The price of desktop micro injection molding machines ranges from several thousand yuan to over a hundred thousand yuan, primarily depending on the clamping force, drive method, injection accuracy, and brand positioning.
As a common piece of equipment for laboratory R&D, small-batch production, and product prototyping, desktop mini injection molding machines are increasingly favored by small and medium-sized enterprises and R&D institutions due to their small size, small footprint, and low energy consumption. However, with numerous models and a wide price range on the market, many buyers are unsure how to choose.
This article, based on the latest market data from 2026, provides a detailed analysis of the price range and key points for selecting mini injection molding machines, helping you find the right equipment for your needs.
1. Desktop Injection Molding Machine Prices in Three Tiers
There is no unified “standard price” for desktop mini injection molding machines. The price difference essentially reflects variations in precision, stability, and automation level.
According to industrial-grade standards, the equipment on the market is mainly divided into three tiers:
【Tier 1】Entry-level Electric: 15,000 to 50,000 yuan Suitable for users with limited budgets and ordinary requirements for molding precision.

Suitable for use with 220V household power
Suitable for: Simple sample production workshops, startup pilot production teams, and university classroom demonstrations.
【Tier 2】All-Electric Precision Grade: 50,000-100,000 RMB
This is a well-balanced mainstream model on the market, suitable for most R&D laboratories and precision machining workshops.
Key Features:
True all-electric closed-loop drive, injection precision down to 0.1 gram level
Clamping force 5-15 tons, injection volume 10-30 grams
Multi-segment temperature control, multi-segment injection speed, and multi-segment pressure curve settings
Supports high-temperature engineering plastics such as PPS and PEEK
High repeatability, suitable for small-batch precision production
Price Distribution:
Basic model (around 5 tons): 50,000-60,000 RMB
Mainstream model (8-10 tons): 60,000-80,000 RMB
High-end model (15 tons): 80,000-100,000 RMB
Suitable for: Polymer material R&D laboratories, precision plastic part prototyping, material testing in research institutes, and precision small parts processing plants.
【Tier 3】High-end Micro-molding Grade: 100,000-200,000 RMB
Equipment in this tier performs comparable to industrial-grade micro-injection molding equipment and is primarily used in high-precision, high-standard applications.
Key Features:
Imported or high-end domestically produced all-electric system
Excellent injection precision and molding repeatability
Machine hardware adapted to cleanroom conditions
Can be equipped with robotic arms, automatic feeding, and inspection systems
With added accessories, unmanned small-batch production can be achieved
Suitable for: High-end processing fields such as medical consumables sample processing, optical plastic lenses, and microelectronic precision components.
2.Three Key Factors Determining the Price of a Mini Injection Molding Machine
- Drive Method
Manual/Electric → Lowest price, but poorer molding precision and repeatability
Electric/Servo → Mid-range mainstream, balances precision and operating speed
All-electric closed-loop → Higher cost, excellent molding precision, and excellent energy efficiency
In short: The drive method directly determines the lower and upper limits of the machine’s performance.
- Clamping Force and Injection Volume
The larger the tonnage and the larger the injection volume, the higher the material and structural costs of the machine. The purchase price of a 5-ton machine and a 15-ton machine can differ by a factor of two.
When purchasing, choose according to the size of your product; bigger isn’t always better—just choose what’s sufficient, as spending more is a waste.
- Service and After-Sales Support
Machine setup training, warranty period, and subsequent maintenance… these hidden costs often have a greater impact on the long-term user experience than the price difference of the machine itself.
Brands with after-sales support are more worthwhile than no-name brands that are thousands of yuan cheaper.
3.Selection Reference: TSW All-Electric Desktop Injection Molding Machine
If you are looking for a truly all-electric desktop injection molding machine with guaranteed molding precision and a reasonable price, consider our TSW-M series all-electric desktop injection molding machines.
The entire series uses all-electric closed-loop drive, covering clamping forces from 5 tons to 15 tons, suitable for product development, material testing, and small-batch precision production.
M05: Suitable for university teaching, material formulation testing, and ultra-small part prototyping; the machine has a compact footprint, weighs 180kg, facilitates workstation movement, and is an entry-level all-electric model.
M08: The main model for R&D prototyping, with a 20g injection volume and a 450℃ high temperature, suitable for most engineering plastics.
M15: Suitable for small-batch precision production; 15 tons clamping force + 160MPa injection pressure, performance close to industrial models, saving the purchase cost of large industrial injection molding equipment.
4. Frequently Asked Questions (FAQ)
Q: What is the smallest part that a desktop mini injection molding machine can produce?
A: The minimum molding size depends on the injection parameters and mold processing precision. Taking the TSW-M05 as an example, this machine has a rated injection volume of 10g and can stably process plastic parts weighing over 1g in daily large-batch production; with a high-precision mold, it can produce ultra-fine plastic parts with a net weight as low as 0.1g.
Q: What materials can a mini injection molding machine process?
A: General-purpose plastics (PP, PE, ABS) are generally fine. For engineering plastics (PC, PVC, POM), the material of the feed tube needs to be confirmed. High-temperature engineering plastics (PPS, PEEK, LCP) require high-temperature models above 400℃, such as the TSW-M08 and M15, which support 450℃.
Q: Does the purchase include installation and commissioning?
A: Reputable manufacturers generally include basic installation, commissioning, and operation training. Our TSW series offers installation and commissioning services, a one-year warranty, and lifetime technical support.
Q: Can ordinary 220V AC power power the equipment?
A: Most desktop mini injection molding machines support 220V single-phase power and do not require industrial three-phase power. The entire TSW series is 220V powered, so it can be used in ordinary laboratories and workshops simply by plugging it in.
Q: What is the difference between the all-electric and hydraulic models?
A: All-electric models offer higher molding precision, lower energy consumption, a cleaner machine body, and lower operating noise, making them suitable for laboratory and cleanroom environments. Hydraulic injection molding machines have a higher clamping tonnage limit and lower purchase costs, but they are prone to oil pollution and have higher operating noise, making them unsuitable for desktop research environments.
There’s no fixed “standard price” for desktop mini injection molding machines—every penny you spend buys you precision, stability, and automation. Before buying, think carefully about three questions: What materials will you be molding? What size parts will you be making? How much will you be producing per day?
