Customized tools

Choosing the right plastic installation for your application is very important for the high performance requirements of your system. Therefore we offer our cooling tower customers the free cooling tower design software, which you can use on our website after registration. This gives you valuable information for choosing the right cooling tower fills. Furthermore, our team is naturally at your disposal.

Thanks to our own machine and tool construction, we can customize a customer design flexibly and quickly.

However, this requires close cooperation with our engineers, who can pay particular attention to the necessary details of the microstructure or the technical refinements of the moulding tools. Due to the diverse production possibilities, we can make almost any customer-specific tool design and quickly present the samples. Only after your final approval can production of the customer-specific designed tool commence using our production lines. Obviously, these exclusive products are available solely for you.
