The MMS-X is the manual version of the AMS-X. Like the automatic system, it uses a newly developed plate press.

The extremely compact and rigid construction allows you to obtain a perfect and bleed free end product. The press has 4 individually controlled clamp modules that ensure a high and even clamp force all around the product.

Low cost product development

The MMS-X is perfectly suited for molding process parameter optimization, small production batches or offline mold cleaning. It is ideal for low cost product development and to determine the process window for your product. Optimized parameters can easily be copied to the AMS-X, automatic molding system, for large scale production. Original Besi molds can be used on both the MMS-X and AMS-X.

User friendly

With its new UX-design, the MMS-X is the most user friendly manual molding system ever. It allows you to seamlessly switch over to an automatic system without any kind of long learning curve. Intuitive, easy and fast.
