A plastic extrusion machine does not have one useful price without a defined product and equipment boundary. A quotation becomes meaningful when the supplier knows what you plan to make, the material, the size range, the required output and which upstream and downstream functions must be included.
This guide explains the main factors that change a quotation. It does not publish a generic price because an unsupported number can hide missing tooling, downstream equipment, utilities or project services.
1. Finished product and raw material
The finished product is the starting point. Pipe, hose, profile, sheet, board, strap and pellets require different process stages. Resin type, formulation, recycled content, fillers and moisture sensitivity can affect screw design, feeding, drying, mixing, filtration and temperature control.
Send a drawing, applicable standard or sample photo. State the material as precisely as possible and identify any formulation information that the machine supplier must consider.
2. Product dimensions and tooling range
A single nominal dimension is rarely enough. The minimum and maximum size, wall or thickness range, layer structure, profile geometry, tolerances and surface requirements determine the tooling and downstream design. A wider production range may require more tooling, change parts or a different equipment arrangement.
3. Output target and operating schedule
Target output affects more than the extruder. Cooling length, haul-off, cutting or winding, material supply and finished-product handling must support the same production goal. State whether your target is an hourly output, line speed, daily production quantity or shift plan, and identify the product size used for that target.
4. Included equipment scope
Two quotations can have different totals because they include different boundaries. Ask each supplier to separate the main process equipment from tooling, material preparation, utilities, downstream handling and optional functions.
| Quotation factor | Question to confirm |
|---|---|
| Main process | Which extruder, forming or pelletizing stages are included? |
| Tooling | Which dies, moulds, sizing parts and change parts are included? |
| Downstream | Are cooling, haul-off, cutting, winding, stacking or handling included? |
| Material preparation | Are mixing, drying, feeding, dosing or filtration required? |
| Utilities | Which water, air, electrical or temperature-control equipment is included? |
| Project support | What documentation, commissioning scope, training or spare parts are listed? |
5. Control, inspection and automation
Control architecture, material dosing, marking, online measurement, detection, automatic cutting, winding and packing can change both equipment and integration scope. Describe the functions you need and the product requirements they must support. Avoid selecting an automation item only by name; define the result you expect it to achieve.
6. Factory conditions and destination
Voltage, frequency, phase, ambient conditions, cooling-water quality, compressed air, available floor space and lifting access can affect the proposed configuration. Destination and delivery terms also affect packing, documentation and commercial scope. These details should appear in the request for quotation rather than being resolved after an order.
Why supplier quotations may differ
A lower total may reflect a smaller equipment boundary, different tooling quantity, a different output basis or fewer project services. Compare proposals line by line and record every exclusion and assumption. The useful comparison is the equipment scope against the same product requirement.
Information to send for a useful quotation
- Finished product drawing, standard or clear sample photos
- Raw material, formulation information and recycled-content plan
- Minimum and maximum dimensions, wall or thickness range and product structure
- Target output with the reference product size
- Required cutting, winding, stacking, marking, inspection and packing functions
- Factory voltage, utilities, available space and destination country
- Existing equipment that the new line must connect with
Frequently asked questions
Can a supplier quote from pipe diameter alone?
A diameter can support an initial discussion, but it does not define the material, wall range, pipe structure, output, socket or joining method, downstream handling or factory utilities. Those details are needed before comparing a project-specific quotation.
How should I compare two extrusion line quotations?
Use the same product specification for both suppliers. Compare every included machine, tooling set, control function, utility item, document, spare part and project service. Record exclusions and the output basis separately.
Can RUNNING MACHINE prepare a quotation without final specifications?
Mac Lee can start by identifying the missing project information. A final equipment scope should follow the confirmed product, material, size range, output target and factory conditions.
Request a project-specific quotation
Send Mac Lee your product drawing, material, size range, target output, voltage and destination. We will use the information to discuss a suitable equipment scope.

Compare the supplier as well as the quotation
After aligning the equipment boundary, compare how each supplier explains selection, trial conditions, documentation and project responsibilities. Use the plastic extrusion machine supplier guide to prepare that review.
