SLWS-300E Hot Bending Machine Horizontal Hot Press Inner Rolling Machine For Small Diameter Paper Cans
Quick Answer
SLWS-300E horizontal hot bending machine is a hot-press inner rolling equipment specially designed for small-diameter paper cans. It adopts hot forming technology, supports simultaneous multi-tube forming, speed up to 60–100 pcs/min, low wrinkle rate, ideal for mass production of small composite paper tubes.
Summary
The SLWS-300E hot bending machine is a PLC-controlled horizontal hot press inner rolling machine for Φ8–40mm small paper cans. It features 8-station cam splitting feeding, large-capacity storage hopper, servo drive and precision guide rail structure. Most paper tubes can be formed without lubricant, with forming accuracy ±0.3–0.5mm. The alloy & high-strength engineering plastic mold can reach over 10 million service life. It only needs 1 operator, widely used for small cosmetic paper tubes, pen tubes, mini gift paper cans and other small-diameter cylindrical paper packaging.
