What is a parallel twin screw barrel?

It is a twin-bore barrel holding two constant-diameter intermeshing screws that run side by side. Unlike a conical barrel, the screws stay the same size end to end and the system is usually segmented, so the screw profile can be reconfigured for different formulations.

What is the difference between co-rotating and counter-rotating?

Co-rotating screws turn the same way and give high-shear mixing at high speed — ideal for compounding and masterbatch. Counter-rotating screws turn oppositely with gentler, pump-like conveying — better for PVC and heat-sensitive, high-filler work.

What is a segment (building-block) parallel twin screw barrel?

It is a modular design where the barrel is bolt-together sections and the screw is keyed elements on a shaft. You can position feed, mixing, vent and metering sections as the recipe needs, and replace only the worn segment instead of the whole screw.

Parallel or conical twin screw barrel — which do I need?

Choose conical for direct PVC pipe, profile, board and sheet extrusion. Choose parallel for granulation, compounding, masterbatch and very high-filler or glass-fibre dispersion, where reconfigurable mixing matters most.

What is a parallel twin screw barrel used for?

Mainly granulation and pelletizing, compounding and masterbatch, PS foaming, aluminum-plastic composite panel, rubber and plastic, and parallel-layout PVC lines. The tunable screw profile lets one machine handle many recipes.

Should a parallel barrel be nitrided or bimetallic?

Clean compounds can run nitrided. Abrasive recipes — high mineral filler, glass fibre, high carbonate — should be bimetallic; a tungsten-added alloy reaching 62 HRC resists that abrasion far longer than a thin nitrided case.

What is a parallel twin screw extruder?

It is the machine that houses a parallel twin screw and barrel, typically co-rotating for compounding and pelletizing. The barrel and screw are the wear heart of the machine and are matched to the extruder and the recipe.

How do I order the right parallel twin screw barrel?

Tell us co- or counter-rotating, your material and output, how abrasive the recipe is, and your extruder brand/model or a drawing. With those, we specify the segments, screw profile and surface treatment and quote within 12 hours.

Nīnau pinepine

He aha ka pahu māhoe māhoe like?

He pahu māhoe lua ia e paʻa ana i ʻelua wili waena mau anawaena e holo ʻaoʻao ana. 'A'ole like me ka pahu conical, noho like ka nui o ka wili a hiki i ka hopena a ho'oka'awale pinepine 'ia ka'ōnaehana, no laila hiki ke ho'onohonoho hou 'ia ke ki'i ki'i no nā hana like 'ole.

He aha ka ʻokoʻa ma waena o ka huli ʻana a me ka huli ʻana?

Huli like nā wiliwili hui like a hāʻawi i ka hui ʻana i ka ʻili kiʻekiʻe me ka wikiwiki kiʻekiʻe - kūpono no ka hui ʻana a me ka masterbatch. Huli kū'ē nā wili hoʻololi kūʻē me ka lawe ʻana i ka maʻalahi, e like me ka pahū - ʻoi aku ka maikaʻi no ka PVC a me ka hana wela, hoʻopiha piha.

He aha ka ʻāpana (papa hale) ʻano pahu māhoe māhoe?

He hoʻolālā modular kahi i hoʻopaʻa ʻia ai ka pahu i nā ʻāpana a ua kī ʻia ka wili i nā mea kī ma ke kumu. Hiki iā ʻoe ke hoʻonohonoho i nā ʻāpana hānai, hui ʻana, hoʻoheheʻe a me nā ʻāpana e like me ka mea e pono ai ka meaʻai, a hoʻololi wale i ka ʻāpana kahiko ma mua o ka wili holoʻokoʻa.

ʻO ka pahu māhoe māhoe like ʻole a i ʻole conical — ʻo wai kaʻu e pono ai?

E koho i conical no ka paipu PVC pololei, profile, papa a me ka extrusion pepa. E koho i ka like no ka granulation, compounding, masterbatch a me ka hoʻopuehu kiʻekiʻe kiʻekiʻe a i ʻole ke aniani-fiber dispersion, kahi i mea nui ai ka hui ʻana hou.

He aha ka pahu māhoe māhoe like?

ʻO ka nui o ka granulation a me ka pelletizing, ka hui ʻana a me ka masterbatch, PS foaming, alumini-plastic composite panel, rubber and plastic, a me nā laina PVC hoʻonohonoho like. Hāʻawi ka ʻaoʻao tunable screw i hoʻokahi mīkini e mālama i nā ʻano ʻano he nui.

Pono anei ka pahu like i ka nitrided a i ʻole bimetallic?

Hiki i nā mea hoʻohui maʻemaʻe ke holo i ka nitrided. ʻO nā meaʻai abrasive - hoʻopiha mineral kiʻekiʻe, fiber aniani, carbonate kiʻekiʻe - pono ka bimetallic; ʻO kahi huila tungsten i hoʻohui ʻia a hiki i 62 HRC ke kūʻē i kēlā abrasion ʻoi aku ka lōʻihi ma mua o kahi pahu nitrided lahilahi.

He aha ka mea extruder māhoe māhoe like?

ʻO ia ka mīkini e hoʻopaʻa ai i ka māhoe māhoe a me ka barela, e hoʻololi pinepine ʻia no ka hui ʻana a me ka pelletizing. ʻO ka pahu a me ka wili ka puʻuwai o ka mīkini a hoʻohālikelike ʻia me ka extruder a me ka meaʻai.

Pehea wau e kauoha ai i ka pahu māhoe māhoe like ʻole?

E haʻi mai iā mākou i ka hui pū ʻana a i ʻole ka hoʻololi ʻana, i kāu mea a me nā mea hoʻopuka, pehea ka abrasive o ka meaʻai, a me kāu hōʻailona extruder/model a i ʻole kahi kiʻi.
