Factory preparation affects unloading, installation, commissioning, product flow, maintenance and future expansion. Plan the building, utilities and handling route around the complete extrusion line before equipment drawings are frozen.
This guide identifies questions to coordinate with the machinery supplier, local engineers and the people responsible for operations and safety. It is not a civil, electrical or safety design. Project drawings and local requirements must be reviewed by qualified parties.
1. Start with the complete process flow
Map the route from raw-material delivery to finished-product storage. Include material preparation, feeding, extrusion, forming, cooling, haul-off, cutting or winding, inspection, packing, scrap collection and tool storage. Mark existing equipment that must connect to the new line.
The process map should show people, materials, waste and maintenance movement. Avoid placing a line only by its overall length; operating and service access often requires additional space beside and above the equipment.
2. Confirm building dimensions and access
- Usable floor length and width
- Clear height below beams, ducts and lighting
- Column positions, pits, drains and fixed obstructions
- Door, corridor and turning dimensions
- Unloading area and route from vehicle to final position
- Crane, forklift and lifting access for the largest machine section
- Floor condition and equipment-foundation requirements
Request shipping dimensions and lifting information before delivery planning. The final foundation and load checks should use the approved equipment drawings, not catalogue images.
3. Reserve operating and maintenance space
Provide aisles for operators, material loading, product removal and emergency access. Allow room to open electrical cabinets, remove screws or other service parts where required, change dies and moulds, clean material systems and move spare parts. Identify hot surfaces, moving equipment and elevated access that require project-specific controls.
Tooling can need its own storage and handling route. Heavy or delicate dies, mould blocks, calibrators and change parts should move between storage, preparation and the line without crossing finished-product or pedestrian routes unnecessarily.
4. Collect electrical information
| Electrical input | Planning question |
|---|---|
| Supply | What voltage, frequency and phase are available at the installation point? |
| Capacity | What connected and operating loads will the final equipment list require? |
| Distribution | Where are the main isolation point, cable routes and local panels located? |
| Protection | Which local protection, earthing and inspection requirements apply? |
| Environment | Do temperature, dust, moisture or other conditions affect the installation? |
| Expansion | Should capacity or cable routing reserve be included for future equipment? |
Ask the supplier for the final load list and interface drawings. A quoted machine power is not the same as the factory’s complete design basis because auxiliaries, pumps, heaters, chillers, air systems and material handling may be supplied separately.
5. Plan cooling water and temperature control
Extrusion and downstream equipment may require different water temperatures, flow conditions and cleanliness. Identify supply and return points, treatment, filtration, heat rejection, make-up water, drainage and winter or ambient limitations. Confirm whether the proposed equipment includes pumps, tanks, chillers or other temperature-control items.
Route water connections so they can be inspected and maintained without obstructing the production aisle. Record the buyer and supplier boundary for hoses, pipes, valves and connections.
6. Identify compressed air, extraction and ventilation
List every function that uses compressed air and confirm pressure, quality and demand on the final utility sheet. Review ventilation, heat release, fumes, dust and material-handling needs with local professionals. Some processes or materials may require dedicated extraction or controls that cannot be defined from the machine name alone.
7. Design material and finished-product flow
- Raw-material unloading, storage and identification
- Mixing, drying, dosing and feeding route
- Colour or formulation change procedure
- Finished-product cutting, coiling, stacking and inspection
- Packing, labelling and movement to storage
- Start-up scrap, rejected product and regrind route
- Quality samples and retained-product storage
Long rigid products, large coils, heavy boards or wound pipes may determine the handling area. Test the proposed route against the largest and most difficult product, not only the machine footprint.
8. Prepare for installation and commissioning
Agree who unloads, positions, connects and checks each item. Prepare lifting equipment, foundations, utilities, trial material, tooling, measuring instruments and assigned personnel before the commissioning date. Identify work that depends on local contractors or permits.
Connect the site plan to the factory acceptance test and commissioning records. Items that cannot be tested before shipment should have a clear site-verification method.
Factory information to send the supplier
- Dimensioned floor plan with columns, doors and fixed obstacles
- Preferred material-entry and product-exit directions
- Voltage, frequency, phase and available capacity
- Cooling-water source, return, temperature-control and treatment information
- Compressed-air and ventilation information
- Unloading, lifting and machine-positioning limits
- Existing upstream, downstream or inspection equipment
- Required operating, maintenance and future-expansion space
Frequently asked questions
When should the factory layout be reviewed?
Review a preliminary layout during quotation comparison and a detailed layout after the equipment scope is agreed. Recheck it when tooling, downstream equipment, utilities or product handling change.
Is the machine footprint enough?
No. The plan should include operating aisles, cabinet access, tooling changes, service removal, material loading, product handling, scrap movement and lifting routes.
Who should approve utility and safety design?
Use the machinery supplier’s final interface information as an input. Qualified local parties should complete and approve building, electrical, utility and safety work under the requirements that apply at the installation site.
