Material Recovery

Redefining Material Recovery. With the latest generation of Material Recovery Technology, Economa minimizes the excess weight of blanks to an absolute minimum – precisely, efficiently, and reliably. The result: lower material costs, higher capacities, and reduced waste – complemented by complete systems for industrial material flow.

NEW MATERIAL RECOVERY TECHNOLOGY – MRM Generation 2

For over 15 years, our Material Recovery Technology has proven its worth in real-world production – helping save tons of silver and hundreds of kilograms of gold.

Now, with MRM Generation 2, we’re introducing the next evolution of this success story – a technology refined for round gold or silver blanks, with or without edge, delivering even greater precision and performance.

Maximum efficiency. Minimal material use.
Until now, manufacturers had to allow a significant weight surplus to ensure the required minimum weight of a blank or bar. Our latest recovery technology reduces this surplus to an absolute minimum – unlocking new levels of efficiency and sustainability.

The benefits:

  • Faster, more stable production processes
  • Significant reduction in material consumption
  • Noticeably lower production costs

Experience how the MRM Generation 2 makes your production more efficient,
sustainable, and cost-effective.

SILVER – MAXIMUM PRECISION FOR BLANKS with & without rim

Automatic loading and unloading via SCARA Cobot GX20 with a working range of 1000 mm.
From ½ oz to 2 oz (Ø 25 mm – Ø 45 mm), format change required.

Maximum Performance – Minimal Losses
Our technology for silver blanks sets new standards in efficiency and precision.
With a feed rate of up to 50 pieces per minute and a throughput of up to 40 pieces per minute, the system ensures top productivity in continuous operation..

Dual-Core Design for Peak Performance
The dual-core design guarantees maximum stability and speed – ideal for series production under demanding conditions.

Nearly 100% Material Recovery
A specially developed vacuum recovery system collects 99.8% of removed material.
The chips are absolutely clean and free from contamination – ready to be re-melted immediately.
This ensures every gram of silver is used to its fullest potential.

Precision Down to the Last Milligram

  • Weight correction accuracy: ± 3 mg
  • Weight control precision: ± 2 mg

This level of precision guarantees consistent quality and minimizes waste.

Intelligent Real-Time Data Capture
All process data is continuously and transparently recorded in real time to ensure maximum traceability and process reliability.

Built for Continuous Operation
The system is engineered for 24/7 use – reliable, robust, and low-maintenance. 

GOLD – MAXIMUM PRECISION & MATERIAL EFFICIENCY

Round gold blanks from Ø 15 mm to Ø 50 mm, format change required.

Ultimate Precision for the Most Valuable Material
Our technology for gold blanks guarantees the highest accuracy, efficiency, and process reliability – specifically designed for precious metals where every milligram counts.

With a feed rate of up to 20 pieces per minute and a throughput of 15–18 pieces per minute, the system offers the perfect balance between precision and productivity.

Dual-Core Processing for Maximum Performance
The innovative dual-core design ensures uniform machining, exceptional stability, and consistent quality – even in continuous operation.

Efficient Material Recovery Without Loss
A specially developed vacuum recovery system collects 99.8% of removed material.
The chips are absolutely clean and free from contamination – allowing them to be re-melted immediately. This way, every gram of gold is utilized to its fullest potential.

Highest Precision

  • System accuracy: ± 2 mg or better
  • Calibrated scales for precise, certified weight control

This level of precision guarantees exact results and top quality for every single blank.

Real-Time Data for Complete Process Control
All relevant production data is continuously captured and analyzed in real time, ensuring seamless quality assurance and full traceability.

Designed for Continuous Operation
The system is engineered for 24/7 use – robust, reliable, and built for industrial endurance.

BARS – PRECISE MATERIAL RECOVERY FOR SMALL COMPONENTS

Gold, Platinum, Palladium, or Silver – 1 g to 50 g

Proven Technology, Now for Bars and Small Products
Building on the proven MRM Generation 2 technology, we now offer machines specifically designed for bars, wafers, and bar products.
They are standardized for products ranging from 1 g to 50 g.
The new systems are available in several versions – differing in throughput and price, but not in the precision of the trimming process.

Throughput and Performance – Tailored to Your Needs
Depending on the machine type, you can achieve:

  • Entry Version: 5 pieces per minute
  • Volume Version: 12–15 pieces per minute

Flexible Product Processing
All machines can handle products from 1 g to 50 g. Depending on the product, a format change may be required. Special sizes such as 0.5 g or 50–100 g are tested individually with real material to ensure optimal results.

Precision Down to 1 mg
The trimming process operates with an accuracy of ± 1 mg, allowing even the smallest material quantities to be precisely controlled.

High-Level Material Recovery

  • A specially engineered vacuum and filtration system collects 99.8% of removed material.
  • The chips are contamination-free and can be re-melted directly, ensuring the highest possible material yield.

Accurate Weight Control

  • Scales can be officially calibrated
  • Accuracy: ± 2 mg

Real-Time Data for Complete Control
All relevant production data is captured and analyzed in real time, ensuring maximum process security and full traceability.

Designed for Continuous Operation
All machines are built for 24/7 use – robust, reliable, and low-maintenance.

INTERNATIONALLY Protected

Of course, what we do with our machine is nothing entirely new. The way we do it, however, is. And this “how” is so special that it has been secured in international patents.

This also means that you are safe from counterfeits that promise more than they deliver – because as developers of this technology, we are proud to be the only manufacturer of these systems! We are constantly working on further developing the performance data of this machine in detail and improving the achievable results. Today, with the development of the second generation, we can present impressive values in the processing of blanks and bars. Our machines are available for gold, silver and other precious metals.
