatilidad para crear formas complejas y detalles muy precisos. También destaca por su facilidad para mecanizar y decorar los objetos, y su relación calidad-precio. Por ello, es una alternativa ideal para la producción de piezas metálicas de alta precisión dimensional como elementos de bisutería, automoción, electrónica, etc.
