About Used Desktop & Benchtop Injection Molding Machines
Desktop injection molding machines (also called benchtop injection molding machines, tabletop injection molding machines, and desktop moulding machines) are compact, affordable plastic injection molding machines designed for prototyping, R&D, small production runs, educational use, and startup operations. These machines sit on a workbench or table and can produce small plastic parts with surprisingly high quality using standard injection molds.
Desktop plastic injection molding machines range from simple manual injection molding machines that use a hand lever to semi-automatic and fully automatic benchtop systems with electric or pneumatic power. Manual injection molding machines and manual injection machines are the most affordable entry point, while automatic desktop injection molding machines offer faster cycle times and better consistency. Home injection molding machines and hobby injection molding machines have become increasingly popular for makers, inventors, and small businesses.
Key specifications for desktop injection molding machines include shot size (typically 1-30 grams), clamp force (typically 1-15 tons), platen size, and heating capacity. Lab injection molding machines and tabletop injection molding machines are used extensively in universities and R&D facilities for material testing, prototype production, and process development.

Common Applications
Frequently Asked Questions
How much does a desktop injection molding machine cost?
Used desktop injection molding machine prices range from $2,000-$5,000 for simple manual machines to $10,000-$40,000 for semi-automatic and automatic benchtop injection molding machines. New desktop plastic injection molding machines start around $5,000 for manual units and $15,000-$50,000+ for automatic systems. Prices depend on features, capacity, and automation level.
What can you make with a benchtop injection molder?
A benchtop injection molding machine can produce small plastic parts including prototype components, custom connectors, small housings, knobs, buttons, chess pieces, custom keycaps, small toys, jewelry, and low-volume production parts. Shot size is typically limited to 1-30 grams, and parts must fit within the small platen size. Quality can match industrial machines for small parts.
Desktop vs industrial injection molding machine — which do I need?
Choose a desktop or benchtop injection molding machine if you need prototype quantities (1-1,000 parts), have a limited budget, need a small footprint, or are doing R&D. Choose an industrial machine if you need production volumes (10,000+ parts), larger parts, tighter tolerances, multi-cavity molds, or automated operation. Many businesses start with a desktop machine for prototyping and scale to industrial equipment for production.
Can I use a home injection molding machine for a small business?
Yes, many small businesses use desktop and home injection molding machines for low-volume production of custom parts. These home plastic molding machines can produce marketable products at quantities of 100-5,000 parts per run. However, for higher volumes or larger parts, an industrial small tonnage machine (25-100 tons) may be more cost-effective per part.
