Injection Unit parts diagram: 1 melting furnace, 2 shot sleeve, 3 plunger head, 4 plunger rod & linkage, 5 nozzle & gate, 6 ball bearing, 7 fastener set. 9 parts in 7 top-level items. — Injection Unit parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Melting Furnace	1×	Electric resistance or gas-heated chamber maintaining molten aluminum or zinc alloy at 650–750 °C.
2	Shot Sleeve	1×	Steel-lined cylinder sealed at one end, holding the injection charge of molten metal (100–500 cm³ typical).
3	Plunger Head	1×	Hardened steel piston accelerating the shot from rest to 2–10 m/s over 50–100 mm, imparting high injection velocity.
4	Plunger Rod & Linkage	1×	Connects the plunger to the injection actuator, typically a toggle linkage or hydraulic cylinder.
5	Nozzle & Gate	1×	Torpedo-shaped plunger tip with heated passages directing molten metal into the die sprue without turbulence.
6	Ball Bearing	2×	Deep-groove radial ball bearing.
7	Fastener Set	2×	Bolts, nuts, and washers.
