1g/min

Precision Feeding for Global Innovation

Trusted by world-class industries in Battery, Semiconductor, and Materials Science

Our mission

500

Handled material

We have handled more than 500 types of powders and bulk solids,including chemical materials, metal powders, food ingredients, resin powders, and pharmaceutical materials. From free-flowing powders to difficult materials prone to bridging, adhesion, or agglomeration,we provide optimal feeding solutions based on our extensive experience.

To combine Japanese engineering precision with practical design, delivering powder feeding systems our customers can trust for long-term performance.

  ​Ultra-Precision Micro-Feeding for Next-Gen Packaging

Achieves pulse-free, stable feeding at 1g/min. Enhances formulation precision for encapsulants and underfills, ensuring consistent quality for cutting-edge devices.

SUS316L Construction for High-Purity TIM Feeding

Handles abrasive fillers (e.g., alumina) for AI chip thermal management. SUS316L stainless steel provides superior wear resistance, eliminating contamination and preserving material purity.

Tool-less Disassembly for Easy Cleaning

Tool-less structure for rapid cleaning during material changeovers. The dead-space-free design minimizes powder accumulation and contamination risks.

Recent Product

Zero-Contamination Design: Full Access to Every Part.

In semiconductor R&D, even a trace of residue from a previous batch can lead to critical defects. SEIWA’s feeders feature a fully detachable design, allowing every component in contact with the material to be inspected and cleaned. By eliminating hidden dead spaces, we ensure the absolute purity and data repeatability required for advanced material synthesis.

What we do

Empowering R&D and quality control across industries with ultra-precision feeding starting from 1g/min.

Chemical & Materials

Minimize waste of high-value additives. 1g/min precision ensures strict composition ratios, streamlining quality control for multi-product manufacturing.

Battery & Energy

Handling abrasive materials for next-gen batteries. Reliable feeding of solid electrolytes and electrode materials. SUS316L construction prevents wear-induced contamination.

Recycling & Green Tech

From lab-scale to green innovation. Compatible with challenging recycled powders. The compact design allows for instant integration into pilot plants.
