Gravimetric Blenders for PP/PS/PET Sheet Extrusion

PP, PS, and PET sheets are everywhere in our daily lives—from food containers and cosmetic packaging to medical trays and electronic components. The sheet extrusion and thermoforming industry plays a crucial role in producing these essential items, but traditional production methods still face inefficiencies.

Challenges in Traditional Sheet Extrusion

1.Bulky Raw Material Storage – Resin pellets and recycled materials take up excessive floor space, creating logistical challenges.

2.Inefficient Manual Mixing – Many factories rely on vertical mixers, which are slow, inconsistent, and labor-intensive. Workers must manually weigh and blend materials, leading to errors and wasted time.

3.Material Waste & Inconsistent Quality – Without precise dosing, improper mixing ratios can result in defective sheets, higher scrap rates, and increased costs.

Our Solutions: Smarter Storage & Automated Blending

To address these issues, we provide:
✔ Indoor Assembled Silos – Compact, modular storage solutions that maximize space and streamline material handling. We can design the silos based on the L*W*H of your material supplying area.

✔ Gravimetric Batch Blenders – High-precision, automated mixing systems that eliminate human error, reduce labor costs, and ensure consistent material quality.

Real-World Case: PP/PS Sheet Production (750 kg/hr)

A customer producing PP/PS sheets at 750 kg/hr faced challenges in maintaining a consistent mix of:

* 50% Virgin Resin

*50% Crushed Recycled Material

*2% Color Masterbatch

*10% Additives

Before using our system, they struggled with uneven blending, frequent downtime for manual adjustments, and high scrap rates. After installing our gravimetric blender, they achieved:
✅ Accurate dosing (±0.5% tolerance) – No more over/under-use of costly additives.
✅ Fully automated mixing – Reduced labor dependency and human errors.
✅ Consistent sheet quality – Lower rejection rates and higher production efficiency.

Upgrade to a Smarter Extrusion Process

By integrating automated weighing and storage solutions, manufacturers can optimize material usage, reduce waste, and improve product consistency—making PP, PS, and PET sheet production faster, cheaper, and more reliable.
