IN Brief:
- WDS has introduced detectable knobs, grips, handles, and positioning components for regulated food and packaging machinery.
- The range combines high-contrast blue polymers and metal-detectable polymers to support optical inspection and inline metal detection.
- The launch reflects a stronger design-stage focus on contamination control, where machine hardware is specified around HACCP and fragment detection.
WDS Components has launched a new range of visually detectable and metal detectable machine parts aimed at regulated production environments, with food processing and packaging among the main target sectors.
The range includes clamping knobs, star grips, wing knobs, adjustable handles, machine handles, pull handles, and positioning components. These are routine operating elements on guards, access points, and adjustable assemblies throughout production equipment, but they can also become a contamination risk if damaged in service.
WDS said the new parts have been developed for food processing, bakery, dairy, pharmaceutical, and packaging lines, where hygiene controls and audit requirements are tightly defined. The company is offering two main formats. Visually detectable versions use a high-contrast blue polymer designed to stand out during manual checks or optical inspection, while metal-detectable versions use an engineering-grade polymer containing a homogeneously dispersed metallic additive so fragments can be identified by inline metal detection systems.
That split reflects the reality that detection routes vary by application. In open equipment, visual contrast may help during inspection, changeover, or cleaning. In enclosed conveying systems or opaque product streams, visual identification may be much less reliable, making metal-detectable polymers more suitable where component fragments need to be found before product leaves the line.
WDS said the detectable materials conform to EU10/2011 and FDA requirements and offer a detection volume of at least 0.027 cm³. That places the range squarely within the type of design-stage contamination control now being considered more closely in machine specification and retrofit work, particularly where frequently handled hardware sits close to a defined critical control point.
The broader significance lies in where contamination prevention is being addressed. Rather than relying entirely on downstream inspection to catch foreign bodies, processors and machine builders are increasingly looking at the machine itself as a controllable source of fragment risk. Detectable hardware supports that shift by making smaller failures easier to identify within existing inspection systems.
For OEMs, that turns a niche component choice into a more formal specification decision, especially on equipment designed for high-hygiene or audit-heavy environments. For processors updating legacy assets, it offers a targeted route to improving contamination controls without redesigning complete assemblies.
WDS said technical data and CAD drawings are available for integration into new builds and retrofit projects. Whether that drives broader uptake will depend on how easily the parts can be introduced without compromising durability, ergonomics, or maintenance access, but the direction is clear enough: machine hardware itself is coming under closer scrutiny as part of wider food safety control strategies.
