Injection Mold Maintenance: Making a Tool Last Ten Years
Most molds are ruined between runs, not in production. What actually wears out, the four maintenance cadences, water diagnostics and rust-free storage.

How to choose tooling for a small batch: aluminum versus steel versus 3D printing, where the cost crossover sits, and what each route cannot do.
How to approve a mold trial: which dimensions to judge, when to measure them, how to read the report, and when to stop a sign-off.
P20, 718H, S136 and H13 compared: hardness, polishability, corrosion resistance and shot life, plus how to match the steel to the resin and to each mold component.
How to vet a plastic injection molding supplier: the eight checks that predict performance, the questions that expose a reseller, and how to structure a first order safely.
Hot runner or cold runner? How each works, what each does to tool cost, cycle time and material waste, and how to decide from your resin and volume.
What a plastic injection mold actually costs and why quotes differ: the six cost factors, how cavity count changes the math, and how to read a quotation.
How plastic injection molding works: the five-stage cycle, mold construction, resin selection, design rules, defect fixes and what drives tooling cost and lead time.
Injection molds are classified by how they open, how they release undercuts and threads, and where the runner sits. Here are the eight types and what each one is used for.
