quality assurance
At our company, we place the utmost importance on quality and consistency at every stage of the production process. All components undergo rigorous inspection and testing to ensure they meet strict standards for safety, precision, and performance. Furthermore, through detailed inspection procedures and continuous improvement initiatives, we maintain the quality and stability that our customers trust.
Assembly Service
Our assembly service involves integrating precision-manufactured components into high-quality functional units. Skilled technicians assemble every product within a controlled environment, paying meticulous attention to detail and alignment. By prioritizing efficiency, cleanliness, and consistency at every stage, we ensure the performance and quality necessary to meet the rigorous standards required for medical applications.
Introduction to the Manufacturing Process

Molding
Equipped with three all-electric injection molding machines from Sumitomo Heavy Industries, we manufacture resin products, including medical components for the circulatory system. By maintaining stable molding conditions and high reproducibility, we minimize quality variations and achieve efficient, stable production on a 24-hour basis.
Cut
The molded resin product is placed in specialized cutting equipment, where the product itself is precisely separated from the gate section. The process is carried out carefully and reliably to avoid damaging the product, ensuring consistent quality before handing it over to the next stage of production in optimal condition.
Hard coating
After the cutting process, the resin molded product undergoes hard coating to increase its surface hardness. By applying the treatment uniformly using specialized equipment, we ensure the required durability and surface quality, maintaining consistent standards as the product moves to the next stage of production.
Inspection
During the inspection process, we conduct dimensional and visual inspections to ensure that each product meets established quality standards. We meticulously inspect every single unit visually; this rigorous system, designed to detect even the slightest anomaly or defect, guarantees the consistent quality required for medical components.
Assembly
In the assembly process, skilled technicians carefully and precisely assemble each individual component. Leveraging years of accumulated experience and expertise, they perform efficient, seamless work that boosts productivity while rapidly producing high-quality, consistent products.
Pre-shipment inspection
During the pre-shipment inspection—the final check before products reach the customer—skilled technicians carefully perform a visual inspection of each individual unit. By detecting even the slightest visual irregularities and preventing defective products from leaving the facility, we ensure a level of quality that allows customers to use our products with confidence.
