A syringe mould is a complex tool that is used to shape the plastic or glass components of a syringe. It consists of several parts, each serving a specific function:
1. Cavity: The cavity is the space within the mould where the syringe barrel is formed. It is designed to match the exact dimensions and contours of the final product.
2. Core: The core is the part of the mould that forms the internal features of the syringe, such as the bore that houses the needle.
3. Runner System: This system channels the molten plastic from the injection unit to the cavity. It must be designed to minimize material waste and ensure even distribution of the material.
4. Gates: Gates are the entry points for the material into the cavity. They are crucial in controlling the flow and pressure of the material, which affects the quality of the final product.
5. Ejection System: After the syringe component has cooled and solidified, it must be removed from the mould. The ejection system, often consisting of pins or plates, is responsible for this.
Manufacturing Process
The manufacturing of medical syringe moulds is a highly specialized process that requires precision and adherence to strict quality control standards:
1. Design and Simulation: Before any physical manufacturing begins, the mould is designed using CAD software. Simulations are run to test the flow of material and to identify any potential issues in the design.
2. Machining: The mould components are then machined from blocks of high-grade steel or other materials. This process is carried out on computer numerical control (CNC) machines for precision.
3. Heat Treatment: To ensure durability and resistance to the high pressures and temperatures involved in the injection moulding process, the mould components undergo heat treatment.
4. Assembly: The individual components are assembled into a complete mould, with careful alignment to ensure proper function.
5. Testing and Quality Control: The mould is tested with actual production runs to ensure it meets the required specifications. Any deviations are corrected, and the mould is certified for use in medical syringe production.
