The model #70 Mini-Jector answers a long-standing need for a precision insert molding machine that is both compact and user friendly. A vertical down acting 10 ton clamp with a vertical injection unit permits the use of conventional molds with a center sprue bushing as used in horizontal machines. This configuration also allows for the use of hot runner molds.
The machine has a formica top level with the clamp that allows the machine operator space to place inserts or tools adjacent to the work area. The machine is designed with a "sit-down" type stand that is very similar to a desk for maximum operator comfort.
The compact design (12 square feet of floor space required) allows the placement of the machine near assembly areas to avoid having to 'batch mold" the parts. The machine can be integrated into a product assembly line .
The machine is offered in two injection capacities. The option of either a one or two ounce capacity injection unit permits molding either small delicate parts or fairly large connectors or plugs. The machine can be built as a single station unit or with an in-out single station shuttle table for loading convenience.
