when you need them
Sigma Industries manufactures and supplies high-quality change parts and trolleys designed to support fast, accurate, and repeatable changeovers in conveyor and production systems. Working closely with customers, we produce precision-engineered change parts that ensure consistent alignment, reliable operation, and minimal downtime across a wide range of industrial applications.
Our change parts can be manufactured directly from samples, with no drawings required, allowing us to replicate and improve existing components quickly and accurately. To support efficient storage and handling, change parts can be supplied and stored on dedicated trolleys, clearly organised and ready for rapid deployment during line changeovers. From individual components to fully configured trolley systems, Sigma Industries delivers practical, durable solutions that help improve changeover efficiency and maintain consistent production performance.
Change Parts & Trolleys
Sigma Industries manufactures and supplies precision change parts and trolley systems that support fast, accurate, and repeatable changeovers in conveyor and production operations. Our solutions are engineered to minimise disruption, helping reduce downtime and maintain consistent production output. We can colour code parts individually or colour code complete trolleys, to help minimise error and maintain good working practice.
Designed to Reduce Downtime
Frequent changeovers can significantly impact productivity if not managed efficiently. Sigma Industries designs change parts that allow quick removal, precise alignment, and reliable refitting, helping operators complete changeovers faster and return lines to full operation with confidence.
Typical Change Parts Supplied
We manufacture a wide range of conveyor and line change components, including:
-
Star wheels
-
Ploughs
-
Scrolls
-
Back guides
All components are engineered to integrate seamlessly with existing equipment.
Manufactured from Samples
Where drawings are unavailable, Sigma Industries can manufacture change parts directly from customer samples. This enables accurate replication of existing components, reduces lead times, and ensures correct fit without the need for redesign.
Changeover Trolleys
To support efficient storage and handling, change parts can be supplied and stored on dedicated trolleys, keeping components organised, protected, and immediately accessible during changeovers.
Industry Experience
With over 45 years of experience supporting the food and drinks industry, Sigma Industries delivers practical, reliable changeover solutions designed for hygiene-critical, high-throughput environments.
Star Wheels & Guides:
These are often used in bottling and packaging lines to manage the flow, spacing, and orientation of containers as they move into or out of machinery.
Lane Dividers/Switches:
These mechanisms, which can include gates, pushers, or servo-controlled sweeps, sort products from one line into multiple lanes or vice versa.
Feed Screws or Scrolls (Timing Screws):
Used to consistently space, orient, and time the movement of individual products along the line, especially for precise operations like labeling or filling.
Trolleys:
For handling change parts, specialised pucks or pallets are used to hold the item in a fixed, known location on the conveyor, which can then be circulated and located with precision tooling at various stations.
Adjustable Components:
Many modern systems incorporate adjustable side rails and guides that can be quickly repositioned rather than fully replaced, allowing for faster changeovers.
Colour-coded:
to simplify identification and ensure the correct part is used for a specific product run.
Quick Release:
Designed for quick-release mechanisms to speed up the manual changeover process.
