Hobby injection molding machines, also known as benchtop injectors, hold molds on a smaller scale.

Description

Benchtop injectors have become more common as inexpensive CNC milling machines have reduced the cost of producing molds in a home workshop.

In hobby injectors injection pressure is generated manually by the operator, with a lever or gear translating the operator's effort to the required pressure.

The most common hobby injection machine uses a handle to press down with. This enables the user to generate roughly 250 pounds-force (1.1 kN) of downward force, through the use of leverage.

Materials

Polyethylene (both LDPE and HDPE), polypropylene, and polystyrene (including HIPS) have all been used successfully with lever-actuated benchtop injectors.
