If you're forming oil filter shells and metal end caps in high volume, this machine handles 80 to 250 tons with a standard 6mm stroke and a working speed of 4 to 15 strokes per minute — basically, it's built for the job.

What it does is stretch the shell materail in a controlled way to improve durability while keeping tolerances tight enough for filter assembly, and most buyers go with the 150t model for typical production lines.


3, we use an internaional brand PLC on the control system, so you're not guessing with settings, and the dry pneumatic clutch is standard (wet clutch optional if you prefer), with oil bath gear lubrication to keep things running.

frame is steel welded high-intensity, and we include a hydraulic overload protector as a safety feature — it's honestly reliable for daily use, though we usually have stock but confirm lead time (usually 2-4 weeks).

Anyway, customiztion is avaliable for special requrement, and the manual height adjustment has a scale display, so you can dial in the tooling without much fuss.
MOQ for the 80t model is typically 1 unit. For the larger 250t model, we might ask for a slightly higher minimum depending on current stock levels.
Standard lead time is around 30-45 days. Adding a wet clutch might add about a week, depending on parts availability.
Yes, we can provide CE certification upon request. We also include a hydraulic overload protector test report with every machine.
We can customize the stroke length for special requirements, but the standard is 6mm. Just let us know the exact length you need, and we’ll adjust the design.
All models use oil bath gear lubrication, so it's pretty low-maintenance. For the 250t, just check the oil level every couple of months and change it annually.
