Industrial heritage of ERMAFA and Trusioma polymer equipment lineage

German mechanical engineering enterprise ERMAFA Sondermaschinen- und Anlagenbau GmbH based in Chemnitz traces its manufacturing lineage back to 1837 as the Haubold works.

Throughout the industrial era, the plant operated within the Plast- und Elastverarbeitungsmaschinen industrial combine, manufacturing heavy duty processing systems under the export brand Trusioma.

The engineering complex in Saxony supplied internal compounding units and extrusion lines to over fifty countries worldwide, establishing equipment fleets for hundreds of technical rubber plants.

Today the Chemnitz engineering facility maintains this technical heritage, carrying out custom machine building, modernization projects and equipment support.

Engineering design of EKN series heavy duty internal batch mixers

Trusioma heavy duty internal batch mixers spanning 50 up to 250 liters chamber volume process high viscosity rubber compounds containing heavy concentrations of carbon black and mineral reinforcements.

The enclosed mixing chamber features replaceable wear segments fabricated from abrasion resistant alloy steel designed to absorb severe shear friction stresses.

Synchronized dual wing rotors ensure uniform dispersive and distributive blending without heat buildup across polymer matrices.

A pneumatic floating ram maintains uniform downward pressure on the batch compound within the mixing throat, while a hydraulically clamped drop door allows fast bottom discharge into waiting open drop mills or transfer conveyors.

Technical parameters of two roll open mixing and warming mills

Industrial open mixing mills by Trusioma built in dimensions 1500x550 mm and 2100x660 mm perform rubber mastication, compound warming and continuous sheeting.

The heavy rolls are centrifugally cast from chilled iron, yielding an exterior chilled surface layer with hardness exceeding fifty units Rockwell C to shield against abrasive silica fillers.

Internal peripheral drillings permit rapid cooling fluid circulation during intensive mixing cycles, maintaining steady thermal process profiles.

The electromechanical roll nip adjustment features mechanical shear breaker plates that yield instantly, safeguarding the precision roll necks and rigid frame structure should tramp metal enter the roll gap.

Extrusion systems by Trusioma for profile shaping and strain filtering

Single screw and twin screw extruders from Trusioma deliver continuous forming of tire tread slabs, dense technical profiles and polymer pellet masterbatches.

Processing barrels incorporate bimetallic wear resistant alloy linings that preserve bore tolerances during long term operation with abrasive mineral compounds and tough fluoropolymer materials.

Feed screws are machined from high tensile alloy steels treated through plasma nitriding along flight crests and root surfaces.

A multi zone electric temperature control assembly equipped with proportional controllers maintains steady heat gradients along the extruder barrel length, preventing scorch degradation during elastomer processing operations.

Multi roll calender complexes for precision cord rubberizing

Trusioma calenders engineered in three roll, four roll and five roll configurations handle textile frictioning, tire cord skimming and thin elastomer gauge sheeting.

The rigid box section frame suppresses deflection under immense separating forces generated during the calendering of dense synthetic rubber compounds across wide commercial web widths.

To compensate for roll bending under load, Trusioma incorporates roll axis crossing hardware alongside hydraulic roll deflection bending jacks.

Dedicated fluid heating and cooling modules govern internal roll surface temperatures within tight degree boundaries, delivering uniform sheet thickness profiles and flawless surface smoothness across every batch roll.

Inspection protocols and preventive maintenance for Trusioma units

Sustained operating reliability of Trusioma processing machinery depends on scheduled inspection of journal clearances and fluid seal integrity.

On EKN internal mixers, maintenance technicians routinely monitor mechanical dust stop face rings, checking lubrication feed pressures and axial spring pack compression to eliminate leakage of powdered carbon black.

During scheduled overhaul campaigns on open mills, technicians conduct ultrasonic non destructive evaluations of roll journal fillets and measure wear across bronze bushing sleeves.

Rebuilding factory clearances, replacing roll gap thrust screws and fitting fresh chamber wear plates restores original machinery output over decades of plant operation.
