An injection molding machine (also spelled as injection moulding machine in British English), also known as an injection press, is a machine for manufacturing plastic products by the injection molding process. It consists of two main parts, an injection unit and a clamping unit. See Injection Molding Machine and Hobby Injection Molding on Wikipedia.

Maintenance

Greasing Grease Fittings

For your convenience, here's what it says about greasing the grease fittings: "The machine requires very little in the way of lubrication, as the injection plate and thrust housing bushings are a composite semi-greaseless type that require lubrication once every 6 months to a year. The thrust housing has two linear bushings; one accessible from the front, one from the rear. The injection cylinder plate also has two bushings with staggered access. Use a lithium-based grease and inject only enough grease to force the old grease out. This removes any dirt accumulated in the bushings. Wipe the old grease off of the guide rods."
