Manufacturing process
- Procure and store raw materials in inventory according to production demand.
- Mix polypropylene granules with color pigments, stabilizers, and additives in the mixer.
- Feed the mixed plastic blend into the injection moulding machine to produce plastic parts such as the base, outer wall, grip handle ring, lid top, and lid base.
- Shear circular plates out of SS sheets using a blanking press and draw them into metal pots using a deep drawing hydraulic press.
- Place the metal pot base into the PUF mold, pour measured PUF liquid, place plastic accessory walls quickly, and close the mold.
- Cure the assembly in an oven maintained at 45 to 60 degrees Celsius for foam expansion, then extract the case roll pot.
- Perform a similar foaming and curing process for the case roll lid using a separate PUF mold.
- Inspect finished case roll pots and lids manually, assemble them, and send for packaging and sale.
