The Spike Factory slowly generates spikes around its range, which build up its damage to bloons. It is mainly designed to protect exits, and has a few upgrades that allow Spike Factory to act as a DPS option. Its lower tiers are decent, and its higher-tiers can greatly assist cleanup and general damage depending on upgrades.
The base Spike Factory can be used to tank small amounts of Bloons, including early Camo Bloons. Ideally, place it near an exit so it has time to generate spikes.

Spiked Balls is valuable in the mid-game to tank small amounts of bloons, yet still retains value in the late-game to handle Super Ceramics.
Spiked Mines handles large groups of bloons effectively.
Super Mines is very expensive but does enormous damage to all bloons with its explosions and napalm. It can be used both as a DPS option and tanking bloons near the exit.

Like Perma-Spike, Mega Massive Munitions Factory prefers stockpiling giant mines near the back, rather than near bloons. As it lacks any targeting options to adjust locations for the spikes, always place it with barely enough range to reach the track.
It stands out hugely in Timed Bosses. Unlike Perma-Spike, the MMMF bypasses the anti-cheese mechanic of Bosses removing projectiles upon spawning; each giant mine explodes into spike piles that can still damage the boss.

All Bosses
Spike Factories in general are most often used for Spike Storm to damage the Boss. It can also be useful to tank Camos in the early-game, though on longer maps it's not very efficient on Boss Events due to the time penalty.
Spike Factories, especially Spike Storm, remain an excellent option for all stages, handling Lych and its Lych-Soul and Resurrected Blimps efficiently. Time well, as Lych has forced etherealization.
