When production at one of the UK’s leading fire door manufacturers was coming unstuck, Adkwik had the perfect solution to get things moving again.
Fire doors, by definition, are designed to stand firm in the face of extreme heat and smoke. They need to be made to the highest standards so they can give people time to escape and firefighters the chance to save the building.
The bonding process to make fire doors so robust involves pressing and bonding of veneers, laminates, and paper to chipboard door blanks, producing an effective barrier that can keep fire at bay for up to 2 hours.
The Problem
When one of the UK’s leading manufacturers was having problems with their initial bonding process, Adkwik were called in to help.
A thorough review of the production process identified two main issues:
- Pre-curing in the glue roller – due to their short open time.
- The slow press cycle was impacting throughput, and other processes, on the production line.
Our Product Solution
We trialled one of our best adhesives for veneer, the two component Prefere 4152 Urea Resin and the 5605 hardener to solve the problems. This UF resin adhesive for hot-press gave control over pot life and curing time and was an immediate success – effectively speeding up hot pressing times.
The result
Increasing open time alleviated precuring in the glue roller, while press cycle time was reduced by 45%. All of which meant production of the company’s life-saving fire doors could continue smoothly.
We also delivered onsite training to the whole production team – meaning these success measures could be maintained.
