This guide offers a comprehensive look at the world of injection molding for sale, including machinery, molds, and services. We’ll cover where to find injection molding equipment for sale, how to assess the condition and value of used injection molding machines, considerations for buying new vs. used, and how to evaluate custom molding services that offer full solutions.
Injection Molding for Sale: Understanding the Basics
Injection molding is a manufacturing process used to produce parts by injecting molten material into a mold. Plastic injection molding is a key manufacturing process for creating high-quality, repeatable plastic parts. The injection molding process is widely used for producing plastic parts in high volumes, offering consistency, tight tolerances, and efficient cycle times. The process includes:
- Melting plastic resin
- Injecting the molten material into a steel or aluminum mold
- Cooling and solidifying the part
- Ejecting the final product
To execute this process, several critical components are needed:
- Plastic injection molding machine
- Injection mold (tooling)
- Material (usually thermoplastics)
- Ancillary equipment (dryers, chillers, mold temperature controllers)
Finding the right equipment, especially a suitable plastic injection molding machine, can be challenging due to high demand and ongoing supply chain issues.
When looking at injection molding for sale, buyers typically seek one or more of these components.
Injection Molding Machines for Sale
The core of any injection molding operation is the injection molding machine, which performs the heating, injecting, holding, and clamping of molds. Sellers often maintain an extensive inventory of machines, giving buyers a wide selection to choose from. Selecting the right machine involves considering clamping force, shot size, and available options to ensure it matches your production needs. Machines come in different sizes, configurations, and tonnage ratings.
The clamping force, or maximum force the machine can exert, is a key specification that ensures proper mold closing and process integrity. Each kind of injection molding machine offers unique advantages depending on your materials and processing requirements.

New vs. Used Injection Molding Machines
Buying a used injection molding machine can significantly reduce capital investment, but it comes with additional risk and inspection requirements. It is crucial to evaluate the condition of the used machine, as factors like usage hours and overall state can greatly impact its value and performance.
When considering a purchase, buyers should set clear criteria for selection to ensure the equipment meets their needs. It is also important to understand both the technical and business requirements before making a decision. In some cases, costs can vary widely depending on the machine’s age, brand, and condition.
Purchasing used machines can save money not only on procurement but also on training, especially if your existing employees are already familiar with similar equipment. Always keep in mind your financial goals and establish a budget accordingly.
Benefits of Buying New:
- Latest technology and energy efficiency

- Custom configurations
- Longer expected lifespan
Benefits of Buying Used:
- 30–70% cheaper than new
- Immediate availability—buyers can quickly receive used machines and start production sooner
- Lower upfront cost
- Reputable sellers provide support and guidance during the purchasing process
Considerations When Buying Used:
- Machine age and operating hours
- Service and maintenance history
- Availability of replacement parts
- Inspection of wear components (screw, barrel, platens)
- Compatibility with molds and tooling
Price Range:
| Machine Size (Tonnage) | New Machine Cost | Used Machine Cost |
|---|---|---|
| 50–150 tons | $25,000–$60,000 | $5,000–$30,000 |
| 150–300 tons | $60,000–$120,000 | $20,000–$70,000 |
| 300+ tons | $120,000+ | $40,000+ |
Keep in mind that shipping costs can significantly impact the total price, depending on your location and logistics. Machines with higher pressure capabilities may also command higher prices.
When searching for injection molding machines for sale, clearly define your tonnage, shot size, and product requirements.
