Production environment
clean room
■ ISO14644-1:2015(International Standard - [cleanliness evaluation]) Production in Class 6 and Class 7 clean rooms
Maintaining cleanliness
■ Periodic particle counter (particulate counter)
■ Compliance with ISO 21501-4
Maintain product quality
■ The temperature, humidity, and other environmental conditions in the clean room are maintained at a constant level.
Manufacturing Method
We require our workers to maintain thorough hygiene, including their clothing.
Mold
Manufactured by two types of injection molding machines: two-color molding machine and single-color molding machine.
〇Production equipment is regularly maintained to ensure quality
TUBE main body uses two-color molding machine
Caps and Racks use mono-color molding machine.
Processing
Processing by automatic machines
Assembly (TUBE, CAP, etc.)
Laser printing
Material quality
Use only“Virgin PP” for TUBE
Virgin PP...non-recycled resin
advantage：
・Reduction of contamination risk
・Assurance of product consistency and quality
・Safe for long-term use
Raw materials are RoHS/REACH compliant.
advantage：
・Free of hazardous substances
・Safety
・Reduction of environmental impact at disposal
