Na mba ofesi, ntụgharị ntụgharị abụrụla otu n'ime usoro ịkpụzi rọba a na-ejikarị eme ihe. N'afọ ndị 1940, a na-eji tapawa PVC mepụta ihe ụmụaka ji egwuri egwu dị ka bọọlụ rọba site na ịkpụzi ntụgharị. Na 1950s, polyethylene rotational molding usoro na-eji obere njupụta polyethylene ntụ ntụ resin dị ka akụrụngwa e mepụtara na-emepụta ụlọ ọrụ mmepụta ihe dị ka polyethylene nchekwa tankị na nnukwu ọkpọkọ, nke ukwuu kwalite mmepe nke rotational ịkpụzi usoro. Kemgbe ahụ, naịlọn, polycarbonate, ABS na plastik ndị ọzọ ka ejirila usoro ịkpụzigharị ntụgharị. Ka ọ na-erule mmalite 1970s, ịkpụzigharị ntụgharị abụrụla usoro ịkpụzi rọba buru ibu.
Na 1971, e nwere ihe karịrị ụlọ ọrụ 50 na-etinye aka na mmepụta nke ngwaahịa ịkpụzigharị na UK, na ihe dị ka ndị na-emepụta 70 na-emepụta thermoplastics rotational molding; Enwere ihe karịrị ụlọ ọrụ 20 na-arụ ọrụ na-agbanwe agbanwe na mpaghara Europe, gụnyere ụlọ ọrụ si Germany, France, Switzerland, Norway, Austria, Denmark na mba ndị ọzọ.
Na mmalite 1970s, UK nwere ike ịnye igwe na-akpụzi mpịakọta nke nwere ike ịmepụta arịa nwere ikike nke 18000L; Netherlands ewepụtala nnukwu tankị cylindrical nke nwere dayameta nke 2.1m na ogologo 4.8m. The tank bụ 540kg na mgbidi ọkpụrụkpụ bụ 25mm. Na 1970, ngụkọta olu nke rotational ịkpụzi ngwaahịa na Europe ruru ihe karịrị 15000t, gụnyere banyere 7000t na Britain.
Na 1970, ihe karịrị 500 nkeji na United States nọ na-arụ ọrụ na mmepụta nke rotational ịkpụzi ngwaahịa. Ha nwere ihe karịrị narị iseigwe na-akpụzi mgbanwe, na ike nke ntughari ịkpụzi akpa agafeela 10000 L (2400 galọn); Akụkụ plastik kachasị elu nke igwe na-akpụzi mpịakọta na-emepụta bụ 4.6× isi anọ× 2.1m.
N'afọ ndị 1960, mmepe ngwa ngwa nke teknụzụ ntụgharị ntụgharị nwere njikọ chiri anya na nkwalite akụrụngwa resin na akụrụngwa ngbanwe. N'ime oge a, e mepụtara ọtụtụ plastik pụrụ iche maka ịkpụzi ntụgharị, dị ka PE P-320, Raychem Flamolin 771 na resins polyethylene ndị ọzọ nke United Carburization Company mepụtara.

Na mgbakwunye na ịbụ njikọ obe, ọ nwekwara ihe na-emenyụ onwe ya. Mpịakọta a ma ama na-akpụzi njikọ polyethylene resin Marlex Cl-100 nke Philips bụkwa nke emepụtara n'oge a.
Iji gboo mkpa nke ịkwadebe nnukwumgbanwe ịkpụzi ngwaahịa, ọtụtụ igwe ike nke akpụ nnukwu rotational ịkpụzi ngwaahịa e mepụtara na mbubreyo 1960, nke nwere ike n'ụzọ dị irè na-eji n'ala ohere na okpomọkụ ike. N'afọ 1970, ihe karịrị ọkara nke igwe na-akpụzi mpịakọta a na-ere n'ahịa nwere dayameta rotary nke karịrị 1.75m. Tụkwasị na nke ahụ, a na-emeziwanye ọkwa nchịkwa nke igwe na ọkwa dị iche iche. Dị ka ihe atụ, atọ ogwe aka rotational ịkpụzi igwe McNeil Auronismodel 3000-200 nwere ike ijikwa kpo oku na jụrụ cycles nke ọ bụla ogwe aka iche iche, nke mere na ngwaahịa nke dị iche iche nha na ihe nwere ike n'out oge rotational kpụrụ.
