Buyer's guides, process explainers and industry news for anyone specifying plastic recycling and extrusion equipment — how shredders, washing lines and pelletizing lines are configured around a given feedstock, and which plastics can realistically be recycled at scale.
14 Aug Setting up a plastic recycling plant is seven decisions taken in order — contracted feedstock, capacity, process route, building and utilities, equipment, installation and staffing. This guide works through each one using published SUHUI washing and pelletizing line configurations, so footprint, clear height, installed power, steam demand and operators per shift can be checked against real figures rather than estimated.

13 Aug A washing line is six or seven machines that have to hand material to each other continuously, and almost everything that goes wrong after commissioning happens in the handover rather than inside a machine. This guide covers the six checks that separate a line supplier from a machine supplier — what sits in the gaps between machines, which stages are built in-house, why a line rating is a bottleneck figure rather than a sum, how a whole-line trial is measured as mass balance, who owns a fault that crosses two stages, and whether water, steam and effluent are inside the scope of supply.

13 Aug Plastic recycling equipment selection is a sequence, not a catalogue choice. This guide works through the four inputs that decide a machine list — which polymer you have and what shape it arrives in, how contaminated it honestly is, the throughput you can actually feed, and whether you sell flakes, pellets or finished product — then routes each answer to the size reduction, washing, pelletizing, auxiliary and extrusion equipment it implies, with the six mistakes that recur most often.

13 Aug The numbered triangle on a plastic product is a resin identification code, not a recycling promise. This article explains where the codes came from, what each of the seven stands for, why the same number is collected differently from country to country, and what an industrial sorting line actually reads instead of the printed mark.

10 Aug A plastic recycling machine price is a band, not a number. This guide publishes SUHUI's own factory-direct FOB ranges by machine type, explains the five variables that decide where a project lands inside its band, lists what an FOB figure leaves out, and gives the published utility and labour figures that decide your real cost per ton once the line is running.

06 Aug PET flakes stop being waste and become a traded commodity about two thirds of the way through recycling, with a price per tonne and a specification sheet attached. This guide covers what is on that sheet, which numbers the recycling line produces and which the buyer's contract sets, which stage of a washing line locks in each one, and how to check a lot before you sign for it.

03 Aug A friction washer is the mechanical scrubbing stage in a plastic washing line. This guide covers what it removes from the flake surface, how its job splits with the hot caustic tank and the rinse tank, why its position in the sequence changes between film and bottle streams, and what it cannot fix at any setting.
