Detailed Information
What it does
TD-332 and TD-311 are the same machine under two model codes. In high-volume gas spring, gas lift and furniture tube production, loading and unloading tubes by hand takes the most labor. TD-332 links loading, closing and unloading into an automatic cycle; the operator only refills tubes and collects finished parts.

Why auto loading and unloading
- One operator can run several machines
- Consistent tube positioning for stable closing quality
- Stand-alone, or after cutting and grooving in a production line
Machine highlights
- Same closing head as the TD-31040; the auto feeder handles Ø15–28 mm tubes, other sizes on request
- Size change: swap the jaw set and guide tube and reset the feeder
- Dome radius adjustable without a mold change
- Fully closed or with a center hole
- PLC touch screen
TD-332 or a multi-station TD-31040?
For several tube sizes on one machine with manual loading, choose a two- or three-station TD-31040. For one size in high volume with less labor, choose the automatic TD-332.
