Extrusion blow molding machine cost varies widely because the term covers very different equipment. A small semi-automatic machine for lightweight bottles, an automatic system with deflashing, and an accumulator head machine for large products are not in the same price class.
The main machine is also only part of the investment. Molds, auxiliary equipment, automation, packing, and shipping all contribute to the final project cost. Even two requests for a “5 L blow molding machine” can produce different quotations when the bottle weight, dimensions, handle, output target, and supply scope are different.
How Much Does an Extrusion Blow Molding Machine Typically Cost?
The following examples show four representative configurations using a 65 mm screw.
These rounded prices cover the main machine only. Molds, auxiliary equipment, packing, and freight are excluded. Prices may fluctuate with the detailed configuration, component brands, voltage, material costs, exchange rates, and quotation date. An updated quotation should be based on the actual bottle.
Why Is There No Single Standard Price?
A useful quotation starts with the actual bottle. Capacity alone does not define the machine.
Two customers may both produce a 5 L HDPE bottle. One may be a lightweight, handle-free detergent bottle. The other may be a heavier handled chemical container requiring a larger mold and better wall-thickness distribution. The HDPE blow molding machine price will differ because the machine and mold specifications differ.
For budgeting, use this structure:
Total Project Cost = Main Machine + Mold(s) + Auxiliary Equipment + Automation + Packing / Shipping + Other Project Costs
This is why the right extrusion blow molding machine should be selected from the product, not only from the stated bottle volume.
What Determines the Machine Price?
Product Dimensions and Bottle Weight
Bottle width, height, depth, neck, and handle determine the mold size, platen area, opening stroke, and removal space. A wide, low container can require more mold space than a taller bottle of similar capacity.
Weight affects the material required per cycle. A heavier bottle needs suitable plasticizing output, die-head capacity, and cycle matching. Two bottles with the same capacity may therefore need different extrusion systems.
Machine Size and Extrusion Capacity
Single Station, Double Station, and Die Heads
Two machines described as “5 L blow molding machines” may use different screw diameters, plasticizing capacities, die heads, mold spaces, and clamping structures. These differences change both capability and cost. A specification sheet tells more than the model name or advertised maximum volume.
A double-station machine has additional mold-moving assemblies, hydraulic circuits, controls, guarding, and frame structure. For a standard setup producing the same bottle on both sides, two matching mold sets are normally required. Its cost should be considered together with cooling time, output, labor, and the second mold set.
Small bottles may use one, two, four, six, or more die heads. More heads change the mold layout, cavity quantity, extrusion demand, material distribution, and cooling. More heads are not automatically better; the arrangement must match bottle weight, machine output, mold space, and cycle time.
Semi-Automatic vs Automatic Configuration
Semi-automatic machines usually rely on operators for bottle removal, trimming, and handling. Automatic machines can add take-out, deflashing, conveyors, scrap handling, guarding, and more control hardware. These systems explain much of the automatic blow molding machine price difference.
The better choice follows production volume, labor cost, product shape, factory management, and investment budget. See our comparison of semi automatic vs automatic blow molding machines for more detail.
Parison Thickness Control
A parison controller changes the die gap during extrusion to distribute material along the parison. Simple small bottles may not need it. Handled jerry cans, irregular containers, and products with large thickness differences between the shoulder, body, and bottom benefit more from this control.
The controller, actuation system, die-head integration, and programming add cost. The quotation should state the control points and actuation method. Read more about controlling parison thickness in extrusion blow molding.
Servo, PLC, and Main Components
“Servo” can mean a servo-driven hydraulic pump or additional servo-controlled movements. Confirm what it controls, along with the motor, drive, pump, and hydraulic configuration. The word alone does not prove that a machine is better.
Also request the PLC, touch screen, inverter, hydraulic valve, pump, pneumatic, and main electrical component list. Actual brands, series, and local availability are more useful than the phrase “international famous brands.”
Is the Blow Mold Included in the Machine Price?
Machine and mold prices should normally be checked separately. Mold cost reflects bottle size, cavities, mold material, handle and neck structure, cooling, pinch-off design, machining, testing, and trimming structure.
A double-station machine usually needs two matching mold sets when both stations produce the same bottle. Before comparing prices, confirm the number of molds, cavities, material, and included testing.
Main Machine Price vs Complete Production Line Cost
For a new standalone project, divide the equipment into three groups:
| Group | Typical Items |
|---|---|
| Usually required | Main machine, mold, air compressor, air tank, chiller or cooling system, material loader |
| Based on factory setup | Mixer, crusher, additional loader, existing air or central cooling system |
| Optional automation | Take-out, deflashing, conveyor, scrap handling, leak testing, downstream handling |
A suitable compressor, chiller, or crusher already in the factory may be reused. Its capacity and specifications must match the new machine. See our guide to auxiliary equipment for an extrusion blow molding machine for selection details.
Three Practical Project Examples
| Project | Why the Cost Structure Changes |
|---|---|
| Small HDPE bottle | Light bottle, small mold, modest extrusion demand, and a simple mold; one or several heads may be used, while parison control may not be needed. |
| 5 L handled bottle | Larger mold space, handled mold, stronger clamp, better cooling, possible parison control, and two mold sets for a double-station setup. |
| 20 L jerry can | Larger screw, die head, mold, frame, clamp, cooling system, and higher-capacity auxiliaries move the project into another machine class. |
Machine price does not increase according to liters alone. Structural changes drive the jerry can blow molding machine price. For related purchasing points, see our HDPE bottle blow molding machine buying guide.
Costs Buyers Sometimes Overlook
Items outside the headline EXW price may include a second mold set, voltage customization, parison control, deflashing, conveyors, a crusher, export packing, inland transport, FOB charges, sea freight, site utilities, and technician travel where applicable.
Mark each item as included, optional, buyer-supplied, or excluded. This prevents a main-machine quotation from being mistaken for the amount required to start production.
Why Can Two Similar Quotations Be Very Different?
Compare what is included before comparing the final number:
Compare what is included before comparing the final number:
| Area | What to Compare |
|---|---|
| Core machine | Screw diameter, plasticizing capacity, die head, mold space, opening stroke, clamp |
| Production setup | Stations, die heads, cavities, parison controller, automation |
| Drive and controls | Servo function, pump, PLC, electrical, hydraulic, and pneumatic components |
| Mold and auxiliaries | Mold quantity and material, compressor, chiller, loader, mixer, crusher |
| Commercial scope | Voltage, spare parts, testing, packing, delivery term, services, exclusions |
A lower quotation is not automatically better. A higher quotation is not automatically better either. The useful question is: What configuration or scope explains the difference?
What Information Is Needed for an Accurate Quotation?
Provide the following:
Product photo, drawing, or sample
Bottle capacity and weight
Overall dimensions
Neck and handle details
Material, such as HDPE or PP
Required output
Voltage and frequency
Preferred automation level
Existing auxiliary equipment
Planned working hours
Bottle weight and external dimensions are often more useful than capacity alone. They allow the manufacturer to confirm the machine size, extrusion system, mold space, die heads, stations, trimming method, and auxiliaries.
Start With the Bottle, Not the Headline Price
A useful blow molding machine price starts with a defined bottle and a clearly itemized scope. If you have a drawing or sample, send it with the product data. A quotation based on the actual bottle is more useful than a general machine price.
Frequently Asked Questions
How much does a small extrusion blow molding machine cost?
For a small semi-automatic unit, use USD 9000 as the general budgeting reference. The semi automatic blow molding machine price should also state the date, trade term, bottle range, head quantity, and whether a mold or auxiliaries are included. Extra heads, trimming, voltage customization, or additional molds can move the project beyond the basic range.
Is a blow mold included in the machine price?
Sometimes, but many quotations list it separately. Confirm the number of mold sets, cavities, material, cooling, testing, and trimming structure. A standard double-station machine producing the same bottle on both sides normally needs two matching mold sets, so mold scope can create a large difference between two apparently similar offers.
Is an automatic machine much more expensive than a semi-automatic machine?
The automatic blow molding machine price is generally higher because the system can include take-out, deflashing, conveying, scrap handling, guarding, and additional controls. The size of the difference follows the automation scope. Compare it with production volume, labor cost, bottle shape, and the amount of manual work required.
Why are Chinese blow molding machine prices so different?
Suppliers may quote different screw sizes, plasticizing capacities, mold spaces, stations, heads, components, molds, auxiliaries, and automation. Trade terms and exclusions also change the total. Compare the technical specification and supply scope line by line rather than judging either the lowest or the highest figure alone.
Does a larger bottle always require a more expensive machine?
No. External dimensions, bottle weight, mold size, handle design, output, and cooling requirement matter alongside capacity. A wide container can need a larger platen, while a heavy bottle may need more plasticizing and die-head capacity. Price rises when these requirements change the machine structure, not according to liters alone.
How can I get an accurate blow molding machine price?
Send a product photo, drawing, or sample with the capacity, weight, dimensions, neck, handle, material, output target, and voltage. State the required automation and any existing auxiliaries. Request an itemized quotation separating the machine, molds, auxiliary equipment, automation, packing, delivery term, services, and exclusions.
