All our products have Technical Data Sheet (TDS) and Material Safety Data Sheet (MSDS). Do not hesitate to ask for more information.

Advantages of Moulds for Zamak Centrifugal Casting

The manufacture of parts using silicone moulds for zamak centrifugal casting offers numerous advantages over other processes. The main ones are as follows:

(castings or castings) of highly complex geometries
High dimensional stability
Molds with a much longer service life than molds for other materials
Reduced need, and therefore lower costs, in the use of tools
Faster melting cycles
Savings on post-melting machining
Easier surface treatment after part manufacturing (painting, chrome plating, zinc plating, etc.).

Manufacturing of Moulds for Zamak

The manufacturing process for moulds for zamak centrifugal casting begins with a study of the different variables that will determine the mould’s functionality and productivity.

The main variables are:

Thermal resistance
Mechanical resistance
Flexibility required to demold the part
Diameters and exact dimensions of the part to be produced
Mold part removal system

Choosing the right mold is essential to achieve maximum performance in centrifugal casting. Factors such as the type of alloy, the shape, and the size of the part directly influence the selection. Discover 3 simple steps to choose the right silicone mold and find the most suitable solution for each application.

During the mold casting process, we perform mold filling simulations, which allows us to guarantee a perfect result in the production of the parts and their dimensional stability.

Finally, we pay careful attention to the safety and technical information we provide to our customers to ensure that the production of parts with our zamak molds delivers the desired quality and cost-effectiveness.

Advantages of Zamak Centrifugal Casting

Zamak is a 100% recyclable material that can be purchased at affordable prices and offers excellent properties for part manufacturing. These unique characteristics make zamak the most cost-effective material for producing parts through centrifugal casting in silicone moulds.

Zamak is used to manufacture parts and components in a wide variety of industries: automotive, construction, electrical, hardware, electronics, jewelry, costume jewelry, sporting goods, decoration, clothing, handbags and telephony, among others.

Zamak is a material created by alloying different metals such as zinc, aluminum, magnesium and copper. The result of this combination of metals is a versatile material that is commonly used to create parts by centrifugal casting in silicone molds.

Zamak allows the production of parts with high precision and reproducibility of details. It has a number of characteristics that make it an ideal material for the production of parts:

Hardness
High shock and tensile strength
Flexibility, plasticity and adaptability to any form
Can be chrome plated, painted and machined
Clean material, attracts little dirt

What should you do with the sprues after each casting cycle?

Their partial recovery makes it possible to optimize the use of zamak and reduce waste, provided that the process is carried out under controlled conditions.
