Stage 1 – Sorting  [ Watch Video] (3,729 Kb)

Before we can recycle the plastic wastes, we need to ensure that the plastics are being sorted according to each specific type, especially if we are dealing with mixed or commingled plastic wastes. We have an automated plastic sorting system in our factory that is able to process up to 2 tonnes of plastic materials per hour.
Besides sorting the plastic materials to each specific type, we also need to ensure that the plastic wastes are free from contamination of other materials such as paper, metal, wood, organic wastes, etc.

Stage 2 – Size Reduction [ Watch Video] (2,102 Kb)

The plastic wastes come in different shapes and sizes. We need to use machines such as Shredder and Crusher to reduce the materials to a size of about 10mm. The purpose is to ensure a smooth and constant flow of the plastic wastes into the plastic extruder machines.

Stage 3 – Blending

The crushed plastic materials could be of different quality and grade. In order to achieve a homogenous batch of recycled materials with the same quality, we need to blend the crushed materials so that the materials are evenly distributed. This is done in our factory with our blending and tumbling machines.

Stage 4 – Extrusion [ Watch Video ] (3,923)

After blending, the materials are now ready for extrusion. Extrusion is a melting process where the materials are fed into a hopper and melted in the heated barrel with rotating screws. During the melting process, additives (e.g. antioxidant, impact modifier, lubricant, calcium carbonate, talc) are sometimes added to aid the extrusion process or modify the plastic properties. The rotating screws will mix and push the melted materials out of the die opening in strands. These strands travel through a water tank to cool and solidify.

Stage 5 – Cutting and Packing

At the end of the water tank, the strands are cut into pellets by a pelletiser. Non-uniform (either undersized or oversized) pellets are sieved out by the shifter. The remaining pellets are conveyed into storage tanks and then packed into 25kg

Stage 6 – QC Testing

All our finished products go through comprehensive and stringent tests to ensure that its quality meets customers’ requirements. These tests are done by our QC Department using the full range of equipment and instruments in our laboratory. Our tests conform to ASTM standards and we are able to produce the relevant test specifications or certifications such as RoHS certification.
