The manufacturing of electro and medical products requires a clean working environment. PROMESS has designed the assembly press series UFM Precsion HD4 (Hygienic Design) for applications in cleanroom environments, certified according to cleanroom class ISO 4 (DIN EN ISO 14644). A well-conceived design of sealings, filters and surface refinement minimises the particle emission of the assembly press and allows for a precise production without contamination of the environment. All components of the system comprise of FDA approved material or are coated with FDA approved materials. The complete system is easy to clean.
