Baydur, a high quality technical material, allows the fabrication of any form.
This polyurethane (PUR) technology, which by definition is an amalgamator, allows us to over-inject any type of mould of any material. Thus, we can obtain parts including screws, nuts, metal structures, etc.
With this technology it is possible to work with different types of moulds. We can use low-cost moulds for prototypes or pre-series, then continue with reduced-cost moulds production because high pressure is not needed. The most suitable material is aluminium, which guarantees a high-quality finish and long durability.

Basically, the mould can be made of two materials:


  • With a wooden or other material carcass for prototype moulds.
  • With an aluminium smelting carcass. These moulds are for limited series.


The best material to build moulds. Its hardness makes temperature control easier and permits increasing the closing pressure of the mould.

  • Moulds of duraluminium. Laminated aluminium of great hardness. For blocks. Allows us to rapidly build high quality finished moulds, which can be embossed with acid etc. Its very good heat transmission allows the mould to be maintained at a suitable temperature.
  • Smelting mould of remechanized aluminium. With these moulds we can offer a very competitive mould price, and the heat transmition is also very good. However, this technology doesn´t offer a very good mould hardness and can lead to finishing problems (it can´t be embossed with acid), and doen´t have the hardness that aluminium does.

Each part must be considered carefully, taking into account all factors to decide which is the best material for the mould´s construction.
