Introduction

Asepto syringes are critical medical devices used for various applications, including the delivery of medications and drawing of fluids. The manufacturing process of asepto syringes requires precision, high-quality materials, and stringent quality control to ensure safety and efficacy.

Asepto Syringe Manufacturing Process

The manufacturing of asepto syringes involves several key steps, each requiring specific conditions and parameters to maintain the integrity and sterility of the final product.

Material Selection

The primary materials used in the manufacturing of asepto syringes include medical-grade polypropylene for the barrel and plunger, and silicone for lubrication. Polypropylene density is typically 0.905 g/cm³, providing the necessary strength and flexibility.

Molding

The molding process involves injection molding machines operating at temperatures between 200°C and 250°C to shape the components. High precision molds are used to ensure the dimensions meet the standards of ±0.1 mm tolerance.

Assembly

The assembly process is automated, comprising the insertion of the plunger into the barrel, and application of silicone lubrication. The fully assembled syringe is measured to ensure that the plunger moves smoothly within the barrel under 1-2 N of force.

Sterilization

Sterilization is achieved through gamma irradiation or ethylene oxide (EtO) treatment. Gamma irradiation typically involves doses between 25 to 50 kGy, while EtO sterilization is conducted using gas concentrations of 450 mg/L at temperatures of 55°C for 3 hours.

Quality Control in Asepto Syringe Manufacturing

Quality control measures are implemented at each manufacturing stage. These include dimensional checks using calipers with precision up to 0.01 mm, and testing for leaks with pressure up to 30 kPa. Each batch undergoes sterility tests to confirm the absence of microbial contamination.
