Plastic & Injection Molding
Injection fume and odour treatment, granulating dust collection and material conveying to hoppers.
Working condition
Recommended configuration
Each row shows the process stage, the machine we normally select and the point that decides whether it performs on site.
| Process stage | Recommended equipment | Selection point |
|---|---|---|
| Injection and extrusion fume | Activated carbon adsorption with catalytic combustionGP-AC Series | Adsorb at low concentration, desorb into a small catalytic combustion unit. |
| Granulating dust | Cartridge dust collector with anti-static mediaGP-LT Series | Anti-static media and explosion venting for combustible polymer dust. |
| Material conveying | Screw conveyor and rotary airlock valveGP-LS / GP-WLS Series | Stainless steel contact parts for food grade and colour change service. |
| Odour at wastewater station | Spray scrubber towerGP-PP / GP-FRP Series | Acid and alkali washing stages per odour component analysis. |
| Workshop energy | VFD retrofit on cooling pumps and fansGP-VFD Series | Closed loop control on cooling water return temperature. |
Energy
Odour and VOCs limits for plastic plants are set by local regulation and receptor distance. Adsorption media replacement interval depends on actual concentration and running hours.
