Plastic bucket making machine cost ranges from $30,000 to $50,000+ for the injection molding machine alone, depending on tonnage, brand, and bucket size. Smaller buckets (e.g., 5L) require 200-ton to 400-ton machines, while 5-gallon or 20L buckets need 500-ton to 800-ton machines.
HAICHEN Plastic Bucket Production Line – Cost Overview (USD)
| Item | Price Range | Notes |
|---|---|---|
| Injection Molding Machine (HAICHEN HCK Series) | $30,000 – $50,000+ | HCK270 (270T) ~$30,000; HCK410 (410T) ~$50,000. Higher tonnage (600T+) requires a custom quote. |
| Bucket Mold (with lid) | $5,500 – $11,000 | Example: 20L mold ~$5,500; 10L mold set (body+lid) ~$11,000. Depends on size, cavities, and runner type. |
| Auxiliary Equipment (dryer, loader, chiller, granulator, robot, etc.) | $10,000 – $25,000 | Typically 15–30% of machine cost. A basic 20L line adds about $8,000, but general range is $10k–$25k. |
| Optional Printing Machine (heat transfer, for on‑pail logos) | ~$8,500 | Only if you need direct printing on buckets. |
| Installation, Commissioning & Training | Included | Free of charge with the machine purchase. |
| International Shipping (ocean freight, customs, inland) | Extra | Varies by destination; not included in above prices. |
Plastic buckets and water pails are everywhere — from small buckets plastic like 4L household pails to large plastic buckets such as 20L drinking water containers and even 100L+ industrial water tanks.
Yet choosing the right plastic bucket manufacturing machine goes far beyond comparing price tags. Tonnage selection, auxiliary equipment, mold investment, and energy efficiency all directly determine your upfront capital and long‑term operating costs.
As a direct plastic bucket injection moulding machine manufacturer, HAICHEN helps you understand the real numbers behind producing plastic buckets, 5 gallon plastic buckets, square plastic buckets, and colored buckets plastic.

Factors to consider when selecting tonnage
Locking tonnage — measured in US tons — is the clamping force that keeps the mold closed during injection. For producing any plastic bucket with lid or without, the rule is simple: the larger the bucket’s projected surface area, the higher the tonnage required to prevent flash and ensure consistent wall thickness. For most plastic buckets (HDPE or PP), the recommended tonnage per square centimeter is roughly 0.4–0.6 tons.
Plastic bucket capacity to tonnage reference chart
Based on HAICHEN’s real production data and the HAICHEN HCK Series servo injection molding machines, here is the direct mapping from bucket size to recommended machine model:
| Plastic Bucket / Pail Size | Recommended HAICHEN Model | Locking Tonnage | Cavity Count |
|---|---|---|---|
| 4L small household bucket | HCK270 | 270T | 1 |
| 4L paint pail (2 cavities) | HCK410 | 410T | 2 |
| 8L medium household pail | HCK310 | 310T | 1 |
| 10L household water bucket | HCK360 | 360T | 1 |
| 20L large water bucket | HCK410 | 410T | 1 |
| 100L+ industrial water tank | HCK800 | 800T | 1 |
This selection covers common needs: from 1 gallon plastic buckets (≈4L), 2 gallon plastic buckets (≈8L), 5 gallon plastic buckets (≈20L), up to 10 gallon plastic pail and larger industrial containers.
Consequences of tonnage mismatch
Using a machine with insufficient tonnage — for example, producing 5 gallon plastic buckets on a 200T machine — causes mold flash, inconsistent wall thickness, and premature mold damage. Oversizing your machine wastes upfront capital and increases daily electricity consumption unnecessarily.

Mold investment for plastic buckets with lid
Mold cost is often underestimated. Here is a real HAICHEN customer example — a complete mold set for a 10L household plastic bucket with lid:
| Mold Component | Runner Type | Steel Type | Mold Size | Price |
|---|---|---|---|---|
| Bucket body mold | Cold runner | 718 steel | 550*550*600mm | Included |
| Bucket lid mold | Hot runner | 718 steel | 480*480*380mm | Included |
| Total for both molds | — | — | — | $11,000 USD |
718 steel offers excellent durability. Hot runner systems speed up cycle times but cost more; cold runner systems are budget‑friendly for medium‑volume runs of plastic buckets with handle or plain designs.
Auxiliary equipment you cannot overlook
A complete plastic bucket production line needs more than just the injection molding machine and mold. Auxiliary equipment typically adds 15–30% to your total machine cost. Essential items: material dryer, auto loader, mold temperature controller, chiller, granulator, and a robot/conveyor for automated removal of plastic pails.
Installation, commissioning, and training
HAICHEN includes installation support and operator training in the machine price. An experienced engineer will assist with on‑site setup, ensuring you can produce high‑quality plastic pails with lids from day one. International shipping costs (ocean freight, customs, inland transport) are separate.
Why HAICHEN HCK Series Servo Machines Make Financial Sense for Plastic Bucket Manufacturers
- Servo Energy Saving Principle
- Real‑World Energy Saving Example
- Low Noise and Longer Equipment Life
Servo energy saving principle
Traditional hydraulic injection molding machines keep the oil pump motor running continuously — even during idle periods like cooling and mold opening. This wastes electricity. In contrast, a HAICHEN servo‑driven plastic bucket moulding machine only consumes power when performing an action: injecting, metering, ejecting, or mold opening. During cooling or idle time, the servo motor completely stops.
Real‑world energy saving example
Consider a machine with a 64cc oil pump at 175 bar. Output power is ~28 kW. At 50% system pressure and melt speed, a HAICHEN servo plastic bucket manufacturing machine drops to just 7 kW — a 75% power saving. For producing plastic drink buckets or 2 gallon plastic buckets with lids (long cooling phases), the savings are even higher. Industry data shows 20–80% energy reduction compared to conventional hydraulics.
Low noise and longer equipment life
HAICHEN servo machines operate with significantly lower noise — the pump runs only when needed. Lower hydraulic oil temperature means less wear on components and reduced cooling water consumption, especially important in hot climates producing mini plastic buckets or square plastic buckets.

| Auxiliary equipment (dryer + chiller + auto loader) | ~$8,000 |
| Total initial investment | ~$63,500 |
Installation, commissioning, and operator training are included at no additional cost.
Simplified ROI calculation (electricity savings)
Based on 64cc pump, 50% pressure, 40‑sec cycle:
| Operating Cost Comparison | Conventional Hydraulic | HAICHEN HCK410 Servo |
|---|---|---|
| Hourly power consumption | ~28 kWh | ~7 kWh |
| Daily power consumption (20h) | 560 kWh | 140 kWh |
| Daily electricity cost (@ $0.12/kWh) | $67.20 | $16.80 |
| Monthly electricity cost (26 days) | $1,747.20 | $436.80 |
| Monthly electricity savings | — | $1,310.40 |
| Annual electricity savings | — | $15,724.80 |
Simple payback period: The servo premium (~$15,000) pays back in roughly one year via electricity savings alone.
