Production facilities
clean room
ISO 14644-1:2015 (international standard for cleanroom classification) Manufactured in Class 6 and Class 7 cleanrooms
Maintaining cleanliness
Periodic particle counter checks
Compliance with ISO 21501-4
Maintain product quality
Temperature, humidity, and other environmental conditions in the cleanroom are maintained at controlled levels.
Manufacturing process
We require our workers to maintain thorough hygiene, including their clothing.
Mold
Manufactured using two types of injection molding machines: a two-color molding machine and a single-color molding machine.
Production equipment is regularly maintained to ensure consistent quality
The TUBE body is produced using a two-color molding machine.
Caps and racks are produced using a single-color molding machine.
Processing
Automated processing
Assembly of TUBE, CAP, and related components
Laser printing
Materials
Use only Virgin PP for TUBE
Virgin PP: non-recycled resin
Advantages:
・Reduced risk of contamination
・Consistent product quality and reliability
・Suitable for long-term use
Raw materials are RoHS/REACH compliant.
Advantages:
・Free from hazardous substances
・Safer handling
・Reduced environmental impact at disposal
