There are four main process is well known in plastic industries.
Extrusions moulding, Blow Moulding, Injection Moulding, Rotational Moulding. Rotational Moulding Process is mostly used in manufacturing large hollow plastic products due to its less cost of machine mould & processing charge instead of other plastic process like injection moulding. Rotational moulding process is mostly used of manufacturing under mantioned product is verious industry.
- Open Fired Rock & Roll Machine
- Close oven Rock & Roll Machine
- Bi Axial Roto Moulding Machine Three Arm
- Bi Axial Roto Moulding Machine Four Arm
Manufacturer can select machine from above model according to products size & their product as per production required per day & per annum.
Rotomoulding Process: As rotomoulding process LLDPE, HDPE, MDPE, Polythine, Powder are used. LLDPE Plastic Powder is placed inside a cold mould then start to rotate mould inside the heated oven and give heat as much that powder melts and distribute the inner surface of mould and become as one type coted. Now take out the mould outside from heated oven start cooling fan to cool mould during this cooling process keep rotate mould continue until the plastic become in solid form now open the mould & get your product ready to sale.
