Custom & retrofit
PU machine retrofit and automation upgrades
Review the condition, compatibility and scope of an upgrade to your PU foaming machine or production line.
Send machine photos, nameplate data and the production issue you want to solve. BUJAVI coordinates the technical review with our manufacturing partner. The partner assesses the existing equipment, available drawings and component compatibility. For a new custom machine or line, include the required shot range, mould dimensions and available floor space.
What we can review
- Control system — PLC, touch screen, recipe storage, operator controls and alarm functions.
- Mixing head — Head type, mounting, material compatibility, and the smallest and largest shots required.
- Metering pumps — Output, ratio, viscosity, drive compatibility and signs of wear or drift.
- Tanks and temperature control — Tank condition, heating, cooling, agitation and sensor interfaces.
- Line automation — Conveying, mould heating, release spraying, demoulding and station layout.
- Safety functions — Guards, interlocks, sensors, emergency stops and alarms within the agreed retrofit scope.
How the retrofit is scoped
Document the machine
Send the nameplate, photographs, fault history and drawings you have. Include the downtime available.
Review feasibility
The partner checks interfaces, component availability and the condition of the equipment to retain.
Agree the work
The proposal identifies retained and replacement parts, installation responsibilities, timing and price.
Plan the installation
Agree who supplies parts, who performs the work and how the line will return to service.
Verify the result
Set acceptance checks in advance, such as shot weight, ratio, output or a specific cycle.
Retrofit questions
Can you assess equipment from another manufacturer?
Yes. Send the model and any available drawings so the partner can review compatibility.
Can existing components stay in service?
The proposal identifies which components can be retained after the condition and compatibility review.
How long will the upgrade take?
Timing depends on scope, parts availability and the shutdown window agreed for your site.
Send the machine details
Include the nameplate, affected component and the performance you need after the upgrade.
