What is a conical twin screw barrel?

It is the plasticizing unit of a conical twin screw extruder: a barrel with two overlapping tapered bores holding two tapered screws. The screws are wide at the feed end and narrow toward the die, and that taper produces gradual compression, gentle shearing, and strong conveying.

How does a conical twin screw barrel work?

Material enters the wide feed end, where the large intake suits bulky powder. The intermeshing screws convey it forward mechanically, and as the bore narrows the material is compressed steadily, with air squeezed out and density rising. Heated zones fuse it into a uniform melt, volatiles are vented off, and the narrow discharge end builds the pressure the die needs.

What do the two numbers in a conical screw size mean?

The smaller number is the diameter at the discharge end, and the larger number is the diameter at the feed end. A 55/110 screw measures 55 mm at the tip and 110 mm at the intake. Always give both numbers when requesting a quote, because sizes such as 65/120 and 65/132 share a first number but are not interchangeable.

Why are conical twin screws used for PVC?

Rigid PVC is sensitive to both shear and temperature, and it arrives as a bulky dry blend powder. The conical design answers all three problems at once: a large feed end swallows the powder, gradual compression works the material steadily instead of squeezing it hard in one zone, and gentle shearing keeps it from degrading.

What is the difference between conical and parallel twin screws?

A conical twin screw tapers from a wide feed end to a narrow discharge end, giving gradual compression and gentle shear, which suits rigid PVC pipe, profile, and sheet. A parallel twin screw holds a constant diameter throughout, which suits compounding, masterbatch, and high-output pelletizing where adjustable shear matters more.

What is the difference between intermeshing and non-intermeshing conical screws?

Intermeshing screws engage each other, so the flight of one reaches into the channel of the other. That creates closed chambers, positive conveying, and thorough mixing, and the screws wipe each other clean. Non-intermeshing screws sit side by side without engaging, giving lower shear and less positive conveying for material that cannot tolerate much working.

What products are made with conical twin screw extruders?

Four families: profiles, sheets, pipes, and custom-shaped profiles. In practice that covers PVC foam and decorative board, PVC-U water and drainage pipe, conduit, door and window profiles, ceiling panels, cable trays, hoses and sealing strips, wood-plastic composite flooring and railings, filled PVC sheet, ABS decorative strips, and PE/PVC composite pipe.

Do conical twin screws have to be replaced as a pair?

Yes. The clearance between the two screws is set during manufacture and cannot be recovered by fitting one new screw against a worn partner. Conical twin screws are produced, supplied, and replaced as a matched pair, and they should be stored and handled that way too.

Vim Li Cas Taper Matters: Peb Qhov Zoo

Lub taper tsis yog kev xaiv styling. Nws ua rau peb lub tshuab ua haujlwm ib zaug, thiab ua ke lawv txhais tau tias lub tshuab no zoo li cas.

1. Ib qho kev noj ntau rau cov hmoov uas tsis tshua muaj zog

Rigid PVC yog ua tiav raws li kev sib xyaw qhuav: resin hmoov ntxiv rau stabilizer, lubricant, muab tub lim, thiab xim. Qhov sib tov yog fluffy thiab tag nrho ntawm huab cua, yog li nws xav tau ntim ua ntej nws xav tau dab tsi ntxiv.

Qhov dav pub kawg muab rau nws qhov ntim. Ib lub taub hau ntawm qhov tsis tu ncua yuav tsum loj raws nws qhov ntev kom nqos tau tib yam, uas ua rau muaj teeb meem ntawm nws tus kheej ntawm qhov kev tso tawm.
