Pulper Door Redesign and Repair: How CMMC Delivered a Faster, Serviceable Solution for a Leading Paper Manufacturer

When a critical stainless steel door on a client’s pulper failed, their operation faced an immediate threat. The door, measuring 30 feet in length and weighing several thousand pounds, played a central role in daily operations. With production on the line, the client needed a fast turnaround and also wanted a redesigned door that would simplify future maintenance.

CHALLENGES

The repair presented multiple obstacles. Moving and servicing such a massive component required careful planning, and the timeline for completion was non-negotiable. Traditional repair methods would not address the client’s desire for ongoing ease of maintenance. The team had to balance technical complexity with urgent deadlines and the demand for a better long-term solution.

SOLUTION

CMMC responded by teaming up with the client to redesign the door for both strength and accessibility. The new design featured removable shafts and operating arms, enabling the most frequently serviced parts to be accessed without disassembling the entire assembly. Our machining and fabrication teams coordinated each stage of the process in-house to ensure precision and efficiency. The rebuilt door was completed and delivered ahead of schedule, fully upgraded for future serviceability.

RESULTS

With the new door installed, the client was able to return to normal operations quickly. The innovative design now enables maintenance crews to service key components in place, dramatically reducing downtime and complexity. This successful project highlights CMMC’s ability to deliver reliable solutions under pressure while finding new ways to add value for our clients.
