In metal forming, feeding two sheets into a press instead of one can cause severe tool damage and costly downtime. Historically, double-sheet detection has often been associated with complex and expensive systems designed for high-volume automotive production. Contrinex is changing that with its smart double-sheet sensors, combining affordability with the flexibility required by modern manufacturing. 

Based on the company’s smart measurement technology, the sensors can be reconfigured to detect different metal types and sheet thicknesses, enabling manufacturers to process materials ranging from steel to aluminium without changing sensors. 

Configuration is equally flexible. Using the PocketCodr configurator and dedicated mobile app, technicians can enter the sheet material and thickness and set switching points within minutes, without programming. This approach is suitable where production involves consistent materials and rapid set up is necessary. 

Alternatively, the latest sensor version can be configured directly via any IO-Link Master. This allows detection parameters to be adjusted from the production system when changing between different materials, making the sensors particularly suitable for automated lines and mixed production. 

Contrinex has also designed the sensors to withstand the harsh conditions associated with stamping and forming. Its ‘Full-Inox’ technology uses a one-piece V2A (AISI 304) stainless-steel housing, providing resistance to chemical cleaning and physical impact. For particularly demanding applications, ActivStone-coated versions feature a rugged ceramic shield for additional protection against wear. 

By combining non-contact detection with flexible configuration, robust construction and multi-channel monitoring, Contrinex smart double-sheet sensors provide an economical way to protect valuable tooling and reduce unplanned downtime. 

PLUS Automation holds more than 2000 sensors in UK stock, supporting engineers with factory automation, process automation and machine safety solutions from Contrinex, Satron Instruments and ReeR Safety.

One of the UK’s largest independent workspace furniture designers and manufacturers, Gresham Office Furniture operates from a 200,000 sq ft factory on a 14-acre site in Bolton. In early 2025, the company installed three machines from BLM Group UK, including an electric press brake. 

The investment has enabled Gresham to bring all metal furniture component manufacture in-house, having previously outsourced around two-thirds of production. 

“The BLM acquisitions were part of a £7m investment last year that also included a new enterprise resource planning system and a Homag line for processing wood-based panels,” explains operations manager David Openshaw. “Insourcing all of our metal component manufacture has been a major benefit, as Brexit, swiftly followed by Covid and then war in Ukraine, all played into lengthening lead times from our subcontractors.” 

He continues: “We pride ourselves on quick deliveries to customers in 10 to 15 days from receipt of order, so we wanted total control over the supply of all office furniture components. Our latest investments have delivered exactly that.” 

The BLM STR Verde 2.6 m/100 T press brake features LED-guided tool positioning, with lights along the upper beam indicating precisely where punches and dies should be placed. The system also guides operators during sequential bending operations, reducing set-up times and errors. 

An infrared laser measures bend angles in real time, automatically compensating for spring-back and material variation. Optimised parameters can then be saved for future production. 

The press brake’s integrated EsaBend 3D software also accepts STEP files generated from Gresham’s Autodesk Inventor CADCAM system. EsaBend identifies available tooling, applies crowning and spring-back adjustments, and generates the G-code, helping ensure the first component is right-first-time.
