Contract Manufacturing

Toll Processing

Submit your material. We handle the milling, drying, and classification — with full process documentation and compliance traceability. Ideal for R&D validation, pilot scale-up, and overflow production runs.

What We Offer

Your Material. Our Expertise. Proven Results.

Toll processing means you supply the raw material — we provide the equipment, process know-how, and operational labor to transform it to your target specification. No capital investment in equipment. No facility overhead.

Our contract manufacturing service is designed for procurement managers and technical directors who need to validate a new formulation, fulfill a short-run production order, or bridge capacity gaps without long-term commitments.

  • No minimum equipment purchase -- pay per processed batch
  • Full documentation and certificate of analysis issued per batch
  • Scale from 5 kg trial to multi-ton commercial runs
  • Confidentiality agreements (NDA) available on request

Processing Technologies

Jet Milling

Fluid energy micronization achieving D97 <2μm with no contamination and no heat generation. Ideal for APIs, battery cathode materials, and high-purity chemicals.

  • FinenessD50 0.5-10μm
  • Feed Size<3mm
  • Capacity5kg-500kg/h

Spray Drying

Convert liquid feeds -- solutions, suspensions, emulsions -- into free-flowing powders with controlled morphology and moisture content. Supports encapsulation and co-processing.

  • Outlet Temp60-200°C
  • Particle Size10-300μm
  • Feed Rate1-500 L/h

Impact Grinding

Efficient size reduction using hammer mills and pin mills for medium to fine powder processing. Suitable for food additives, mineral fillers, and bulk chemicals.

  • FinenessD97 20-150μm
  • HardnessUp to 5 Mohs
  • Capacity10kg-2000kg/h

Suitable Material

APIs & Excipients Lithium Battery Cathode Food Additives Pigments & Dyes Ceramic Powders Agrochemicals Mineral Fillers Herbal Extracts Flame Retardants Specialty Polymers
