How the processes at plastic injection molding company Promatrix have become more efficient and cleaner since the use of the Indus Neva. “By using the Neva, our machines no longer stop unintentionally.”
The Challenge
Scaling Production While Maintaining Efficiency
Promatrix began as a small shop 25 years ago and has grown into a full-fledged production powerhouse with over 60 employees. Under one roof, they handle everything from aluminum mold making to plastic injection molding—producing a wide variety of components for bicycles, rescue equipment, and truck trailers.
With such diverse production comes the challenge of managing a large variety of raw materials, specifically plastic granules. These arrived in 20-25 kg bags, creating logistical headaches:
- Loose bags cluttered the floor and were hard to transport.
- Storage was inefficient—bags couldn’t be stacked securely.
- Filling dryers was labor-intensive and prone to delays, causing machines to stand still.
- Spillage from cutting open bags meant messy workspaces and wasted raw materials.
As Promatrix moved into a new building, the need for a smarter, cleaner, space-saving system became urgent.

The Indus Solution
Neva: Transforming Raw Material Handling
Because the inventor of the Indus Neva system is also part of Promatrix, the company had the unique opportunity to test Nevas directly in their new facility. The results were immediate and game-changing.
Here’s how Neva optimized their process:
- Plastic granules are poured from 25KG bags into big bags (since 2025 by using the debagging machine Tunga), secured in Nevas.
- These Nevas are easily transported with pallet trucks and placed directly next to dryers.
- Dryers draw granules via vacuum hoses straight from the Nevas—automating supply, reducing manual handling, and eliminating downtime.
“We’re no longer dependent on how often an employee fills the dryers. The Neva system ensures a continuous supply—keeping production running smoothly,” says Joost Schuiveling, Head of the business office.
The Result
Results at Promatrix:
- 65% less storage space required: Nevas are stackable, optimizing vertical space.
- Machines no longer stand still: Dryers are continuously fed, no waiting for refills.
- Cleaner production areas: No more cutting open bags, no more spillage.
- Fully integrated into logistics: Nevas move seamlessly from storage to production.
“With over 100 Nevas in use, we’ve streamlined our processes while keeping everything tidy and efficient,” adds Johan Dijkstra, Head of Logistics.
The system was even adapted to provide additional flexibility. Two different Neva heights, a high and a low version, were introduced to accommodate varying material volumes. This solution allows the system to handle a wide range of materials while avoiding unnecessary variation in the overall setup.
