Virocast believes that each mould is more than just a tool. We believe that it is the heart of production. That is why we always design moulds with the greatest accuracy, which requires adequate amount of lead time.
By entrusting the design and manufacturing of your moulds to Virocast engineers, you entrust this task to people who have earned their reputation for their reliability and years of experience.
Moreover, the processes we implement are our strength that distinguishes us from the competition and makes us special partners for cooperation.
In the case of mould making, the process begins with a meticulous analysis of your product. Our engineers will inform you about all optimization possibilities. We will then decide together on the scope of the project. This process allows you to maximize production efficiency and minimize any unnecessary costs.
To produce moulds, we use the latest technological achievements in the form of simulation software and special techniques that increase the durability of mould surfaces, making them more resistant to high temperatures.
Aluminium die casting moulds
High pressure die casting moulds for aluminium alloys work on cold-chamber machines with high clamping and injection forces. Therefore, these moulds must be heavy and compact to ensure adequate heat capacity and strength.
The injection system in most cases is designed in the lower position, however the solutions of the central injection system are also commonly used.
At the design stage, it is crucial to carefully analyse the location of the metal injection into the die mould cavity, the path of the raw material flow, and the location of the vents system.
The combination of all these procedures together with extensive experience of Virocast engineers guarantees maximum mould lifespan and exemplary quality of the delivered products.
Zinc die casting moulds
The high pressure die casting moulds for zinc alloys work on hot-chamber machines, which due to the specific nature of a given raw material, can be characterized by lower clamping and injection forces compared to the aluminium die casting technology.
These machines have been designed for a much more efficient and faster operation, but to make it possible, it is necessary to provide a mould structure that will enable continuous operation without failure.
The gating system for casting moulds is mostly designed in a central position, but there are cases of products for which it is necessary to locate the gating system below the central point.
Die casting trim dies
The trim die is an extremely important tool in high-pressure die casting as it supports and automates the casting process. It is very precise in removing the gate system overflows and vents.
This tool finds its main application in serial production for components with openwork shapes or large-size products for which manual removal of the gating system is impossible.
Using a trim tool in mass production, we can significantly optimize the cost of post processing.
Plastic injection moulds
Plastic injection moulds work on injection moulding machines whose design visually resembles aluminium die casting machines, with the difference that the injection material is forced under pressure into the mould through an injection unit constructed on the basis of a screw system.
Injection moulds can be constructed as cold or hot runner moulds. The choice is dictated directly by production requirements and the product itself.
The moulds used to produce plastic components are designed in such a way that the product that is removed from the mould is immediately the final product, ready for packing and shipping without any additional processing required.
