Improving adhesive bonding processes has streamlined production, reduced costs and removed production hassle for one of the UK’s specialist manufacturers of fire and security doors
The Problem
This busy manufacturer provides a complete fire door set solution and recent regulation change has seen demand for there products soar. This increased demand has led to a very busy operation including two shifts and non-stop door production. They didn’t have time for production defects and when it started to occur it created significant production reworking costing them time and money.
To make the doors the company was bonding both paper and laminates to chipboard cores but had issues with their veneered doors bubbling or rippling after pressing.
They have the following press set up:
- Top & bottom press plate temp: 85C
- Pressure: 3 bar
- Timing (paper veneer): 8min
- Timing (laminate): 12min
The issue was not obvious until the doors were painted through an automated paint line. Manually sanding the ripples and bubbles out of the doors was possible… but this added extra labour and did not solve the root cause of the problem.
The manufacturer needed to identify what was behind the issue and find a solution. They turned to Adkwik to help them solve this problem.
