Process-Reliable Hydraulics and Compact Cooling Technology for Injection Molding and Extrusion
Modern plastics machinery must guarantee maximum productivity with consistent component quality. Especially in injection molding machines and extrusion lines, stable processes, short cycle times, and reliable temperature control are crucial for economical continuous operation.
Universal Hydraulik is an experienced partner for OEMs and machine builders, developing hydraulic system solutions as well as compact cooling and heat exchanger solutions specifically for plastics machinery.
Hydraulics as the Key to Availability and Process Quality
Hydraulic systems in plastics machinery must operate reliably, quietly, and with minimal maintenance. A constant pressure supply, reliable hydraulic oil cooling, and a robust design for long operating times are essential.
Universal Hydraulik develops field-proven solutions that can be optimally integrated into machine designs โ even with limited installation space.

Frequently Asked Questions about Applications in Plastics Machinery
Oil/water heat exchangers are used in many applications, especially when stable hydraulic oil cooling is required. Tank-mounted heat exchangers are often used when installation space is limited.
Universal Hydraulik assists in selecting the appropriate solution based on the machine design.
Constant oil temperatures ensure reproducible machine movements, consistent cycle times, and reduced wear. Reliable hydraulic oil cooling increases machine availability and reduces downtime costs.
A tank-mounted heat exchanger is particularly suitable when:
- available installation space is limited
- external piping needs to be reduced
- a compact and clean unit solution is required
The combination of cooling and filtration reduces the number of components and interfaces. This saves space, lowers assembly costs, and increases operational reliability, as oil purity and temperature are considered together.
Yes, a retrofit is possible in many cases. Universal Hydraulik checks the cooling capacity, connection configuration, pressure range, and existing temperature values โโof the machine.
For a quick technical evaluation by Universal Hydraulik, the following information is generally required:
- Desired cooling capacity (kW)
- Oil temperature at inlet and outlet
- Oil and water flow rates
- Medium (e.g., water or water/glycol)
- Operating pressure and installation type (e.g., tank installation)
