Axial Powder Presses

Master your Material in Perfection

Axial powder presses enable efficient forming of functional and structural components close to their final contour, making it possible to produce even complex component geometries in large quantities and in a cost-efficient way without compromising quality. In many cases, reworking of the pressed parts thus produced will not be necessary.

DORST TECHNOLOGIES' state-of-the-art technology enables our customers to tap into more and more fields of application within their specific lines of business.

Axial powder and sizing presses by DORST TECHNOLOGIES combine pressing force, precision and speed with utmost reliability and field-tested usability to outstanding, economical production systems.

• Multi-platen technology
• Multi-material applications
• Cross hole and side compacting
• Split die
• Helical gear
• Threads
• Rotary modules for pressing punches

High-Efficiency Vacuum Extrusion Presses for all Kinds of Demands on continuous viscous Forming

Particular robustness, durability and wear resistance are the prominent features of our vacuum extrusion presses, which have been specially developed in terms of both machine design and technical engineering for the extrusion of heavy or very abrasive materials. The presses can be used almost universally, being able to be operated both in horizontal and in vertical position depending on the individual application. Key features include a central vacuum chamber for high material density and modern, frequency-controlled electric drives.

Another standard feature is the possibility to temper the material run very precisely in sections on the feed side as well as on the pressing side in order to achieve high-quality production results with high repeating accuracy.

Changeable extrusion worms of various geometric shapes, cylindrical or conical designs and a whole range of useful additional equipment result in a high degree of flexibility and adaptation to the individual demands and requirements.

A modern, network-capable process control system is used for visualization, operation and the evaluation of all process data.

Isostatic Powder Pressing - an Economical Shaping Process

Our isostatic powder presses enable fully automated shaping of ceramic tableware articles and technical functional and structural components close to their final shape, making it possible to produce even geometries and shapes with considerable demands on function and design in large quantities and in a cost-efficient way without compromising quality

The cold isostatic CIP pressing technique in elastic dies allows a homogeneous density distribution across the entire body, which helps to avoid distortions and cracking due to uneven shrinkage during sintering in large part.

One prominent aspect of all our dry isostatic pressing systems is the continuous, controlled automation of all process steps, the standard feature being the closed-loop controlled isostatic pressure curve.

A modern, network-capable process control system is used for visualization, operation and the evaluation of all process data.

Drawing on many years of experience in process control and in the development and the production of isostatic pressing tools and filling systems, we are today in a position to provide our customers with tailor-made systems both for stand-alone solutions and for entire production lines.

We offer turnkey solutions tailored to the specific application, starting with the granulate supply, the press and the tool system right up to automated post-processing.

Pressure Casting—for an Efficient and Flexible Shaping Process

Ceramic pressure casting enables the forming of tableware and sanitary ware articles close to their final shape, making it possible to produce even geometries with considerable demands on function and design in medium or large quantities and in a cost-efficient way without compromising quality.

DORST TECHNOLOGIES' mold and pressure casting technology, which has been refined over many years, allows our customers to follow the current market trends in a quick and flexible manner.

Pressure casting systems by DORST TECHNOLOGIES combine the requirements of the process with maximum reliability and field-tested usability to outstanding, economical production systems.

We offer our customers a differentiated portfolio of pressure casting systems suitable for a broad range of articles and applications.

Universal laboratory spray dryer for material development and pilot batch production

The SMART Lab Atomizer from DORST TECHNOLOGIES is the result of the intensive cooperation with our customers and is perfectly tailored to the special requirements of powder development in the laboratory environment.

Outstanding is the flexibility and mobility. As the world's first and only laboratory spray dryer, the entire spray dryer can be tilted 90° on its chassis. This means that the SMART Lab Atomizer can be used anywhere, even in confined spaces.

This flexibility allows easy access to all important points for operation, cleaning, set-up and maintenance - always safely and without stairs or ladders.

We have made a priority of ensuring that all functional units can be easily changed over by hand and without tools.

All parts that come into contact with the material are easy to clean or simple to replace.

We supply the SMART Lab Atomizer as a ready-to-use complete system with all accessories, nozzles, wash lance and suspension pump in a suitable stainless steel trolley. Simply connect to media and exhaust air and you are ready to go.

The main area of application is in advanced technical ceramics, for silicate ceramic bodies and for hard metals.

However, the SMART laboratory dryer has also already proven its effectiveness in the powder preparation of graphite, minerals, salts, polymers and certain organic substances.
