Plastics & Rubber

Materials We Handle — Pellets, Powders, Regrind or Rubber Crumb

Materials handled include PE, HDPE and PVC pellets, engineering resins, masterbatch, additives, fillers, powders, flakes, regrind, carbon black and synthetic rubber crumb. Each material behaves differently during storage, conveying and dosing, so the system must maintain reliable flow, prevent contamination and dust release, protect product quality and support stable production.

Non-Degrading Conveying & Process Flow Control

Non-degrading conveying and process flow control protect fragile pellets, regrind, flakes and rubber crumb during transfer, dosing and discharge. Correct conveying velocity, smooth pipework, suitable bends and controlled feeding help reduce breakage, fines, angel hair and material segregation while maintaining consistent flow, product quality and reliable downstream processing.

Pneumatic & Mechanical Conveying for Polymers

To transport polymer pellets and fine powders without material degradation, our pneumatic conveying systems utilize dilute or dense-phase transport with specialized internal surface treatments to prevent friction-induced heat. This completely eliminates the formation of “angel hair” or streamers that clog lines. For masterbatches and rubber compounding additives, our enclosed mechanical conveying lines ensure safe, dust-tight transfer.

Wear-Protected & Ceramic-Lined Process Piping

High-speed pneumatic routing of fiberglass-filled resins or highly abrasive rubber crumb causes severe pipe erosion. We utilize specialized wear protection piping featuring processed internal areas or ceramic-lined bends to resist abrasive wear while keeping the material stream completely free from metal flake contamination.

Slide Gates, Rotary Valves & Diverters

Our rotary valves feature quick-demount rotors to eliminate cross-contamination between batches. Accompanying pneumatic slide gates and multi-port diverters provide positive, airtight isolation and reliable stream routing beneath blending silos and extruders without trapping pellets in the seals.

Separation, Screening & Precision Blending

Vibrating Screens

Positioned directly after extruders or underwater pelletizers, our high-frequency vibrating screens efficiently dewater and classify polymer pellets, removing oversized agglomerates, longs and fine particulates to ensure a uniform, market-grade product size.

Weighing, Dosing & Feeding Equipment for Compounding

For complex compounding and masterbatch lines, our high-precision loss-in-weight feeders and gravimetric weighing equipment provide continuous dosing of resins, colorants and plasticizers, ensuring exact recipe consistency and preventing material waste.

Inline Magnetic Separation for Purity Assurance

To maintain strict automotive and medical-grade purity standards, high-intensity magnetic separators are integrated inline to continuously extract ferrous contaminants from plastic flakes, regrind and additives.

Dust-Free Containment & End-of-Line Packaging

Big Bag Filling & Emptying Units

Managing raw polymers and carbon black in bulk bags requires specialized handling. Our FIBC emptying stations use pneumatic massage paddles to overcome the bridging tendencies of sticky rubber crumb or fine PVC powder, while our filling stations utilize inflatable, dust-tight neck seals to ensure safe, clean filling.

Telescopic Loading Chutes

For high-volume logistics, our telescopic loading chutes extend directly into bulk railcars or tanker trucks. They utilize internal double-wall cones and negative pressure dust collection to enable high-speed gravity loading while completely preventing light polymer pellets from escaping into the environment.

Packaging, Palletizing & Wrapping

To prepare finished plastics and compounding materials for global shipping, automated packaging lines form and seal products into moisture-barrier bags. These are fed to automatic palletizers that assemble perfectly square stacks despite fluctuating bulk densities, followed by automated stretch-wrapping or stretch-hooding units that apply multi-layer film tension for maximum load stability and weatherproof yard storage.
