Pamadigiri 170 zomatirazo zimasonyeza kulemera kwa{{10}body 11 000-17 000 cps melt index, kusasinthasintha komwe kumapangitsa kuti glue gun ikhazikike, osasunthika{11}pamtunda wa U{12}}channel kapena milomo yozungulira; mkandawu nthawi yomweyo umagwira-tayamba kale diski kapena pad yodula, ndikuyikoka ndi furemu kwinaku ndikudzaza timipata tating'ono tomwe tingayambitse kulambalala. Ngakhale kukhuthala kwake, kukameta ubweya-kuwonda chifukwa cha mphamvu ya mpope, kumadya bwino pogwiritsa ntchito 0.8-1.2 mm nozzles pa semi-matebulo odziwikiratu kapena makina ozungulira omwe amayendetsa magawo 100–300 pa mphindi imodzi. Nthawi yotseguka ya 4-10 s imapatsa ogwiritsa ntchito zenera lokwanira kuti agwirizanitse paketi yomangayo isanatseke, pambuyo pake olowa amapeza mphamvu yogwira mkati mwa 15 s ndikulumikizana kwathunthu mkati mwa mphindi zisanu, kotero kuti mafelemu amatha kusuntha nthawi yomweyo kupita kumalo ochitira msonkhano wotsatira popanda zomangira. Filimu yomwe yachiritsidwa imakhala yosinthika kuchoka pa -20 digiri kufika ku +65 digiri , imakoka kugwedezeka kuchokera ku injini zowulutsira ndi kuyendetsa njinga zamoto pamayunitsi a HVAC padenga popanda kusweka kapena kung'ambika. Kafungo kamakhala kochepa, mpweya wa VOC ndi wochepera 150 µg g⁻¹, ndipo mpangidwewo ulibe zosungunulira, formaldehyde, heavy metals ndi zoletsa moto wa halogenated, mogwirizana ndi RoHS, REACH ndi FDA 21 CFR 175.105 chakudya chosalunjika{34}}malamulo olumikizana nawo.
