How Much Does a Plastic Chair Molding Machine Cost?
Plastic chair production typically requires injection molding machines ranging from 350 tons to 2,000 tons of clamping force, with the most commonly used models falling between 550 and 1,200 tons. The exact size depends on the chair design, material thickness, mold size, and production efficiency requirements. In general, a brand-new plastic chair molding machine costs around $35,000 to $380,000 or more, depending on factors such as brand reputation, machine configuration, automation level, and whether the system is hydraulic, servo-hydraulic, or fully electric.
For buyers with a limited budget, second-hand machines are also an option and typically range from $15,000 to $150,000, depending on the age of the machine, operating hours, maintenance condition, and original manufacturer. However, used equipment may involve higher maintenance costs and shorter service life. It is also important to note that machine cost does not include the mold, which is a separate expense and can cost from several thousand to tens of thousands of dollars depending on complexity. Therefore, when planning to start plastic chair production, both machine investment and tooling costs should be considered together for accurate budgeting.

What Are the Factors That Affect the Price of Plastic Chair Molding Machines?
The price of a plastic chair molding machine can vary widely depending on several technical and commercial factors. Understanding these factors helps buyers choose the right machine based on budget, production goals, and long-term operating costs.
1. Machine Tonnage (Clamping Force)
Larger chairs and heavier molds require machines with higher clamping force. As tonnage increases, the machine structure becomes stronger and larger, which significantly increases the price.
2. Machine Type
Hydraulic machines are usually the most affordable.
Servo energy-saving machines offer better efficiency and stability at a higher cost.
Fully electric machines are the most expensive but provide the highest precision and energy efficiency.
3. Automation Level
Basic machines require manual operation. Adding robotic arms, conveyors, or automatic unloading systems increases the price but improves productivity and reduces labor costs.
4. Injection System Specifications
Machines with larger injection capacity or faster injection systems cost more. High-speed injection systems are often required for thick or reinforced plastic chairs.
5. Control System
Different control brands and software systems affect price. High-end controllers provide better accuracy, safety features, and easier operation but increase the cost.
6. Brand and Manufacturing Quality
Well-known brands with a reputation for reliability and service typically charge more. Lower-cost manufacturers may reduce upfront investment but may have higher long-term maintenance costs.
7. Optional Equipment
Additional equipment such as hopper dryers, chillers, mold temperature controllers, and material loaders increase the final purchase price.
8. After-Sales Service and Warranty
Machines with strong technical support, training, warranty coverage, and spare parts availability usually cost more but offer better long-term reliability.
9. Shipping and Import Fees
Large machines require special packaging and transportation. Import taxes, shipping, and installation fees can also significantly affect the final cost.
How to Buy a Cost-Effective Plastic Chair Molding Machine?
1. Define Your Needs First
-
Estimate the type of chairs you will make (kids chairs, standard adult chairs, heavy-duty outdoor chairs, etc.).
-
Estimate annual production volume and required cycle time (low volume vs. mass production).
-
Based on these, determine the clamping force (tonnage) and shot size needed. Too small → can't mold reliably; too big → unnecessary expense.
2. Match Machine Type to Your Use Case
-
For small runs or simple chairs → a mid-range hydraulic or servo-hydraulic machine may suffice.
-
For higher precision, better efficiency, and long-term energy savings → consider servo-electric or hybrid machines (even if upfront cost is higher).
-
Avoid overspending on a machine whose capacity significantly exceeds your actual needs — that inflates cost without benefit.
3. Evaluate Automation Level Wisely
If you plan manual or small-scale production, a basic machine may be enough. But if you expect medium-to-large volume, choose a machine with automation-friendly features: e.g. compatibility for robotic part removal, conveyors, or automated unloading. That reduces labor cost and increases consistency over time.
4. Consider Long-Term Operating Cost, Not Just Purchase Price
A “cheap” machine might have high energy consumption or maintenance needs. Machines with better energy efficiency (e.g. servo or electric type) can substantially lower long-term operating costs, making them more cost-effective over their lifespan.
Also ensure spare parts availability and a maintenance-friendly design to reduce downtime and repair costs.
5. Choose a Supplier with Good After-Sales Support & Spare Parts Availability
A reliable supplier that offers responsive technical support, warranty, and spare parts availability can save you time and money in the long run. Machine downtime or difficulty finding parts can wipe out any savings from a low initial cost.
6. Balance Initial Cost, Tooling Cost, and Overall Investment
Remember the molding machine is only half of the investment. The mold/tool cost, material costs, labor/operation cost, and maintenance also add up. Evaluate the total cost of ownership (TCO) — not just the sticker price. For example, properly sized machine + appropriate mold + efficient operation = far better ROI than overspending on a huge machine or underspec’d mold.
7. If Budget Is Tight — Consider Used or Medium-Toned Equipment (But Vet Carefully)
Used or refurbished machines may offer lower upfront cost. If you go this route, carefully check: condition, maintenance history, spare parts availability, and machine capabilities (clamping force, shot size, control system). This can be a cost-effective entry strategy if you have moderate production needs and skilled operators.

FAQs About Plastic Chair Molding Machine Prices
Q: Why is there such a wide price range for plastic chair molding machines?
A: The wide range comes from differences in machine size (clamping force/tonnage), processing capacity, automation level, and the design requirements of the chairs you plan to produce. Smaller tonnage machines for lightweight chairs are cheaper; machines capable of molding large or heavy-duty chairs require more robust frames and stronger injection systems, which increases cost.
Q: What tonnage range do most plastic-chair molding machines fall into?
A: For plastic chairs, machines typically range from a few hundred tons up to 1,400–2,000+ tons, depending on the chair design and size (e.g. simple stools, standard chairs, heavy-duty or outdoor chairs).
Q: Do more expensive machines always mean better quality chairs?
A: More expensive machines often offer stronger clamping force, higher injection capacity, better stability, and sometimes higher automation — which helps especially for larger or more complex chair molds. However, for simpler chairs or small production runs, a mid-range machine may be sufficient. The key is matching machine specification to your product and production needs.
Q: Does the quoted price include the mold (tooling) cost for chairs?
A: Usually not — the machine price only covers the injection molding machine itself. The mold (tooling) cost is separate, and for plastic chairs a mold can be a significant additional investment.
Q: What additional investments should be considered beyond just the machine and mold?
A: Other costs include material feeding systems, auxiliary equipment (like dryers, chillers), possibly automation (robotic arms, conveyors), shipping, installation, and ongoing maintenance. These auxiliary parts and logistics can add substantially to the total project cost.
Q: Is it cheaper to buy a used molding machine instead of a new one?
A: Yes — used or refurbished machines can offer lower upfront cost. However, used machines may have shorter remaining lifespan, higher maintenance needs, and possibly outdated technology; it's important to carefully check machine history, condition, and compatibility with molds and materials before buying.
Q: For a small or new workshop, is it necessary to buy a high-tonnage, high-end machine?
A: Not necessarily. If you plan to produce small or lightweight chairs, or only expect low-to-moderate production volume, a mid-range machine (with moderate tonnage and basic configuration) may suffice and is more cost-effective. The higher-tonnage, high-end machines are more justified when you need to mold large, thick, heavy chairs or aim for high production throughput.
Q: What’s the realistic budget range for a new plastic chair molding machine (as of 2025)?
A: Depending on tonnage and configuration, new machines suitable for plastic chair molding tend to cost from tens of thousands to several hundreds of thousands of US dollars (or equivalent). For modest-to-middle specifications, prices will be lower; for heavy-duty, high-capacity machines, costs are higher.
Summary
Plastic chair molding machines in 2025 range from $35,000 to over $380,000. The most cost-effective choice for most factories is a 550–850 ton high-speed servo machine from a leading Chinese manufacturer like Sunbun.
