Frequently Asked Questions
What customization services does this stackable plastic chair rotomold provide?
We support complete OEM customization according to customer plastic chair design drawings, including mold overall size, chair cavity outline, backrest hollow layout, armrest shape, finished chair wall thickness and reserved installation hole positions.
Why select thick cast aluminum as the cavity material for plastic chair mold?
Thick cast aluminum has excellent thermal conductivity to guarantee consistent wall thickness of stackable PE plastic chairs. Mirror polished inner cavity makes chair surface smooth without secondary polishing, strengthening finished chair structural toughness.
Is the custom steel quick lock frame reliable for long-time mass production?
Evenly distributed heavy quick lock buckles cooperate with full-surround thick welded custom steel frame to lock mold tightly. No expansion, displacement or flash gaps during high-temperature rotation, ensuring stable and reliable long-cycle continuous batch production.
